PURPOSE: To measure blood component without moving a specimen by placing a capillary where the specimen is sealed at the upper side of a slit which is provided on the upper surface of a rotar, performing centrifugation by rotating the rotar, allowing light which is transmitted through the specimen to be transmitted, performing photoelectric conversion of the amount of received light, and then measuring the hematocrit value of blood.
CONSTITUTION: A hole 4 for engaging a rotary shaft 3 of a drive body for rotating a disc-shaped rotar 1 is provided. A slit 12 is provided through the rotar 1 toward the outer periphery from the center of the rotar 1. A capillary 11 where whole blood which becomes a specimen is sealed is placed at the upper side of the slit 12 and centrifugation is performed by rotating the rotar 1. While the capillary 11 after separation is placed on the slit 12, light is projected from a light source 13 from the upper surface side of the rotar 1 and is transmitted to the lower side of the rotar 1 via the slit 12. The transmission light is converted to current by a light receiver 14, current is converted to voltage by a preamplifier 15, and a matrix value is calculated by an operation circuit 17 through a logarithmic amplifier 16 and then is displayed on a display 18.
