With the rapid development of China's economy and the increase of scientific research laboratories, there is a common problem for all scientific researchers? How to clean quickly and efficiently has become a common concern? Because each experiment requires numerous experimental demonstrations, resulting in numerous stains left on the inner wall of the beaker caused by the high-frequency use of glass beakers, reagent tubes and other glassware. At this time, many people are needed to clean. At the beginning of China's scientific research institutions, most of the work of cleaning utensils was done manually. In the 1990s, China began to gradually introduce foreign advanced technology, commonly known as ultrasonic cleaning, which is to use water as the medium, and high-frequency vibration makes the water molecules explode, like a pulse jet to quickly peel off the stains on the surface of objects, The material of the object itself will not be affected, so this process is called "cavitation effect". It is also one of the green cleaning schemes recognized as environmental protection in the world.
