Product Introduction
Hydrophilic polyvinylidene fluoride (PVDF) membranes are hydrophilically modified based on hydrophobic PVDF membranes, reducing the surface contact angle and enhancing hydrophilicity. Hydrophilic PVDF membranes exhibit extremely low protein adsorption while maintaining exceptionally high water flux and broad chemical compatibility. Consequently, PVDF membranes are frequently used for filtering culture media and other protein solutions. We offer filter membranes with pore sizes ranging from 3 μm to 0.1 μm.
Product Advantages
- Good chemical compatibility
- Ultra-low protein adsorption
- Multiple aperture sizes to meet different needs.
- Excellent hydrophilicity
- Good heat resistance
Product Use
- Solvent filtration
- Sterilizing filtration
- Biopharmaceutical
