AseptiCap KL/KS 25mm, 50mm

mdi AseptiCap KL/KS are disposable PES membrane capsule filters offering a convenient lab scale solutions for process development with identical materials of construction for easy scale up to pilot scale and finally production scale filters.

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 o f 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
