Vivaspin® 2 Centrifugal Concentrator

Up to 2 ml starting volume
Concentrate up to 250x

Vivaspin 2 centrifugal devices allow rapid concentration of protein and nanoparticle samples up to 2 ml in volume. They can be used in rotors accepting 15 ml centrifuge tubes and are available with three choices of membrane. The patented vertical membrane design minimizes filter fouling and the built in dead stop pocket provides maximum concentrate recovery. The Vivaspin 2 also allows reverse spinning of your sample into the upper recovery cap for simplified recovery.
