Abstract
An automatic chemical analyzer includes a rotary disc which is intermittently driven for rotation in a given direction and which is provided with a plurality of holders, each of which receives a reaction tube therein. The reaction tubes are disposed to move through an annular channel of a thermostat liquid vessel which maintains first reagent and a liquid sample to be examined, both injected into a reaction tube, at a given temperature. Second reagent is heated to a predetermined temperature before it is injected into the reaction tube. After the injection, the liquids are agitated to mix them together, and the resulting reaction solution is then subject to a colorimetric determination by an optical measuring instrument. Subsequently, the reaction solution is discarded, and rinse water which is previously heated to a given temperature is supplied to the tube for cleaning it.
