Micro bubble generator

This device has been developed mainly for laboratories to support research and development related to microbubbles. It is provided along with the measurement results of the bubble size distribution generated in the experimental tank.

Micro bubble generation principle

This device uses a self-priming, air bubble generation mechanism. In this method, the gas taken in from the suction port is crushed and refined by the shear force of the pump impeller. It has been studied to have a high physiologically active function as compared to the pressurized method.

Feature

・Allows experiments under conditions where the generated bubble distribution is known
・Uniform bubble size distribution
・Self-priming system eliminates the need for a compressor
・All gases can be safely used as needed
・Experiment with small amount of sample possible Small size and space saving

Micro bubble occurrence situation
(in seawater)
