Abstract

PURPOSE:To enable colorimetric analysis to be performed while maintaining reaction liquid at a constant temperature by providing a heater in the portion of a light guide to be dipped in the reaction liquid. CONSTITUTION:A columnar body 2b made of transparent material of good light transmission efficiency is integrally bonded to a columnar body 2a of a hook shape composed of the same material so that one end face of the columnar body 2b opposes to the end face of the hook form part of the columnar body 2a by forming a spacing A. The end face on the hook shape portion of the columnar body 2a of the light guide of this colorimetric cell forms a reflecting face of 45 deg.. The cell 1 is dipped in the reaction liquid S of the reaction tube T in a thermostatic bath. The light from a light source 4 enters a photo detector 3 by passing the route of the columnar body 2b having a suitable taper face spacing A the hook portion of the columnar body 2a the other end of the columnar body 2a and its quantity of light is detected by the detector 3. At this time, the light guide is maintained as the same temperature as the liquid S by a heater 5 and there is no temperature drop of the drop of the liquid S entering the spacing A.
