Sartobind^® membranes are macroporous, cellulose-based membranes for IEX, methal chelat or (pseudo-) affinity chromatography. The pore structure enables high binding capacity for large molecules at high flow rates.

Overview

Sartobind^® membranes are used for capture of large molecules in bind & elute mode or for polishing in flow-through mode. Diffusion time in adsorbers is negligible because of the large pores and immediate binding of the target substance to the ligands. There is no pore diffusion as given in conventional beads but film diffusion on any point of the microporous membrane structure. At convective flow conditions the movement of the molecules of the mobile phase is directed by pump pressure only. That is why membrane adsorbers feature extremely short cycle times and exceptionally high flow rate and throughput.
