A container assembly prevents a situation in which an aqueous liquid layer is contaminated by a component of another aqueous liquid layer even when stored for a long time. A container assembly (1) has a structure in which an adsorption container (100), a reaction container (400), a washing container (200), and an elution container (300) are joined to form a flow channel (2) through which the target nucleic acid is moved. The washing container (200) may include a first washing container (210), a second washing container (220), and a third washing container (230). The washing container (200) seal-tightly holds a first washing liquid (12), a second washing liquid (14), a third washing liquid (16), a first oil (20), a second oil (22), a third oil (24), and a fourth oil (26), the first oil (20), the second oil (22), the third oil (24), and the fourth oil (26) being immiscible with the first washing liquid (12), the second washing liquid (14), and the third washing liquid (16). The first washing liquid (12), the second washing liquid (14), and the third washing liquid (16) are liquids with which a magnetic bead (30) on which a nucleic acid is adsorbed is washed. The elution container (300) seal-tightly holds an eluent (32) and a fluid (26) that is immiscible with the eluent (32). The eluent (32) is a liquid with which the target nucleic acid is eluted from the magnetic bead (30). |
