General description
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.
