I filmed how microbubbles are generated.
I recorded a video on how microbubbles are generated in 99.5% anhydrous ethanol. I placed a glass filled with ethanol into an empty tank and generated the bubbles using a nozzle with a flow rate of 420 cc/min. The pressure was about 0.27 MPa. In the first half, the solution was a thick white turbidity, but it became thinner in the second half. It seems that there is a bit of a trick to controlling the generation of microbubbles. Since I was using an electromagnetic pump, I tried to reduce vibrations by using a silicone rubber tube, but it burst during the experiment. The video was recorded after changing to a urethane tube where the pressure was applied. For more details, please contact us or refer to the catalog.

basic information
【Summary】 - A glass filled with ethanol was placed in an empty tank, and generation was carried out using a 420cc/min nozzle. - The pressure was approximately 0.27MPa. - The first half was a thick milky appearance, but it became thinner in the second half. - It requires some skill to control the generation of microbubbles. - Since an electromagnetic pump was used, a silicone rubber tube was employed to mitigate vibrations, but it burst during the experiment. - The video was recorded by changing the section under pressure to a urethane tube.

Company information
Our main business is the design of specialized machine tools for processing automotive parts and similar items. We have been researching microbubbles since 2000. In 2006, we developed a loop flow microbubble generation nozzle. We applied for a patent, which was published in May 2008. Since spring 2008, we have been supplying a special type to a company that sells ozone microbubble shower devices. General sales began in 2009.
