Provided is an automatic analyzer that can perform a reagent preparation/disposal operation comfortably and smoothly as when printing a reagent list such as a reagent preparation/disposal list on paper even without printing the reagent list. The automatic analyzer that performs analysis using a sample and a reagent, the automatic analyzer including: a storage unit that stores reagent information related to a reagent remaining amount or a reagent expiration date of each of reagent containers; and a display unit that displays a reagent list in which reminder information that gives a reminder to an operator is assigned to each of setting positions of the reagent containers based on the reagent information stored in the storage unit. The reagent managing unit updates display of the reagent list such that a reagent container selected by the operator is visually identifiable while the reagent list is displayed.

This disclosure relates to a method and an apparatus for monitoring a concentration of a reagent, an electronic device, a computer-readable storage medium. The method includes: acquiring a first concentration of a current reagent measured during filling of the current reagent with a preset concentration; acquiring a current volume of carryover determined in filling and draining a previous reagent; acquiring a second concentration of the current reagent measured during draining of the current reagent and determining, based on the preset concentration, a volume of the reagent bottle and the current volume of carryover, a third concentration of the current reagent; updating the current volume of carryover based on the first concentration, the second concentration and the volume of the reagent bottle; and when the third concentration is less than a preset concentration limit, reminding to replace the current reagent and/or refreshing the current reagent with a higher concentrated reagent.

The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

An automated laboratory system for processing biological samples in a batch type manner is disclosed. In one embodiment, the system may receive assay instructions for biological samples processing among a plurality of devices. The devices may include a pre-analytical instrument and one or more analysis systems. The system may include an orchestration core application for determining an order of performance for the assays ordered for the samples.

An object of the present invention is to provide an automatic analyzer that can decrease the frequency of cleaning as compared to the past by suppressing breeding of bacteria and the like in a buffer tank as compared to the past and can reduce maintenance work time of an operator. Provided is an automatic analyzer comprising: an analysis module 20 that analyzes a specimen; and a supply system that supplies a liquid to the analysis module 20, wherein the supply system includes: a buffer tank 3 that temporarily stores pure water supplied from a pure water production device 50 outside of the analyzer; a supply channel 7 through which the pure water in the buffer tank 3 is sent to the analysis module 20; a circulation water pump 4 that feeds the pure water in the buffer tank 3; a circulation channel 8 through which the pure water discharged from the circulation water pump 4 is returned to the buffer tank 3; a sterilization mechanism 5 that sterilizes the pure water in the supply system; and a control unit 30 that controls an operation of each device in the supply system.
