Whatman Puradisc micron syringe filters from Cytiva's offer a versatile solution for analytical sample preparation needs. They are a variety of options available to suit all labs needs, and are well-suited for routine syringe filtration of samples up to 100 ml for a range of applications, including high performance liquid chromatography (HPLC) and capillary electrophoresis (CE).

• Choice of 13 or 25 mm Ø non sterile syringe filter to suit filtration sample volume
• Sub-micron pore sizes, 0.2 and 0.45 μm, for fine particle retention to protect instruments and chromagraphy columns
• Autoclavable for sterile sample preparation
• Also available with depth polypropylene (DpPP) filtration medium
• Recyclable after use

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.

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.
