AseptiCap KSO 1", 2", 5", 8"

mdi AseptiCap KSO are polyethersulfone membrane capsule filters offering wide pH (1-14) compatibility. These filters are specially designed for alkaline fluid streams in bio-pharma manufacturing processes, with added advantage of high throughputs and low hold up volumes.

These capsule filters offer serial filtration incorporating a large pore size upstream membrane to protect the downstream membrane for enhanced throughputs.

AseptiCap KSO are validated for use in pharmaceutical and bio-pharmaceutical applications.

  • Wide pH compatibility (1-14)
  • Absolute retention
  • Low protein binding
  • Light weight and self supporting
  • Low hold up volume
  • Very high flow rates
  • 100% Integrity tested
  • Total traceability
  • Scale up of new drug delivery systems
  • Bioburden removal from cell harvest supernatants
  • Sterilization of bio-pharmaceuticals such as vaccines and therapeutic proteins
  • Sterilization of oncology drugs
  • Sterilization of buffers
