Permeability Tester

  • Gas Diffusion Permeability Analyzer

    Model: GDP-V1 The Gas Diffusion Permeameter is used to determine the transport of various gases through membrane-like materials under a wide range of static and dynamic conditions. The instrument is equipped with a high-vacuum vacuum pump to detect very low gas permeability. Various shapes of samples can be tested: flat sheet, hollow fiber, tube...

  • Model: WVTA-9601 The test methods cover the determination of water vapor transmission (WVT) of materials through paper, plastic films, PTFE membrane and other sheet materials. Test dishes filled with distilled water in a controlled dry atmosphere, a constant humidity difference is generated between two sides of the test specimen, the water vapor permeates through the specimen and into the dry side, water vapor transmission rate and other parameters can be obtained by measuring the weight changes of the test dish...

  • Model: AOPT-301 AOPT-301 is based on the coulometric sensor method and is available for the OTR testing of flexible films, sheeting and packages. It can test 3 specimens in one operation with independent results. Films: Plastic films, aluminum foil, aluminized films, plastic composite films, paper-plastic composite films, coextruded films, aluminum foil composite films and others. Packages: Plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. red wine bottles, blister, various plastic bottles, Coke bottles, peanut oil packages, Tetra Pak...

  • Gas Permeability

    The Darcy’s Law Gas Permeability Analyzer is a computer-based automatic test machine that can be used to analyze the performance of a porous media, such as membrane, non-woven, ceramic, fabric…
