Abstract: It is necessary to dispose a plurality of units which have different target temperatures on an apparatus in a more integrated state in order to improve analysis performance and processing capacity per unit space of the apparatus. Therefore, it is necessary to mitigate influence of temperature exerted between units.It is possible to reduce the temperature influence exerted between the units and thus efficiently control temperature by properly disposing the units in the apparatus, based on the relationship between a use environment temperature of the apparatus and a target temperature of each unit and temperature accuracy required for the unit.

Abstract: An analyzer that has a simple configuration, that is inexpensive, that can improve safety, and that can inhibit proliferation of microorganisms using ultraviolet light is realized. A first electric power switch, a second electric power switch, and a third electric power switch are connected in series between an ultraviolet LED that irradiates an interior of a shared reagent storage container with ultraviolet light and a power supply that supplies electric power to the ultraviolet LED. The first electric power switch, the second electric power switch, and the third electric power switch are configured with two contact points and a connection section that connects and disconnects the two contact points. The first electric power switch is opened when a reagent storage door is opened, and the second electric power switch is opened in response to an action of extracting an ultraviolet irradiation section from a shared reagent storage container. The third electric power switch is opened when an amount of the reagent within the shared reagent storage container is equal to or smaller than a constant value. When one of the first electric power switch, the second electric power switch, and the third electric power switch is opened, supply of the electric power to the ultraviolet LED is intercepted.

Abstract: Provided are an automated analyzer for analyzing a substance contained in an unknown sample and a liquid reservoir, the analyzer and the reservoir being capable of saving users' operation without remarkably increasing the number of components. A flow path outlet of an overflow portion of the liquid reservoirs projects closer to the inner circumferential side of a drain flow path than to an inner circumferential surface side of an outer wall of the drain flow path serving as a destination to which liquid overflows. In addition, the flow path outlet projects so as to come into contact with an outer wall of the inner pipe. The flow path outlet of the overflow portion projects into the drain flow path so as to be located below an upper end of the outer wall of the drain flow path.

Abstract: An object is to provide an automatic analyzer that prevents an effect of various environmental changes on an equilibrium state of an immunological binding reaction. An automatic analyzer of an embodiment of the invention includes a B/F separation unit that executes a B/F separation step separating an unreacted component and a reacted component from a liquid in which a sample and a reagent are reacted, a detection unit that detects a reacted component in the liquid after the B/F separation step, and a temperature maintaining unit that maintains the B/F separation unit and the detection unit in substantially the same temperature environment.

Abstract: An amount of gas remaining within a fluid control valve is reduced according to a method for fixing the fluid control valve to achieve highly accurate trace dispensation by simply removing gas. The dispensing device has a discharge nozzle, a liquid feeding tube that is disposed so as to connect a reagent bottle in which a reagent is stored and the discharge nozzle and forms a reagent flow path, and a fluid control valve that is disposed on the liquid feeding tube route connecting the reagent bottle and the discharge nozzle. The fluid control valve is provided with a reagent flow path having a liquid inlet and a liquid outlet and a diaphragm valve provided in the middle of the flow path. The fluid control valve is disposed in an orientation such that the diaphragm valve is disposed at the bottom of the flow path of the fluid control valve.

Abstract: In a liquid stirring method, after a second liquid is discharged into a reaction container accommodating a first liquid from a dispensing probe provided with a dispensing tip at the leading end thereof, a mixture of the first liquid and second liquid in the container is stirred by being sucked out and discharged by the dispensing probe. The number of stirrings through sucking out and discharging is changed according to the total volume of the first liquid and second liquid. If the total volume of the first liquid and second liquid is below a preset threshold, sucking out and discharging is repeated for a prescribed number of times.

Abstract: The mixing of reagents with each other in the reagent storage flow paths of an automatic analyzer is suppressed before and after exchange of the reagents, which are capable of being replenished without stopping analysis. An exchangeable reagent container that accommodates a reagent is connected to a reagent storage flow path that stores a portion of the reagent. The reagent storage flow path has first and second flow paths in which the second flow path is branched from the first flow path. A reagent syringe applies a negative or a positive pressure to the first and second flow paths; and a valve controls the flow path through which the reagent is sent. As a result, the reagent supplied to a measurement portion at a predetermined timing is switched from the reagent container to the reagent storage flow path wherein the reagent can be supplied without stopping analysis.
