Abstract
An apparatus for mixing of liquid substances or distribution of solid substances in liquid substances in a plurality of sample containers arranged in a microplate (7) is supported on a horizontally displaceable support plate (2). A motor (3) that is provided with an unbalance is held via its stator (3A) above a base (1) directly on the underside of the support plate (2), the rotational axis (D) of the rotor (3B) being disposed perpendicular to the support plate (2). The support plate (2) with the motor (3) rests on at least three horizontally elastically movable bearing elements (6), whose points of attachment to the base (1) and to the support plate (2) are chosen such that the support plate (2) with the microplate (7) in the idle position assumes a specified position in the X-Y plane due to the reset force of the bearing elements (6), and in the shaking mode, as a result of the lateral, directionally identical deflection of the bearing elements (6) effected by the unbalance of the motor (3), performs a horizontal, non-torsional shaking movement against the reset force of the bearing elements. In the process, all sample containers of the microplate (7) describe an identical orbit …
