0.1μm AseptiCap WS-γ 5", 10", 20", 30"

mdi 0.1μm AseptiCap WS-γ are low protein binding Hydrophilic PVDF membrane capsule filters, validated to retain mycoplasma, a critical requirement for sterilization of mammalian cell culture media.

These capsules offer serial filtration incorporating a large pore size upstream membrane to protect the downstream membrane for enhanced throughput.

0.1μm AseptiCap WS-γ capsule filters are validated to meet compendia and regulatory requirements and are well characterized. They meet key process requirements such as absolute retention efficiency, extremely low extractables, high throughputs, wide chemical compatibility and other important characteristics.

  • Absolute retention
  • 100% integrity tested
  • Low hold up volume
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.
