Liquid - liquid system dispersion (emulsion): with ultrasonic dispersion machine, it does not use emulsifier. In many cases, phacoemulsification can be obtained below 1μm particles. The formation of this high quality emulsion is mainly due to the effect of ultrasonic strong cavitation near the dispersing tool. Ultrasonic liquid dispersion machine is widely used in many fields, such as food, cosmetics, medicine, chemistry and so on. http://www.fycgsonic.com/ultras...-dispersion-machine.html
