The present disclosure provides a consumable box automatic transmission device. The consumable box automatic transmission device includes a consumable box storage mechanism, configured to load and store consumable boxes, and a consumable box lifting mechanism, located above the consumable box storage mechanism; the consumable box lifting mechanism is able to lift the consumable boxes; the consumable box storage mechanism and the consumable box lifting mechanism is able to respectively store and transmit the consumable boxes; the consumable box storage mechanism is able to transmit the consumable boxes to the bottom of the consumable box lifting mechanism; and the consumable box lifting mechanism receives the consumable boxes at a bottom and lifts the consumable boxes to a top layer of the consumable box lifting mechanism. In this way, parallel consumable box transmission can be achieved, and continuous consumable box conveyance is achieved, thereby reducing manual care or frequent manual operation.

The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such information in the conduct of an assay by an assay system.

An automatic analysis device has a plurality of types of photometers having different quantitative ranges, and an analysis control unit for quantifying the desired component in specimens based on measurement values of one or more photometers selected from among the plurality of types of photometers. The analysis control unit: sets a switching region in an overlap region of respective quantitative ranges of the plurality of types of photometers, said switching region having a greater width than does the variation in quantitative values of the desired component based on the measurement values of photometers having the same specimen; compares the quantitative value of a quantitative range portion that corresponds to the switching region and the quantitative values of the desired component based on the measurement values of the photometers; and selects a photometer to be used in quantitative output of the desired component from among the plurality of types of photometers.

Actuation systems and methods for use with flow cells. An example apparatus includes a flow cell assembly including a flow cell including at least one channel, a flow cell inlet, and a flow cell outlet. The flow cell assembly includes a gasket assembly operatively fluidically coupled to the flow cell and having a flow cell inlet gasket and a flow cell outlet gasket. The flow cell inlet gasket having a through bore and being fluidically coupled to the flow cell inlet. The flow cell outlet gasket having a through bore and being fluidically coupled to the flow cell outlet. The apparatus includes a reagent cartridge adapted to receive the flow cell assembly and including a pair of reagent cartridge ports adapted to be fluidly coupled to the flow cell inlet gasket and the flow cell outlet gasket.

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.

This sample rack conveying apparatus is provided with a pusher unit, a linear motion guide, and a conveyance drive mechanism. The pusher unit has a base portion, a moving member, and a base-side guide. The base portion is supported by the linear motion guide so as to be movable in a first guide direction. The moving member is provided with a pusher that pushes a sample rack. The base-side guide supports the moving member such that the moving member is movable in a second guide direction that crosses the first guide direction.

A tube rack transfer device for transferring racks is presented. A first rail extends in a first horizontal direction and a second rail extends in a second horizontal direction orthogonal to the first direction. The second rail moves along the first rail and comprising a transfer head movable along the second rail. The transfer head comprises a control pin to be coupled with one of: an input pusher, translatable in the second direction, for transferring a rack from a carrier to a sampling area of an analyzer; an output pusher for transferring a rack from the sampling area to a carrier; a rack for transferring the rack between different carriers and/or between different positions of the same carrier. An in-vitro diagnostic instrument comprises an analyzer for carrying out tests on biological samples, a sample unit for inputting/outputting racks, a sampling area for withdrawing samples from tubes, and a transfer device.

A method for measuring optical signal detector performance that includes directing light emitted from an optical signal detector onto a first non-fluorescent surface portion in a first detection zone of the optical signal detector. A first characteristic of light detected by a first sensor of the first optical signal detector is measured while the first non-fluorescent surface portion is in the first detection zone of the optical signal detector. Light emitted from the optical signal detector is directed into a first void in the first detection zone of the optical signal detector. A second characteristic of light detected by the first sensor of the optical signal detector is measured while the first void is in the first detection zone of the optical signal detector. And an operational performance status of the optical signal detector is determined based on at least one of the first characteristic and the second characteristic.
