MicroCurrent HVLD Technology for CCI Testing of Parenterals

MicroCurrent HVLD Technology for CCI Testing of Parenterals

Container Closure Integrity Testing is a leak detection test conducted using non-destructive package inspection systems, to evaluate whether container closure systems can maintain sterile barriers against potential damages. CCIT plays a vital role in ensuring that the products are free from any possible contamination. Container closure systems are made up of primary packaging components and secondary packaging components. Components like glass, vials or syringes that are in direct contact with the product are called primary packaging components. Secondary packaging components include aluminum caps, cardboard boxes etc. that are not in direct contact with the product.

While there are multiple ways to conduct a Container Closure Integrity test, these methods can be broadly classified into probabilistic and deterministic test methods. Traditional methods like bubble tests, dye ingress and microbial challenge by immersion come under probabilistic test methods. Since it was found that such test results lacked accuracy and reliability, the United States pharmacopeia released guidance in 2016 stating that deterministic methods are preferred over probabilistic test methods. Let us now understand how Microcurrent HVLD technology ensures sensitive CCI testing across different industries and applications.

MicroCurent HVLD technology is a non-destructive test method capable of achieving high levels of CCI assurance across the entire range of parenteral products. It is an FDA recognized ASTM test method capable of detecting the presence and location of pinholes, micro-cracks, stopper/plunger leaks, non-visible leaks under crimping and many other defects. Additionally, MicroCurent HVLD technology is found to be effective in detecting leaks in a wide range of liquid- filled products including extremely low conductivity sterile water for injection (WFI) and proteinaceous products with suspensions. A unique feature of Microcurrent HVLD technology is that it does not require mass to pass through a defect site, requiring only the passage of electricity through a crack.

How does MicroCurrent HVLD technology work?

MicroCurrent HVLD technology functions on the simple property of electrical current. The first step is to place container horizontally on the rotating stage. While rotating the container, high voltage is applied on one side of the container and a ground probe on the opposing side. In the presence of a micro-leak or crack in one of the container walls, break-down resistance is reached and the current passes through. On the other hand, if there is no leak, the two container walls (high voltage side and ground side) provide full electrical resistance and no significant current is measured passing through the package.

MicroCurrent HVLD reduces voltage exposure to the product to less than 5% of the voltage exposure experienced when testing with other HVLD solutions. Reduced voltage exposure has twin benefits- limits any risk that the voltage may cause to the product, and greatly reduces production of ozone during operation. In fact, experiments have shown that MicroCurrent HVLD produces essentially no Ozone

Reasons Behind Choosing Non-destructive Methods for Pharmaceutical Package Testing

Reasons Behind Choosing Non-destructive Methods for Pharmaceutical Package Testing

In the pharmaceutical industry, the integrity of packaging plays a pivotal role in ensuring the safety, efficacy, and quality of medications. Packaging serves as a barrier that protects pharmaceutical products from external factors, such as moisture, air, light, and contaminants, which could compromise their stability and effectiveness. Ensuring the integrity of pharmaceutical packaging is not only crucial for regulatory compliance but also for maintaining patient safety and confidence in the products.

Traditional methods of package testing often involve destructive techniques, where samples are opened, punctured, or otherwise altered for assessment. However, these methods come with inherent drawbacks, including product wastage, the need for additional samples, and prolonged testing times. To address these challenges, the pharmaceutical industry has increasingly turned to non-destructive methods for package integrity testing.

What are the Non-destructive Methods Used for Pharmaceutical Package Testing?

Vacuum Decay Technology

Vacuum decay is a non-destructive Container Closure Integrity Test (CCIT) that provides reliable, repeatable, reproducible, and accurate results along with clear pass/fail quantitative data. The basic idea of Vacuum decay technology is to question the integrity of containers based on their fundamental physical properties. Sample packages are initially placed within a tightly sealed evacuation test room with an external vacuum source. Based on the test sample and the needed level of sensitivity, a predetermined vacuum level is selected. The test chamber and test system dead space must be evacuated after that for a certain period of time. To monitor variations in vacuum level over time, differential pressure transducers are utilized. The container is leaking if the pressure rises over the designated pass/fail limit.

Volumetric Imaging Technology

Non-destructive leak detection of blister packages is done using OptiPac One-Touch Tool-less technology. The OptiPac uses volumetric imaging technology to monitor the movements of a blister package while it is under vacuum in order to identify leaks. The interface is practical and simple to set up with new blister package forms, necessitating no tooling changeover or significant parameter revisions as with previous non-destructive blister package inspection systems. In response to different cavity shapes, sizes, and combinations of various blister pack types, the system gathers volumetric data from each cavity.

Airborne Ultrasound Technology

Airborne ultrasound is a deterministic test technique for seal quality inspection in materials including aluminum, foil, paper, plastic, poly, film, and Tyvek. It has been proven to be one of the most effective non-destructive testing techniques for flexible package seals. According to studies, conventional seal inspection methods are ineffective because they miss undetectable defects and incorrectly reject pouches that are tightly sealed. On the other hand, Airborne ultrasound technology has been successful in both online and offline solution options. Airborne ultrasound is a typical test method for evaluating seal quality and integrity in accordance with ASTM F3004-13.

Microcurrent HVLD technology

High Voltage Leak Detection, often known as HVLD, is a deterministic, non-destructive leak detection technique used to evaluate the Container Closure Integrity of vials, cartridges, and other liquid-filled parenteral products. It is one of the most efficient approaches for online container closure testing. MicroCurrent HVLD uses around 50% less voltage and exposes the product and environment to less than 5% of the voltage when compared to standard HVLD systems. This technique doesn't require sample preparation and is non-invasive. Pre-filled syringe testing is one of the main uses of MicroCurrent HVLD, along with vial leak testing.

Non-destructive Package Integrity Testing Method Benefits

Non-destructive package integrity testing holds significant importance in the pharmaceutical industry due to the critical nature of pharmaceutical products and the strict regulatory requirements in place. Here are some key benefits of using non-destructive package integrity testing in the pharmaceutical industry:

  • Product Safety: Ensuring the integrity of pharmaceutical packaging is paramount for product safety. Non-destructive testing methods can identify leaks, defects, or breaches in packaging that could lead to contamination, spoilage, or compromised efficacy of the medication.
  • Regulatory Compliance: The pharmaceutical industry is heavily regulated to ensure patient safety and product quality. Non-destructive package integrity testing helps companies meet regulatory requirements outlined by agencies such as the FDA (U.S. Food and Drug Administration) and other international regulatory bodies.
  • Reduced Risk of Contamination: Non-destructive testing methods can detect micro-leaks or breaches in packaging that may not be immediately visible to the naked eye. This reduces the risk of contamination from external factors like air, moisture, or pathogens.
  • Preservation of Sterility: Many pharmaceutical products require a sterile environment to maintain their efficacy and safety. Non-destructive testing ensures that the packaging's sterile barrier is intact, preventing any potential breach of sterility.
  • Enhanced Product Quality: Maintaining package integrity helps prevent degradation of pharmaceutical products caused by exposure to light, moisture, or air. This ensures that medications maintain their intended potency and effectiveness.
  • Cost Efficiency: Non-destructive testing methods save costs by preventing the need for destructive testing, which would require additional samples for analysis. This also reduces the need for retesting, minimizing waste and resource consumption.

As the demand for stringent quality control and regulatory adherence in the pharmaceutical sector continues to grow, understanding the nuances of non-destructive package testing methods becomes essential. By adopting these innovative techniques, pharmaceutical manufacturers can uphold their commitment to patient safety, product efficacy, and overall excellence in the field.

Techniques Involved in Leak Testing Pharmaceuticals

Techniques Involved in Leak Testing Pharmaceuticals

Leak testing is an essential process in the pharmaceutical industry to ensure the safety and quality of the products. The purpose of leak testing is to detect any leaks or defects in the packaging, that could compromise the integrity of the product.

There are different methods of leak testing available, and the choice of method depends on various factors, including the type of packaging, the product being packaged, and the desired sensitivity of the test. Some of the commonly used methods for leak testing in the pharmaceutical industry are:

Vacuum Decay Technology

Vacuum Decay is a non-destructive container closure integrity test (CCIT) method that focuses on package integrity and detecting leak paths. Compared to manual inspection and other non-deterministic test methods, Vacuum Decay measurements offer deterministic and reliable test results to ensure package integrity. Vacuum Decay technology can accommodate a wide variety of packaging formats, including filled and sealed rigid, semi-rigid, flexible, non-porous or non-porous materials. This test works by placing packages in a well-equipped evacuation test chamber with an external vacuum source. Vacuum levels are continuously monitored to detect any deviations from predetermined targeted vacuum levels. A defect in the package can cause air to escape from the package into the test chamber. On the other hand, defect-free packages hold in air by maintaining a constant chamber vacuum level. Vacuum Decay technology has proven over the years to be one of the most practical and sensitive vacuum-based leak detection solutions.

MicroCurrent HVLD Technology

High Voltage Leak Detection (HVLD) is a non-destructive container closure integrity test (CCIT) for evaluating parenteral product packaging integrity. The concepts of quantitative electrical conductivity measurement are used in HVLD technology. HVLD is based on the fundamental nature of electric current. The package barrier must be non-conductive and prevent the flow of electricity, while the package contents must generally be able to carry voltage. The container is placed horizontally on the rotating stage. As the container rotates, a high voltage is applied to one side, and a ground probe is attached to the opposite side. If the package does not leak, the two container walls (high voltage and ground) offer complete electrical resistance and will not record significant current as it travels through the bottle. Breakdown resistance is encountered if there is a micro-leak or crack in one of the container walls and the current passes through. Examples of high-voltage leak detection technology applications include pre-filled syringes, ampoules, drug product cartridges, liquid-filled vials, and blow-fill-seal (BFS) containers.

Force Decay Technology

Force Decay is a quantitative leak detection method that works particularly well with low-headspace packaging. Non-porous materials such as foils, laminates, and films can be used for packaging types. Since it is a non-destructive test procedure, the sample packets are not harmed or changed. Packages do not need to be discarded away when the test is over; they can be added back to the batch. The test system use nested tooling to place the package in the same place and to prevent unmeasured extension of the package under test. Once the test is started, a vacuum is drawn onto the test chamber, which causes the package to expand inside the chamber. The ASTM F2338 vacuum decay leak test technique monitors vacuum levels during the test cycle to evaluate the package. The expansion of the package being tested applies force to the VeriPac force measurement system.

Volumetric Imaging Technology

OptiPac Leak Detection System is one of the deterministic non-destructive package integrity test solutions made especially for blister packs. The One-Touch Technology used in the design and engineering of OptiPac allows for a quick test cycle without the need for sample preparation or changeover. Depending on the size of the blister cavity, this unique technique can quickly identify defects less than 5 microns. Although the OptiPac system employs similar concepts to those used in a vacuum-based blue dye test, it uses controlled inputs and monitored outputs without the hassle and reliability issues of the dye ingress technique. To identify leaks, OptiPac use volumetric imaging technology to measure the motion of a blister package while it being vacuumed.

It is important to note that leak testing should be done at various stages of the packaging process, including before and after filling, and during storage and transport. Proper leak testing can help ensure that the pharmaceutical product is safe and of high quality, which is crucial for patient safety.

Companies that once relied on probabilistic techniques like the blue dye test are now aiming to use a more reliable and predictable procedure for integrity testing of various package formats. The pharmaceutical industry is getting ready to adapt to the deterministic testing world in order to enhance quality, increase efficiency, and comply with changing regulatory standards.

Overview of Airborne Ultrasound Technology

Airborne ultrasound technology is a seal quality inspection technique. It is an ASTM test method F3004, the FDA approved standard for seal quality testing. Such tests are mainly performed to provide enhanced seal quality testing of pouches, flexible packages and tray seals. Airborne ultrasound technology ensures in-depth seal quality analysis and applies to multiple packaging materials including Tyvek, paper, foil, film, aluminum, plastic and poly.

In this technique, sound waves are reflected when ultrasound waves pass through the package seal. Signal strength is reduced or eliminated in the presence of leakage / fault. Such deviations are closely monitored to detect leakage. The inability to detect non-leak defects is a common challenge faced by most leak test methods. However, with Airborne ultrasound technology, users can identify various types of seal defects; visible and invisible, leaky and non-leaky, process-related and random.

Seal-Scan and Seal-Sensor Technology

Seal-Scan and Seal-Sensor are the two variants of Airborne ultrasound technology that utilizes non-contact airborne ultrasonic testing technology. With advancements in the form of seal-scans and seal-sensors, Airborne ultrasound technology has proven to be the most effective method for non-destructive seal integrity testing in both offline laboratory testing for seal quality analysis and 100% inline testing on the production line.

CCI Testing of Intravenous Bags Using Vacuum Decay Technology

CCI Testing of Intravenous Bags Using Vacuum Decay Technology

Container closure integrity (CCI) testing of intravenous (IV) bags is an important quality control measure to ensure the safety and efficacy of the products. CCI testing helps verify that the container closure system, including the bag and its closure, maintains its integrity throughout the product's shelf life and prevents any leakage or contamination.

Various methods, including visual inspection, dye immersion testing, bubble emission testing, headspace gas analysis, and Vacuum decay testing can be employed to assess the integrity of the container closure system. These methods help to identify any defects or breaches that may compromise the sterility and stability of the IV bags. Manufacturers should select an appropriate method based on their specific requirements and regulatory guidelines to ensure the quality and safety of the IV bags.

Vacuum Decay Technology for CCI Testing of Intravenous Bags

Vacuum decay technology is an FDA-approved leak detection technique that can be used for CCI testing of high-risk package applications. The non-destructive nature of the process allows for greater understanding of packages, testing at a greater frequency with more accuracy and with less waste. Vacuum decay technology is capable of detecting leaks in sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials and has been proven to provide repeatable, reliable and quantitative test results.

VeriPac testing systems using Vacuum decay leak testing are highly effective for leak testing of IV bags. Using a differential pressure transducer leak test system, the test method is capable of detecting package leaks and invisible defects in the IV bag body and also in seams, welds and port areas. This method is non-invasive, non-subjective and does not require sample preparation.

The test method works by connecting the VeriPac test systems to a manually operated test chamber containing an IV bag. The next step is to draw a vacuum on the IV bag in the test chamber and observe any changes in the vacuum level. If there is any damage to the package, air or liquid will flow from the package into the chamber, causing pressure fluctuations. On the other hand, defect-free packages do not leak any pressure into the chamber, keeping the chamber vacuum level constant. Regardless of the location of the defect, the vacuum decay system can pick up both large and small defects. It takes about 30 seconds for testing IV bags, repeatable and sensitive to 15 microns for liquid and gas leaks.

Benefits of Vacuum Decay Technology

  • Eliminates destructive, subjective testing methods.
  • Non-destructive technology.
  • Accurate, repeatable results.
  • Pass/fail results backed by quantitative test data.
  • Eliminates destructive, subjective testing methods.

It is designed with One-Touch Technology to accomplish a quick test cycle needing no changeover or tools for various blister formats. Unlike other non-destructive blister package inspection systems that demand complicated parameter modifications, OptiPac requires no tooling replacement with new blister package forms.

The test begins by placing the sample on the testing area for vacuum-based measurement. Vacuum is pulled to a definite vacuum after pushing the start button. Under vacuum, blisters expand and push air out of the blister through any leaks that may be present. If there is a leak in the blister, air leaks into the chamber and collapses the blister package. The defective blister cavities are identified using a volumetric measurement reading during the dynamic vacuum test cycle. Along with the quantitative measurement related to each package test, a clear pass/fail result is displayed.

Functions Offered by OptiPac's Insightful Technology

  • Auto configuration for easy recipe setup and validation of new blister formats.
  • Auto orientation of blister packs (test blister packs in any position –no specific orientation).
  • Auto calibration is an integrated one-touch function.
  • Advanced batch reporting with audit trail including image of blister pack and defect results.

OptiPac Benefits

  • Non-destructive technology - Pass/Fail results backed by quantitative test data.
  • Completely tool-less.
  • No changeover to test different blister formats.
  • Identifies defective cavity.
  • Pre-loaded recipe library with easy recipe setup and validation of new blister formats.

In addition to selecting the appropriate method for leak testing, other factors to consider when performing blister package leak testing include the type of material used for the package, the seal strength of the package, the packaging process, and the potential for environmental factors to affect the package's integrity. By carefully considering these factors and implementing an effective leak testing (pharmaceutical package testing) process, pharmaceutical companies can ensure that their products are of the highest quality and meet regulatory requirements.

Package Integrity Testing of MAP (Modified Atmosphere Packaging) Using VeriPac Series

Package Integrity Testing of MAP (Modified Atmosphere Packaging) Using VeriPac Series

Meat processors are relying on technologies to extend product shelf life more than ever before, which puts concerns like shelf-life stability and packaging quality to the forefront of challenges. Although meat-based snack products and pet products come in a variety of packaging formats, they all require package integrity assurance/container closure integrity testing for extended shelf life.

Flexible packaging, particularly pre-made pouches and form-fill-seal pouches and bags, is the most preferred format for meat-based snack foods and pet food products. With its capacity to provide shelf stability and ease of opening, flexible packaging makes for the best package appearance. The market for meat products for animals has grown rapidly, as consumers are willing to spend more and demand higher-quality products. Meat snacks intended for animal consumption as well as human use must be free of mold or product deterioration.

Modified Atmosphere Packaging (MAP) tray packs are a common packaging option for fresh beef, hog, and poultry products as well as many other processed meats. By significantly reducing spoilage and extending shelf life, the MAP method provides consumers with fresh items that look good. Once an MAP package is sealed, it is essential to maintain the seal integrity to avoid leaks that can let O2 or other environmental pollutants enter the package.

Explain MAP

Modified Atmosphere Packaging (MAP), which can detect leaks as small as 10 microns, is widely used for perishable products. Package integrity can be tested by monitoring the amount of residual oxygen in the headspace of the package. According to the method, the product must be set up for stability and the headspace must be measured at various time intervals. The six-day test, which frequently measures O2 levels over the maximum threshold (about 3%), is used for production purposes. A 50-micron defect significantly reduces a product's shelf life, but it typically passes a six-day O2 test with flying colors. Six days of output are already palletized and stored in case the O2 test identifies a quality issue. Vacuum Decay can find breaches as small as 10 microns, detect oxygen-critical defects in real time at the source, and prevent extensive quality issues.

VeriPac Series for Testing MAP Meat Packages

The VeriPac Vacuum Decay Series of inspection systems have a proven capacity to non-destructively test packaging down to O2 sensitive leak sizes, which reduces waste and enhances testing capabilities. By consistently detecting leakage as tiny as 10 microns, the technology may identify process issues before they become critical. VeriPac offers quantitative data that is correlated to leak rate and leak size in addition to a clear attribute result (PASS or FAIL).

The VeriPac D-Series uses a revolutionary FLEX-Chamber to test flexible packaging formats since it is resistant to package changes and removes the requirement for changeover when testing different size pouches. Additionally, more than one package may be tested during a single test cycle. The VeriPac Series utilizes a rigid packaging test chamber for MAP Meat Tray Package testing. Depending on the needs of the production, the test system operation can be set up for either semi-automatic or manual operation.

Advantages of VeriPac Series

  • Non-destructive, no sample preparation.
  • Deterministic, quantitative test method.
  • Defect detection down to 0.2 ccm.
  • High level of sensitivity, repeatability and accuracy.
  • Short cycle time provides operators with PASS/FAIL results.
  • Small footprint and modular portable design.
  • ASTM test method and FDA standard.
  • Referenced in USP 1207 guidance.

Since it eliminates subjective results, the VeriPac series is a practical alternative to destructive testing. Case studies have proven that Vacuum decay leak testing technology offers a rapid return on investment when evaluating the dramatic decrease in waste created by destructive test techniques.

Powdered Dairy Products Package Testing Using VeriPac FLEX Series

Powdered Dairy Products Package Testing Using VeriPac FLEX Series

The sensitivity of a test method is necessary for several reasons, but it is most crucial in ensuring the final product is of high quality. Powdered dairy products (milk powders, infant formula, protein-based powders) are kept in a modified environment to avoid spoilage and maintain the nutritional value of the product throughout its shelf life. Before usage, the product will quickly deteriorate due to oxygen and moisture intrusion, affecting the flavor and texture and finally converting any desirable commodity into a liability. The quantity and impact of oxygen ingress depend on a number of variables, and it will occur in the presence of tiny leaks. Leaks as small as 10 microns will have an immediate impact on the product for smaller packaging types. Current conventional test techniques are completely insufficient for identifying such defects, leaving manufacturing operations exposed to severe quality variations. Applying techniques with greater sensitivity provides the highest level of quality assurance, rather than just locating minor leakage.

Ensuring Dairy Products Package Integrity with VeriPac FLEX Series

For pouches and other flexible packaging, VeriPac FLEX systems are versatile non-destructive package inspection systems. These are available in a variety of configurations for the leak test instrument and the test chamber capacity, with solutions to accommodate small format sachets and stick packs up to bulk size pouches and bags.

A Complete Guide to Helium Leak Detection Technology

A Complete Guide to Helium Leak Detection Technology

The quality of the product and the maintenance of the sterile barrier against outside forces are both critically dependent on the packaging. Even a tiny hole in the packaging might allow moisture, reactive gases, or other dangerous elements to enter the product, limiting its ability to heal. Additionally, a contaminated pharmaceutical product can cause serious health issues to the user, making it more of a threat than a treatment. Maintaining Container Closure Integrity is extremely important due to the sensitive nature of pharmaceutical products.

Container Closure Integrity testing is a leak detection technique for determining how well sterile barriers are maintained against external contamination. These tests may be roughly divided into probabilistic and deterministic test methods. Manufacturers choose deterministic test procedures since they provide precise, guaranteed quantitative results. One such test method is helium leak detection technology.

Helium Leak Detection Technology Overview

Helium leak testing is the method of identifying leaks in various enclosed or sealed systems by utilizing helium as a "tracer" gas and measuring the concentration of the gas as it leaves due result of a leak. A vial is a good example of package system. A pre-filled syringe, a foil pouch, and a cold form blister card are some other examples. Each of these package types is intended to keep the pharmaceutical product contained while preventing the entry of potentially dangerous environmental contaminants like dust, bacteria, or even gases. Helium leak testing method can evaluate these package types. It is a highly efficient approach for finding leaks that provide quantitative leak rate data considerably beyond the capabilities of existing leak testing techniques.

The following describes how helium leak detection works: The package is initially vacuumed and helium-filled. The amount of helium escaping the package is then measured quantitatively and expressed as a leak rate using a helium leak detector. The technique is also ideally suited for packaging line setup and validation, failure analysis, tool qualification, monitoring product quality, and package design.

Why Use Helium as a Tracer Gas?

There are several reasons why helium is considered an ideal test gas for finding leaks.
  • Deterministic seal quality inspection method that produces quantitative outcomes.
  • Regardless of color, transparency, print, surface polish, or porosity, this method works for all material types and combinations.
  • Non-destructive and non-subjective test technique that does not require any sample preparation.
  • Technology may be used for 100% online final pouch seal defect detection.
  • Seal quality inspection results are repeatable, reproducible and reliable.
  • Cost-effective solution for testing seal integrity and seal analysis that characterizes the overall quality and uniformity of the seal.

Helium Leak Detection Merits

  • Practical and sensitive flow-based leak test method.
  • Enables the discovery of extremely small microleaks.
  • Detects leaks with sensitivity levels as low as 1x10-10 mbar L/sec.
  • Helium is a non-explosive, non-toxic and non-destructive tracer gas.
  • Applicable across package design, failure analysis, packaging line setup and validation.
  • Faster test cycle reduces cost and total processing time.

Applications of Helium Leak Detection

  • Vials
  • Pre-filled syringes
  • Blister packs
  • Combination products
  • Bottles
  • Foil pouches

Helium leak detection is the best option for evaluating the inherent integrity of specific primary container closure systems of pharmaceutical and parenteral products. It is a commonly used technology in early stage pharmaceutical package development and component compatibility evaluation. In comparison to other leak test techniques, helium leak testing has the highest level of sensitivity, making it the most used CCI test method. In accordance with ASTM F2391, helium leak detection is a widely used method in the pharmaceutical industry.

Applications of Vacuum Decay Technology

Applications of Vacuum Decay Technology

Vacuum Decay is a non-destructive method for testing the integrity of container closures for package integrity and leak path detection. The technology provides quantitative, deterministic, and reliable test results to assure package integrity in comparison to manual inspection and other non-deterministic test techniques. The vast range of package types that may be accommodated by Vacuum Decay technology includes filled and sealed rigid, semi-rigid, and flexible packaging consisting of non-porous or porous materials.

Vacuum Decay Technology

Vacuum Decay is one of the most efficient and accurate vacuum-based leak detection methods. The method operates by placing the package within a properly outfitted evacuation test chamber that contains an external vacuum source. To detect any deviations from a predetermined targeted vacuum level, the vacuum levels are continually monitored. If there is a defect in the packaging, air or liquid will leak into the chamber from the package and cause a change in pressure. On the other hand, non-defective packages do not leak any pressure into the chamber, maintaining the chamber vacuum level constant. The test cycle is quick, non-invasive, and non-destructive to both the product and the container. The Vacuum decay system can detect both major and minor defects, regardless of where they are located. The system has various applications in the field of pharmaceuticals and medical devices.

Applications of Vacuum Decay Technology in Various Industries

  • Pharmaceutical
  • Pharmaceutical products are a range of substances used for treating, diagnosing, or changing organic processes to help the management of public health. Pharmaceutical products are tested to make sure they adhere to strict safety and quality requirements. Previously, pharmaceutical packaging was only subjected to sterility testing. However, the United States has recognized that sterility testing alone is not sufficient to maintain the integrity of pharma products. FDA (Food and Drug Administration) has published guidance related to pharma industry on submission of documentation for sterilization process evaluation in human and veterinary drug products.

    Container closure integrity (CCI) testing is a non-destructive package inspection technology for finding leaks and avoiding potential contamination. A test like this is necessary since any defect in the container might allow foreign particles to enter the product and thereby reduce its shelf life. Since it impacts both the product and the patient, a manufacturer places high priority on implementing the proper container closure system. Thus, the relevance of container closure integrity testing in the pharmaceutical industry has increased substantially over time. Vacuum Decay and MicroCurrent HVLD are the most chosen technologies for testing pharmaceuticals.

  • Medical Device
  • Maintaining medical device package integrity is essential to make sure the product is delivered to the end user unharmed. Medical device packaging and delivery options range from rigid non-porous containers to flexible porous packaging. Every packaging format has a different set of characteristics and requirements, so choosing the right inspection technique requires a thorough approach. Package challenges have risen along with packaging format and material innovations. Among all medical equipment, Class III devices produce the greatest risk to maintaining package integrity. These implanted devices preserve or maintain life. Pacemakers, cardiovascular stents, respiratory ventilators, and breast implants are a few examples of Class III medical devices. Since these devices are inserted into human bodies directly, even a small packaging defect puts patient’s safety at risk. Therefore, it is essential to evaluate the container closure integrity of medical devices.

Vacuum Decay Technology Benefits

  • Non-destructive, non-subjective and does not require sample preparation.
  • Detection of defects down to 0.01 cc/min.
  • Results show that they are more accurate than dye ingress.
  • Quantitative, deterministic testing technique.
  • Supports initiatives for waste reduction and sustainable packaging.
  • ASTM test method and FDA recognized standard.

When determining the integrity of pharmaceutical and medical devices, Vacuum decay leak testing is the best non-destructive option. The test measurement generates a reliable and accurate quantitative result, as well as a pass or fail decision. The FDA recognizes the standard Vacuum Decay leak test technique (ASTM F2338) as a consensus standard for evaluating container closure integrity (CCI). The test technique is referenced in the United States Pharmacopeia Chapter on CCI (USP Chapter 1207) and listed in ISO 11607.

Package Integrity Testing Systems for Porous Packaging

Package Integrity Testing Systems for Porous Packaging

For packaging sterile devices in the medical industry, porous packaging materials are widely used. The sterile products are frequently packaged, shipped, and distributed to multiple places, where they may be exposed to a range of humidity conditions during the course of the distribution cycle. The leaks in the porous packaging materials can contaminate medical devices as well as products. These leaks are frequently observed at tiny pinholes or breaches in the seals between packing components. Hence, maintaining the microbial barrier of sterile medical devices is of grave importance. In order to maintain the sterility and microbial barrier, various package integrity test solutions can be used. Airborne Ultrasound technology is one such method.

Airborne Ultrasound Technology Overview

Airborne ultrasound is an inspection method for testing seal quality that is able to evaluate seals for defects without causing any damage. It is an FDA recognized standard and ASTM Test Method F3004 for testing seal quality. Such tests are mostly carried out to provide enhanced tray seals, flexible packages, and pouch seal quality inspection. Tyvek®, paper, foil, film, aluminum, plastic, and poly are just a few of the packaging materials that may be used with Airborne Ultrasound technology to ensure in-depth seal quality analyses.

Integrity Testing of Porous Packages using Airborne Ultrasound Technology

Airborne Ultrasound technology is one of the commonly used methods for testing the seal quality of porous packages. In this technique, sound waves are reflected when ultrasound waves pass through the packaging seal. The signal intensity is reduced or destroyed when there is a leak or defect. These variations are meticulously monitored to identify defects. With airborne ultrasound technology, it’s now possible to identify a variety of seal defects, including visible and invisible, leaking and non-leaking, process-related and random both offline in the lab and in automated production environment.

Airborne Ultrasound technology has been proven in the field with both online (Seal-Sensor) and offline (Seal-Scan) solution options. Both of these technologies make use of non-contact airborne ultrasonic testing. It is known to be among the best techniques for non-destructive testing of flexible packaging seals in both offline laboratory testing for seal quality analysis and 100% inline testing on the production line. According to ASTM F3004-13, this is the standard test procedure for the airborne ultrasound evaluation of seal quality and integrity.

Benefits of Seal-Scan and Seal-Sensor Methods

  • Deterministic seal quality inspection method that produces quantitative outcomes.
  • Regardless of color, transparency, print, surface polish, or porosity, this method works for all material types and combinations.
  • Non-destructive and non-subjective test technique that does not require any sample preparation.
  • Technology may be used for 100% online final pouch seal defect detection.
  • Seal quality inspection results are repeatable, reproducible and reliable.
  • Cost-effective solution for testing seal integrity and seal analysis that characterizes the overall quality and uniformity of the seal.

According to studies, the conventional seal inspection techniques are ineffective because they miss undetectable flaws and wrongly reject pouches that are tightly sealed. Airborne Ultrasound is a deterministic seal quality testing method. The technology has established itself as a highly practical solution for non-destructive testing of porous packages. The integrity of porous packages can be tested efficiently using Airborne Ultrasound technology.

All About Airborne Ultrasound Technology

All About Airborne Ultrasound Technology

The integrity of container closure systems can be interpreted as their capacity to maintain a sterile barrier against potential contaminants that could compromise the quality of the end product. The sterile barrier can be damaged by even the smallest leak, which might affect the product's healing properties. Over the years, dye ingress and microbial ingress are common leak testing methods. It has been proven that they provide inaccurate and subjective results. As a result, regulatory organizations have mandated a shift towards more deterministic test procedures that can be controlled, calibrated, and provide a definite determination of CCI. Airborne Ultrasound technology is a deterministic test method mentioned in the revised USP< 1207> Chapter Guidance for seal quality testing.

Explain Airborne Ultrasound Technology

Airborne Ultrasound Technology is a technique for testing the seal quality. It is an ASTM test method F3004 and the Food and Drug Administration (FDA) approved standard for seal quality testing. Such inspections are mainly done to provide improved seal quality inspection of pouches, flexible packages and tray seals. Airborne Ultrasound technology ensures in-depth seal quality analysis and is applicable to multiple packaging materials such as Tyvek, paper, foil, film, aluminum, plastic and poly.

In this technique, sound waves are reflected when ultrasound waves travel through the packaging seal. In the presence of a leak or fault, the signal intensity is diminished or removed. To find the leak, these fluctuations are carefully monitored. More sound is reflected, and less sound is transferred through the seal as the acoustic difference between the medium increases (most evident at the transition from a gas to solid state). The inability to detect non-leak defects is a common challenge faced by most leak test methods. However, users may recognize a variety of seal defects, including visible and invisible, leaky and non-leaking, process-related and random, using airborne ultrasound technology.

Seal-Scan and Seal-Sensor

Under this technique, VeriPac leak testers are connected to a test chamber specially designed to hold the sample package. The package that has been put inside the test chamber is subjected to vacuum. A single or dual vacuum transducer technology is used to monitor the vacuum level as well as how the vacuum changes during a predefined test period. The existence of leaks and other defects within the package is determined by monitoring variations in an absolute and differential Seal-Scan® and Seal-Sensor™ are the two configurations of Airborne Ultrasound technology. Seal-Scan® technology inspects and analyzes pouch seals non-destructively offline. This deterministic, quantitative, high resolution method inspects pouch seals for defects and seal integrity for consistency. Testing does not involve sample preparation, and is non-invasive as well. The technique includes advanced digital imaging software tools for process control that allow in-depth seal quality analysis. Utilizing Airborne Ultrasound technology, Seal-Scan® systems evaluate seal quality and integrity in accordance with ASTM Test Method F3004-13. Seal-Scan® is a semi-automatic inspection system with an x-y drive for the detection of seal defects, seal characterization, and material analysis.

Seal-Sensor™ is an Airborne Ultrasonic technology that inspects the final pouch seal 100% online in a non-destructive manner. Seal-Sensor™ is a deterministic, quantitative, fast, and reliable way to test for defects in pouch seals. The Seal-Sensor™ technology detects defective seals, seals with partial or weak areas, and several other typical seal defects that may not be physically visible but have an impact on the quality, and life span of the product. A pass/fail result and quantitative, traceable data are generated by a single linear scan (L-Scan) of the pouch seal in less than one second.

Why Use Airborne Ultrasound Technology?

  • Deterministic inspection technique yielding quantifiable results.
  • Non-destructive, non-subjective, and does not need sample preparation.
  • Independent of color, transparency, print, surface polish, or porosity, it is applicable to all materials and combinations.
  • Can be integrated completely online to identify defects in the final pouch seal.
  • Consistent and dependable results.
  • Referenced in USP Chapter 1207.Inexpensive method for evaluating the seal integrity of the final pouch seal.

Techniques Involved in Leak Testing Vials

Techniques Involved in Leak Testing Vials

Pharmaceutical vials are small bottles or containers designed for parenteral administration (injection or infusion) in a single patient for a single case, procedure, or injection. They offer the highest Container Closure Integrity (CCI), which is a measure of how well a container protects the pharmaceutical ingredient against contamination by a variety of factors such as moisture, air, and chemicals.

In pharmaceutical manufacturing, the leak test is a critical parameter for vials. A visual inspection process may not detect defects that cause a sterile vial to leak. Thus, the pharma companies move toward CCI test methods. Many manufacturers are not sure how to conduct a container closure integrity test, but parenteral product leak testing is very important to assure that the product remains sterile in the packaging configuration throughout the duration of the product's shelf life.

What is CCIT?

Container Closure Integrity Testing (CCIT) is an important quality control technique for pharmaceuticals. It is an assay that evaluates the container closure and its capacity to keep possible contaminants out. Microorganisms, reactive gases, and other chemicals are examples of potential contaminants. This test is necessary for parenteral products since the seal quality is crucial to the drug product's sterility and quality throughout its shelf life. Inadequate sealing can accelerate the expiration of a drug product and cause significant risk to the patient's health if the product loses its sterility.

Previously, sterility testing was used to demonstrate container integrity. However, due to the insensitivity and other challenges associated with sterility tests, a variety of container closure integrity tests were developed. MicroCurrent HVLD, Vacuum Decay, and Helium Leak Detection are some of them. We give a brief overview of the above pharmaceutical package testing methods that can be used for testing pharmaceutical vials.

Leak Testing Vials Using Various CCI Techniques

  • MicroCurrent HVLD Technology

  • High Voltage Leak Detection (HVLD) is a non-destructive Container Closure Integrity technology that is used to evaluate the closure integrity of parenteral product packaging. HVLD technology makes use of quantitative electrical conductivity and resistance principles. The technology works by transmitting high voltage microcurrent impulses through sample packages. The electrical resistance of the sample lowers in the presence of a leak, resulting in an increase in current. HVLD technology relies on the “flow” of current, while other leak detection methods rely on the flow of gas or liquid. The MicroCurrent HVLD lowers product voltage exposure to less than 5% of that experienced while testing with similar HVLD technologies. When compared to conventional HVLD systems, reducing exposure voltage not only eliminates any risk that the voltage provides to the product, but also significantly reduces Ozone formation during operation. MicroCurrent HVLD can be used to test for leaks in nonporous, rigid or flexible packages, as well as packages containing liquid or semi-liquid products.

  • Helium Leak Testing

  • Helium leak testing is the method of locating leaks in enclosed or sealed systems by utilizing helium as a “tracer” gas and measuring the concentration as it exits owing to leakage. The package is filled with helium and vacuumed in this method. A helium leak detector is used to determine how much helium leaks from the container. The outcome is expressed as a leak rate. Helium leak testing is used in product design, product quality studies, failure analyses, and validation, in addition to being an effective container closure integrity test technique. Helium leak testing ensures high sensitivity leak detection, which is not achieved by many other leak test methods.

  • Vacuum Decay Technology

  • Vacuum Decay is a deterministic Container Closure Integrity testing methodology that relies on package integrity and leak path detection. Unlike human inspection and other non-deterministic testing techniques, Vacuum Decay provides quantitative and reliable test results to assure package integrity. Vacuum Decay technique can handle a wide range of package types, including filled and sealed rigid, semi-rigid, and flexible packaging comprised of nonporous or porous materials. This test involves placing packages in an evacuation test chamber with an external vacuum source. Vacuum levels are regularly monitored to detect deviations from a predetermined intended vacuum level. A defect in the packaging will allow air to escape into the test chamber. Packages with no defects, on the other hand, maintain a steady chamber vacuum level. Over the years, Vacuum Decay technology has proven to be one of the most practical and sensitive vacuum-based leak detection technologies.

Historically, dye immersion and microbiological immersion were the two most popular methods for leak testing vials. Recently, the USP has issued guidelines requiring the use of deterministic methods in order to produce more consistent and predictable results. USP<1207> recommends that dye immersion tests are avoided and HVLD or Vacuum Decay tests are used instead.

Integrity Testing of Vials with MicroCurrent HVLD Technology

Integrity Testing of Vials with MicroCurrent HVLD Technology

Several leak detection methods, that are deterministic and non-destructive, are already available in the market. Pharmaceutical companies are urged to use technologies that significantly enhances quality assurance and leak detection rates. Appropriate leak detection technology is selected based on the specific characteristics of the product and container, such as conductivity, headspace parameters, contents, or API. Historically, dye immersion and microbial immersion have been the two main methods of vial integrity testing. Recently, the USP has issued guidelines that require critical methods to achieve more reproducible and predictable outcomes. USP <1207> encourages a move towards more deterministic methods, recommending the avoidance of dye immersion tests and the use of quantitative, non-destructive technologies instead.

Why High Voltage Leak Detection Method is Preferred for Testing Vials?

High Voltage Leak Detection or HVLD is a deterministic, non-destructive leak detection method to evaluate vials, cartridges, and other liquid-filled parenteral products for Container Closure Integrity. The current generation of PTI’s MicroCurrent HVLD may be utilized with a wide range of liquid-based products, from low conductivity sterile water for injection to highly proteinaceous drug preparations in suspensions. It is one of the most effective online container closure testing methods, requiring just minor infrastructure modifications. When compared to conventional HVLD solutions, MicroCurrent HVLD utilizes approximately 50% less voltage and exposes the product and environment to less than 5% of the voltage. This method is non-invasive and requires no sample preparation. Like vial leak testing, another major application of MicroCurrent HVLD is pre-filled syringe testing.

Working Principle of MicroCurrent HVLD Technology

In this method, the container is scanned using a set of high voltage electrode probes. A high voltage is applied to one side of the container, while a ground probe is attached to the other. If there is no leak in the package, the two container walls (high voltage side and ground side) offer complete electrical resistance, and no substantial current is measured flowing through the vial. If a micro-leak or fracture occurs in one of the container walls, the break-down resistance is achieved, and the current flows through. HVLD is the only leak detection method that does not require mass to travel through a defect location, instead of requiring just electricity to pass through a crack. Because of this feature, HVLD is sensitive to leaks that conventional leak detection technologies are unable to detect.

MicroCurrent HVLD Technology Advantages

  • Deterministic and non-destructive test method.
  • High level of repeatability and accuracy.
  • Ensure more accuracy and dependability in results.
  • At high production rates, both offline and 100% online inspections are performed.
  • Simplifies the inspection and validation procedure.
  • Highly effective in all parenteral preparations, even liquids with extremely low conductivity (WFI).
  • Outlined in the USP 1207 Guideline.

Pharmaceutical containers like vials protect the product from contamination (sterile barrier) and prevent changes in product quality caused by external factors. In order to determine the functionality of such systems, container closure integrity testing is performed. CCIT provides sophisticated analytical methods for evaluating pharmaceutical containers.

Parenteral Products Package Testing with E-Scan HVLDmc

Parenteral Products Package Testing with E-Scan HVLDmc

For parenteral administration, compounded sterile preparations are often made from manufactured sterile materials. As a means of drug delivery, patients commonly require the administration of parenteral formulations. When compared to other methods of drug delivery, this method has both advantages and disadvantages. Nowadays, the ways of administration of new drugs are increasing all over the world. The range of possibilities for drug delivery containers must be reviewed on a regular basis, with the objective of improving compliance and delivery accuracy.

The packaging around a drug product is critical when establishing a new drug product or even re-facing an old one. There has also been an increase in the number of packaging formats for parenteral over the last ten years. Liquid-filled containers such as vials, ampoules, syringes, blow-fill seals, and auto-injectors, as well as containers filled with lyophilized products, are common parenteral packaging methods. Parenteral drugs are directly injected into the human body. Therefore, it is necessary to ensure the product quality of parenteral throughout its shelf life. Highly sensitive and reliable test methods are required. In this blog, we will discuss about parenteral product leak testing.

Why Use E-Scan HVLDmc for Testing Parenteral Products Packages?

E-Scan 655 is a revolutionary deterministic offline micro leak test equipment that inspects vials, syringes, and other liquid-filled parenteral products for container closure integrity using a new class of HVLD technology.

How VeriPac 355 Ensures Quality and Integrity of Pharmaceutical Packages?

How VeriPac 355 Ensures Quality and Integrity of Pharmaceutical Packages?

The pharmaceutical packaging industry is constantly developing as pharmaceutical manufacturers require reliable and efficient packaging solutions that meet a variety of requirements. Packaging is essential for the safe storage and administration of pharmaceutical products. Packaging pharmaceuticals is important not only for storing and protecting products but is also helpful in identifying, marketing, and promoting different brands, and making pharmaceutical products easier to use. Vials, blister packs, bottles, syringes, ampoules, etc are the most common pharmaceutical packages. The packages must perform correctly to ensure that the drug product remains uncompromised throughout the distribution cycle and shelf life.

Automation of Class III Medical Device Packaging

Automation of Class III Medical Device Packaging

Testing Container Closure Integrity (CCI) is crucial for ensuring the quality of Class III medical devices. Class III medical devices are sterile components that are designed to be inserted directly into the human body. These devices often sustain or support life, are implanted or pose an unreasonably high risk of disease or damage. A compromised package can serve as a vehicle for microbial transmission and compromised sterility, leaving patient safety at risk. When bacteria or other impurities enter the container, the device ceases to be a treatment and becomes a danger to the patient. Similarly, a breach of the seal affects the sterility of the device and may present a serious quality concern at a key point of usage.

Testing Challenges in the Medical Device Industry

There are three basic approaches to package integrity testing:

  • 100% in-line testing: All products in a batch are tested on a high-speed production line at an acceptable level of CCI assurance.
  • Small batch testing: Testing a statistically significant batch size for certain quality parameters and extrapolating to match the quality of the manufacturing lot.
  • Testing Offline: Operators test packages individually or in smaller batches.

Dye penetration is a technique for identifying defects in package body and seals that has a variable detection capacity. When carried out correctly, the approach can identify pinholes and channel defects as small as 20 microns. This method is only used to validate the packaging process and offers minimal value to in-process quality monitoring. The method is time-consuming to implement and provides limited information in the effort to ensure the quality of high-risk applications.

For CCI testing, the majority of medical device manufacturers use a 100% in-line manual visual inspection technique. Manual visual inspection has been proved to be one of the least reliable techniques for ensuring quality. The failure of manual visual inspection is caused by a number of factors. According to ASTM test method F1886, a manual visual inspection may detect 75-micron channel defects in a transparent seal 60-100% of the time. Although manual visual inspection can be applied as a 100% test method, performance on the task decreases significantly over time. This method is not applicable if the package format is not transparent or semi-transparent.

How Vacuum Decay and Airborne Ultrasound Technologies are Automated?

Vacuum Decay is a deterministic method proven to offer predictable and reliable results for CCI testing of high-risk package applications. This is an ideal solution for non-porous medical device applications. When the major focus of the inspection is the final seal of a porous package, Airborne Ultrasound is exceptionally efficient and reliable at detecting seal defects that are invisible to the manual visual inspector. Both approaches have shown to be reliable non-destructive testing methodologies, and one or the other can be used for inspection based on the unique features of the product and container.

The automation of each technology looks a little different. Vacuum Decay enables approximately 25 to 50 samples per minute, with low throughput detecting single-digit micron leak sizes. Airborne Ultrasound is a rapid-fire sensor that transmits 1000 pulses per second of sound through the seal. The final seal of Tyvek® pouches and other flexible packaging systems may be scanned at a rate of 20 inches per second (~40 cm/sec), with the capacity to detect the most frequent seal faults and seal quality concerns. Both methods enable a production line to ensure quality while reducing production throughput.

The Airborne Ultrasound technology offered by PTI can be automated in many ways. Basically, the technology can measure the quality of a quantitative seal in any way that the pouch seal can pass through the ultrasound inspection head. Ultrasound can be applied to the production flow, which captures seal quality when exiting a band-sealer or transferring pouches through a production line. Robotic handling may also be used to do a full 360-degree seal inspection on all pouch seals. Airborne Ultrasound has the flexibility to be deployed in a variety of production lines and has high reliability in detecting critical defects.

Vacuum decay is often utilized for both Tyvek® trays and non-porous container types. While a vacuum takes longer to do a test (about 5 seconds on a Tyvek tray), the sensitivity and stability of this technology make it perfect for low output applications with high sensitivity requirements. Robotic handling solutions can serve many test stations at the same time, allowing for increased product throughput without losing sensitivity.

Medical devices are packaged and delivered in a variety of ways, ranging from porous flexible packaging to non-porous rigid containers. The range of product types and packaging options create unique inspection challenges that must be overcome in order to assure seal strength, sterility, and quality. Airborne Ultrasound and Vacuum Decay offer 100% testing capabilities as well as an accurate inspection that includes quantitative test results and a pass/fail result. These new automated technologies, with more sensitive leak detection capabilities, inspect containers at a higher rate.

Understanding CCIT's Seal-Scan Technology

Understanding CCIT's Seal-Scan Technology

Package integrity leak test methods offered by CCIT such as Seal-Scan utilize non-contact Airborne Ultrasonic technology for seal integrity testing and seal quality analysis of pouches and flexible packaging. The method is applicable to pharmaceutical as well as medical device packaging.

Seal Quality Testing and Seal Analysis using Seal-Scan Technology

Seal-Scan® is a non-destructive offline inspection and analysis technique for pouch seals using Airborne Ultrasonic technology (ABUS). Seal-Scan® offers advanced digital imaging software tools for process control, including in-depth seal quality inspection. Seal-Scan system uses the non-destructive ASTM Test Method F3004-13 for "Evaluation of Seal Quality and Integrity Using Airborne Ultrasound Technology." This test method was approved using PTI's ABUS technology. Seal-Scan® is a deterministic, quantitative, high-resolution technology for inspecting pouch seals for defects and ensuring seal integrity.

Seal-Scan has two scanning modes:

  • Linear Scan (L-Scan) to simulate online defect identification (line graph)
  • C-Scan for detailed seal analysis, resulting in pixel-by-pixel seal evaluation (Opto-Acoustic image)

Technology Overview

The pouch seal or packaging material is scanned between two focused ultrasonic sensors. Ultrasonic waves travel through single or several layers of bonded materials. The reflection of sound waves caused by ultrasonic transmission via different materials reduces/eliminates signal intensity. The signal level that passes through the seal is a function of the seal's quality. Defects of various forms, such as leaking and non-leaking, process-related and random, can be detected. Seal-Scan® can provide Opto-Acoustic images as well as thorough statistical analysis using one of two scan modes (L-Scan and C-Scan).

An L-Scan is a single linear scan along the seal's X-axis that generates a line graph of seal integrity and replicates real-time inspection. C-Scan generates a series of scans (along the X and Y-axis of the seal region), that offers a high-resolution ultrasonic image of the seal structure. This technology, via the Seal-Sensor, can be integrated into a pouch production process for 100% online seal defect detection.

Benefits of Seal-Scan Technology

  • Deterministic inspection approach yielding quantitative results.
  • Works with any material and combination, independent of color, transparency, print, surface polish, or porosity.
  • Produces a high-resolution Opto-Acoustic seal image.
  • Characterizes the overall quality and consistency of the seal.

Seal-Scan® is a semi-automatic inspection system with an x-y drive that is used to identify seal defects, characterize seals, and analyze materials. This approach is non-invasive, non-destructive, and does not need any sample preparation. The ability of PTI to adapt this technology to diverse production restrictions and conditions makes it an effective solution for flexible packaging systems.

Development and Validation of CCI Testing Method for Pre-filled Syringes

Development and Validation of CCI Testing Method for Pre-filled Syringes

Pre-filled syringes are becoming more popular as a preferred container closure system for biologics. Pre-filled syringes must offer an inherent barrier that maintains drug product stability and sterility throughout its entire shelf life as a primary container closure system. The ability of the system to retain its microbial barrier integrity must be checked and demonstrated by the drug manufacturers. In 2008, the FDA endorsed CCI testing as part of the sterile product stability protocol.

The pharmaceutical industry has witnessed substantial technical developments in CCI testing in response to rising regulatory demands. MicroCurrent HVLD, Vacuum Decay Leak Testing and Helium Leak Detection are examples of new technologies that have proven enhanced detection capabilities above traditional Dye and Microbial Ingress approaches. Many of the technologies have been employed for CCI testing of drug product stability.

CCI Testing Strategy for Development

Many CCI failure modes can occur throughout the life cycle of a syringe, from component production to drug product filling and sealing, device assembly and packaging, and finally distribution and storage. It is critical to create a comprehensive plan for conducting CCI testing across the whole syringe life cycle.

The creation of the CCI testing technique begins with a detailed study of the construction, design, and manufacturing procedures used in syringes. The failure modes and impacts associated with each aspect of CCI were identified first. The next step was to evaluate whether CCI testing is required, as well as the intended uses and testing frequencies, using a risk-based approach. Knowing that the needle shield compartment seal integrity had been verified by the component supplier, apply a non-routine CCI test to validate its seal integrity during drug product loading and sealing, as well as during device assembly. To ensure CCI was achieved and successfully maintained, implement a complete set of CCI tests across the entire product development cycle for the product-containing syringe barrel compartment.

Method Development and Method Validation

Method development consists of optimizing testing parameters and determining the appropriate pass/fail threshold.

  • Testing parameters optimization
  • Initially, several defect standards of known sizes were examined alongside undamaged samples using varied testing conditions. The relationships between key method parameters and instrument responses to intact and defect samples were comprehensively investigated, with the objective of determining a set of variables that give optimal separation between intact and defect samples. i.e. signal-to-noise ratio or SNR.

  • Pass/fail threshold determination
  • The improved method was utilized to evaluate different lots of filled intact syringes representing relevant product variations, such as drug product batches, and packaging locations and lines, in order to define the preliminary pass/fail threshold. For intact samples, the results of the tests were statistically assessed to determine the instrument baseline and variation (σ). Typically, the pass/fail threshold should be 10 σ higher than baseline. The pass/fail threshold was then further refined and verified by testing defect standards of known sizes.

CCI testing techniques were validated for the pharmaceutical product package. Since the drug product formulation and package design may change during the early development stages, a step-by-step approach was adopted to validate the methods in line with the product development stages. Once product design and packaging design are complete, the methods are fully validated to support CCI testing for initial consistency and process evaluation. The power of the additional long-term method may be further validated before this method is implemented in QC laboratories for routine testing.

During package and pharmaceutical product development and manufacturing, properly selected and verified methodologies are critical for demonstrating container closure integrity. It should be noted that existing CCI testing methods do not provide an optimal solution for all pre-filled syringe CCI testing requirements. To maintain total container closure integrity, an integrated solution involving CCI testing as well as additional engineering and administrative controls is required.

A Quick Rundown on Package Inspection Guidelines for Sterile Medical Products

A Quick Rundown on Package Inspection Guidelines for Sterile Medical Products

Class III medical devices have a unique combination of criteria and package features that necessitate a comprehensive approach to determining the best inspection procedures. For medical package inspection, there are a variety of methods that require a thorough understanding to assure quality.

Manual visual inspection has been the most common form of inspection for medical device packaging. While an ASTM standard (ASTM F1886) covers this concept, it may not be applicable for all applications and has limitations. Even though a 75-micron channel defect can be detected by manual visual inspection, the ASTM method F1886 indicates that the chance of detection ranges from 60% to 100%. This vast range of uncertainty does not give the level of assurance required for the packaging of high-risk medical devices.

Although certain offline leak detection techniques can offer a quantitative evaluation of seal quality, they miss some of the most prevalent seal problems seen in Class III medical device packaging. Testing peel strength or utilizing other destructive methods will not reveal random seal problems. For class III medical devices, online non-destructive inspection procedures are excellent since they provide quality control with comprehensive manufacturing lot data.

All Class III medical devices must be sterile, however, container materials and design differ widely. A non-porous pouch or tray demands an entirely different technique than a porous pouch or tray. Tyvek® offers a sterile barrier, and the porosity of the material limits the leak test procedures that may be used on the package body. When it comes to porous packaging, the focus of online inspection moves away from leak detection and toward seal quality evaluation.

Technology Overview

Vacuum decay and Airborne ultrasound are the two main methods used by PTI/CCIT to inspect medical device packaging. Both methods are aimed at providing quantitative and deterministic test results in order to assess package quality. In terms of function and performance, the two technologies are entirely different. Package integrity and leak path detection are the main objectives of Vacuum decay. Meanwhile, Airborne ultrasound technology focuses on package seal inspection and seal quality. Both approaches aim to meet the basic requirements of being reliable and sensitive inspection procedures for Class III medical device applications.

Vacuum Decay (ASTM F2338)

Vacuum decay is the most practical and sensitive vacuum-based leak test method of CCI. When testing pouches, a versatile adjustable test chamber may be utilized to test pouches of various sizes. The package is then placed into the vacuum-sealed test chamber. The level of vacuum, as well as the change in vacuum during a pre-defined test duration, are both monitored during the short test cycle. The change in vacuum indicates the existence of leaks and defects within the package. Vacuum decay leak testing is a go-to standard for sterile products because of its sensitivity and dependability. The approach is ideal for laboratory offline testing and production applications for quality assurance process control, since test equipment may be developed for manual or automation operation.

The ASTM Vacuum decay leak test technique (F2338), which has been accepted by the FDA as a consensus standard for package integrity testing, was developed using PTI VeriPac technology. As a deterministic test technique for package integrity test solutions, Vacuum decay is mentioned in ISO 11607 and the new USP 1207 guideline document.

Airborne Ultrasound (ASTM F3004)

Airborne Ultrasound is an ASTM Test Method F3004-13 and is one of the most effective methods for non-destructive seal quality inspection of flexible packaging. It is mentioned in ISO 11607 and the new USP 1207 guidance document. Most inspection methods are challenged by the leaking nature of porous packaging, but Airborne ultrasound, with its non-destructive measure of seal quality, effectively overcomes those challenges.

The non-contact Airborne ultrasonic testing technique is used in both Seal-Scan (Offline) and Seal-Sensor (Online). Ultrasonic waves propagate through the material as a package seal passes through the sensor head, producing sound waves to be reflected. When defects are encountered, the signal intensity is reduced or eliminated. The larger the acoustic gap between mediums, the more sound is reflected and less sound is transferred through the seal.

The variety of package forms and materials makes inspecting the integrity of class III medical device packaging a challenge. CCIT's scientists and engineers have vast industry experience and can prove a complete solution, including test method development and equipment validation for Class III medical device packaging.

MicroCurrent HVLD for Testing the Integrity of Ampoules

Pharmaceutical package integrity testing has always been an important aspect of the quality control and manufacturing process. Container Closure Integrity is critical for protecting the product throughout its lifespan until it is delivered to the patient. CCIT uses non-destructive inspection technologies for ensuring container closure integrity of vials, ampoules, syringes, cartridges, and auto-injectors.

Ampoules must be properly sealed since any crack or defect might contaminate the sterile substance inside. Microbial contamination, exposure to gases, water vapor, and solvent loss can all cause product degradation if there is any breach in the package. Hence, container closure integrity is an essential stage in the lifecycle of a sterile pharmaceutical product. Patients may be at risk if the container closure integrity is compromised. Drugs that are meant to save lives might lose their effectiveness or cause fatal side effects. CCI defects can cause oxidation, which can reduce a drug's potency and shelf life.

Integrity Testing of Ampoules using MicroCurrent HVLD

MicroCurrent HVLD technology detects leaks in nonporous, rigid, or flexible packaging such as ampoules that contains liquid products. This is a non-destructive High Voltage Leak Detection Technology that is highly effective across all parenteral products (vials, syringes, ampoules and BFS). The test technique detects pinholes, microcracks, stopper/plunger leaks, non-visible leaks under crimping, and many other defects by scanning a non-conductive container sealed with electrode probes. Any crack or other defect in the container can cause a resistance difference and a change in the current flow, which would indicate a breach. It is also possible to determine the approximate position of the defect.

When compared to conventional HVLD technologies, MicroCurrent HVLD uses around 50% less voltage and exposes the product and environment to less than 5% of the voltage. At high production speeds, this HVLD method may be simply transitioned from offline to 100 percent inline testing applications. It is a cost-effective online container closure testing solution that requires only minor infrastructure changes. This method is non-invasive and does not need sample preparation.

Evaluating Package Integrity Solutions for Vials

Evaluating Package Integrity Solutions for Vials

Sterile pharmaceutical products including vials are manufactured with extreme accuracy and zero tolerance for error. As a result, pharmaceutical manufacturers place a high value on their quality control procedures. This is to guarantee that the items meet the quality requirements for their intended application. Packaging is essential for maintaining product quality and providing protection from harmful external forces. Package integrity testing, in addition to selecting suitable packing material, is a crucial component in preserving product quality. It prevents external contamination that can have a negative influence on drug quality by ensuring that there are no leaks within the package.

An effective package integrity solution for vials will ensure:

  • The vial is well-protected from external factors that might affect its quality, such as light, oxygen, moisture, and temperature
  • It is safe from contamination

Various Container closure integrity testing (CCIT) technologies are available today. Helium leak detection is one of the leading methods used for testing the container closure integrity of vials.

Helium Leak Detection Technology for CCI testing of Vials

The process of detecting leaks in various enclosed or sealed systems by utilizing helium as a tracer gas and measuring its concentration as it leaves due to leakage is termed Helium leak testing. Simply say, a vial that consists of a container and an elastomeric closure is a good example for package system. The vial is filled with helium and evacuated. The quantity of helium that escapes from the package is quantified and expressed as a leak rate. A prefilled syringe, a foil pouch, or a cold form blister card are another example. Each of these package types is meant to keep the pharmaceutical product enclosed while keeping out potentially harmful environmental pollutants like germs, or even gases.

Helium gas has a number of qualities that make it the best choice for package leak testing

  • As helium gas is one of the smallest molecules, it may reliably and rapidly breach pathways.
  • It is an inert gas that won't react with the components being tested, therefore it's perfectly safe to use.
  • Because of its limited presence in the atmosphere (less than 5ppm), instrument noise from atmospheric helium is intrinsically minimal, resulting in very precise findings.

Following are the advantages of using helium leak detection technology for CCI testing

  • Highly sensitive leak test method for CCI
  • Specially designed for detecting extremely small leaks that other leak test methods failed to detect.
  • The leak test thresholds might be adjusted as low as 1 x 10 -10 cc/s using a high vacuum technique. This allows unique comparison amongst package components.

Sterility of vials is essential for reducing and preventing infection in patients when using the medicine. As a result, package integrity testing is essential for regulatory approval of sterile pharmaceutical products, and medical devices. When it comes to package integrity testing of vials, the terms packaging integrity and container-closure integrity are sometimes used interchangeably.

At CCIT, we provide a wide range of quality leak testing equipment for pharmaceuticals including vials. With our high-grade non-destructive testing equipment, you can ensure that your products meet stringent quality requirements.

Pre-filled Syringes Leak Detection with Vacuum Decay Vs MicroCurrent HVLD Test Methods

Pre-filled Syringes Leak Detection with Vacuum Decay Vs MicroCurrent HVLD Test Methods

Pre-filled syringes have a significant role in the injectable drugs market. Because of its convenience, efficiency, and patient safety, pre-filled syringes are now widely utilized in a variety of medical areas. Pre-filled syringes, which are rapidly replacing traditional syringes are frequently used to deliver vaccinations. Defects in pre-filled syringes are mostly determined by pharmaceutical product design and syringe process design. Patient-related concerns are also a regulatory concern. As a result, it is critical for manufacturers to have a thorough understanding of the various tests involved in order to assure patient safety.

Evaluating leak test using Vacuum Decay Vs MicroCurrent HVLD Test Methods

Manufacturers perform Container Closure Integrity testing to ensure that the product maintains sterility and microbiological quality until the point of use. Container closure integrity testing evaluates a container closure system's capacity to maintain a sterile barrier against contaminants that might affect the quality of the resulting pharmaceutical and biological products. Various test techniques may be used to challenge Container Closure Integrity (CCI), however, not all of them are equally capable of finding package leaks. Vacuum Decay and High Voltage Leak Detection (HVLD) are the two deterministic test techniques for CCI mentioned in USP 1207, that are frequently used for parenteral products.

Technologies Overview

Vacuum decay leak testing is a CCI test method that has been proven over decades and improved with new technology innovations. When compared to destructive testing techniques, non-destructive testing not only provides for a better knowledge of package quality but also minimizes waste. As a result of the waste reduction, the return on investment will be higher.

Vacuum Decay method operates by enclosing sample packages in a tight-fitting evacuation test chamber with an external vacuum source. The test chamber is monitored for both the level of vacuum and the change in vacuum during a set test duration using either single or dual vacuum transducer technology. The existence of leaks or flaws within the package is indicated by variations in an absolute and differential vacuum. The Vacuum Decay method for leak detection of pre-filled syringes have proven to be an effective method of testing.

Benefits of Vacuum Decay

  • ASTM Test Method F2338 and referenced in USP 1207 Guidelines
  • Deterministic, quantitative test method
  • Repeatable, rapid, and reliable testing
  • Non-destructive technology
  • Completely tool-less with no changeover to test different packaging formats

High Voltage Leak Detection (HVLD) is a deterministic CCI test method for package inspection of non-porous pharmaceutical and parenteral goods. This technique is based on the fundamental characteristic of electricity. MicroCurrent HVLD technique, the latest evolution of HVLD developed by PTI, promises to provide a high degree of CCI assurance throughout the whole range of parenteral goods.

This method operates by scanning the container which can be done offline in the laboratory or online in an automated robotic platform. On one side of the container, a high voltage is supplied, while the other side has a ground probe. If there is no leak in the package, the two container walls (high voltage and ground) offer complete electrical resistance, and no substantial current is measured passing through the vial. The break-down resistance is achieved when there is a micro-leak or fracture in one of the container walls, and the current passes through. HVLD is the only leak detection technique that does not require mass to flow through a defect location, instead of relying on electricity to pass through a crack.

Benefits of MicroCurrent HVLD

  • Non-destructive technology
  • Non-invasive, no sample preparation
  • High level of repeatability and accuracy
  • Offline and 100% online inspection at high production speeds
  • Low voltage exposure to product and environment

Pre-filled syringes have emerged as a practical and dependable source for unit dosage medication as the pharmaceutical industry continues to seek possibilities to create convenient drug delivery techniques. We, at CCIT put a lot of effort into developing customized handling solutions that guarantee that syringes are moved without touching their piston to minimize product loss.

Importance of Testing and Inspection of Pharmaceutical Products

Importance of Testing and Inspection of Pharmaceutical Products

Prior to commercialization, the development of new pharmaceuticals, particularly combination treatments, was a complicated process involving extensive research. When it comes to packing pharmaceuticals for patient use, several things must be considered to ensure that they satisfy the highest quality requirements and are safe to use.

Nowadays, the challenge of adopting traditional glass or specialized polymers as combination products has become common. Similarly, the demand for scientific evidence to support regulatory requirements for the pharmaceutical industry has also become more prevalent. For effective development and commercialization of a pharmaceutical product, it is important to understand the compatibility and performance of the primary packaging system with both, the pharmaceutical product and the delivery systems, regardless of the material.

Container Closure Integrity (CCI)

Container closure integrity (CCI) testing is important when ensuring the quality of all packaged products, especially when it comes to parenteral drugs. To evaluate the CCI of the packaging system, a pharmaceutical manufacturer must calculate the Maximum Allowable Leakage Limit (MALL) for the pharmaceutical product. MALL is defined by USP<1207> Package Integrity Evaluation – Sterile Products as the highest leak rate that may be tolerated for a specific packaging method while posing no harm to the safety and quality of the pharmaceutical product over its shelf life. In comparison to probabilistic approaches, USP <1207> provides guidelines on how to assess CCI, including deterministic methods, which are strongly encouraged. Helium leak detection, MicroCurrent HVLD, and Vacuum decay- are deterministic techniques. For the given system, these techniques must be created and validated.

Test methods

MicroCurrent HVLD

MicroCurrent HVLD is a non-destructive technique for determining the integrity of container closures for a variety of parenteral liquid products, including ultra-low conductivity sterile water for injection (WFI). A non-conductive container is examined for pinholes, micro-cracks, plunger leakage, and non-visible crimping leaks, among other things, using an electrode probe. Whenever a defect is identified, it causes a change in current flow and resistance differential, which indicates a breach in the container. The MicroCurrent HVLD is a High Voltage Leak Detection method effective across all parenteral products.

Helium Leak Detection

Helium leak detection is a deterministic method used to detect leaks in pressure vessels and other enclosed systems. In this technique, helium is used as a tracer gas. The change in helium concentration as it escapes through the container is monitored. For helium-based leak detection systems, the Seal Integrity Monitoring System (SIMS) 1915+ is a perfect choice. Helium as a tracer gas delivers excellent levels of quantitative accuracy when compared to traditional vacuum bubble and dye penetration test techniques. Helium is an optimal solution for product quality monitoring across the product lifecycle.

Vacuum Decay

A non-destructive CCI test method for evaluating medical device package integrity. Non-destructive testing improves package quality while decreasing waste when compared to destructive testing. This testing also saves time and money while ensuring product quality. This method operates by enclosing sample packages in a tight-fitting evacuation test chamber with an external vacuum source. A single or dual vacuum transducer is utilized in the test chamber to measure the level of vacuum as well as the change in vacuum over a pre-defined time period. The existence of leaks and defects is indicated by fluctuations in the package's absolute and differential vacuum.

Regardless of the pharmaceutical product, type of materials, devices used, developing a complete testing plan from initial compatibility to stability and release is critical. To assure the availability of scientific data that helps ensure optimal results for patients as well as rapid regulatory approval and delivery to the market, proper testing is required.

How Automated CCI Testing Reduces Pharmaceutical Package Integrity Issues

How Automated CCI Testing Reduces Pharmaceutical Package Integrity Issues

Container Closure Integrity (CCI) is primarily intended to ensure parenteral bio-pharmaceutical sterility and product quality throughout its shelf-life and usage. Guidelines for initial qualification and standards for validation have been set out and are available in chapter 1207 of the US Pharmacopeia (USP<1207>) (1). Any common CCI testing (CCIT) approach can be used to obtain a method that is suitable for its intended application within an end-use cycle. the principles outlined in USAP<1207>. CCI is an integrative and comprehensive process.

Common challenges faced by the pharmaceutical packaging

Pharmaceutical packaging plays a very important role in ensuring protection and maintaining the quality of pharmaceutical products. As a result, a great number of challenges are faced by pharmaceutical packaging. Let us see some of the challenges.

1. Preserving the medical quality of products

The medicines may lose their therapeutic properties, which is one of the biggest challenges faced by the industry, owing to a continuous exposure to heat and moisture. Pharmaceutical materials must be carefully selected and must not be allowed to alter the product by external elements or the product may become totally waste.

2. Ensuring safe transportation of liquid medications and injections

The other big challenge faced by pharmaceutical packing involves ensuring the safe shipping of non-solid medications such as liquids medications and injections. Due to it’s fluid nature, these non-solid medications are considerably harder to handle, especially with glass packaging. There is a high chance of breaking down. In order to avoid this problem, modern technologies like foam packaging and roto molding cases are integrated into the pharmaceutical packaging industry so that the glass packaging does not break down.

3. Proper information of medicine and dosage

The specified dose consumption of medicine is very much important. Also the package must provide information on the required dose, and information about the medicine it is composed of, expiry date and the serial number in order to avoid any misunderstanding.

Role of CCI testing in reducing pharmaceutical package problems

CCI testing helps mitigate pharmaceutical package issues to a great extent. The capacity to describe elements and chemicals which are able to move through container closure system components and contaminate the therapeutic product is a crucial stage in knowing the biological safety and appropriateness of a container. The US Pharmacopeia (USP) and Food and Drug Administration (FDA) are the main forces behind the safety assessment of materials and container closure systems in the United States. These are complying with high Container Closure Integrity Testing criteria (CCIT).

Many damaging procedures were considered suitable to guarantee that container closures preserve the sterility of devices. Basically blue dye or water bath are the procedures. These procedures were actually time consuming, inaccurate and unreliable. Moreover, test operators may not be able to control some test aspects and the resultant findings may be subjective. As a result, the FDA led the industry to shift away from the probabilistic test techniques in favor of deterministic technologies that make it possible for variables to be checked better, performed in consistent circumstances and reliably detect major leakages. Until the emergence of new technologies such as Vacuum Decay and MicroCurrent HVLD, a proper balance between sensitivity and reliability was a difficult factor. These new technologies can successfully scan containers with a greater sensitive leak detection capacity at a much faster speed than ever before.

Vacuum Decay technology: A non-destructive Container Closure Integrity(CCI) testing method which measures leak by vacuum decay. This technology is usually used for sealed packages. In nonporous, stiff or flexible packaging the vacuum decay test identifies leaks. The vacuum decay leak test method is used to check the packages after they are filled to verify the integrity of the product. This method is mainly used by the food package manufacturer, beverages and pharmaceutical industries. This approach minimizes the number of precious completed medicines needed to evaluate stability because the test is not destructive of the samples. After the vacuum decay test, the same samples may be utilized for additional laboratory tests normally necessary for stability studies.

MicroCurrent HVLD technology: MicroCurrent HVLD is a non-invasive Container Closure Integrity(CCI) technology applicable for a broad variety of parenteral filled liquid goods, including exceptionally injecting low conductivity sterile water and protein-filled products. The test procedure assures CCI by scanning a container that is non-conductive and sealed with electrode samples to identify pinholes, micro cracks, leakage of stoppers/plungers, invisible leaks, etc. The resultant difference of resistance and change in current flow indicates a breakdown in the container. Thus a defect is detected with exact defect location.

In addition to offline laboratory systems for leak detection and package quality testing, CCIT offers configurations that provide the capability of fully automated inspection. These technologies do not compromise the reliability of test measurement and automatic inspections take the perfect time to manage and monitor expensive final goods. Automated inspection platform provides best in class CCI testing with no compromise within the parenteral process. PTI’s technologies provide the reliability and accuracy in test measurement, while the automation platform provides the flexibility needed to not compromise on quality.

Commonly made of thermoformed plastic, these are quite useful in guarding products against external factors like heat, moisture and humidity.

However, concerns over integrity of blister packaging have increased over the years. Even a minute breach in the packaging can result in compromised package integrity. Hence, pharmaceutical manufacturers concerned about quality and shelf life of their products make Container Closure Integrity testing a crucial part of their manufacturing process. There are several methods available to test blister packs, and each has its own merits and demerits. For instance, the most common method to test blister packs remain dye ingress. However, this method is subjective, probabilistic and lacked accuracy in test results. This encouraged manufacturers to use non-destructive CCI test methods, that were accurate and produced quantitative results with measurable result data.

Blister Package Inspection with VeriPac UBV Technology

The VeriPac UBV Leak Detection System is a deterministic, non-destructive technology designed specifically for multi-cavity blister packs. The VeriPac UBV utilizes volumetric imaging under vacuum to detect the presence and location of leaks. It is a rapid test requiring no changeover or sample preparation. Operators simply input the number of blister cavities, place the blister pack on the inspection plate and press the START button. Within seconds, the operator sees a definitive pass/fail result, along with a volumetric measurement reading. The location of the defective cavity is presented to the operator with an image of the tested package. The intuitive and simple method makes it a practical solution giving rapid feedback to production line operators.

The UBV technology can provide rapid detection of defects as small as 10 microns with a fast test time, averaging 10-30 seconds depending on blister cavity volume. Test system requires no tools or test parameter changes for different blister formats. This technology is particularly advantageous for small to tiny blister cavities that are notoriously difficult to detect with a standard Vacuum Decay technology due to the very low headspace.

Technology Overview

Under this method, the sample is first placed inside the hinged test chamber. After pressing the start button, vacuum is pulled to a defined level. The blisters expand under vacuum, driving air out of the blister through any leaks present. If there is a leak in the blister, the air escapes into the chamber leaving a collapsed blister package. During the dynamic vacuum test sequence, a volumetric measurement reading is taken which determines which blister cavities are defective.

Benefits of VeriPac UBV Technology

  • Non-destructive technology
  • Accurate and repeatable results
  • Pass/fail results backed by quantitative test data
  • Completely tool-less
  • No changeover to test different blister formats
  • Identifies which cavity is defective
  • Eliminates destructive, subjective testing methods

Airborne Ultrasound Technology for Efficient Medical Device Package Inspection

Airborne Ultrasound Technology for Efficient Medical Device Package Inspection

Medical device quality control inspection is considered to be highly significant in ensuring safe delivery of medical devices from their place of origin to the market. However, tremendous development in medical technologies have challenged the medical device packaging industry to ensure quality and reliability in packaging

Adding to that, drug contamination is a serious concern in any medical industry- specifically for Class III medical devices. Class III medical devices are understood as devices that sustain or support life and are implanted, or present potential unreasonable risk of illness or injury. Since these devices are directly placed into human bodies, proper packaging is required to ensure quality of the product until it reaches the patient. Any breach in the packaging can cause contaminants to enter the device, causing major health risks. Hence, appropriate package integrity testing and seal quality inspection of Class III medical devices are required so as to ensure seal quality and sterile barrier integrity are maintained.

Initially, manufacturers heavily relied on visual inspection or other probabilistic test methods to inspect seal quality and integrity. However, such methods lacked accuracy and reliability in terms of test results. Hence, manufacturers are now shifting towards non-destructive method for evaluating seal quality and inspecting physical properties of a seal. One such technique that is increasingly becoming popular among medical device manufacturers is Airborne Ultrasound technology. It is an ASTM test method F3004 and FDA recognized standard for seal quality integrity testing. These tests are primarily conducted to provide advanced seal quality inspection of pouches, flexible packages and tray seals. The test is conducted by transmitting high frequency sound waves through the pouch seal area, providing a simple pass or fail result of seal quality. A linear scan analysis of the seal area will detect channel defects, misaligned seals, incomplete and missing seals immediately after the package has been sealed. If the system detects a package defect, the product can immediately be removed from the packaging and reworked. Process related defects can also be addressed and corrected immediately, which significantly reduces the quantity of defective packages produced

Airborne Ultrasound technology variants, namely Seal-Scan® and Seal-Sensor provide both, offline and online inspection of packages and accommodate various package specifications, test sensitivity and package handling requirements. Seal-Scan® offline systems offer in-depth seal quality analysis and seal characterization. Seal-Sensor online inspection systems for automated 100% inline scanning of pouch seals can be integrated into pouch production or pouch handling line. They provide a quick analysis of the seal area without tampering with the packaging to identify defects, such as incomplete or missing seals, wrinkles, channel defects and so on.

Advantages of Seal Scan and Seal Sensor method

  • Deterministic seal quality inspection method that produces quantitative results.
  • This method works for any material type and combinations regardless of color, transparency, print, surface finish or porosity.
  • Non-destructive and non-subjective test method that requires no sample preparation.
  • Technology can be integrated for 100% online defect detection of the final pouch seal.
  • Repeatable, reproducible and reliable results for seal quality inspection.
  • Cost-effective solution for seal integrity testing and seal analysis that characterizes overall quality and uniformity of the seal.
