Abstract: Provided is an automatic analyzer having a rapid start-up of a heat block while precisely controlling a temperature of a reaction solution. In the automatic analyzer equipped with a reaction-vessel-holding part, a heat block having a heat source to heat the reaction vessel, and a cooling system having a low temperature region and a high temperature region, an outer peripheral part of or below the reaction-vessel-holding part is defined as a heat transfer space, there are provided a heat transfer passage connecting the heat transfer space and the high temperature region, a heat medium circulating through the high temperature region, the heat transfer passage, and the heat transfer space, and a flow rate control means configured to control a flow rate of the heat medium in the heat transfer passage, and a temperature detection means is provided on a downstream side of the high temperature region.

Abstract: Provided is a highly reliable temperature adjustment apparatus which uses a temperature adjustment element and quantitatively evaluates the temperature adjustment performance of the temperature adjustment element. The temperature adjustment apparatus is provided with: a temperature adjustment element; one or more temperature detection elements provided near the temperature adjustment element; a calculation unit for calculating the output of the temperature detection element; and a display unit for displaying at least one of a time calculated by the calculation unit as a time at which the temperature adjustment performance of the temperature adjustment is predicted to be below a desired level, the number of operations and the time of current conduction or a warning based on the result of calculation.
