Automated liquid-phase immunoassay apparatus

A liquid-based immune reaction analysis device using a cuvette having a plurality of chambers, wherein the plurality of chambers includes chambers filled with a sample, a reagent and magnetic beads, and the plurality of chambers includes chambers seated with a dispensing tip of a tubular shape and a washing tip of a cup shape, the liquid-based immune reaction analysis device comprising:

• a cuvette module to which the cuvette is mounted;
• a sampling arm in which the dispensing tip seated on the cuvette is detachably fitted to one end of the sampling arm;
• a straw arm in which a hollow is formed inside, the washing tip seated on the cuvette being detachably fitted to one end of the straw arm, and a magnetic body in the form of a beam configured to move up and down through the hollow;
• and
• a remover module having a remover plate,
• wherein the remover module detaches the dispensing tip from the sampling arm and the washing tip from the straw arm by using the remover plate, and places the dispensing tip and the washing tip on the cuvette,
• wherein the magnetic body is configured to attach the magnetic beads to the washing tip when moved down in the hollow of the straw arm.
