PURPOSE:To make an automatic analysis more accurately and perfectly as a new method of analyzing apparatus for injecting a fixed quantity of a reagent, by rotating a turntable at high speed, breaking a thin film by centrifugal force acting on the reagent and injecting the reagent into a reaction vessel. CONSTITUTION:A reagent capsule A is provided with a tapered cylindrical surrounding wall 35 and thin films 36, 37 are stretched at its both end parts and a reagent 38 is enclosed in the inside of the capsule A. Intensity of the film 37 provided at the lower end side of the capsule A is regulated to such a degree that the film 37 is broken by the centrifugal force of the reagent 38 generated by rotating a turntable 1 at high speed and the intensity of the film 36 provided at the upper end side is regulated to such the degree that the film 36 is broken through by lowering a reaction liquid suction nozzle 25. In this manner, the capsule A is dropped from a chute 18 and is set in a processing vessel 9 and the turntable 1 is rotated at high speed under this condition. At this time, the film 37 is broken by the centrifugal force generated in the reagent 38 to inject the reagent 38 into the vessel 9. Next, the vessel 9 after injecting the reagent is successively subjected to a mixer 26. |
