Product Introduction

Electronic Leakage Tester applies 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

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.

Intelligent Leakage Tester uses the working principle of pressurizing samples 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 a variety of test modes, which can comprehensively evaluate the tightness and integrity of packaging materials. It has wide applicability, complete functions and accessories,which is comply with ASTM, ISO and GB standards. At the same time, our company provides suitable accessories and services for different samples

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.

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.

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.

Specification

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". It has an audit trail function and multi-level authority settings for users, which can meet the needs of the pharmaceutical industry for data traceability.

u Personalized customization to meet the needs of different samples

For different test samples, it supports customization of suitable test chambers to meet the needs of different tests.

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

Factory configuration

leakage tester 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.

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.
