Borosilicate glass fiber prefilters combined with cellulose acetate membranes extend the life of the final filter when using viscous, proteinaceous, or particulate-laden samples
- Use these filters to eliminate prefiltration step, reduce retention volume and sample loss, and achieve faster flow rates
Filters are Triton-free and have a bidirectional membrane support and luer lock 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.
