Function of ultrasonic sonicator

What are the composition of ultrasonic sonicator?

Ultrasonic sonicators, sometimes called homogenizers or sonifiers, destroy tissue and cells through cavitation and ultrasound.

They consist of three parts:

A generator that provides and controls the power.

A transducer (also known as a converter) containing a piezoelectric crystal that converts electrical energy into mechanical motion at very high frequency.The converter also amplifies the signal.

The titanium probe or "horn" vibrates rapidly along the longitudinal direction to transmit ultrasonic energy to the sample.

Homogenization occurs both directly through ultrasonic forces and through cavitation (the rapid formation and rupture of bubbles).

The combination of these forces makes ultrasonic homogenizers ideal for cell rupture and particle size reduction.

What are the working principles of ultrasonic sonicator?

Ultrasonic sonicator is the use of ultrasonic cavitation in liquids and other physical effects to achieve homogenization, emulsifying, dispersing, mixing and extraction. Physical action refers to the formation of an effective agitation and flow disrupting medium in the liquid, the pulverizing of the particles in the liquid, mainly the collision between the liquid, the micro phase flow and the shock wave leading to changes in the surface morphology of the particles.

Cavitation refers to the generation of holes (small bubbles) in the weaker part of the liquid under the action of ultrasonic waves. The small bubbles pulsate with the ultrasonic waves, and the holes collapse in one sound cycle.

Where are the ultrasonic sonicator applications?

Ultrasonic treatment of chemical extraction, biodiesel production, organic synthesis, treatment of microorganisms, degradation of toxic organic pollutants, chemical reaction rate and yield, catalytic efficiency of catalysts, biodegradation treatment, ultrasonic anti-scaling, biological cell comminution, dispersion and coagulation A local small environment that is very beneficial to the reaction process can greatly increase the reaction rate and reduce the reaction conditions.

What are the advantages of ultrasonic sonicator?

1. Ultrasonic sonicator produce small particle/droplet and narrow distribution curves.

2. Ultrasonic sonicator can handle high concentrations of solids.

3. Ultrasonic sonicator can prepare stable suspensions, dispersions and emulsions.

4. Ultrasonic sonicator can be precisely controlled because important parameters (e.g., amplitude, power) can be affected and adjusted.

5. Ultrasonic sonicator is very effective, energy saving, easy to operate and safe.
