A microfluidic device for forming droplets includes at least one ferrofluid reservoir disposed in the microfluidic device and containing a ferrofluid therein. The microfluidic device includes a continuous-phase reservoir disposed in the microfluidic device and containing an oil phase therein and one or more microfluidic channels connecting between the at least one ferrofluid reservoir and the continuous-phase reservoir, the continuous-phase reservoir comprising a step region having an increased height as compared to a height of the one or more microfluidic channels. To form droplets an externally applied magnetic field is applied to the device to pull the ferrofluid into the continuous-phase reservoir, whereby droplets are formed at step region.

The purpose of the present invention is to provide an automatic analysis system which, even when a large number of quality control samples is necessary, reduces the time necessary for quality control. To this end, this automatic analysis system is provided with multiple analysis devices (190), a conveyance unit (120) to which the analysis devices (190) are connected, and an operation unit (101) which operates the conveyance unit (120) to convey samples to the analysis device (190), wherein the automatic analysis system has a common storage cabinet (210) for storing the quality control samples that can be supplied to the multiple analysis devices (190), and in accordance with a rule registered in advance for each of the multiple analysis devices (190), the operation unit (101) operates the storage cabinet (210) to automatically convey a quality control sample to an analysis device (190).

Provided is an automatic analyzer in which a lid of a reagent vessel does not hinder the dispensing of the reagent.

An automatic analyzer for analyzing a specimen includes a reagent dispensing unit for dispensing a reagent from a reagent bottle in which a plurality of reagent vessels storing reagents used for the analysis of the specimen are arranged in one direction, and a reagent rack in which reagent bottles are stored, in which the reagent rack includes a lid opening unit for opening a lid corresponding to an upward opening of the reagent vessel along an arrangement direction of the reagent vessels, and a lid fixing unit for fixing the lid to the outside of a path in which the reagent dispensing unit is inserted into the opening.

An automatic analyzer includes a control unit 7d that, when an accuracy control sample is put in after input of a standard sample, requests measurement of the input accuracy control sample on the same measurement item as a requested measurement item for the standard sample; and a selection screen 201 or 501 that enables selection of measurement timing of the accuracy control sample on the same item as the requested measurement item for the standard sample. The control unit 7d starts measurement of the accuracy control sample when the timing selected on the selection screen 201 or 501 is reached. This reduces consumption of the standard sample and reagent as compared with before and provides an automatic analyzer that can improve analysis throughput.

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 separating apparatus of biosubstance and a separating method of the same are provided. The separating method includes: providing a controller to select a positive separation process or a negative separation process to execute according to types of target biosubstances; providing a pipette pump to inject a first magnetic bead reagent or a second magnetic bead reagent into a sample according to the selected separation process, such that first immunomagnetic beads of the first magnetic bead reagent or second immunomagnetic beads of the second magnetic bead reagent are used for binding to the target biosubstances; providing a magnetic separation rack to enrich the target biosubstances so as to separate the target biosubstances and non-target biosubstances; and providing the pipette pump to separate the target biosubstances and the non-target biosubstances.

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 analyzer includes: a plurality of dispensing units; and a plurality of pump units connected to the respective dispensing units. Each of the plurality of pump units includes: a syringe tube that has a liquid port at one end and an opening at another end; a syringe base that is attached to the opening at the other end of the syringe tube; a plunger that penetrates the syringe base and whose tip end is inserted inside the syringe tube; a seal piece that is configured to seal a gap between the plunger and the syringe base; an actuator; and a power transmission mechanism that connects the actuator and the plunger. Each plunger of the plurality of pump units has an individually set diameter and a different thickness. At least one of the syringe base and the syringe tube represents the diameter of the corresponding plunger in appearance.
