PURPOSE:To prevent the decrease in the evaporation of constant temp. water by providing a groove installed in the circumferential direction of a thermostatic chamber and a projecting part having a circumferential shape combined therewith on a reaction disk, thereby forming the spacing between the thermostatic chamber and the reaction disk into a labyrinth shape. CONSTITUTION:This apparatus is constituted to combine the grooves 2 provided on both sides of the thermostatic chamber 1 with the projecting parts 4 of the reaction disk 3 holding a reaction vessel 8. The steam generated from the constant temp. water 6 flows out of the spacing between the chamber 1 and the disk 3 but the outflow is impaired by the grooves 2 and the projecting parts 4 and, therefore, the decrease by the evaporation of the constant temp. water 6 is prevented. Condensed water 13 is the projecting parts 4 stagnate in the grooves 2 and return into the chamber 1 through a notches 12. The decrease by the evaporation of the constant temp. water 6 is prevented and a specified volume or above of the condensed water 13 accumulating in the groove 2 returns into the chamber 1 and, therefore, the need for exchanging the constant temp. water 6 during the analysis of a sample 7 is eliminated and the long-term operation is possible. |
