0.1µm AseptiCap KS 1″, 2″, 5″, 8″



AseptiCap KS PES membrane capsule filters are validated for mycoplasma removal and are used for sterile media filtration in mammalian cell culture. The filters meet key process requirements such as high retention efficiency, very high protein recoveries, extremely low extractables, high throughputs, wide chemical compatibility etc.

Special features

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
