Solution – Diffusion Coefficient Analysis SystemGTR-11ADF

Solution – Diffusion Coefficient Analysis System This photo is an example.

This system is able to calculate solution-diffusion coefficient of film-shaped samples. It uses differential pressure method with the digital pressure gauge (JIS-7126-1 pressure sensor method compliant) that can measure permeation delay time and solution-diffusion coefficient. Automatic operation with a data processor.


  • Measure gas permeation delay and calculate solution – diffusion coefficient
  • Differential pressure method with a pressure gauge
  • Easy to test repeatedly with a proprietary software automatically


For research and development of polymeric films
