The Ambion® Single Tube Magnetic Stand accommodates one 1.5 mL microfuge tube. With this stand, as with any magnetic stand, centrifugation is replaced by the attraction between capture beads in a solution and the magnet in the stand, resulting in the beads collecting on one side of the microfuge tube. Thus, the captured species (e.g., mRNA) is quickly and efficiently separated from the solution's other components.
