AseptiCap® KL/KS 1", 2", 5", 8"

mdi AseptiCap® KL/KS PES membrane capsule filters are available in a wide range of pore sizes, sizes and end connections to suit a multitude of sterilization applications in biopharmaceuticals for process development, pilot scale and production batch sizes.

Consistent and Reliable Quality:
AseptiCap® capsule filters are produced with ISO 9001 certified quality  management systems.
Regulatory Compliance:
Meet all pharmacopeial and compendia requirements and are registered with USFDA DMF #015554
Low Protein Binding:
Results in increased overall product yield
High Throughputs:
Translates to lower filtration costs, less number of filter changes and overall economy of operations.
Low Extractables:
Mean less addition to impurity profile of the biological product from the filters.

  • Bioburden reduction from cell harvest supernatants
  • Filtration of equilibrating, washing and elution buffers for chromatography columns
  • Sterilization of biopharmaceuticals such as vaccines and therapeutic proteins
  • Sterilization of buffers
