At the gas permeation stand, thin films (foils, gels) can be examined for their barrier properties and permeation parameters.

In gas permeation, the transmission rates of thin films can be determined.
- Characterization of barrier properties and permeation parameters of thin films (foils and gels)
- Determination of transmission rates: WVTR (water vapor) following ASTM F-1249, HeTR (helium), OTR (oxygen from air), also of other gases (e.g. H2S).
- Different temperatures and gas humidities are achievable
- Determination of transmission rates: WVTR (water vapor) following ASTM F-1249 and DIN EN ISO 15106-3
