The invention provides a storage device with storage racks and a shaker where the undesired horizontal oscillations of the upper ends of the storage racks are small. For this purpose, rotating bodies with non-horizontal end faces are provided, each of which is contacted by a follower member, with the follower member carrying out an up and down movement when the respective rotating body rotates. In a second embodiment, a moving counterweight assembly is provided that counteracts the oscillations. The counterweight assembly is connected to the upper end section of the storage racks and includes a vertically displaceable counterweight. The counterweight is mounted eccentrically on rotating tables.

The invention claimed is: 1. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, and a moving part driven to move opposite to the shaking motion, wherein the moving part comprises a vertically displaceable counterweight. 2. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, and a moving part driven to move opposite to the shaking motion, wherein said moving part is moveable between an upper and an lower support, wherein the upper support is rigidly connected to the upper end section of the of the storage rack. 3. The storage device of claim 2 further comprising rotating tables mounted to the upper and lower supports for eccentrically mounting said moving part. 4. The storage device of claim 3 further comprising an eccentric member, wherein said rack carrier is mounted to said eccentric member and wherein the rotating table and the eccentric member are driven synchronously and with equal rotational speed. 5. The storage device of claim 4 further comprising a driving belt for commonly driving said eccentric member and said rotating table. 6. The storage device of claim 2 wherein the upper support comprises a strut connected to the upper end section of the storage rack. 7. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, and a moving part driven to move opposite to the shaking motion, wherein a mass of the moving part multiplied by an amplitude of motion of the moving part corresponds substantially to a mass of the storage rack or storage racks and the rack carrier multiplied by an amplitude of motion of the rack carrier. 8. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, and a moving part driven to move opposite to the shaking motion, wherein an amplitude of motion of the moving part is larger than an amplitude of motion of the rack carrier. 9. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least two storage racks arranged on the rack carrier, which storage racks comprise storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, and an upper support comprising a strut connected to the upper end sections of all storage racks. 10. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, and a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, wherein the counterweight assembly extends through an opening or recess of the rack carrier. 11. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, and a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, wherein the counterweight assembly comprises a counterweight carrier extending from a height of said rack carrier to a height of the upper end section. 12. The storage device of claim 11, wherein the counterweight carrier is driven to an oscillating motion in opposite phase to the shaking motion. 13. The storage device of claim 12 further comprising a counterweight mounted on the counterweight carrier arranged between the height of the rack carrier and the height of the upper end section. 14. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plurality of laboratory samples on top of each other, and a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, comprising several storage racks and operable to shake only a first set of said storage racks while a second set of said storage racks remains at rest. 15. A storage device for laboratory samples comprising: a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises vertical side walls having a plurality of ledges forming storage locations for a plurality of laboratory samples on top of each other, a counterweight assembly connected to an upper end section of the storage rack and being driven to exert a force opposite to the shaking motion in order to counteract an oscillation of the upper end section of the storage rack, a carousel carrying a plurality of said storage racks, and a rotational drive for rotating the carousel about a vertical axis. 16.
