A biomaterial measuring instrument is disclosed. The biomaterial assay instrument includes: a rotating body including one or more cartridge holders having a cuvette in which reagents and analytes in a sample occur reaction; and a main body, the main body includes at least one pair of light emitting part and light receiving part, and the at least one pair of light emitting part and light receiving part are used to optically measure the analyte in the sample, wherein the rotating body further includes: a light emitting part Optical waveguide, light-emitting optical waveguide for guiding light from a light-emitting portion to a light-irradiating surface which is a surface of an absorption cell other than a sample inflow surface and a centrifugal force applying surface, wherein the sample flows into the sample inflow surface wherein, centrifugal force is applied to the centrifugal force application surface by the rotation of the rotating body so that particle components in the sample are separated from the sample and are adsorbed to the centrifugal force application surface and deposited on the centrifugal force application surface; and the light receiving optical waveguide for the light receiving optical waveguide For guiding the light passing through the light-receiving measurement surface, which is a surface other than the sample inflow surface and the centrifugal force application surface, to the light-receiving portion. |
