Polypropylene (PP) syringe filters
Whatman polypropylene syringe filters have high and uniform tolerance to heat and mechanical stress. The slightly hydrophobic membrane is resistant to a wide variety of organic solvents.

Puradisc syringe filters for routine syringe filtration
Cytiva''s Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of filtration applications. Puradisc is available in a range of filtration media to filter samples of diverse chemical solvents, compounds and sample types. Filtration materials include: regenerated cellulose (RC), cellulose nitrate, nylon, polytetrafluoroethylene (PTFE), polyethersulfone (PES), polypropylene, polyvinylidene difluoride (PVDF), and cellulose fiber acetate.

Puradisc syringe filters are well-suited for a wide variety of sample types and applications, including capillary electrophoresis(CE), biological sample preparations and analysis, protein filtration, UV spectroscopy and high performance liquid chromatography (HPLC).

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.
