Disclosed is an apparatus for mixing laboratory vessel contents. The apparatus has an accommodating adapter with a holder for accommodating laboratory vessels, e.g., laboratory vessels in an exchangeable block module, and a drive for putting the accommodating adapter into a mixing movement which essentially oscillates in a circular and translatory manner in a horizontal plane. The accommodating adapter has a vortex adapter which is accessible from the outside and has a shoulder structure on a circumference. The shoulder structure has at least one shoulder which points toward the center of the circumference and is intended to drive a vessel, e.g., a test tube, which is held and placed from the outside, into the mixing movement in a form-fitting manner.

Laboratory mixer and vortexer

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.
