Vivacell 250

Vivacell 250

50 - 250 ml samples
The Vivacell 250 is a totally new concept for the concentration of larger biological samples. This product offers numerous advantages when compared to stirred cells.

  • One size handles a volume range from under 50 ml to 250 ml.
  • 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.

Unique membrane module takes seconds to replace. Concentrate can be easily monitored through the graduated inspection window.
