Hydrophobic PVDF Membrane Filter Rolls


Hydrophobic PVDF Membrane Filter Rolls are a versatile 100% high temperature resistant polyvinylidene  difluoride membrane. It is designed to provide strength, flexibility and chemical compatibility to meet the rigorous and demanding requirements of chemical filtration applications. Incorporated with no wetting agents, filtration membrane is also an ideal cost-effective alternative to polytetrafluoroethylene membrane to prevent moisture blockage in venting and gas filtration.

The Hydrophobic PVDF Membrane Filter Rolls do not require the use of wetting agents, transmitting negligible extractables and increasing sample purity during sterilization or clarification procedures. Because of their exceptionally low protein binding our PVDF filters are well-utilized in the preparation of proteinaceous solutions for chromatography and other instrumental analyses. Hydrophobic PVDF Membrane Filter Rolls Broad chemical compatibility allows PVDF filters to accommodate a wide range of applications especially those requiring high flow rates/throughput.

*Hydrophobic membrane
*Extremely low extractable/protein binding
*High flow rates and throughputs
*Ideal for the removal of HPLC contaminants most likely plug columns and damage analytical results
