Whatman PTFE membranes are chemically stable and inert. They are suitable for applications involving aggressive organic solvents, strong acids, and alkalis. PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC. PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents. Chemically stable and inert WTP membranes use a polypropylene grid as the support material whereas the TE range uses a randomly arranged polypropylene support material. WTP and TE membrane ranges One of the major applications for the PTFE membrane is the clarification of corrosives, solvents, and aggressive fluids. This includes the important reShow more
