Temperature control structure for reaction table

Abstract

Abstract PURPOSE:To accurately detect the temperature of a reacting liquid while reducing the heat consumption for heating the reacting liquid by covering the side wall and bottom surface of an annular material which contains a reaction pipe with a heat insulator at an interval and arranging a heat generating body on the bottom surface and a temperature sensor in the side wall. CONSTITUTION:Contact points 56, 61, 62 and 65 brought into noncontact with each other and then the annular material 26 is driven by a driving device to rotate forward or backward, thereby performing specific operation for an automatic analysis. Then the annular material 26 is put in a stationary state and other prescribed operation is performed for the automatic analysis. In the stationary state, the contact points 56, 61, 62, and 65 are brought into contact with each other to perform heating by the heat generating body 36 and temperature detection by the temperature sensor 42. The heat from the heat generating body 38 is conducted directly from the bottom surface 34 of the annular material 25 and the air layer of the gap to the reaction pipe 30 with small heat conduction resistance to heat the reacting liquid in the reaction pipe 30. The temperature of the reacting liquid is controlled through the temperature sensor 42, a control circuit, etc.
