        Ultrasonic homogenizers are multi-function and multi-purpose instruments that utilize intense high frequency sound to induce cavitation in liquid. As the cavitation bubbles collapse, high shearing energies disrupt animal and plant tissue, and lyse yeast, bacteria and spores.  The ultrasonicator can also be used for non-biological applications such as emulsification, nanoparticle dispersion, intense washing or acceleration of chemical reactions (sonochemistry).

    The principle of working

        This machine is made up of an ultrasonic power supply and an ultrasonic transducer assembly (generator or probe). The ultrasonic power supply converts the input single-phase electricity of 110VAC, 60Hz into an alternating electrical signal of 20-25 kHz, 600V.  The circuitry consists of a power rectifier, power switcher, a frequency conversion system, power amplifier, phase-locked frequency automatic tracking device, power regulator, power detector, power protector device and microcomputer controller.
        Driven by the appropriate impedance and power, the transducer subassembly generates mechanical energy through a piezoelectric resonator which is focused and amplified with a tuned, titanium metal horn (probe). When the probe tip is immersed in sample solution, intense, high frequency sound waves coming from the tip of the probe induce cavitation.  As the cavitation “bubbles” collapse, high shear forces break or tear open the cells.  Indeed, cavitation forces are high enough to break covalent bonds and, hence, ultrasonicators can be used to fragment high  molecular weight DNA.
