Abstract: The object of the present invention is to enable a probe to uniformly encounter biopolymers in a sample solution, regardless of a position in a reaction chamber. In the present invention, a fluid displacement between a reaction chamber and ports communicating therewith in a biochemical reaction part is controlled by switching control means formed of valves and syringe pumps. After a hybridization solution is poured into the reaction chamber, air is introduced through ports by valves, and is sucked from other ports by syringe pumps. The valves are suitably turned on and off to switch the flow of the hybridization solution in the reaction chamber to directions Y, A and B, thus executing agitation in various directions. Thus, each probe is made to more securely encounter the biopolymers present in the hybridization solution, thereby achieving a hybridized coupling more efficiently regardless of the position of the probe.
