Overview
Ultipor™ VF grade DV20 virus removal filters, part of our Pall filtration portfolio, are robust, stable flowrate small-virus removal filters with consistent, high capacity performance.
- Sanitary direct flow cartridges
- Robust size exclusion mechanism
- ≥ 3 log TR for > 20 nm viruse
- ≥ 6 log TR for > 50 nm viruses
- Low binding for high protein yields
- High transmission of albumin and IgG
- Very low extractables
- Autoclavable and steamable in situ
- 100% integrity-tested (correlated to virus retention)
The innovative DV20 hydrophilic PVDF microporous membrane enables > 95% transmission of proteins up to 160 kiloDaltons. Using a standard single open-ended (SOE) AB sanitary style cartridge design, Ultipor VF grade DV20 virus removal 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
Ultipor VF UDV20 filters meet the acceptance criteria of the Parenteral Drug Association’s (PDA) virus filter task force for small-pore-size virus-retentive filters.
