GBM-L1 Vacuum Decay Leak Detection Tester is used to perform micro leakage detection on finished packaging by vacuum decay method. It is suitable for leak detection for the integrity of various packaging containers and applied to ampoules, vials, HDPE bottles, prefilled needles and other pharmaceutical packaging, food packaging, and chemical industry packaging. It is advantageous in its’ non-destructive, non-damage and sample-free preparing characters. Our company is always committed to escorting the quality of medicines and foods.
Test Principle
In accordance with ASTM F2338, YY-T 0681.18-2020 and USP1207 standards, GBM-L1 is based on vacuum decay method with dual sensor technology and dual circulation system. The machine main body should be connected with specially-designed test cell contained with tested package.
The instrument evacuates the test cell, and a pressure difference is formed between the inside and outside of the package. Under pressure difference, the gas in the package diffuses into the test cell through the leak hole. The dual sensor technology detects the relationship between time and pressure and compares it with the standard value to determine whether the sample leaks.
