Provided is a fine bubble supply device and a fine bubble analyzing system capable of more stably supplying fine bubbles unstable in a liquid. A fine bubble generating device generates fine bubbles. A retention vessel stores a liquid therein, and an inlet pipe and an outlet pipe of the fine bubbles are connected to the retention vessel. The fine bubbles generated from the fine bubble generating device are introduced into the liquid in the retention vessel through the inlet pipe to be retained in the liquid. The fine bubbles retained in the liquid are led out to a supply destination (fine bubble characteristic evaluation device) through the outlet pipe.

Fine bubble supply device, and fine bubble analyzing system

By irradiating target liquid L containing fine bubbles with ultrasonic waves from an ultrasonic irradiation device, the fine bubbles in the target liquid L is reduced. By irradiating the target liquid L with ultrasonic waves, fine bubbles in the target liquid L can be reduced effectively. By using ultrasonic waves, bubbles with small diameters, particularly fine bubbles, can be effectively reduced, so that fine bubbles in the target liquid L can be efficiently reduced.
