Introduction AUTO GBM-L2 Dual-Pressure Methods Vacuum Decay Leak Detection Tester adopts the test principle of vacuum decay method/pressure decay to detect micro-leakage of finished packaging. It can be applied to packaging systems composed of vials, ampoules, Leakage detection of pre-filled needles, eye drop bottles, HDPE bottles, infusion bottles/bags and other pharmaceutical packaging, food packaging, and chemical industry packaging.   Test principle The host is connected to a sealed test chamber customized according to the sample. When performing the vacuum decay method test, the instrument evacuates the test chamber, and a pressure difference is formed inside and outside the sample. Under the action of the pressure, the gas/liquid in the sample enters the test chamber through the leak hole. The main engine uses the absolute pressure sensor and the differential pressure sensor to monitor the pressure change in the chamber to judge whether the sample leaks. When performing the pressure decay method test, the instrument fills the test chamber with a predetermined air pressure, and the gas in the test chamber enters the sample through the leak hole. The host uses absolute pressure sensors and differential pressure sensors to monitor the pressure changes in the chamber to determine whether the sample is leaking.   Standard ASTM F2338-2009(2013),  YY-T 0681.18-2020,  USP<1207.2>, ASTM F2095   Specification Item Parameters Absolute Pressure Testing Range (0 - 300) kPa Differential Pressure Testing Range (-2 - 2) kPa Detection Sensitivity 1 - 3 μm Balancing/Testing Time 1 - 3600 s Vacuum Purge Time 1 - 3600 s Set Flow Rate 0 - 3 mL/min Testing System Dual Sensor Technology/Dual Cycle Testing Testing Chamber Customized according to the sample Applicable Products Vials, Ampoules, Prefilled Syringes, Infusion Bottles/Bags, etc. Detection Principle Vacuum Decay Method/Pressure Decay Method Dimensions of the Main Unit 495 mm455 mm280 mm Ambient Temperature 20℃ - 25℃ Relative Humidity 40% - 60% Working Power Supply AC 220V, 50HZ   Features u Dual-Pressure Methods, to help solve testing difficulties The double combination of vacuum decay method and pressure decay method solves the problem of easy misjudgment and false negative for freeze-dried powder injections containing vacuum in the bottle using a single vacuum decay method.
