Membrane Stack Disc Filters Optimized for Scale Up

For Initial Filterability and Compatibility Studies

  • Used for a wide variety of applications including clarification and prefiltration, sterile filtration, and virus removal.
  • Membranes contain the same materials of construction as larger capsule and cartridge filters.  Simplify scale up and minimize requalification; no need to change materials during transitions to pilot or production scale.
  • Five membrane types offered to assure compatibility with a wide range of fluids and applications:
    • Fluorodyne® II membrane offers high flow rates and is ideal for applications where low protein binding is necessary.  Not recommended with some ethers. 
    • Supor® membrane has high flow rates and throughputs and is ideal for solutions where low protein binding is required.  Not recommended with some ketones.
    • Ultipor® membrane, the industry standard for pharmaceutical filtration, provides broad solvent and chemical compatibility, and low extractables.
    • Posidyne® membrane enhances bioburden and pyrogen removal from aqueous solutions.
    • Preflow™ media is ideal for the prefiltration of biological fluids including cell culture media, serum based products and protein solutions.
