Vivacell 250, Insert, Starter Pack 5pc

50 - 250 ml
Gas pressure unit with exchangable ultrafiltration inserts. Operated in stationary benchtop mode or with gentle shaking for increased performance.

Order Number:  VC25S1

Availability:  On Request

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 50 ml to 250 ml and can - for maximum simplicity - 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 > 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 fastest 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 polarisation whilst 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.
