Vivaspin 2 Centrifugal Concentrator

Sartorius, VS0201, Vivaspin 2, 10000 Dalton MWCO Centrifugal Concentrator, PES Membrane, 25 pcsVivaspin concentrators are disposable ultrafiltration devices for the concentration of biological samples. Vivaspin 2 bridges the gap between the 500 µl and 4 ml centrifugal concentrators. They can effectively be used in swing bucket or fixed angle rotors accepting 15 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimizes membrane fouling and provides high speed concentrations, even with particle-laden solutions. Vivaspin 2 combines the speed of the classic Vivaspin products with low internal surface and membrane area in order to achieve superior recoveries from very dilute solutions. Another unique feature of Vivaspin 2 is the choice of directly pipetting the concentrate from the dead stop pocket built into the bottom of the concentrator, or alternatively reverse-spinning the concentrate into the recovery cap which can then be sealed for storage. Both methods result in near total concentrate recovery.FeaturesHigh retentate recovery > 90 %Vertical membrane design for ultra fast concentrationUniversal rotor compatibilitySafe sample concentration due to dead-stop volumeConvenient concentrate recovery by pipettingVolume graduation for easy reading/monitoringUnit of MeasurePack of 25 pcs.
