Patent abstract
In a chemical analysis apparatus for extracting a specific substance, such as nucleic acid, from a sample containing a plurality of chemical substances, solutions remaining in valves are prevented so that a reagent in an earlier step does not contaminate the subsequent steps. Predetermined quantities of solutions are carried and supplied by centrifugal force without providing valves for controlling the flow of the solutions. After perforating the lids of ventilation holes 272, 273, 274 communicated with a detection container 450 and disposal containers 460 and 470 in an analysis disc 2, the analysis disc 2 is rotated to supply and carry a predetermined quantity of the sample.
