Can be used with both aqueous solvents and aggressive organic solvents. Suitable for sample preparation for high performance and ultrahigh performance liquid chromatography (HPLC and uHPLC). Choice of 13 mm or 25mm syringe filter diameter to suit sample volume. Choice of 0.2 um or 0.45 um pore sizes for retaining a variety of particles. Suitable for rapid syringe filtration of samples up to 100 mL. Whatman Puradisc HPTFE syringe filter contains a hydrophilic membrane that is chemically stable and inert. The HPTFE membrane exhibits low protein binding and can be used for both aqueous and aggressive organic solvents. Hydrophilic polytetrafluoroethylene (HPTFE) syringe filters Whatman Puradisc HPTFE syringe filters combine high quality with costefficiency. A true workhorse in the lab, these filters are well suited for rapid, routine syringe filtration in a busy, high volume lab. The HPTFE membrane is suitable for HPLC and uHPLC sample preparation as well as many other applications, as its dual capability handles most solvents.
