Industrial Applications of Vacuum Decay Technology

Industrial 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.
