Vivaspin 500(500 µl - 5 µl), 300,000 MWCO PES, 100pc
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 up to 500 µl. 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
