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.

VeriPac 310 Package Integrity Solution for Food Package Industry

VeriPac 310 Package Integrity Solution for Food Package Industry

Packaging has a significant impact on the quality of the products and influences customer purchase decisions. Both of these factors provide significant issues for product design, particularly in the case of food packaging. No other product incorporates as many innovative and improved packaging advancements as food. Due to the increased need for convenience, packaging should be easy to handle, easy to open, resealable, or must be able to be heated directly in a microwave. Furthermore, food packaging must be properly sealed to protect product quality and shelf life. Ensuring safe food packaging through testing and analysis is key to safeguarding human health and protecting the food product.

Food Package Integrity Testing Using VeriPac 310

The VeriPac 310 is a non-destructive, non-invasive leak detection and container closure integrity testing method for the food industry. VeriPac systems eliminate waste and provide operators with a comprehensive view of package quality. The VeriPac 310 test cycle generates real-time results from accurate quantitative measurements, identifying packaging defects before important process concerns develop. Tests can be run in any order and even on the same sample several times. Good packages can be returned to the packing line intact. Testing is more dependable, sensitive, and efficient than destructive procedures like the water bath or burst test. The ASTM-approved patented vacuum decay leak test technique F2338-09, acknowledged by the FDA as a consensus standard for package integrity testing, is used in the VeriPac 310.

Technology Overview

The test method begins by connecting the VeriPac leak testers to a test chamber that is specifically designed to accommodate the package to be evaluated. The package is placed into the vacuum-sealed test chamber. The absolute transducer technology is used to monitor the vacuum level as well as the change in vacuum throughout a predetermined test period in the test chamber. The presence of leaks within the package is indicated by the changes in an absolute and differential vacuum. Test systems can be configured to operate manually or automatically. This inspection method is appropriate for offline laboratory testing as well as production applications for QA/QC statistical process control. The test cycle is non-invasive and non-destructive to both the product and the package, taking only a few seconds.

VeriPac 310 Benefits

  • Non-invasive inspection system for leak detection
  • Deterministic, quantitative test method
  • Non-destructive, non-subjective, no sample preparation
  • ASTM test method and FDA recognized standard
  • Cost-effective and economical
  • Supports zero waste initiatives
  • Measures integrity of the entire package

Every packaged food product has a seal that keeps the food item safe inside the packaging. Therefore, food package seal quality testing is performed to ensure that the food packaging used is safe for both customers and the environment. PTI offers a diverse range of testing methods that are applicable to food product packages.
