Polytetrafluoroethylene (PTFE) syringe filter options
The Whatman™ Puradisc™ PTFE syringe filter is a hydrophobic membrane that is chemically stable and inert. It exhibits low protein binding, and its main application is filtration of non-aqueous samples. Prior to filtering of aqueous samples, the membrane must be pre-wetted with a water-miscible organic solvent.

Puradisc is available in the following membrane materials: regenerated cellulose (RC), cellulose nitrate, nylon, polytetrafluoroethylene (PTFE), polyethersulfone (PES), polypropylene, polyvinylidene difluoride (PVDF), and cellulose acetate.

Cytiva also offers high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples.

ISCC+ certified Biobased polypropylene housing (25mm devices):
•90% Biobased plastic resin.
•Biobased plastic resin is ISCC Plus certified using Mass Balance approach.
•The polypropylene accounts for 95% of the weight/composition of the syringe filters.
