0.1µm AseptiSure KS Mini 2.5″, 5″



Aseptisure KS 0.1µm double layer PES membrane mini cartridge filters are validated for mycoplasma removal and are used for sterile media filtration in mammalian cell culture.

The upstream PES membrane layer protects the downstream PES membrane layer from premature clogging. The membrane pore structure is specially designed to give high throughputs, thus resulting in better economics

Special Features

Consistent and Reliable Quality: AseptiSure cartridge filters are produced with ISO 9001-2008 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 and higher throughputs with biological streams.
High Throughputs: Translates to lower filtration costs, less number of filter changes and overall economy of operations.
Low Extractables: Means less addition to impurity profile of the biological product from the filters.
