Labthink’s i-Gastra 7100 Gas Permeability Tester

The i-Gastra 7100 gas permeability tester from Labthink is designed to analyze gas transmission rate of high barrier materials, aluminum foils, sheeting and films. The analysis is carried out based on the manometric or differential pressure method.

The tester is provided with three separate test cells for testing unique samples under each test condition. It can be easily controlled using a monitor, keyboard, and mouse.

Key Features

The main features of the i-Gastra 7100 gas permeability tester are:

  • Extended test range for high-barrier materials and explosive gases
  • Data curve fitting function
  • Standard and proportional modes
  • Automatic temperature control and wide range of humidity control functions
  • Measurement of permeability coefficient, solubility coefficient and diffusion coefficient
  • Patented design of three integrated test cells for better test efficiency
  • Integrated computer control system and Windows-based operating interface software

Basic Applications

  • Films: Including plastic films, plastic composite films, paper-plastic composite films, geomembranes, coextruded films, aluminized films, aluminum foils, aluminum composite films, breathable water-proof films and many other film materials
  • Sheeting: Including engineering plastics, rubber, waterproof building materials, and thermal insulation materials, e.g. PP, PVC, PVDC, and nylon
  • Paper and Paper Board: Including paper and paper board
  • Textiles and Nonwovens: Including textiles and non-woven materials
  • Aseptic Wound Protection Films and Face Masks: Including aseptic wound protecting films, face masks, and protection clothing materials

Extended Applications (Additional Accessories Required)

  • Inverted Cup Method: Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cup required

  • Solar Back-sheets: Including solar back-sheets and OLED packaging materials

  • LCD Monitor Films: Including LCD monitor films
