Provided is a concentration monitoring system which allows continuous concentration monitoring of a processing tank. The concentration monitoring system is provided with a first cycle in which a sample of a processing liquid to which a chemical has been added is taken from a processing tank in which the processing liquid is stored and supplied to a concentration meter which measures the concentration of the chemical, a second cycle in which a chemical solution having a known concentration of the chemical is supplied to the concentration meter, and a control device which controls the first cycle to evaluate the concentration of the chemical in the processing tank on the basis of the concentration of the sample measured by the concentration meter and controls the second cycle to evaluate the precision of the concentration meter on the basis of the concentration of the chemical solution measured by the concentration meter.

An apparatus and a method for indicating a reagent status in a reagent bottle in a tissue processor and a tissue processor are provided. The apparatus includes a detector, a controller, and an indicator. The detector is configured to detect the reagent status. The controller is configured to generate a control signal based on the reagent status. The indicator is configured to generate a signal for indicating the reagent status based on the control signal. The apparatus may intuitively indicate the reagent status for an operator, such that the operator may replace the reagent timely and accurately, avoiding reagent replacement error.

Provided herein are instruments and cartridges for processing samples. The cartridges include fluidic circuits in which fluid movement can be regulated by diaphragm valves. In certain cartridges, deformable material providing a diaphragm contacts an interface in the instrument that actuates the diaphragm directly, without intervening actuation layer. Certain cartridges have a plurality of fluidic circuits and fluid distribution channels or pneumatic distribution channels configured to deliver fluids or pneumatic pressure to any of the fluidic circuits, selectively. Certain cartridges have compartments containing on-board reagents. Compartments can be closed by a film attached to a body the cartridge through a heat seal.

A method of operating a tissue processor for processing tissue samples is provided. The tissue processor includes at least one retort for receiving tissue samples, at least one container for storing a reagent, and at least one sensor arranged for fluid communication with one or both of the at least one container and the at least one retort for measuring a measured purity level of a reagent. The method includes the steps of conducting reagent from the at least one container or the at least one retort to the at least one sensor, automatically measuring, by means of the at least one sensor, a measured purity level of the reagent, checking whether the measured purity level meets a predetermined purity level of the reagent associated with the at least one container, and automatically determining, based on a result of checking, whether the reagent is suitable for processing tissue samples in the tissue processor. A tissue processor for processing tissue samples is also provided. A container is also provided for storing tissue samples for processing in a tissue processor.

Disclosed is a data management system configured to manage data regarding a specimen measurement system including a measurement unit configured to measure a specimen and control software configured to control the measurement unit, the data management system including: data management software configured to manage data regarding the measurement unit that operates under control by the control software; and an interface configured to allow application software capable of being added to the specimen measurement system, to utilize the data, wherein a function of the specimen measurement system is expanded by the application software added to the specimen measurement system.

Disclosed is a sample analysis system comprising a plurality of sample analyzers configured to analyze samples by using consumables, and a consumable manager configured to manage a replacement timing of the consumables in each of the sample analyzers, wherein the consumable manager comprises a controller, a storage, and an interface for an input and an output of information, wherein the controller is configured to obtain a usage record of the consumables from each of the sample analyzers and store the usage record in the storage, receive, via the interface, an input specifying a desired period among multiple periods of different lengths of time including (i) a period longer than a day and (ii) a period of a day or shorter, and provide, via the interface, information regarding a predicted replacement timing of the consumables during the desired period based on the usage record.

Presented herein are techniques for qualifying, checking and monitoring the use of diagnostic apparatuses and reagents, such as sequencing apparatuses and reagents, to ensure performance and quality of diagnostic methods. In one aspect, a system is provided for determining whether a sequencing run is a qualification run. The system includes a memory configured to store identifiers of sequencing apparatuses and an associated status, a network interface configured to communicate with a sequencing apparatus and a client terminal, and a processor configured to receive a report from the sequencing apparatus via the network interface for a sequencing run, and determine whether the sequencing run is designated as a qualification run.
