Teflon (PTFE) Membranes
Teflon polytetrafluoroethylene (PTFE) membrane consists of a pure PTFE tortuous pore structure. PTFE membranes are available supported or unsupported. The laminated membranes are thicker for easy handling. These filters are chemically and biologically inert, stable up to 260°C (500°F) and will withstand most concentrated acids and bases.
PTFE membrane filters are naturally hydrophobic, they are very useful for aerosol sampling, air venting, and gas filtration, especially in environments also containing water vapor. For filtering aqueous solutions, PTFE requires pre-wetting with alcohol to establish flow with reasonable pressure differentials.
