FlowFilt PTFE Membrane Disc Filter Paper

FlowFilt PTFE Membrane Disc Filter Paper

SS Filters FlowFilt PTFE membranes are chemically stable and inert. They are suitable for applications involving aggressive organic solvents, strong acids and alkalies. 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 on to a non woven polypropylene support web for improved strength and handling and can be used at temperatures upto 120ºC.

PTFE is the membrane of choice for use with aggressive solvents, liquids and gases that can attack other membranes.
