Testing Integrity in Radioactive Pharmaceuticals Using Vacuum Decay Technology

Vacuum Decay leak testing is a non-destructive Container Closure Integrity Test (CCIT) method commonly used to detect leaks in sealed packaging. Known for its sensitivity and practicality, it can identify leaks in rigid, semi-rigid, or flexible packages, whether made from porous or non-porous materials. This method offers reliable, accurate, and consistent results, ensuring precise package integrity testing. As a non-destructive alternative to traditional water bath and dye ingress tests, vacuum decay provides an effective solution for leak detection in the pharmaceutical and medical device sectors.

Vacuum Decay operates on fundamental physical principles of container integrity. The package is placed inside a sealed vacuum chamber connected to an external vacuum source. A specific vacuum level is applied based on the packaging type and required sensitivity. The system then monitors the chamber and any dead space for a set duration. Sensitive differential pressure transducers track changes in vacuum levels over time. A pressure increase beyond the pre-defined pass/fail limit signals a leak in the container.

As the pharmaceutical industry continues to evolve, adopting specialized CCI testing enhances product quality and builds trust in the supply chain. Prioritizing precise and thorough CCI evaluations contributes to safer and more reliable radioactive pharmaceuticals in the market.
