Hydrophilic PTFE Membrane is a thin, unsupported porous film which is treated to be hydrophilic.  This membrane exhibits high flow rates with minimal aqueous extractables.  PTFE membrane is manufactured in a unique way where polytetrafluorethylene (PTFE) is expanded both uniaxially and biaxially.  The resultant membrane is thin, highly porous, and behaves as an absolute retentive membrane.

PTFE offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents.  Typical applications include filtration of solvents and admixtures used in HPLC.  Since a Hydrophilic PTFE filter is optically clear when wet it is ideally suited for culture and microscopic examination of cells or particles captured on the filter surface without requiring a separate step.

Key Features

• Maximum chemical and pH resistance
• High flow rates with minimal aqueous extractables (<0.3% WT%)
• Optically clear when wet with water
• Non-supported
• Thermostable can be used up to 100 °C
• Available in Cartridge, capsule and disposable syringe filter formats
• Pore size: 0.1, 0.2, 0.5 and 1.0 um 
• Diameter: 13 mm, 25 mm, 47mm, 90 mm, 142 mm and 293 mm. 

Typical Applications

• Ideal for HPLC and other mixtures of aqueous and organic solvents 
• Cell culture and microscopic examination 

NOTE:  Hydrophilic PTFE membrane filters are not autoclavable.  Allowing the membrane to dry will render it hydrophobic
