Abstract:
A method of mixing the contents of each of a two-dimensional array of vessels, each vessel having a vertical axis as defined when the vessel is disposed for the mixing of said contents, the method comprising the steps of:(a) placing magnetic stirrers within said vessels; and(b) when the vessels are disposed for the mixing of said contents, rotating a permanent magnet about a non-vertical axis of rotation that is so disposed adjacent the array that said rotation of the magnet provides magnetic flux lines that rotate through 360 degrees within a non-horizontal plane within each of the vessels to thereby cause the magnetic stirrers therein to tumble in at least one direction that is other than about the vertical axis of each vessel;whereby the contents of each vessel containing a said magnetic stirrer are mixed by the tumbling of said magnetic stirrer.
