PURPOSE:To enable a small size instrument to distribute plural kinds of reagents by rotatably arranging a plurality of reagent distributors each comprising a reagent bottle, a pump unit communicating with the reagent bottle via a calve and performing the suction and discharge of a reagent and a nozzle on the side of a discharge opening. CONSTITUTION:A reagent distributor 60 is constructed by integrating a reagent bottle 61 for containing a reagent, a T-shaped valve 62 arranged along the side wall of the reagent bottle 61 and having openings in three directions, a pump unit 63 communicating with the upper opening of the valve 62 for conducting the suction and discharge of the reagent and a nozzle portion 64 that is connected to the lower opening of the valve 62 at a top end and distributes the reagent from a bottom end. The side opening of the valve 62 communicates with the inside of the reagent bottle 61 through the side wall thereof. A passage for communicating the side and upper openings with each other is formed within the valve 62 during the suction of the reagent and a passage from the reagent bottle 61 to the inside of the valve 62 is closed and, at the same time, another passage for connecting the upper and lower openings to each other is formed during the discharge of the reagent. Thus, the size of the distributor 60 can be reduced and a plurality of the distributors can be rotatably arranged to distribute plural kinds of the reagents. |
