PTFE Membranes

PTFE Membranes

These PTFE (Teflon) membranes are available in hydrophilic, hydrophobic, supported, and unsupported options for a wide range of applications involving strong/aggressive acids, bases, and solvents incompatible with most other filtration media.

The laminated membranes are thicker for easy handling. These filters are chemically and biologically inert, stable up to 260°C (500°F) and 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, we offer a full line of hydrophilic PTFE membrane filters from Advantec or our hydrophobic PTFE can be pre-wetted with alcohol to establish flow with reasonable pressure differentials.
