REAGENT STORAGE BOX AND AUTOMATIC ANALYZER INCLUDING REAGENT STORAGE BOX

PROBLEM TO BE SOLVED: To miniaturize an automatic analyzer and reduce the cost thereof by employing an efficient cooling system by air and to provide an automatic analyzer capable of improving the processing capability of the automatic analyzer adapting the cooling system and its reagent storage box.SOLUTION: The reagent storage box includes: a reagent rack storing a reagent used for analysis and holding a reagent bottle having a suction port; a circulation device for causing the air whose temperature is adjusted to circulate inside the reagent storage box; and a lid for the reagent storage box capable of covering the upper part of the reagent rack in opening and closing manner. The reagent rack installs the reagent bottles one by one and includes: a plurality of small sections having a wall covering at least five surfaces of the reagent bottle; a small section opening part for inserting the reagent bottle into the small section; a temperature adjustment opening part provided in the wall of the small section so that a temperature adjusting air for temperature-adjustment of the reagent bottle comes into contact with the wall surface of the reagent bottle. The reagent storage box lid prevents the temperature adjusting air from flowing into the opening part of the reagent bottle by closing the small section opening part.
