Spin Columns, 5 to 20 ml, 116 L x 30 mm W, Polycarbonate, 3000 d Cut-Off Molecular Weight, Protein Concentrator, Polyethersulfone Membrane, 50 µl Dead-Stop, <20 µl Hold-up of Membrane, 6 cm2 Surface Area, 4 to 30°C Storage
Vivaspin™ sample concentrators are designed for fast, nondenaturing concentration of biological samples by membrane ultrafiltration. Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%. The entire process is performed in a single tube with an upper compartment containing sample and a lower compartment separated by a semi permeable membrane with a molecular weight cutoff (MWCO) selected by the user. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber.
