    Vacuum Decay Leak Detection Tester Package Leaking Test Machine Seal Integrity Testing Equipment

    Brief Introduction

          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.

    It provideprofessional data analysis software, one-click export report function and audit trail function. We have engaged in developing environmentally friendly packaging test equipment. Compared with the traditional color water method, microbial challenge method of leak detection, vacuum decay method is a zero emission, high-efficiency, non-destructive physical testing method. It is the best for manufacturers, inspection institutions and scientific research institutes to detect the leakage of pharmaceutical and food packaging.

    Industry Standard

    ASTM F2338-2009(2013) Standard Test Method for Nondestructive Detection of Leaks in Packages by Vacuum Decay Method

    YY-T 0681.18-2020 Sterile medical device packaging test method,

    United States Pharmacopoeia USP1207 standard

    Industry Application

     Test Principle

    In accordance with ASTM F2338-2009 (2013), 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.
