Sartorius VS0162 Vivaspin 500, 1,000,000 MWCO PES

One step procedure for small sample amounts. Vivaspin centrifugal concentrators are disposable ultrafiltration devices for the concentration of biological samples. Vivaspin 500 centrifugal filter units offer a simple, one step procedure for sample concentration with starting volumes. They can effectively be used in fixed angle rotors accepting 2.2 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and provides high speed concentrations. Vivaspin 500 units are available with PES membrane in a wide range of molecular weight cut-offs. Concentrate recoveries of 90% can be reached in less than 30 min. The dead stop pocket prevents concentration to dryness.
