Pharmaceutical and some food products are expected to be free from microbial contamination and safe to use right from production throughout their shelf-life, but different products and container types necessitate different testing methods according to their content, material of packaging, design and regulatory requirements.
Container Closure Integrity Testing (CCIT), commonly referred to as leak detection, is a non-destructive packaging inspection system to maintain an aseptic barrier against potential contaminants. Is a deterministic testing procedure, so it is less subject to error, is repeatable and gives quantitative and predictable results.

Patient and consumer health and safety is the principal reason why testing methods are put into place.
The United States Pharmacopeia (USP) and Food and Drug Administration (FDA) impose strict requirements for Container Closure Integrity Testing (CCIT).

The method of CCIT chosen will vary according to the desired result like the leak rate measurement of the entire container, potential for microbial ingress, detection of presence of leak paths etc.

CCI failures discovered late in the lifecycle especially after commercial distribution result in extensive financial losses, legal exposure, and damage to a brandโs reputation.ย
Container Closure Integrity is a foundational element of safe and reliable pharmaceutical packaging. In an industry where even, the smallest leak can compromise sterility, efficacy, and patient trust.
CCI testing serves as a critical safeguard for product quality. As regulatory expectations shift toward deterministic, science-driven methods, manufacturers must adopt advanced technologies capable of delivering quantitative, repeatable results.
