Whatman™ GD/X PTFE Syringe Filters

Designed to enable the filtration of viscous, hard-to-filter samples greater than 10mL. Whatman™ GD/X PTFE Syringe Filters are 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. PTFE membranes will stop aqueous aerosols in gas streams.
