G2/130 Container Gas Permeability Tester 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.
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 drinks bottles, juice bottles, edible oil packages, tea drinks bottles, dairy product packages, washing supplies packages and metal packages
Test the permeability of various types of gases, e.g. O2, CO2, N2, Air and mixed gas
