Permeability cells

The permeability cells are available with brass valves and related accessories for normal use and with stainless steel valves for use with contaminated soils. The toxic interface chamber 28-WF0194/3 is recommended to be fit between control panel and permeability cells to avoid toxic permeants from entering control panel. This also prevents contact of air with the permeant, thus no toxic or corrosive vapours can escape into the laboratory.
