General description

Whatman Puradisc non-sterile syringe filters with polytetrafluoroethylene (PTFE) membrane combine premium quality with economic efficiency.

Puradisc syringe filters for routine syringe filtration

Puradisc syringe filters cater to a wide variety of sample types and applications, including capillary electrophoresis, biological preparations, protein filtration, and UV spectroscopy sample preparation. Different Puradisc membrane media support diverse chemical solvents and compounds.

Polytetrafluoroethylene (PTFE) syringe filter options

Cytiva′s 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.

Features and Benefits

  • Eight different material options
  • Choice of 4 mm, 13 mm, and 30 mm syringe filter diameter to suit sample volume
  • Range of pore sizes for retaining a variety of particles
  • Optional sterile, medical-grade blister pack
  • Optional tube-tip format for accurate dispensing into a micro-vial

Suitability

Suitable for:
  • HPLC samples containing low solid content
