Provide a single-step procedure for sample preparation, providing rapid sample filtration and concentration. Comprise centrifuge tube filtrate container with insert containing patented vertical membrane and thin channel filtration chamber. A wide choice of membrane materials is available for compatibility with most sample solutions, and low hold-up and dead-stop volumes ensure recoveries from small samples.
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 be sealed for storage. Both methods result in near total concentrate recoveries.
