Abstract
The mixing of reagents with each other in the reagent storage flow paths of an automatic analyzer is suppressed before and after exchange of the reagents, which are capable of being replenished without stopping analysis. An exchangeable reagent container that accommodates a reagent is connected to a reagent storage flow path that stores a portion of the reagent. The reagent storage flow path has first and second flow paths in which the second flow path is branched from the first flow path. A reagent syringe applies a negative or a positive pressure to the first and second flow paths; and a valve controls the flow path through which the reagent is sent. As a result, the reagent supplied to a measurement portion at a predetermined timing is switched from the reagent container to the reagent storage flow path wherein the reagent can be supplied without stopping analysis.
