Apparatus for analyzing a plurality of analysis items

摘要

A reagent containing device has an outer bottle holder and an inner bottle holder. The holders are rotated independently of each other. When an instruction for exchanging reagent bottles inside the reagent containing device is input, a first reagent bottle on the outer bottle holder and a second reagent bottle on the inner bottle holder relating to the same analysis item are positioned at an opening of a bottle exchanging area. Then the opening is opened by a sliding operation of a lid so that the first reagent and the second reagent bottles can be unloaded through the opening.
