Abstract:
1. A sample analysis device comprising: a thermostatic chamber which holds a liquid; a controller which controls the temperatures of the liquid so that the liquid comprises a constant temperature liquid which is held in the thermostatic chamber; a plurality of cells which contain a reaction solution; a cell disk which holds the plurality of cells being immersed in the constant temperature liquid inside the thermostatic chamber; a drive part which rotationally drives the cell disk; and a holder which holds a light emission unit for generating light to be radiated to the cell and a light receiving element for detecting the light having passed through the cell, characterized in that the holder is immersed in the constant temperature liquid and placed inside the thermostatic chamber, wherein the light emission unit and the light receiving element are integrally built into a part of the holder that is immersed in the constant temperature liquid, and wherein the holder includes a first vertical arm having a flat first surface and a second vertical arm having a flat second surface, the first and second surfaces facing each other with the cell containing the reaction solution positioned therebetween, and wherein the flat first surface adjoins a first side surface of the first vertical arm and the flat second surface adjoins a second side surface of the second vertical arm, the first and second side surfaces being curved surfaces.
