PURPOSE: To improve a photometric system while the beneficial point of a conventional method in measuring sample forming work is put to practical use, by using a separable microplate at every one row and making it possible to perform photometry without interposing a liquid surface.
CONSTITUTION: Each microplate 26 comprises a unit plate at every one row and is provided with several wells 22. The microplate 26 is subjected to the portionwise injection of a specimen or a reagent and incubation in a state incorporated in a holding frame 23 and subsequently applied to an apparatus to perform measurement. The microplate 26 to be measured is mounted on a specimen stand 27 and a unit plates 21 are successively fixed to a photometric holder 42 to be scanned as shown by a broken line and each well 22 is moved on the optical axis of a spectrometer 54 to successively measure the sample liquid allowed to fill each well 22. Measuring light is incident to the sample liquid from the lateral side of the well and, at the time of the measurement of absorbancy, lights emitted from the opposed side surfaces of the well are measured and, at the time of the measurement of fluorescence, the light emitted from the bottom surface thereof is measured.
