AseptiCap KL/KS-γ 1", 2", 5", 8"

mdi AseptiCap KL/KS- γ 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. These are gamma sterilizable up to 50 KGy for ready to use gamma sterilized disposable assemblies.

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
  • Sterilization of adjuvants
