Pall Ultipor VF grade DV20 filter cartridges are integrity-testable, direct flow filters for size exclusion removal of viruses as small as 20 nm from biological solutions. The innovative DV20 hydrophilic PVDF microporous membrane also enables > 95% transmission of proteins up to 160 kiloDaltons. Using a standard single open-ended (SOE) AB sanitary style cartridge design, Ultipor VF DV20 filters achieve practical flows and pressure drops in process-scale purification of BioPharmaceuticals, tissue and plasma derivatives and protein additives. Where required, suitable prefilters employing the same PVDF membrane material are available, simplifying process optimization and filtration system validation.
