A fluid handling system includes a fluid handling device including an opening for introducing a fluid or discharging the fluid; a tube including a flange, where one end of the tube is for connection to the opening, and the other end of the tube is for connection to an introduction device for supplying the fluid or to a discharge device for discharging the fluid; a support member including a first through hole into which the tube is inserted, and movably supporting the tube; and a first elastic member including a second through hole into which the tube is inserted, and holding a part of the tube while the first elastic member is in contact with the flange and the fluid handling device or the support member.

Fluid handling system

The present invention relates to a microchannel chip capable of preventing fluid leakage caused by a lamination defect. Bottomed first regions, second regions, and third regions are formed by joining a film to a lower surface of the chip main body of a microchannel chip. The third regions are in communication with the second regions and are formed on carbon inks. The third regions are formed wider than the carbon inks are. The third regions are filled with an electroconductive adhesive.

Fluid handling apparatus and fluid handling system

In a case of generating a main body of an analysis tool and a micro flow path chip as separate components, to obtain an accurate sample analysis result and to accurately adjust fluid temperature inside the micro flow path chip without damaging an analytical light receiving section of the micro flow path chip. In analysis tool body () that detachably holds micro flow path chip () in a fixed manner, notch section () is formed in mount surface () onto which micro flow path chip () is to be mounted. Notch section () is formed in a predetermined range including a part corresponding to optical path L of light emitted from a lens of optical unit () in a state where analysis tool () is arranged on heat block ().

Analysis tool and microanalysis system

A micro-channel chip can be coated uniformly with a thin inorganic oxide film and can prevent an ionic hydrophobic substance from adsorbing through a surface of an inorganic oxide film. In the micro-channel chip, surfaces of inner walls of through-holes in an upper plate member and a channel of a lower plate member are entirely coated with a SiOfilm. The SiOfilm is formed of two layers, namely a bottom layer that contains a high content of carbon atoms and is formed in a part that contacts a resin substrate, and a surface layer that contains nearly zero content of carbon atoms and t is formed in a part that is exposed on the surface of a channel.

Micro-channel chip and micro-analysis system

There is provided a microfluidic device capable of preventing the flow of a fluid from being interrupted by bubbles generated in a micro flow passage. In a microfluidic devicewherein a micro flow passagehaving a substantially constant height is formed for allowing a fluid to flow therein and wherein a narrow portion is formed in a portion of the micro flow passage by forming a columnar portionor the like in the micro flow passage, an extending recessed portionfor extending the micro flow passage upwards is formed upstream of the narrow portion, and a plurality of raised portions extending in substantially parallel to longitudinal directions of the micro flow passage are formed on a portion of the bottom face of the micro flow passage facing the extending recessed portion if necessary.
