[dense1]

MedArray's PermSelect PDMS silicone hollow fiber membrane modules separate gases from liquid streams or other gases. Silicone is a dense (non-porous) membrane, which operates on differences of permeability in the membrane (solution-diffusion), rather than on molecular weight through pores. The membrane will not "wet out" when used as a membrane contactor and is resistant to fouling.

Applications include:

• degassing water of O₂ or CO₂
• humidifying or dehumidifying gas streams
• VOC removal or concentration from liquid

Multiple sizes are available, from lab scale to production.
