Sartobind® D A4 Sheet

Sartobind IEX membranes are macroporous, cellulose-based membranes carrying IEX ligands. Binding of charged target molecules takes place at high flow rates.

Sartobind ion exchange (IEX) membranes feature binding sites that are grafted homogenously as an approximately 0.5 - 1 µm film on the inner walls of the reinforced and cross-linked cellulose network. 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..
