Membrane filter PVDF

hydrophiliclaboratorymedical

Product Introduction
Hydrophilic PVDF membranes are hydrophilic modifications of hydrophobic PVDF membranes, designed for low protein adsorption and high flux. They are commonly used for filtration of culture media, protein solutions, solvent filtration and chromatographic sample preparation due to broad chemical compatibility and thermal/oxidation resistance.

Features

• Ultra-low protein adsorption and low extractables.
• High porosity with uniform pore structure.
• Broad chemical compatibility for solvents and mobile phases.
• High throughput and water flow rate.
• Excellent heat and oxidation resistance.
• Consistent inter- and intra-lot performance.
• Compatible with common sterilisation methods: autoclave, EO, gamma irradiation (verification required for specific times/doses).
• Hydrophilic surface for rapid wetting.
• *Sterilization times/doses vary depending on the customer’s processing technology and sterilization conditions; corresponding verification is required.

Applications
Suitable for filtration in food & beverage, pharmaceutical, microelectronics, industrial processes, water treatment and laboratory use.

• Chromatographic sample preparation, mobile phase filtration, clarification filtration.
• Media and buffer filtration for cell culture and downstream processing.
• Drug sterilisation, particle removal, particle analysis and determination.
