Abstract:
1. A liquid introducing and reaction measuring device which is a device having; one or two or more reaction vessels, and one or two or more liquid introducing sections to which said reaction vessel is connectable such that it is freely detachable, and said reaction vessel is a vessel that has: a storage chamber in which liquid is storable, that has an opening part; a reaction chamber that is formed thinner or narrower than said storage chamber, and wherein at least a portion of said reaction chamber is translucent or semi-translucent; and at least one flow passage that communicates between said storage chamber or the exterior and said reaction chamber, and liquid is introduced into said reaction chamber by means of a liquid introducing section, comprising, in regard to said reaction vessel, a flow passage which, as well as communicating between said storage chamber and said reaction chamber, communicates between said reaction chamber and the exterior, and said liquid introducing section has a nozzle and a suction and discharging section that performs suction and discharging of gas via said nozzle, and the opening part of said storage chamber is connectable to a lower end section of said nozzle or is connectable to the lower end section of the nozzle via a cap that is connectable to said nozzle lower end section, and said reaction chamber of said reaction vessel is a gap formed between an outer face of a core, which is stored in a pipette tip comprising a thick diameter section and a thin diameter section that is thinner than said thick diameter section, and an inner face of said pipette tip, and said storage chamber is a space within said thick diameter section formed above said reaction chamber, the thin diameter section of said pipette tip is a flow passage that communicates between the exterior and said reaction chamber, and an opening part of said thick diameter section is connectable by means of said nozzle, and as well as having an optical information measuring section that obtains optical information within said one or two or more reaction chambers, it causes a reaction with regard to the liquid introduced into the reaction chamber by the liquid introducing section, and measures the optical information thereof.
