Abstract
A microchip used for a method for centrifugally dispensing a liquid sample by giving a revolving motion and a rotating motion to a rotary disk on which the microchip is mounted, includes a solution-pouring portion at a center thereof onto which the liquid sample is poured and channel patterns extending outward, with the solution-pouring portion as a center, and forming therein flow paths for the liquid sample and detection chambers which constitute portions for examining the liquid sample and in which the liquid sample is centrifugally dispensed. A centrifugal dispensing method using the microchip includes giving a revolving motion and a rotating motion to the rotary disk on which the microchip is mounted, thereby centrifugally dispensing the liquid sample in the detection chambers. A centrifugal dispenser using the microchip includes a rotary disk on which the microchip is mounted, means for revolving the rotary disk about a shaft and means for rotating the rotary disk about another shaft of the rotary disk.
