VAC-VBS Gas Permeability Tester

VAC-VBS is based on the differential pressure method, and can be used for determination of gas transmission rate of films, sheeting, high barrier materials and aluminum foils.

Benefits :

  • Increase sample throughput
  • Availability for testing various gases including O2, N2, CO2, Air, as well as explosive gases such as CH4, H2, etc.
  • Improve physical properties of materials and develop new materials
  • Films
    Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
  • Sheeting
    Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC
  • The GTRs of various films for distinct gases are testable
  • Tests 3 equivalent specimens at one operation and exports test results in average value
  • Equipped with temperature control device (optional parts) to meet various test conditions
  • The instrument comes with two test modes: proportional mode and standard mode
  • The system is controlled by computer and test process is automatic
  • Reference film for fast calibration to ensure accurate and universal test data
  • Equipped with RS232 port for convenient data transfer
  • Supports LystemTM Lab Data Sharing System for uniform management of test results and test reports
