ABSTRACT:
An automatic processor for analyzing reaction solutions has a large number of reaction vessels arranged in a circle on a disk, a disk driver for circulating the reaction vessels successively to pass through a sample pouring position, a reagent adding position and an analyzing position in order, sample pouring pipet nozzle for pouring a sample into each of the reaction chambers at the sample pouring position, reagent adding pipet nozzle for adding a reagent into each of the reaction chambers at the reagent adding position, and analyzer for analyzing a reaction solution in each of the reaction vessels at the analyzing position. A large number of reaction vessels are divided into a plurality of reaction vessel groups each of which has a plurality of reaction vessels. The disk driver circulates each of the reaction vessel groups in a predetermined time in accordance with the reaction times of the reaction solutions in the reaction vessels of the same reaction vessel group.
