System and method for automated nucleic acid amplification

A device for automatically executing a process of generating an emulsion containing nucleic acids, amplifying the nucleic acids in the emulsion, breaking the emulsion, and separating and purifying said amplified nucleic acids, said device comprising:

• an emulsion generation unit for sealing beads to which nucleic acids are bound in a water-in-oil type emulsion, wherein the emulsion generation unit comprises a container;
• a nucleic acid amplification unit provided with a reaction vessel for amplifying said nucleic acids and a heating and cooling part for heating and cooling the reaction vessel;
• an emulsion breaking unit for breaking the emulsion after nucleic acid amplification, wherein the emulsion breaking unit comprises a container and is connected to the reaction vessel by a channel;
• and
• a nucleic acid purification unit for recovering said amplified nucleic acids from said emulsion breaking unit, wherein the nucleic acid purification unit comprises multiple tubes,
• wherein a head drop is disposed between said nucleic acid amplification unit and said emulsion generation unit and/or between said emulsion breaking unit and said nucleic acid amplification unit via a plurality of liquid transfer channels for liquid transfer, and
• wherein.
• said nucleic acid amplification unit is disposed below said emulsion generation unit, and said emulsion breaking unit is disposed below said nucleic acid amplification unit.
