Container Closure Integrity (CCI) Leak Testing

Proven InterTech Microscale Technology measures leaks down to the equivalent of a 0.5 micron defect diameter.

A careful review of application requirements including the Maximum Allowable Leakage Limit (MALL) will dictate the test method used.

Testing is consistent with ASTM requirements (F-3287-17, F-2338-09).

Proprietary technology is available for testing with minimal headspace volumes.

Pressure change, mass flow, and mass extraction under vacuum and positive pressures are available.

These technologies are non-destructive and deterministic allowing manufacturers to comply with GMP guidelines.

Applications include the CCI testing of vials, assay kit assemblies, cups and combined products.
