Abstract
A microtiter plate (1), which can be used in a device G, comprises a plurality of receptacles (2) disposed next to one another for a substance or fluid to be stirred and analyzed, wherein stirring rods (3) are provided for stirring. So as to drive these stirring rods, it is provided that the bottoms (4) of the individual receptacles (2) are displaceable and deflectable and that a stirring rod (3) penetrates each of them centrally, the rod being seized by a drive on an outer section (3b) protruding downward beyond the bottom (4) such that it can be set into a back and forth motion or a gyrating or rotary motion and thus continues the desired stirring motion on the inside of the receptacle (2).
