mdi AseptiPrime® KS are sterilizing grade PES membrane large capsule filters specially designed for very high throughputs. The special asymmetric pre-filter membrane layer with high asymmetric proportion offers high loading and volume handling capacities to provide enhanced protection to the final membrane layer.

These are available in a wide range of sizes and end connections to suit a multitude of sterilization applications in biopharmaceuticals for process development, pilot scale and production batch sizes.

These filters meet key process requirements such as high retention efficiency, very high protein recoveries, extremely low extractables, high throughputs, wide chemical compatibility etc.

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