ABSTRACT:
There is disclosed an automatic biochemical analyzer having a sample turntable and a reaction turntable. Plural sample containers for holding samples are arrayed on the sample turntable. Plural reaction containers are arrayed on the reaction turntable. A sampling pipette draws in a sample from some sampling container and injects the sample into some reaction container. A reagent pipette draws in some reagent from some reagent container and injects the reagent into the same reaction container. The resulting mixture is stirred by a stirring device. Produced reaction products are detected by a detector. Let N be the number of the reaction containers on the reaction turntable. The reaction turntable is rotated in M pitches in one step. Note that M and N do not have any common factor. First and second injecting positions adjacent to each other are established as positions where the reagent pipette can inject a reagent into the reaction container in position. First and second stirring positions adjacent to each other are established as positions where the stirring device can stir liquids in the reaction container in position. The stirring device can be moved between the first and second stirring positions. Thus, one reagent pipette can be used for two kinds of reagents. Also, one stirring device can be used for two kinds of reagents.
