Introduction Vivaproducts Vivaspin 2 centrifugal filtration centrifuge tubes from Wolflabs. The Vivaspin 2 bridges the gap between the 500 µl and 4 ml centrifugal concentrators. This device combines the speed of the classic Vivaspin products with low internal surface and membrane area for superior recoveries from very dilute solutions.
Features and benefits - Available with a choice of polyethersulfone, cellulose triacetate and Hydrosart membranes, Vivaspin 2 offers the highest flexibility for process optimisation. - Also unique to the Vivaspin 2, is the choice of directly pipetting the concentrate from the dead stop pocket built into the bottom of the concentrator, or alternatively reverse spinning into the concentrate recovery cap which can then be sealed for storage.
