Large Virus Removal Filter with High Flow Performance

The risk of large virus contamination is a common feature of biologic products.Potential sources of large virus contamination (retroviruses, for example) of biotechnology
products include viruses associated with the cell lines (endogenous viruses), or viruses introduced into the cell line or product during the production process (adventitious viruses).

Large viruses like HIV could potentially be present in donations for plasma derivatives.Pegasus Grade LV6 AB-style Filter Cartridges with Ultipleat® construction
provide an efficient and economical method for removing large viruses like Retroviruses with > 6 log titer reduction or larger virus antibody complexes from biological solutions.The unique Pegasus LV6 membrane in combination with the patented Ultipleat filter construction provides robust high flow rates and total throughput performance which minimizes process costs.The high filter area per filter cartridge reduces the required amount of filter elements per installation and minimizes the hold up volume of the virus filter system.The proven hydrophilic PVDF microporous membrane enables high transmission of proteins also for larger proteins.The filter is delivered pre-sterilized and prewetted which reduces handling time.



  • Robust virus retention
  • > 6 log TR for large viruses
