MLT-01 vacuum decay leak tester is based on ASTM F2338 and is high resolution micro leak tester used for pharmaceutical industry.


MLT-01 is a vacuum decay method leak tester that can evaluate an overall performance of a sealed package form. It’s a non-destructive testing method that measures the pressure change between sample it's sourrounding environment(sample chamber).

Test Principle:

It follows ASTM F2338 and can be used to identify gross and micron leaks in packaging for food, pharmaceutical and medical devices, etc. Configuration of test range varies based on sample type and leak rate.

Technical Features:
