Omega™ Ultrafiltration Membrane Disc Filters

High Performance and Stability for Users of
Conventional, Non-Disposable Stirred Cells

  • Polyethersulfone membrane provides higher flow rates and lower protein binding than competitive regenerated cellulose. This results in lower processing times and the highest possible recoveries.
  • Discs can be washed and reused.
