ABSTRACT:
The contents of a two-dimensional array of vessels are mixed by a vortex created by continuous lateral tumbling of a magnetic stir element against the interior side wall of each vessel. The system includes a drive magnet having oppositely polarized sides, and a carousel including receptacles at different heights and at different positions about the carousel's axis of rotation for receiving a plurality of arrays of vessels. The magnet's vertical physical axis is aligned with the carousel's axis of rotation so that the magnet is disposed to one side of each of the receptacles. The magnet provides magnetic flux lines that rotate horizontally through 360 degrees within the received vessels when the magnet is rotated about its vertical physical axis to thereby cause magnetic stir elements in the vessels to continuously tumble laterally against the interior side wall of the vessel and thereby create the vortexes.
