Ptfe Membrane Disc Filter Paper

SS Filters 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 120A C.

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

FEATURES & BENEFITS
a cAbsolute filtration
a cWide chemical compatibility
a cNon fiber releasing
a cWell defined maximum pore size
a cHeat & chemical resistant
a cExtremely low extractable
a cNaturally hydrophobic
a cMust be prewetted with ethanol or methanol for products containing water.
APPLICATIONS
One of the major applications for PTFE membrane is the clarification of corrosive solvents and aggressive fluids. Air & gas sterilization make use of the hydrophobic characteristics of PTFE membrane and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 & 0.45 microns.
Applications include:
a cHPCL solvents & sample filtration
a cSterile venting of vacuum manifolds, fermenting vessels
a cSterile filtrate tanks & containers
