According to one embodiment, a reagent storage include a placement table, a housing, a cover, and a fan. The placement table on which a plurality of reagent containers are placed. The housing configured to contain the placement table. The cover having a probe hole through which a probe is inserted and configured to cover an opening of the housing. The fan configured to send air in a first space defined by an inner bottom of the housing and the placement table into a second space defined by the cover and the placement table and to exhaust the air in the second space through the probe hole.

A system for automated microorganism identification and antibiotic susceptibility testing comprising a reagent cartridge, a reagent stage, a cassette, a cassette, stage, a pipettor assembly, an optical detection system, and a controller is disclosed. The system is designed to dynamically adjust motor idle torque to control heat load and employs a fast focus process for determining the true focus position of an individual microorganism. The system also may quantify the relative abundance of viable microorganisms in a sample using dynamic dilution, and facilitate growth of microorganisms in customized media for rapid, accurate antimicrobial susceptibility testing.

Provided are an automatic analysis device and a maintenance support system which prevent a failure that occurs between regular inspection periods to thereby reduce the downtime of the automatic analysis device. A maintenance support system acquires, from each of a plurality of automatic analysis devices (100), pulse information transmitted from the automatic analysis device (100) provided with a mechanism which is driven by a pulse motor, and a transmission means which transmits pulse information including tow among a driving pulse value for driving the pulse motor, a consumed pulse amount that is a pulse amount consumed when the pulse motor has actually been driven, and a remaining pulse amount obtained by subtracting the consumed pulse amount from the driving pulse value, and stores at least the consumed pulse amount.

Provided are an automatic analyzer that can decrease waiting time for a user and reduce running costs as compared with in the past and an operation method for the automatic analyzer. The analyzer includes: a first mechanism group that is used only in analysis for biochemical items; a second mechanism group that is used only in analysis for immunological items; a common mechanism group that is used in analysis for both biochemical items and immunological items; and a control part that activates the second mechanism group and common mechanism group without activating the first mechanism group when analysis for biochemical items is not required, and activates the first mechanism group and common mechanism group without activating the second mechanism group when analysis for immunological items is not required.

Provided is an automatic analysis device having an incubation function. An example of the automatic analysis device includes: a reaction vessel storage section where a reaction vessel storage container that stores reaction vessels is installed; and a dispensing mechanism that dispenses specimens or reagents into a reaction vessel which was removed from the reaction vessel storage container. The reaction vessel storage section has a temperature-controlled area where at least a portion of the storage section is adjusted to a prescribed temperature. The reaction vessel into which a specimen or a reagent is dispensed by the dispensing mechanism is placed in a reaction vessel storage container installed in the temperature-controlled area for a prescribed period.

A positioning system for a sample analysis device is disclosed. The positioning system comprises (1) a carousel comprising a platform and a sample loading tray mounted on the platform, and (2) a stage comprising a positioning system for positioning the carousel under the optical path of an imaging system. The sample loading tray is configured for holding a cartridge comprising one or more lateral flow cells (LFCs).
