Whatman™ Puradisc™ H-PTFE syringe filter contains a hydrophilic membrane that is chemically stable and inert. The H-PTFE membrane exhibits low protein binding and can be used for both aqueous and aggressive organic solvents. Whatman™ Puradisc™ H-PTFE syringe filters combine high quality with cost-efficiency. A true work-horse in the lab, these filters are well suited for rapid, routine syringe filtration in a busy, high volume lab. The H-PTFE membrane is suitable for HPLC and uHPLC sample preparation as well as many other applications, as its dual capability handles most solvents.

• Can be used with both aqueous solvents and aggressive organic solvents
• Suitable for sample preparation for high performance and ultra-high performance liquid chromatography (HPLC and uHPLC)
• Choice of 13mm or 25mm syringe filter diameter to suit sample volume
• Choice of 0.2µm or 0.45µm pore sizes for retaining a variety of particles
• Suitable for rapid syringe filtration of samples up to 100mL
