50 - 250mL samples
Vivacell® 250 is the device of choice 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 50mL to 250mL and can be used in bench top mode or in a refrigerator. Fastest concentration is achieved by use with 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 > 1mL. 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
