Cytivas Whatman Uniflo 30 mm with Glass Fiber (GF) Prefilter are disposable filter units designed to provide clean filtrate from small volumes up to 100 mL. They feature a polypropylene overmold housing and are individually laser etched for easy filter identification. The Prefilter is manufactured from pure borosilicate glass and offers very fine particle retention and good loading capacity and flow rate.

Polytetrafluoroethylene (PTFE) membrane is hydrophobic and will not allow water to pass without high pressures. Aqueous solutions may be filtered if the membrane is initially wetted with alcohol or another appropriate solvent. Polytetrafluoroethylene membrane will stop aqueous aerosols in gas streams.
