Abstract:
1. A system for mixing the contents of a two-dimensional array of vessels containing magnetic stir elements, wherein each vessel has a vertical axis as defined when the vessel is disposed for the mixing of said contents, the system comprising: means for receiving at least one array of vessels in a disposition for the mixing of said contents; a drive magnet for providing magnetic flux lines; and means for causing the magnetic flux lines to rotate through 360 degrees; wherein the drive magnet is disposed for causing the magnetic flux lines to rotate horizontally through 360 degrees within vessels received by the receiving means to thereby cause the magnetic stir elements in the received vessels to continuously revolve around the vertical axis of the vessel and while so revolving to continuously tumble laterally against the side wall of the vessel; whereby the contents of a said vessel containing a said magnetic stir element are mixed by a vortex created by the continuous lateral tumbling of the stir element against the side wall of the vessel.
