An analysis apparatus including a stage, an analysis device placed on the stage and including receiving sections which accommodate a sample and a reagent for biochemical reaction, and are communicated with one another through a flow path having an inlet and an outlet, a liquid introduction section which is connected to the inlet and supplies into the flow path the sample, the reagent, and an sealing liquid for sealing each of the receiving sections, and a waste liquid storage section which is connected to the outlet and stores as waste liquid an excess of the sample and the reagent and a part of the sealing liquid supplied to the flow path, an optical system which includes an objective lens, emits excitation light to the receiving sections and allows observation of fluorescence generated in the receiving sections by the excitation light, and a control unit that controls such that the sealing liquid and the excess of the sample and the reagent form an interface in the waste liquid storage section, and that the interface is formed at a distance not less than a fluorescence-obtainable distance from a bottom of the receiving sections.

Analysis devices, analysis kits, and analysis systems

A reaction container including a transparent base having a first surface having at least one region where recessed portions are formed and recessed from the first surface, and a cover member positioned such that the cover member forms a gap from the first surface inside the region and is welded to the transparent base outside the region. The cover member absorbs infrared light and transmits light having a wavelength within a range of visible light.

Reaction container and biochemical analysis method

A microfluidic device includes: a base plate allowing an electromagnetic wave to pass therethrough and having no autofluorescence; a microwell array formed on the base plate and including a wall layer in which a plurality of through-holes are formed in a thickness direction; and a lid member disposed opposite to the base plate in a state of being separated from the wall layer, wherein microwells are formed by the base plate and the through-holes formed in the wall layer, and wherein the wall layer is formed of a material containing a colored component that absorbs an electromagnetic wave of a predetermined wavelength.
