The flow cell is composed of a cell block and a cell holder. The cell block is light transmittable and is provided with a plurality of cells communicated with each other and mutually different in optical path length and an inlet and an outlet communicated with the cell. The plurality of cells include a short optical path length cell having an optical path length of 100 m or less. The short optical path length cell is constituted by a groove formed on an inner joining surface of a plurality of laminated light transmitting substrates. The optical path length of the short optical path length cell is defined by a depth of the groove. The cell holder is configured to accommodate the cell block therein, and is provided with an incident window for allowing light to enter the cell block and an emission window for emitting the light transmitted through the cell block.

A fluid analytical device comprising: a disc (1) rotatable around an axis (2), the disc (1) comprising: a first layer, the first layer comprising: a disc; and at least one microfluidic channel (6) in the disc partially extending from the disc axis (2) to the disc edge; a second layer, the second layer comprising: a disc of substantially the same diameter as the disc of the first layer; and at least one through input port (3) and one through measurement port (4) pair, the input port (3) located near the disc axis (2) and the measurement port (4) located distal from the disc axis (2); wherein when assembled each of the at least one input port (3) and measurement port (4) pair are aligned with one of the at least one microfluidic channels (6); and a disc spinning mechanism (12); a controller (13) for controlling the disc spinning mechanism (12); and a microscope (11) for analysing the fluid through the measurement ports (4) in the rotatable disc (1).

A blood glucose meter (component measurement apparatus) includes a measurement chip, and an apparatus main body including an insertion hole. The measurement chip includes a pair of plate pieces, a spacer arranged between the pair of plate pieces, and a cavity that can retain blood. A pair of wall portions of the insertion hole, facing each other at a measurement unit and in the vicinity of the measurement unit, is separated from each other with a width smaller than a thickness of the measurement chip in a lamination direction. The spacer elastically deforms by a state in which the pair of plate pieces is pressed by the pair of wall portions and defines a width of the cavity.

Methods are provided for the automated detection of micro-objects in a microfluidic device. In addition, methods are provided for repositioning micro-objects in a microfluidic device. In addition, methods are provided for separating micro-objects in a spatial region of the microfluidic device.

Disclosed herein are a microchip provided with a titanium oxide film between a glass substrate and a metal thin film; and a method for forming the metal thin film and the titanium oxide film on the glass substrate of the microchip. The microchip has a second microchip substrate that has the metal thin film inside a channel, and the titanium oxide film, which has a low extinction coefficient, is provided as a buffer layer between the substrate and the metal thin film such as a gold film.

A microfluidic chip is disclosed herein. In an embodiment, the microfluidic chip includes a body including at least one microfluidic pathway configured to receive a fluid sample, the at least one microfluidic pathway including a coating configured to reduce fluid diffusion and seal a surface of the at least one microfluidic pathway, and a heating device located on the body and forming a heating zone within a portion of the at least one microfluidic pathway.

One example of a flow cell includes a base support and a multi-layer stack positioned over the base support. The multi-layer stack includes a resin layer positioned over the base support; and a hydrophobic layer positioned over the resin layer. A depression is defined in the multi-layer stack through the hydrophobic material and through a portion of the resin.

The present invention relates to the field of biological sample testing technology, and in particular, to a biological sample reaction vessel. A reagent storage portion and a push rod movable relative to the reagent storage portion are packaged in the reaction vessel; the reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with an external device to separate the sealing element from the reagent storage portion. In this application, the reagent storage portion and the push rod are both packaged in the biological sample reaction vessel, and in reaction, the biological sample reaction vessel only needs to cooperate with a test cassette. With one operation, that is, inserting the biological sample reaction vessel into the external device, the reagent in the reagent storage portion can be released rapidly.
