Sartobran® MidiCaps® 0.45µm

Sartobran® P with its unique low-binding cellulose acetate (CA) membrane is mainly used for the sterile filtration of blood & plasma products and vaccines. The ultra-low binding of the membrane material leads to highest product yield and exceptional filtration performance. Especially large, shear-stress sensitive proteins do not lose their structure and function when filtered through this special membrane. This will improve your product yield even further.

Availability:  On Request

Sterilizing-Grade, 0.2 µm Rated Filters
Sartobran® P Pore size: 0.45 | 0.2 µm (heterogeneous CA double layer)

Bioburden Reduction, 0.45 µm Rated Filters
Sartobran® P Pore size: 0.65 | 0.45 µm (heterogeneous CA double layer)

Your Benefits:

  • High product yield due to ultra-low unspecific adsorption
  • Excellent filtration results especially for large, shear-stress sensitive proteins
  • Exceptional total throughput especially for blood and plasma products

Sartobran® P filters are not suitable for gamma irradiation. Please check also Filter Transfer Sets for easy integration of non-gamma filters into single-use assemblies.
For highest process flexibility all Sartobran® P filters are available for conventional or single use applications. All filter elements are available in various sizes and adapter combinations. Please review the selection guide in the supporting resources literature.
