Polytetrafluoroethylene (PTFE) membranes are unaffected by most organic solvents, concentrated acids and bases, propellants, and cryogenic fluids

• Ideal for sterilization of gas and alcohols; cleaning acids, alkalies, and organic solvents; venting purposes.
• Use with aggressive chemicals

Filters are Triton-free and have a bidirectional membrane support and luer lock (15/25 mm dia) or stepped barbs (50 mm dia) inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.
