The invention relates to the field of technological processes, particularly, to the laboratory equipment for performing the medical, chemical and micro-biological processes by mixing liquid substances and solutions under the conditions of a micro-climate. The aim of the invention is to control the distribution of the temperature field inside a working chamber. The offered thermo-shaker shown in fig.1 comprises a case (1), a working chamber (2) with a cover (3), a heating element (4) mounted on a movable platform (5) connected with the mechanism of a mixing module (6), capacities (7) with solutions to be investigated, which are fixed on the surface of the electro-heating element (4) and covered by a lift-off lid (8), and an additional heating element (9) mounted on the internal surface of the cover (3). The frequency of cyclic movements and the current through heating elements (4, 9) are controlled by a micro-processor placed in a control unit (10). The surfaces of the heating elements (4, 9) are divided into concentrically arranged heating zones (11-13 and 14-16) the current through which is controlled by the micro-processor, each heating zone containing a temperature sensors (17-19 and 20-22) connected with the mentioned micro-processor.
