Sartorius Vivaspin® 500. 3.000K MWCO. PES. 25pc. - VS0191
Vivapore® 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 up to 500 l. 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. High flux PES membrane High retentate recovery 90 % Vertical membrane design for ultra fast concentration Universal rotor compatibility Safe sample concentration due to dead-stop volume Convenient concentrate recovery by pipetting Volume graduation for easy reading/monitoring Vivapore® 500 Polyethersulfone. 3 kDa Performance Characteristics Time to concentrate up to 30x [min.] at 20°C Concentrate recovery % Start volume 500 ?l 500 ?l Aprotinin 0.25 mg/ml (6.500 MW) 3.000 MWCO PES 30 96 % BSA 1.0 mg/ml (66.000 MW) 5.000 MWCO PES 15 96 % 10.000 MWCO PES 5 96 % 30.000 MWCO PES 5 95 % IgG 0.25 mg/ml (160.000 MW) 30.000 MWCO PES 10 96 % 50.000 MWCO PES 10 96 % 100.000 MWCO PES 10 96 %
