- colorimetry is usually performed by utilizing the fact that the reaction solution is colored or emits fluorescence or emits chemiluminescence by dispensing the measurement reagent.
- step 207 the measured reaction tube T is discarded by the reaction tube disposal means provided in the reaction tube transfer means 22 (FIG. 27).
- the reaction tube T is first supplied to the outer periphery of the reaction tube holders 16e, and only the outer periphery of the reaction tube holder is left as it is.
- the reaction tube T was initially supplied to 16 g of the reaction tube holder in the inner row, and then The process can be carried out in the same manner as in Figs. 19 to 25 using only one reaction tube holder in the circumference. Further, if necessary, the reaction tube T is first supplied to the reaction tube holder in the inner row, and the dispensing of the reagent is performed in the reaction tube holder in the inner row as it is, and then the reaction is performed.
- the reaction tube T is skipped to the reaction tube holder in the outer row by the tube transfer means 22 and transferred, and the reaction between the sample, the particles, and the labeling reagent is performed in the reaction tube holder in the outer row. It is also possible.
- the reaction time can be set by freely using the inner and outer rows. In setting the reaction time, various types of skip transfer positions by the reaction tube transfer means are determined by the number of reaction tube holders 16 of the reaction tube turret 14 installed. The reaction time can be set freely. Industrial applicability
- the present invention when performing an immunoassay, it is possible to automatically carry out the supply and disposal of the reaction tube, washing for B / F separation, dispensing of the reagent, measurement, and the like.
