Unlaminated PTFE (Teflon^®) Filtration Membranes.

Pore Size: 5.0µm. Diameter: 37mm. Pack of 50.

PTFE (Teflon^®) polytetrafluoroethylene membrane consists of a pure PTFE tortuous pore structure. PTFE membranes are unsupported. The larger pore sizes 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.

The unlaminated filters are compatible with strong acids, aggressive solvents and high temperatures, which can soften the polypropylene support of laminated GE PTFE. These filters are ideal for applications requiring stringent temperatures or chemicals without adding particulates to the filtrate. In addition, since GE 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, GE PTFE requires pre-wetting with alcohol to establish flow with reasonable pressure differentials.
