PURPOSE:To enable minute separate pouring of reagent for rinsing with good operationability, by separate pouring the reagent through the use of sample cylinder, after absorbing the reagent in it, at the rinsing of sample probe and so on by reagent cylinder. CONSTITUTION:A selector cock 3 is mounted to the reagent cylinder 2 having a plunger 1, and the sample cylinder 6 having a plunger 5 is connected to the cock 3 via a tube 4. Further, the reagent tube 9 inserted in the reagent 7 in the reagent bin 8 is connected to the cock 3. The tip of the sample probe 11 which is connected to the said sample cylinder 6 via a tube 10 is made free in the sample case 13 having a sample 12. At the rinsing in the sample probe 11, the reagent for rinsing (distilled water) is suctioned in the cylinder 2 for a given amount, and after the sample is separately poured, the sampling arm 15 is turned to move the sample probe 11 on the rinsing tank 17, the rinsing reagent is moved in the sample cylinder 6 by selecting the cock 3 to the tube 4 and it is delivered to the tube 10 and the sample probe 11, allowing to rinse the tube inner wall through fine separate pouring. |
