ABSTRACT:
The present invention provides an apparatus for efficiently transporting or dispensing transport objects including not only particles but also liquid samples. A liquid in a first liquid transport pipe (3) is fed at a liquid feed velocity (V1), and a liquid droplet is formed toward an open end of a second liquid transport pipe (4) disposed with an air gap (11) in between. The particle is released into the liquid droplet, so that the particle is enclosed in the liquid droplet. Suction with a liquid feed velocity (V2) is applied to the inside of the second liquid transport pipe. Since the relationship between V1and V2is V1<V2, the liquid droplet, after reaching the open end (10) of the second liquid transport pipe, is sheared off by suction, thereby forming a liquid section in the second liquid transport pipe. Thus, the particle in the liquid section, held under surface tension on a gas-liquid phase boundary, can be transported into a particle array container with stability in conjunction with the liquid section.
