PURPOSE:To enable the speeding up of processing and microscopic application of a sample and a reagent with a natural agitation by repeatedly rotating a rotor having a number of reaction tubes radially in an angle range of approx. 180 deg. about the horizontal axis. CONSTITUTION:As a rotor 1 having a number of reaction tubes (a)... fixed thereon is not fixed on a shaft 13, the rotation thereof is transmitted thereto by a pressing force between valve blocks 4 and 7. At the position A, a sample and a first reagent are introduced into the reaction tubes (a) through a pipe 9 and driven by a motor 20, the rotor 1 rotates to move the reaction tube (a) to the position of rotating it by about 180 deg.. Then, a lock pin 22 is forced into a hole 21 of the rotor 1 to fasten the rotor 1 alone and the valve blocks 4 and 7 are reversed by 1 step. After the lock is released, the rotor is reversed as a whole to place a reaction tube (b) at the position A and the sample and the first reagent are introduced. The operation is repeated to shift the reaction tube (a) to the position B, a second reagent is mixed and then, the reaction tube is shifted to the position C to perform a colorimetric detection. At the proper position D, the mixture of the sample and the reagent is drained through pipes 2a... and a pipe 6 and a washing is performed at the position E. |
