These Corning syringe filters have acrylic copolymer housings, female luer lock inlets and male luer slip outlets. Polyethersulfone (PES) membranes provide the fastest flow rates, low protein binding and low extractables. 100% integrity tested, sterile and certified nonpyrogenic and noncytotoxic. Manufactured in accordance with ISO 9002 standards.
A 50 mm diameter non-sterile syringe filter with a 1 µm filter pore size hydrophobic PTFE membrane. The 1 micron filter comes in a pack of 10. A 4 mm diameter sterile syringe filter with a 0.22 µm pore size hydrophilic PVDF membrane. Comes in a pack of 100.
PTFE is inert to most chemically aggressive solvents, strong acids and bases and can be used for solvent clarification and HPLC sample prep. PTFE membranes are available unsupported and supported. PTFE membranes with a laminated polypropylene web support to one side offers improved handling characteristics.
