Sartobind® S Cassette 0.8 L, 4 mm bed height

Sartobind® S membrane adsorber units combine the advantages of convective media and ion exchange chromatography for rapid and easy contaminant removal or capture of virus and virus like particles.

The cassette design eliminates the 5 L size limitation for membrane adsorbers and offers simple pod-like modular system up to 100 L membrane volume.

Sartobind® S membrane adsorbers display a macro-porous structure with pore size of > 3 µm. Sulfonic acid ligands are bound covalently to the complete internal surface of the membrane, resulting in separation media of high binding capacity combined with exceptional high flow rates.


The S membrane adsorber is successfully used in FDA-approved drug manufacture to remove host cell proteins at high flow rates. As a cation exchanger it displays not only aggregate removal capabilities but typically at least ten-fold higher binding capacity for viruses and virus-like-particles (VLP).


The Sartobind S adsorber speeds up the production process by high flow rate and opens new opportunities for the purification of therapeutic proteins and vaccines.

  • High speed host cell protein removal up to 30 bed volumes/ min
  • Aggregate removal

Easy to use:

  • Plug and play devices from 0.08 ml to 5 l
  • Can be used like a filter
  • Flow rate up to 30 bed volumes/min
  • Disposable or re-usable
