0.1µm AseptiSure WS 5", 10", 20", 30"

mdi AseptiSure WS are low protein binding hydrophilic PVDF membrane cartridge filters offering serial filtration incorporating a large pore size upstream membrane to protect the downstream membrane for enhanced throughput.

These cartridge filters are validated to meet compendia and regulatory requirements and are well characterized. They meet key process requirements such as absolute retention efficiency, extremely low extractables, high throughputs, wide chemical compatibility and other important characteristics.

  • Absolute retention
  • 100% integrity tested
  • Low protein binding
  • Low extractables
  • Cell Culture Media
  • Growth Regulators
  • Small Volume Parenterals
