Container Gas Permeability Analyzer

Product catalog summary

Overview: The document provides detailed information about a gas permeability tester developed by Labthink Instruments Co., Ltd. This instrument is designed to measure the gas transmission rate (GTR) of various finished package containers using the differential pressure method.

Professional Technology:

The instrument can measure GTRs for gases such as air, oxygen (O2), carbon dioxide (CO2), and nitrogen (N2).
It features a patented structure and test method to address container testing challenges.
Three testing cells are available, allowing for the average value of three specimens to be obtained in one operation.
Both the inner and outer chambers of the test containers are evacuated to ensure accurate data.
The system is computer-controlled with automatic test processes and includes professional software for intelligent operation and data analysis.
Equipped with an RS232 port for data transfer and supports the Lystem Lab Data Sharing System for managing test results and reports.

Test Principle: The instrument operates by mounting a pre-conditioned hollow container in a gas diffusion cell to form a sealed barrier. The chambers are evacuated, and test gas is introduced to create a pressure difference, allowing gas permeability to be measured.

Applications:

Basic Applications: Suitable for testing gas permeability of containers such as bottles for carbonated drinks, juices, edible oils, tea, dairy products, washing supplies, and metal packages.
Extended Applications: Can test permeability for various gases including O2, CO2, N2, air, and mixed gases.

I PERME® G2/130 Container Gas Permeability Tester This instrument is based on the differential pressure method, and professionally applicable to the determination of gas transmission rate of finished package containers. Test gases could be air, oxygen, nitrogen, and carbon dioxide, and testable containers include various bottles of carbonated drinks, juice, tea, as well as packages of edible oil, dairy products, washing supplies and metal containers. Professional Technology • The GTRs of the whole hollow containers for distinct gases(air,02, C02, and N2) are available • Patented structure design and test method effectively solve problems involving container tests • 3 testing cells are available, where the average value of three specimens could be obtained at one operation • Both inner and outer chambers of test containers are evacuated to ensure accurate and effective test data • The system is controlled by a computer and test process is automatic • Professional operating software integrates intelligent operation with multi-function data analysis • Equipped with RS232 port for convenient data transfer • Support Lystem™ Lab Data Sharing System for uniform management of test results and test reports Test Principle The pre-conditioned hollow container is mounted in the gas diffusion cell as to form a sealed barrier. The inner and outer chambers of container are evacuated firstly, followed by the evacuation of the entire cell. A flow of test gas is thereafter introduced into the evacuated outer chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure difference of inner chamber. This test instrument is applicable to the determination of gas permeability of: Test the gas permeability of finished package containers, e.g. carbonated Containers drinks bottles, juice bottles, edible oil packages, tea drinks bottles, dairy product packages, washing supplies packages and metal packages Extended Test the permeability of various types of gases, e.g. 02, C02, N2, Air and Various Gases Technical Specifications Specifications Container Test Range 0.0001 ~ 1800 mL/pkg-day Vacuum Resolution 0.1 Pa (standard) Labthink Instruments Co., Ltd.144 Wuyingshan Road, Jinan, P.R.China (250031) Phone: +86-531-85068566 FAX: +86-531-85812140
