AseptiCap WS 5", 10", 20", 30"

mdi AseptiCap WS are low protein binding hydrophilic PVDF membrane capsule filters offering serial filtration incorporating a large pore size upstream membrane to protect thedownstream membrane for enhanced throughput.

These capsule filters are validated to meet compendia and regulatory requirements and are wellcharacterized. They meet key process requirements such as absolute retention efficiency, extremely lowextractables, high throughputs, wide chemical compatibility and other important characteristics.

  • Absolute retention
  • 100% integrity tested
  • Low protein binding
  • Low extractables
  • Very low hold up volume in filters

Sterile Filtration of:

  • Antibodies
  • Protein Solutions
  • Buffers
  • Vaccine concentrates
  • Small Volume Parenterals
