The present invention relates to methods, devices and systems for associating assay information with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system includes a reader adapted to read/erase/write information from/to an assay consumable identifier associated with the assay consumable. Various types of assay information are described, as well as methods of using such information in the conduct of an assay by an assay system.

A receptacle holder for supporting at least one fluid-containing receptacle includes a body and an RFID transponder. The body includes an electrically conductive portion defining a first recess configured to receive at least a first fluid-containing receptacle, and an electrically non-conductive portion attached to the electrically conductive portion. The RFID transponder is disposed on the electrically non-conductive portion of the body, and stores information about the receptacle holder. The receptacle holder can also include the first fluid-containing receptacle received within the first recess.

Systems and techniques for collecting and analyzing breath samples to detect one or more target analytes are disclosed.

The present invention relates to methods for the analysis of nucleic acids present in biological samples, and more specifically to normalize a high resolution melt curve to assist in the identification of one or more properties of the nucleic acids. The present invention provides methods and systems that incorporate a background identification algorithm according to invention principles using raw melt curve data to identify reactions that are unrelated actual DNA melt reactions. Furthermore, a web-based application for analyzing experimental data is provided. The raw experimental data obtained from a variety of instruments is processed and analyzed on a server and presented to a user through a user interface (UI).

An assembly for storing sample processing consumables can include a cover and a tray. The cover defines a cover cavity. The tray defines a first plurality of wells. The tray includes a first portion received within the cover cavity such that a press fit is formed between a first tray surface of the first portion of the tray and a first cover surface of the cover defining the cover cavity, thereby releasably coupling the cover to the tray. Each of the first plurality of wells contains a sample processing consumable. The assembly can be used to load sample processing consumables into a sample processing instrument.

Tissue sample cassettes for receiving tissue samples include an upper tray including compartments separated by dividers, a lower tray coupled to the upper tray and having a central recess, and an absorbent material located in the recess of the lower tray. Related systems and methods for automated gross processing of tissue samples are also disclosed.

A purpose is to provide a monitoring system to monitor whether there is a substance to be monitored in the air, and a detecting device used in the monitoring system. The monitoring system includes a detecting device, an analyzing device, and an abnormality notification system. The detecting device determines whether the air is in an abnormal state on the basis of an output signal from an abnormality detection sensor, pours liquid to be inspected, into which the air is sucked and liquefied, into a previously-installed reagent container when determining the abnormal state, generates mixed liquid in which a reactant in the reagent container and the poured liquid to be inspected are mixed, and drops the generated mixed liquid to an electrode of the analyzing device. The analyzing device determines existence/non-existence of a substance to be monitored on the basis of the mixed liquid dropped to the electrode, and gives a predetermined notification to the abnormality notification system when determining that there is the substance to be monitored. The abnormality notification system gives a predetermined notification when receiving the notification from the analyzing device.

An assembly for storing sample processing consumables that includes a cover and a tray. The cover includes a flexible panel and a cover wall that extends downward from the perimeter of the panel, where the panel and the cover wall define a cavity. The tray has a top surface that defines a plurality of wells and a side surface that extends downward from the perimeter of the top surface. The panel is situated adjacent the top surface of the tray, where a first portion of the tray is received within the cover cavity, such that a press fit is formed between the side surface of the tray and an inner surface of the cover wall, thereby releasably coupling the cover to the tray. At least a portion of the wells contain a sample processing consumable, and the cover is configured to be decoupled from the tray by applying a force to the panel to overcome the press fit.

A microfluidic system includes a microfluidic cartridge and a detector assembly. The microfluidic cartridge includes a first and second side and at least one flow channel and an inlet to flow channel(s) for feeding a liquid sample, the flow channel(s) includes a plurality of first optical detection sites. The detector assembly includes a slot. The detector assembly and the microfluidic cartridge are constructed such that when the microfluidic cartridge is inserted to a first predetermined position into the slot, one of the first optical detection sites of the microfluidic cartridge is positioned in the beam path of the first light source, and when the cartridge is inserted to a second predetermined position into the slot, another one of the first optical detection sites of the microfluidic cartridge is positioned in the beam path of the first light source.
