Product Information

Whatman Teflon (PTFE) Membranes (TE36)  

Pore size 0.45µm, diameter 47mm

WTP membranes use a polypropylene grid as the support material whereas the TE range use a randomly arranged polypropylene support material.                                                                           

One of the major applications for the PTFE membrane is the clarification of corrosives, solvents, and aggressive fluids. This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5 µm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 µm and 0.5 µm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 µm membranes.
