Ultipor® VF Grade UDV20 Virus Removal Filter Cartridges

Robust, Small-Virus Removal Filter with consistent, High Flow Performance

The risk of virus contamination is ever-present in biologic products. Potential sources of virus contamination of biotechnology products include viruses associated with the cell lines (endogenous viruses), or viruses introduced into the cell line or product during from culture medium or during the production process (adventitious viruses). Viruses could potentially be present in donations for plasma derivatives. Ultipor® VF UDV20 Virus Removal Filter Cartridges are direct flow filters that provide an efficient and economical method for removing even the smallest viruses from biological solutions and meet the acceptance criteria of the Parenteral Drug Association’s virus filter task force for small pore size virus-retentive filters.

Features

  • Incorporates Ultipor VF DV20 virus filter membrane
  • Proven, reliable virus safety technology
  • High filtration area per filter cartridge
  • Robust, stable flowrate
  • Resistant to plugging
  • Rigorous quality testing
  • Autoclavable and Steamable In Place (SIP)
  • Automatic in-line integrity test
  • Fully automated systems available

Benefits

  • Robust, high viral clearance for small viruses
  • Approved for use in licensed processes
  • Maximizes process productivity, reduces Cost of Goods
  • Stable flux rates achievable in a wide range of process conditions. Consistent performance (suitable for platform technology)
  • Minimized flux decay
  • Provides assurance of consistent performance per specification
  • Enables a sterile process where required
  • Reduces labor costs, minimizes risk of handling errors
  • Enables the highest level of process control and safety

Robustness and Resistance To Plugging

Ultipor VF UDV20 filter cartridges are characterized by robust and stable high performance, over a wide range of process conditions. The innovative hydrophilic PVDF membrane provides stable pressure/flux capabilities also in more complex or concentrated feeds. The unique, patented laid-over pleating technology provides 2x increased effective filtration area. This allows economical virus filtration of high concentrated protein solutions, without product dilution. Flow decay due to membrane plugging and gel polarization is minimized for a wide range of different process conditions and over long process times, which qualifies Ultipor VF UDV20 filters as platform technology.

High Area-Per-Filter-Cartridge

The Ultipor VF UDV20 filter is an extension to the Ultipor VF Grade DV20 virus filter line. The high-filter-area-per-filter cartridge (due to its unique, patented laid-over pleating construction and narrow core) maximizes process productivity, reduces process costs and reduces the required amount of filter elements per installation, which minimizes the hold up volume of the virus filter system.

Automated Systems

Pall offers fully-automated virus filtration systems that enable precise and consistent operation, together with improved process efficiency. The systems can be designed with steam sterilization (SIP), automated cleaning (CIP) and integrity test in place (ITIP). The Cluster-Filtration Technology assures maximum filter integrity sensitivity. Pall's fully automated virus filtration systems ensures the highest level of manufacturing safety and process performance.

Rigorous Quality Testing

  • 100% Integrity tested – correlated to PP7 bacteriophage removal
  • PP7 bacteriophage lot release test
  • 100% water flow test
  • Protein transmission test
  • Visual inspection control
  • Quality Control at Multiple Production Stages
  • Meets USP Biological Reactivity Test, in vivo, for Class VI-121 °C Plastics
  • Meets Cleanliness per USP Particulates in Injectables
  • Non-Fiber-Releasing
  • Non-Pyrogenic per USP Bacterial Endotoxins (< 0.25 EU/mL)
  • Meets Total Organic Carbon and Conductivity per USP Purified Water; pH per Sterile Purified Water
