Abstract

The invention relates to a multistation mixing device for mixing the contents of laboratory vessels. The device comprises at least two adapter plates having a holder for receiving laboratory vessels and a drive mechanism capable of driving the adapter plates in a mixing motion with the same angular speed such that, in horizontal planes, each point of the adapter plates performs a circular motion with the same radius, the same angle speed and the same angular position around a respective center. The starting positions of the adapter plates, from which the adapter plates are driven by the drive mechanism, are rotated relative to one another by an angle in the direction of the mixing motion in their respective angular position, such that imbalances occurring during the mixing motion are at least partially compensated.
