Sartorius Vivacell™ 250 PES Centrifugal Concentrators

Description

Vivacell 250 is a totally new concept for the concentration of larger biological samples by pressure ultrafiltration and offers numerous advantages when compared to stirred cells. Vivacell 250 handles a volume range from 50 ml to 250 ml and can - for maximum simplicity - be used in bench top mode or in a refrigerator. Faster concentration is achieved by gentle orbital shaking, at the same time reducing shearing effects. Vivacell 250 features concentrator modules with vertical membranes in order to minimize fouling. The unique conical dead stop built into the bottom of the membrane insert allows concentration to > 1 ml. Setup of the unit and exchange of membrane inserts are extremely easy, the concentration process can be monitored through an inspection window with volume graduations.

• Easy to handle
• High flux PES membrane
• Vertical membrane design for ultra fast concentration
• High retentate recovery > 90 %
• Unit reusable, only membrane insert needs to be replaced

Need for Speed
Use free standing on a bench top or in a refrigerator for maximum simplicity, or use on laboratory shaker for faster concentrations. The unique conical dead stop built into the bottom of the membrane insert allows concentrations to under 1 ml. The gentle vortex action controls membrane polarization while greatly reducing the shear effects typical of stirring mechanisms. Set up or membrane replacement takes just a few seconds. Quick connect fittings and simple screw closure further enhance ease of use.
