ABSTRACT:
A tube is inserted into a first liquid layer, and an air bubble is generated at a tip opening of the tube. The tube is then moved toward a second liquid layer while retaining the air bubble, and a change in the internal pressure of the tube caused by the air bubble reaching the boundary between the first and second liquid layers is detected. After the tip opening of the tube is raised to the top surface of the first liquid layer, the first liquid is sucked up by the tube while the tube is moved to the position where the pressure change was detected.
