An automatic analyzer (100) includes: a storage unit (21b) that stores various parameters of the automatic analyzer (100) in association with each of elevations used in the automatic analyzers (100), the parameters being optimized for each of the elevations; an input unit (21d) that acquires information of an elevation at which the automatic analyzer (100) is provided; and a controller (21a) that reads the parameters stored in the storage unit (21b) and sets the read parameters to the automatic analyzer (100) based on the elevation acquired by the input unit (21d). As a result, various parameters can be easily adjusted according to a usage environment of the device.

There is provided a dispensing unit capable of alleviating the load on a dispensing unit and other components at the time of a collision while maintaining the vibration-suppressing function. Also, an automated analyzer having this dispensing unit is provided. The dispensing unit has a dispensing probe, a drive mechanism, an arm member, a first probe holder, a second probe holder, a first support spring, second support springs, and vibration dampers. The second probe holder is supported to the first probe holder so as to be movable vertically and holds the dispensing probe. The second support springs bias the second probe holder against the first probe holder and in combination have a spring constant smaller than that of the first support spring. The vibration dampers are bridged from the arm member to the second probe holder.

A maintenance reservoir for a digital dispense system. The maintenance reservoir includes an elongate trough disposed in a micro-well plate holder for holding fluid dispensed from a fluid droplet ejection head of a fluid droplet cartridge in the digital dispense system. The maintenance reservoir is disposed in the micro-well plate holder on at least one side of a micro-well plate and includes a position indicator to signify if the elongate trough is present or absent from the micro-well plate holder.

Methods of transferring material from a first device having an array of microwells to a second device is provided. In some examples, the first device and the second device are moved together toward a stopper plate and impinge on the stopper plate. In other examples, the first device and the second device are kept stationary and an impinging device is impacted on a mounting structure enclosing the first and second devices, causing material transfer from the microwells of the first device to the second device. Apparatus for carrying out the transfer of material is also disclosed.

Included are: a main body including an installation part in which a cartridge housing a liquid for treating a test substance contained in a specimen is installed and a detector configured to detect the test substance treated with the liquid within the cartridge installed in the installation part; a lid part arranged rotatably on the main body about a shaft so as to open and close the installation part; a biasing part biasing the lid part in an opening direction; and a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part.

The invention relates to a sample acquiring device holder (3) for a housing (2) of an analysis apparatus (1). The sample acquiring device holder (3) may comprise an activating element (5) and a reception recess (11) for receiving a sample acquiring device (4). A first portion (10) of the activating element (5) may protrude into the reception recess (11), if the activating element (5) is in a non-activating position. The activating element (5) may be adapted to be moved into an activating position by the sample acquiring device (4), if the sample acquiring device (4) is inserted into an intended measurement position within the reception recess (11). The activating element (5) may be adapted to activate a measurement triggering element (15), if the activating element (5) is in its activating position, such that the measurement triggering element (15) activates a measurement of the analysis apparatus (1).

A tube guidance means (36) for a laboratory automation system (10) comprises a plate (40) with a guide opening (38); wherein the guide opening (38) has two partial openings (42) which are separated by a land (46) and which are connected by a slot (44); and wherein the partial openings (42) have cutouts (54) for guiding a tube (32), the cutouts (54) being located opposite each other on edges (52) which face away from each other.

A sample injection device (100) includes a tubular suction and discharge unit (23) configured to suction a liquid sample (S), contain the sample therein, and discharge the suctioned sample, and at least a portion of an inner wall (23a) of the suction and discharge unit, the portion having the sample contained therewithin, is subjected to a surface treatment (V) to increase an interfacial tension (F) that acts between the inner wall and the sample.

Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

A specimen conveyance system and a specimen conveyance method are realized, in which a conveyance route of a specimen can be reset even when information about an additional request is received after loading of the specimen. When an abnormality occurs in the analysis result, a notification of the abnormality is sent to an operation control unit and a host computer through a communication cable and information about the additional request for changing the conveyance route is created. After the specimen is conveyed from the analysis device to the transfer machine, information about the additional request is checked at a destination determination point, and the conveyance route is changed according to the additional request. Accordingly, the specimen container can be conveyed to the appropriate analysis device without being returned to the storage unit once, and thus the specimen analysis time can be reduced.
