PharmaDoer PVDF Series polyvinylidene fluoride (PVDF) pleated filter cartridges provide highly efficient submicronic retention of particulates and can deliver fully retentive sterilizing performance for microbial bio-burden in the preparation of pharmaceutical and biotechnology fluids. The PVDF membrane excels in its very low protein binding. The hydrophilic membrane allows for fast and easy wetting in aqueous fluids. Cartridges receive a thorough ultrapure water rinse to assure product cleanliness. Cartridges are 100% integrity tested by forward flow diffusion to assure optimized retention performance.
