ultrasonic homogenizer (sonicator)
Ultrasonic homogenizers, the modern version of “mortar and pestle”, they can disrupt tissues and cells through cavitation and ultrasonic waves. Ultrasonic Homogenizers can disintegrate most cells, bacteria, spores or tissue. They can prepare an emulsion down to 1/100 of a micron homogenize “immiscible” liquids, accelerate enzymatic and chemical reactions, stimulate bacterial activity, disperse solids in liquids and degas liquids.
Ultrasonic Homogenizers are recommended for homogenization and lysis of laboratory samples that do not require traditional grinding or rotor-stator cutting techniques for processing. Small and large ultrasonic probes are used in a variety of sample volumes to be processed. A solid probe allows for less chance of sample loss and cross-contamination between samples.
Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes. Ultrasonic frequencies (around 20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication. In the laboratory, it is usually applied using an ultrasonic bath or an ultrasonic probe, colloquially known as a sonifier.
Sonication can be used for the production of nanoparticles, such as nanoemulsions, nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of plant oil, extraction of anthocyanins and antioxidants, production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive thinning, and many other processes. Sonication is also commonly used in nanotechnology for evenly dispersing nanoparticles in liquids.

Specific Parameters of Cell sonicator
Working principles of Ultrasonic Homogenizers (Cell sonicator)
Ultrasonic homogenization is achieved using sound waves and ultrasonic waves that alternately compress and inflate when encountering objects. When the material is under the action of ultrasonic waves, the material and liquid Ultrasonic Extraction Machine will be expanded by the bubble when it is in the expansion half cycle; when it is in the compression half cycle, the bubble will shrink when the pressure changes
Ultrasonic homogenization is based on the principle of using sound waves and ultrasonic waves to rapidly alternately compress and expand when encountering objects. When the material is under the action of ultrasonic waves, when the material is in the expansion half cycle, the material liquid is expanded by the air bubble; when it is in the compression half cycle, the air bubble shrinks when the pressure changes greatly and the pressure is lower than the low pressure. At that time, the compressed air bubbles collapse sharply, and a “hole” phenomenon occurs in the feed liquid. This phenomenon disappears with the pressure change and the unbalance of the external pressure. At the moment when the “hole” disappears, the liquid The surroundings cause very large pressure and temperature increase, and play a very complicated and powerful mechanical stirring effect to achieve the purpose of homogenization. At the same time, at the interface where the “cavity” has a density difference, the ultrasonic wave also reflects and produces intense stirring. According to this principle, the ultrasonic homogenizer is a device that puts an ultrasonic generator at a frequency of 20 to 25 kHz into the feed liquid or uses a device that allows the feed liquid to have a high-speed flow characteristic, and uses ultrasonic stirring in the feed liquid to make the feed liquid achieve Homogeneous.
