Ultrasonic crusher, also known as ultrasonic cell crusher, is a multi-functional and multi-purpose instrument which uses ultrasonic to produce cavitation effect in liquid. The crushing machine is used to crush a variety of animals and plants, cells, bacteria and tissues. It can also be used for emulsification, separation, homogenization, extraction, defoaming, clearing, vegetation of nano materials, dispersion and acceleration of chemical reactions.
The working principle of ultrasonic crusher is based on the cavitation effect of ultrasonic wave in the liquid. The transducer generates high-strength shear force in the liquid at the top of tool head through the amplitude transformer to form high-frequency alternating water pressure, which makes the cavity expand and explode and break the cells. On the other hand, because the ultrasonic wave propagates in the liquid, the particles will produce a great acceleration, which will collide with each other or collide with the wall of the vessel and break up.
The crusher makes use of the dispersion effect of ultrasonic wave in the liquid to make the liquid produce cavitation effect, so that the solid particles or cell tissue in the liquid are broken. At present, most of the pulverizers can act on the solid materials, but the solid materials must be suspended in the liquid in order to achieve effective crushing. Because the molecules in the solid can't circulate, it can't produce the range effect, and the attenuation in the air is too serious.
Crusher is a kind of elastic mechanical wave in the material medium. It is a form of wave and a form of energy. When a certain dose of ultrasound propagates in the organism, the function and structure of organism can be changed through the interaction between them, that is, the ultrasonic biological effect.
Ultrasonic crusher is used to crush animal and plant cells, bacteria, dental spores or tissues. Disperse rare earth and all kinds of inorganic mineral powder. It is an ideal device for accelerating the reaction speed of chemistry, biology and physics and accelerating liquid degassing. In a word, ultrasonic pulverizer can realize the functions of extraction, comminution, emulsification, homogenization, suspension, variation, aerosol, accelerated dissolution, crystallization and preparation of biological samples under electron microscope.
