Container assembly and container assembly kit

A container assembly kit comprising:

• a washing container that seal-tightly holds a washing liquid and a fluid that is immiscible with the washing liquid;
• and
• an elution container that seal-tightly holds an eluent and a fluid that is immiscible with the eluent,
• the washing liquid being a liquid with which a substance-binding solid-phase carrier on which the biological substance is adsorbed is washed,
• the eluent being a liquid with which the biological substance is eluted from the substance-binding solid-phase carrier, and
• the washing container and the elution container being able to be joined to form a flow channel through which the biological substance is moved.

A container assembly kit comprising:

• an adsorption container that seal-tightly holds an adsorbent and a fluid that is immiscible with the adsorbent;
• and
• a washing container that seal-tightly holds a washing liquid and a fluid that is immiscible with the washing liquid,
• the adsorbent being a liquid in which a nucleic acid is adsorbed on a substance-binding solid-phase carrier,
• the washing liquid being a liquid with which the substance-binding solid-phase carrier on which a biological substance is adsorbed is washed, and
• the adsorption container and the washing container being able to be joined to form a flow channel through which the biological substance is moved.

A container assembly kit comprising:

• a first washing container that seal-tightly holds a first washing liquid and a fluid that is immiscible with the first washing liquid;
• and
• a second washing container that seal-tightly holds a second washing liquid and a fluid that is immiscible with the second washing liquid, the second washing liquid differing from the first washing liquid,
• the first washing liquid and the second washing liquid being a liquid with which a substance-binding solid-phase carrier on which a biological substance is adsorbed is washed, and
• the first washing container and the second washing container being able to be joined to form a flow channel through which the biological substance is moved.
