Sartorius, 96IEXS42DN-11--A, Sartobind® S Nano 1 mL with 4 mm bed height

Sartobind S Nano is a 1 mL strong cation exchange membrane adsorber with a 4 mm bed height for rapid small-scale chromatography applications. Sulfonic acid ligands are attached to a reinforced cellulose membrane whose open pore structure supports convective flow through the adsorptive surface. Unlike a packed bead resin column, the membrane architecture provides short diffusion distances and is suited to rapid impurity polishing and selected virus or virus-like particle capture applications. The Nano format provides a practical starting point for screening binding and elution conditions with limited sample volume. The specified configuration uses female Luer-lock connections and has a recommended flow rate of 20 mL/min. Each package contains four membrane adsorber capsules, together with relevant connection adapters. Choose buffer pH and conductivity to support the charge interactions of the intended target. Do not treat this 1 mL membrane device as a 1 mL vial of loose ion exchange resin.
