Analyzer

An analyzer comprising:

• a reagent suction unit for suctioning reagent from a reagent container;
• an analyzing unit for analyzing an analyzing specimen comprising a sample and the reagent;
• a container holder configured to hold a plurality of reagent containers in a circular ring form;
• a container raising and lowering unit configured for executing a mounting operation of mounting the reagent container on the container holder by lowering the reagent container from a mounting position at which a reagent container is mounted on the container raising and lowering unit, and a raising operation of raising the reagent container to a retrieving position above the container holder, the retrieving position being the same as the mounting position;
• and
• a rotation unit configured for moving at least one of the plurality of reagent containers to a raise waiting position below the retrieving position, at which the container raising and lowering unit raises the reagent container to the retrieving position, by rotating the plurality of reagent containers held by the container holder.

An analyzer comprising:

• a reagent suction unit for suctioning reagent from a reagent container;
• an analyzing unit for analyzing an analyzing specimen comprising a sample and the reagent;
• a container holder configured to hold a plurality of reagent containers;
• a mounting platform on which at least one of the plurality of reagent containers is mounted, wherein the container holder has an area through which the mounting platform passes in the up and down direction;
• and
• a driving source for moving the mounting platform to a first position, above the container holder, at which a reagent container is mounted on and retrieved from the mounting platform, and a second position, below the first position, at which a reagent container is held by the container holder.
