"What is the difference between fine bubbles and microbubbles?" We explain the differences! We also summarize the characteristics of microbubbles. *Materials available upon request.
"Fine bubbles" is a general term for microbubbles and ultrafine bubbles (nano-sized bubbles), referring to bubbles with a diameter of less than 0.1 mm. Microbubbles appear more like "white turbidity" than "bubbles" to the naked eye, and their concentration is determined by the amount of gas dissolved in the water. Ultrafine bubbles are not visible to the naked eye, but can be confirmed by shining a laser beam on them. They drift in the water without rising to the surface. 【Characteristics of Microbubbles】 - The peak diameter of microbubbles is several tens of micrometers (varies depending on the generation method and conditions) - Visible to the naked eye (difficult to see below 5 micrometers) - Negatively charged - Lifespan in fresh water is several minutes to several tens of minutes - Enhances gas dissolution - Rise and mostly burst at the water surface, escaping into the atmosphere *For more details, please refer to the related links or feel free to contact us.

basic information
【Characteristics of Ultra Fine Bubbles (Nano-sized Bubbles)】 ■ The peak bubble diameter is around 110nm ■ Not visible to the naked eye (currently measurable with instruments) ■ Bubbles are negatively charged ■ The lifespan of bubbles in pure water is several days, floating in the water movement without rising ■ If stored properly, they can exist for several months to a year ■ Increasing the purity of ultra-pure water makes it impossible to measure UFB *For more details, please refer to the related links or feel free to contact us.

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.
