Vivapure® Ion Exchange Protein Purification Products The unique Sartobind membrane adsorber matrix Sartobind IEX membrane adsorbers are based on stabilized regenerated cellulose and display a microporous structure with a pore size of > 3 μm, which is orders of magnitude larger than conventional chromatographic gel materials. This allows molecules to be transported to the ligands immobilized on the membrane adsorber by convective flow, leading to very high flow rates. Chromatography gel beads (right) are shown on top of a membrane adsorber in this SEM picture. The membrane adsorber pores are...
