PROBLEM TO BE SOLVED: To provide a stirring device which permits satisfactory magnetic force transmission by reducing/preventing mutual magnetic interference even when adjacent magnet rotators 3 are proximately arranged by themselves, permits such an accurate synchronous rotation control that the rate of respective stirrers 4 can optionally be changed from low rate to high rate or to a constant rate, allows a dispensing process in which a chemicals delivery instrument arranged with a standard pitch and a dispensing device etc. are utilized to be shifted as a stirring process as it is and permits the simplification of operation process and enhancement of operability. SOLUTION: The magnet rotators 3 are arranged as a set for a plurality of vessels 2 and are loaded successively so as to synchronously rotate with a relation of a pair to the stirrers. The magnet rotators 3 are arranged with different magnetic axial directions so that magnetic poles of the adjacent magnets 32 are not placed oppositely to one another at a rotating position. Otherwise, the magnetic poles are constituted so that the lines of magnetic force are oppositely operated in the vertical direction and the stirrers 4 are set to a size shorter than the width of S-N magnetic pole of the magnet.
