An automated analysis device has a reaction container constructed on a reaction disc, a reaction tank for immersing the reaction container in water, a water level sensor, a reagent probe that suctions/discharges a reagent to the reaction container, and a controller. In the reagent probe, a water detection unit that detects the presence of water is provided at a prescribed site, the reagent probe being capable of detecting the water level in the reaction tank. The controller detects the water level in the reaction tank in at least three locations (e.g., a first water level confirmation part, a second water level confirmation part, and a third water level confirmation part) by using the water level sensor and the reagent probe, and has a function for confirming the levelness of the reaction tank or an apparatus on which the reaction tank is installed.

A turntable mechanism, a cleaning device and a sample analyzer are provided. The turntable mechanism includes a turntable. A plurality of circles of placement part groups for placement of reaction vessels are formed on the turntable; all the placement part groups are disposed at intervals from inside to outside along a radial direction of the turntable; at least one circle of through hole group is formed between every two adjacent circles of the placement part groups; and all placement parts in each circle of the placement part group and all through holes in each circle of the through hole group are arranged at intervals along a circumferential direction of the turntable. Each circle of the placement part groups and the circles of the through hole groups are all disposed concentrically with the turntable.

Various embodiments include a system having a pipetting chamber, a set of pipettor cartridges docked in the pipetting chamber, a gantry system mounted on a ceiling within the pipetting chamber, the gantry system including at least one stationary track aligned in a first direction, and a movable track aligned in a second direction distinct from the first direction, the movable track coupled to the at least one stationary track, and a carrier configured to transport each of the set of pipettor cartridges to a pipetting location within the pipetting chamber, the carrier configured to move each pipettor cartridge in a third direction perpendicular to both the first and second directions.

Various embodiments of the present disclosure are directed to an automatic pipetting system for transferring liquid from dispensing vessels into at least one receiving vessel. In one example embodiment, the system includes a movable pipettor moveable along an x-direction. The pipettor including an arm including two beams and a base structure, and at least one pipetting module. The base structure is movable in the x-direction, and is coupled to the two beams. The two beams oriented parallel to one another and project horizontally in the y-direction. The at least one pipetting module is moveable along each of the two beams in a y-direction and includes at least one hollow needle lowerable in to the dispensing vessels and the receiving vessels. Wherein the at least one pipetting modules move independently past one another on mutually facing longitudinal sides of said beams.

An automatic analyzer is provided wherein degree of freedom in arrangement of a dispensing mechanism and of a unit provided below the dispensing mechanism is improved. The automatic analyzer comprising a dispensing mechanism driving a probe for a specimen or a reagent, wherein the automatic analyzer comprises an arm of two degrees of freedom supporting the probe, a first shaft and a second shaft that support the arm and transmit power to the arm, and a motor that gives power allowing the first and second shafts to be rotated and vertically moved, the second shaft being divided in an axial direction and having different diameters and, at the time of lowering the arm by the power of the motor, divided one of the second shaft being housed inside the other, whereby the second shaft is shortened.

An automatic analyzer capable of confirming the amount of sample aspirated by a sample dispensing unit is provided. The automatic analyzer includes an incubator which holds a reaction container in which a liquid mixture of the sample and a reagent is accommodated, a sample dispensing unit which dispenses the sample by aspirating the sample from a sample container in which the sample is accommodated and storing the aspirated sample in a storage portion and then discharging the sample to the reaction container, and a measurement portion which measures the amount of sample in the storage portion on the basis of a detected signal obtained by detecting light passing through the storage portion while irradiating the storage portion with light.

An automatic assaying system having a multiplex pipette cartridge section in which pipette cartridges are docked. At least one pipette cartridge has a different pipetting characteristic from another corresponding pipette cartridge, the different pipetting characteristic being selectable from a number of different pipetting characteristics. A multiplexing work item holder has an array of work item holder docks that dock corresponding work item holders selectable from pipette trays and pipette tip set racks that define the selectable different pipetting characteristic. One or more of the work item holder docks are indexed to selectably multiplex both the different interchangeable pipette trays and the at least one pipette set rack. A carrier moves the pipette cartridge or a work item holder carriage and a controller selects the at least one pipette tip set rack corresponding to a work item holder dock so as to effect automatic selection of the different pipetting characteristic.
