In this mechanism, the magnetic beads in the reaction vessel are circulated and moved by magnetic force, and the reaction solution in the reaction vessel is stirred and mixed. Furthermore, Patent Document 1 describes, as an example, “a reaction vessel is about 2 O mm ⁇ 6 O mm, its thickness is about 0.2 mm, and its capacity is about 2500 L”. .
