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.
