CHEMICAL ANALYZER AND GENE DIAGNOSING APPARATUS

摘要

A chemical analyzer for analyzing specific chemical substances such as nucleic acid extracted from a specimen containing a plurality of chemical substances capable of eliminating fluid remaining therein by a valve for controlling the flow of the fluid and preventing reagent in a previous process from contaminating a next process, wherein a constant amount of the fluid is held and the fluid is fed by a centrifugal force without installing the valve controlling the flow of the fluid in a reagent flow passage, holes are opened by a drilling machine (13) in order in the covers of ventilation holes (272, 273, 274) communicating with a detection container (450) in an analysis disk (2) and waste containers (460) and (470), and the analysis disk (2) is rotated to achieve the supply and the holding of fixed amount of a specimen.
