The invention relates to a storing device, especially a climatic chamber, for storing laboratory equipment, especially microtiter plates, on shelves (4). The storing device comprises a shelf-servicing device which has an upper and lower horizontal guide (15, 15') between which a vertical guide (16) is disposed. A horizontal motor (18) drives the vertical guide (16) along the upper horizontal guide (15). A shaft transmits this movement to the lower end of the vertical guide (16) and drives a pinion which acts as an additional drive along the lower guide (15'). The inventive device prevents the vertical guide (16) from tilting during start-up and slow-down. The vertical guide (15) is guided on its upper and lower end in the upper and lower guide (15, 15'), respectively, in a rotationally fixed manner, thereby avoiding torsion of the vertical guide.
