ABSTRACT:
An annular train of reaction vessels is formed on an intermittently rotatable turntable. In order to measure test items requiring different analysis times, samples and necessary reagents are successively added to the reaction vessels. The analysis times for the test items assigned to the respective reaction vessels are stored in association with positions or numbers of the reaction vessels. Reactions for the test items requiring different analysis times proceed in parallel on the turntable. The reaction vessel whose required analysis time has expired is renewed by a vessel renew device such as a washing device and prepared for receiving the next sample. When a sample for a test item requiring a short analysis time is added to a second reaction vessel after a sample for a test item requiring a long analysis time has been added to a first reaction vessel, the second reaction vessel is renewed earlier than the first reaction vessel.
