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.
Cytivas 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.
Cytivas Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. 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.
