The conveyance mechanism 27, the sample dispensing mechanisms 21, 22, and the pH measurement mechanism 34 are disposed such that the dispensing of the sample by the pH measurement mechanism 34 for pH measurement, or pH measurement, is performed after the dispensing of the sample by the sample dispensing mechanisms 21, 22.

When the consumable is to be conveyed by a reagent gripping mechanism 110 and a reagent conveyance mechanism 111 during analysis of the sample, a control unit operates such that an operation of a device to access the storage unit is stopped, and makes a plan of operation of the reagent gripping mechanism 110 and a reagent conveyance mechanism 111 such that the consumable is conveyed also at a timing at which an operation of the device is stopped, the timing inevitably occurring after the former stop. Accordingly, an automatic analyzer is provided in which occurrence of an unnecessary empty cycle caused when plural consumables are replaced during analysis can be suppressed compared to a prior art.

Provided is an automatic analysis device that shortens the confirmation time for calibration or precision management. This automatic analysis system includes an analysis device configured to perform an analysis for deriving a property of a specimen on the basis of the relative relationship between a measured value of a standard specimen for which the property is known and a measured value of the specimen, and a display device that displays information about calibration or precision management carried out on the analysis device using the standard specimen, the system being characterized in that the display device displays: a request list including request information about request for the calibration and/or the precision management; and/or a preparation list that displays, in an empty manner, a field of the standard specimen that corresponds to an in-rack position number where the standard sample is not to be placed, as preparation information about preparation of the standard specimen to be used, in accordance with the request, in the calibration and/or the precision management.

Provided is a reagent cooler that prevents occurrence of condensation and further uniforms a temperature in the cooler with low power consumption and a simple structure. The reagent cooler includes a refrigerant pipe that is disposed inside an outer wall of the reagent cooler 103 and circulates a refrigerant inside the outer wall; a blowing pipe 109 that is disposed inside the outer wall and guides outside air existing outside the reagent cooler to inside of the reagent cooler; and a blowing unit 114 that is disposed at the blowing pipe and diffuses the outside air into the inside of the reagent cooler through the blowing pipe. With the outside air cooled by the outer wall and taken into the inside of the reagent cooler, the reagent cooler is positively pressurized and the internal temperature is made uniform.
