Hydrophobic PTFE membrane is laminated with polypropylene. Excellent chemical resistance against standard organic HPLC solvents. Permits optimal utilization of small sample volumes. Integral, permanently hydrophobic PTFE membranes. Polypropylene support. Extremely high chemical resistance. Whatman ReZist range of syringe filters has been specifically designed to be resistant to organic solvents. These filters are highly suitable for the clarification of aggressive organic solvents. ReZist 30 mm filters can also be used as a venting filter for small vessels.
