Vivaspin® 15R Centrifugal Concentrator

Up to 15 ml starting volume
Concentrate up to 400x

Vivaspin 15R centrifugal devices allow rapid concentration of protein and nanoparticle samples up to 15 ml in volume. They can be used in rotors accepting 50 ml centrifuge tubes. The patented twin vertical membrane design minimizes filter fouling while the Hydrosart® regenerated cellulose membrane provides maximum recovery even for antibodies and dilute proteins. The built in dead stop pocket allows maximum concentrate recovery.
