Choice of 13 mm or 25 mm diameter nonsterile syringe filter to suit filtration sample volume. Submicron pore sizes, 0.2 μm 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 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 wellsuited 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). 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.
