Sartorius® Vivaspin 2, 5,000 MWCO Hydrosart, 25 pcs.

High flow rates due to PES membranes Sample recovery in concentrate > 90% Vertical membrane for fast concentration Compatible with swing-out and fixed-angle rotors Safe concentration due to deadstop reservoir Easy concentrate removal by pipetting Volume graduation for easy reading Description Vivaspin® centrifugal concentrators are disposable ultrafiltration units for the concentration of biological samples. Vivaspin® 500 centrifugal filters allow easy one-step sample concentration and can be used for volumes up to 500 µl in fixed-angle rotors for 2.2 ml centrifuge tubes. Patented design features (vertical membrane, narrow-gap filtration chamber, US 5,647,990) minimize membrane clogging and allow rapid sample concentration even with particle-laden solutions. Vivaspin® 500 centrifugal concentrators are available with a PES membrane in a wide range of different pore sizes ( MWCO). A concentrate recovery of > 90% can be achieved in less than 30 min. Deadstop reservoir in the sample container prevents concentration until the sample dries.
