Abstract: Provided is a reaction treatment apparatus in which, in a case of mixing a plurality of solutions in a microchip used in a biochemical reaction system, an electric field generation area for changing solute concentration distribution in the solutions is provided in a solution upstream fluid path. Diffusion between the solutions is accelerated by bringing an area with a high solute concentration into contact with another solution. This may shorten a time required for mixing the solutions.

Abstract: When different liquids are charged in a plurality of nozzles, the liquids are drawn by suction or pushed out reliably from the nozzles, so that the liquids collected by suction or pushing out can be reused. For this purpose, a removing unit, which has a cap that operates to cover nozzle discharge ports and to come into tight contact with a head, is provided. Suction is performed from each nozzle separately. Different collection tubes and collection tanks are provided for the removing unit. A liquid having the same liquid composition is accumulated in one collection tank for the same liquid composition via the collection tube of a liquid channel for the same liquid composition.

Abstract: A biochemical processing apparatus includes a plurality of reaction areas of different types, a pipette for dispensing a liquid, a pipette chip removably attachable on the pipette, and pipette chip storage spaces each capable of holding the pipette chip. The pipette chip storage spaces are provided in the plurality of reaction areas.

Abstract: A nucleic acid sample testing apparatus includes a transport carrier, which can move along a transport guide in a horizontal direction perpendicular to a direction of movement of a pipette unit. On the transport carrier, a tray equipped with a DNA microarray as a reaction container and a reagent container are arranged without being connected with each other. In addition, within a range of movement of the transport carrier and also within a movable range of the pipette unit, a processing section for carrying out a hybridization reaction is arranged. Above the range of movement of the transport carrier, a transport unit is arranged while being connected with a transport guide. The transport unit can move in the same direction as the moving direction of the pipette unit along the transport guide. In addition, a detecting section is arranged on the movable range of the transport unit.

Abstract: There is provided a biochemical reaction apparatus which can prevent contamination in a container having a reagent injected thereinto due to the invading of liquid droplets, dusts or the like from the outside into the container. Further, there is provided a biochemical reaction apparatus in which the refrigeration part can be hermetically sealed by an easy structure and even after the container is transported to a reaction part, the refrigeration part can be also hermetically sealed by the easy structure. The biochemical reaction apparatus includes: a reaction part, a refrigeration part for refrigerating a liquid supplied to the reaction part, a case member for covering the reaction part and the refrigeration part, and a transporting part allowing direct access from the outside of the case member to the inside of the refrigeration part.

Abstract: An apparatus for applying a solution to be used for manufacturing DNA chips is provided in a holding member with a sensor for monitoring a substrate temperature, a temperature adjusting section for controlling the substrate temperature, and a control section for feeding back a control temperature, by using the monitored temperature, to the temperature adjusting section for controlling the substrate temperature, wherein the substrate temperature is controlled to such a level as will accelerate the reaction between the substrate and probes in the sample solution.

Abstract: According to an object of the present invention, when different liquids are charged in a plurality of nozzles, the liquids are drawn by suction or pushed out reliably from the nozzles, so that the liquids collected by suction or pushing out can be reused. For this purpose, a removing unit is provided which has a cap that operates to cover nozzle discharge ports and to come into tight contact with a head.

Abstract: An ink tank includes an ink containing portion for containing ink, a bottom surface provided with three projections for supporting the ink tank, an ink supply portion for leading ink out of the ink containing portion to the exterior a top surface opposing to said bottom surface, and a plurality of lateral surfaces adjacent to the bottom and top surfaces. The plurality of lateral surfaces include one set of opposing surfaces extended in a lengthwise direction of the ink tank. A grip portion is provided at one end of the ink tank in the lengthwise direction of insertion thereof. Two of the three projections are provided on the bottom surface in an opposed relation in areas near the opposing surfaces of the plurality of lateral surfaces, the ink supply portion being provided in an area of the top surface opposed to an area located on or within lines connecting the three projections.

Abstract: Disclosed is an ink tank coupling method for an ink jet recording apparatus comprising a recording head, an ink supply needle, and a moving unit for moving the ink supply needle to a predetermined position, the recording apparatus being able to detachably mount an ink tank containing ink supplied to the recording head. The method comprises a step of holding and fixing the ink tank to a predetermined position by releasing a movement preventing unit which prevents movement of the ink supply needle caused by the moving unit, and pressing the ink tank to abut a reference surface with an operation of attaching the ink tank to the recording apparatus, and a step of inserting the ink supply needle to the predetermined position in the ink tank by the moving unit after the holding and fixing step.
