Vacuum Decay Leak Detection Tester AUTO GBM-L1

The AUTO GBM-L1 Vacuum Decay Leak Detection Tester utilises vacuum decay principles to non-destructively detect micro-leakages in finished packaging. This tester is adept at micro-leak detection and integrity assessment for diverse packaging containers, including vials, ampoules, HDPE bottles, prefilled needles, and more in pharmaceutical, food, and chemical industries. The instrument stands out for its non-destructive nature, eliminating the need for sample preparation.

Test Principle Employing dual-sensor dual-cycle technology, the tester operates on the vacuum decay method with a dual circulation system. The test chamber, designed for the specific package, is connected to the main unit, which initiates vacuumisation. A pressure difference is created, causing gas within the package to diffuse into the test chamber through any leak. Dual-sensor technology monitors the relationship between time and pressure, comparing it with standard values to determine the presence of leaks.
