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 Technical Parameters Absolute pressure test range (0~300) kPa Differential pressure test range (-2~2) kPa Detection sensitivity 1～3 μm Balance/Test Time 1～3600 s Vacuum time 1～3600 s Set flow rate 0～3 mL/min Test system Dual Sensor Technology / Dual Cycle Test Test chamber  Customized according to samples Suitable for Vials, ampoules, prefilled needles, infusion bottles/bags, etc. Detection principle Vacuum Decay Method/ Pressure Decay Method Host size 495 mm*455 mm*280 mm Ambient temperature 20℃~30℃ Relative humidity Max 80%，no condensation Working power 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. Based on dual-sensor and dual-circulation system technology, high-quality absolute pressure sensor and differential pressure sensor, with an accuracy of 0.1% FS, can effectively detect large and small leaks, accurately calculate the leak hole diameter, and give a pass or fail judgment.   The instrument has low sensitivity and good test repeatability For rigid samples, the detection sensitivity is as low as 1 μm, and the test repeatability is as low as 0.8%. The instrument has stable performance, low noise and good repeatability. u Imported brand accessories, excellent performance Imported brand vacuum pump, pumping rate up to 3 L/s, noise as low as 50 DB, high ultimate vacuum, convenient oil level detection and replacement. The imported gas mass flow controller can simulate micro-leaks arbitrarily, with a resolution of 0.001 mL/min, which provides a reliable guarantee for the method verification of instrument sensitivity. u Large size touch screen, intelligent operation Color 7-inch touch screen, clear view, sensitive touch, easy to operate. Equipped with a micro-printer, USB data interface, and supports PC software measurement and control operation. The test software is designed according to the GMP appendix "Computerized System".

For the same type of samples, it supports customized nesting mode, which can realize the sharing of a test chamber for samples of various specifications.   Application       Freeze-dried powder injection Injection Prefill needle       Eye drops Plastic Ampoule BFS Infusion bags   Factory configuration Standard Host machine, vacuum pump, test chamber and 3 sets of yin and yang control (customized as required), 11-inch touch panel, professional software (GMP) Optional Imported gas flow meters, air compressors, printers, calibration certificates  

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.

The Leakage tester GB-M2 is designed and manufactured in accordance with the relevant provisions of GB/T15171 Test method for leaks in sealed flexible packages. It is used to detect the sealing condition of plastic packaging bags and containers, and it is applied to used in industries of food, beverage, pharmaceuticals, personal care and so on. Through test can effectively compare and evaluate the sealing technology and sealing performance of packaging parts, and provide scientific basis for determining the relevant technical indicators. It can also be used to test the sealing performance of the specimens after dropping and compressing test.

AUTO GBM-D1 intelligent sealing performance tester uses the working principle of pressurizing the sample to test the sealing strength and integrity of packaging materials. It is suitable for food and medicine packaging materials such as flexible, rigid, porous and laminated aluminum foil. There are multiple test modes for comprehensive evaluation of the tightness and integrity of packaging materials. Wide applicability, complete functions and accessories, in line with applicable ASTM, ISO and GB standards. At the same time, our company provides matching accessories and services for different samples.

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

GBPI Electronic Leakage Tester Application: To test the hermetic sealing quality and performance of packaging bags, bottles, cans and so on, used in industries of food, beverage, pharmaceuticals, personal care and so on.
