Abstract

According to an embodiment of the disclosure, the analyzer includes a reagent driving disk that accommodates a reagent configured for analysis and that transports the reagent to a desired position, and a fixed disk that has a reagent stand-by position in which to make a reagent container containing the reagent, temporarily stand by, and a magnetic particles stirring position for stirring magnetic particles. A portion of the reagent stand-by position is constituted by a loading system. A reagent container moving unit moves reagent containers containing the reagent, between the reagent driving unit and the fixed disk, according to analytical request status. Providing in a part of the fixed disk the loading system constructed so that reagent containers containing the reagent can be mounted therein during operation enables changing of reagent containers, irrespective of an operational status of the reagent driving disk, and the system to having cold-storage functionality.
