Sartorius Lab Instruments GmbH & Co. KG Membrane Adsorber Units For Ion Exchange Chromatography 93IEXS42DB-12--V

Sartobind membrane adsorbers (MA) for ion exchange chromatography are ready-to-use syringe filter type units. They all are based on the patented Sartobind membrane that displays a microporous structure with pore size of > 3 µm. Ligands for ion exchange are bound covalently to the complete internal surface of the membrane, resulting in separation media of high binding capacity combined with very high flow rates. Binding of ion exchange ligands is very stable and allows many cycles of re-use without loss of binding capacity. Sartobind MA units for ion exchange are available as strong or weak anion (Q and D) and strong cation (S) type and in four sizes between 5 cm² and 100 cm² membrane area, corresponding to static binding capacities between 3 mg and 80 mg protein per unit. Sartobind MA units are equipped with standard Luer Lock connectors and can be run with HPLC or FPLC systems or even by hand with a syringe. While Sartobind MA 5 units with a single membrane layer are intended for initial testing and single use only, the larger units with polysulfone housings are compatible with many solvents applied in chromatography and can be re-used > 100 times.
