Product Details

This series of filter cartridges are made of hydrophilic polyvinylidene fluoride (PVDF) filter membrane, featuring high flux and high flow rate. Pre-shipment integrity testing ensures high product quality. The low protein adsorption of the PVDF membrane makes the filter cartridge suitable for the sterile filtration of various bioproducts. Simultaneously, the hydrophilicity allows for direct filtration without pre-wetting with organic solvents, greatly improving ease of use.
