VAC-V1 Gas Permeability Tester

VAC-V1 is applicable to the determination of gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, sheeting, foils and finished packages, etc.

Benefits :

  • 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
  • More choices of testing condition controls
  • 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
  • Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation
  • The instrument comes with two test modes: proportional mode and standard mode
  • Test range could be extended based on user requirements to test materials with high permeability
  • High precision temperature control to meet different test conditions
  • Test results could be easily obtained even at extreme condition by data fitting function, which could work at any temperature
  • The instrument could be used to test poisonous, inflammable, and explosive gases (customization required)
  • The instrument is controlled by computer and test process is automatic
  • Reference film for fast calibration to ensure accurate and universal test data
  • Fast-access calibration ports for temperature and humidity, and standard RS232 port for convenient calibration and data transfer
  • Supports LystemTM Lab Data Sharing System for uniform management of test results and test reports
