The purpose of the present invention is to provide an automatic analysis device capable of ensuring accuracy in a wide range of a pipetting amount without changing the rotation/vertical speed of a sampling arm and the aspiration speed of a pump. The automatic analysis device according to the present invention, which is an automatic analysis device for analyzing a target substance included in a sample, is characterized by comprising: a detection unit that analyzes the sample; and a probe that pipettes a liquid, wherein the probe changes the number of aspiration by which the liquid is aspirated into the probe according to the pipetting amount by which the probe pipettes the liquid.

A positioning system (1) that has a system main part (4), on which multiple working units (6) are arranged next to one another in the axial direction of a y-axis, said working units being linearly movable, thereby carrying out a working movement (8) in the axial direction of a z-axis. Each working unit (6) is paired with a dedicated drive unit (7) in order to be actuated, said drive unit having a stator (23) attached to the system main part (4) and an output element (24) drivingly connected to the working unit (6) via a coupling section (26). The stators (23) are distributed into multiple stator rows (58) which are aligned in the axial direction of the y-axis and are arranged one behind the other in the axial direction of the x-axis, wherein the stators (23) of each pair of adjacent stator rows (58) are offset to one another with a mutual overlap in the axial direction of the y-axis.

An automatic analyzer capable of confirming the amount of sample aspirated by a sample dispensing unit is provided.

An automatic analyzer that analyzes a sample 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.

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.

In blood clotting tests, a reagent is mixed with a sample and a blood clotting reaction is initiated. The time from initiation until the reaction is complete is not fixed. As a result, during analysis, whether or not the blood clotting reaction is complete is judged at fixed intervals based on the measured amount of scattered light. Therefore, time is wasted and analysis cannot be conducted efficiently if the blood clotting reaction reaches completion more quickly than predicted. Accordingly, the automatic analysis device and method takes this problem into consideration. When information about a plurality of samples is entered, the device compares the predicted reaction time length of each requested analysis item for the plurality of samples, determines an analysis sequence to carry out the analysis for each item in order from longest to shortest, and carries out the analysis on the basis of the determined analysis sequence.

A sample analysis support apparatus includes a sample region in which a sample is to be disposed, a tip region in which a tip is to be disposed, a first operation unit capable of an operation on the sample using the tip, the tip being attachable to and detachable from the first operation unit, a second operation unit capable of an operation on the sample using the tip, the tip being attachable to and detachable from the second operation unit, a transport unit configured to support each of the first operation unit and the second operation unit moveably between the tip region and the sample region, and a movement controller capable of controlling the transport unit to move each of the first operation unit and the second operation unit between the tip region and the sample region.

There is provided a receptacle carrier unit and automated analyzer capable of suppressing generation of temperature nonuniformities among liquid aliquots received in plural receptacles without increasing the parts count. The receptacle carrier unit has a turntable, a turntable drive, a cool box, a cooling portion, and a control section. The control section controls the turntable drive, based on the number and installation locations of the receptacles installed in the cool box and on temperature distribution information, to homogenize the effects that the individual receptacles receive from the cool box.

Aspects of the present disclosure relate to a method and/or a device for carrying out chemical, biochemical and/or immunochemical analyses of liquid samples, which are present in a sample store of an automatic analyzer, with the aid of liquid reagents which are present in at least one reagent store of the analyzer. In one example embodiment, the automatic analyzer includes cuvettes, a first pipettor, a device with an optical measurement unit, a device for heterogenous immunoassays, a cuvette washing unit, a needle washing unit, a temperature control unit.
