Ultrasonic cleaning theory
By using an electrical generator which generate a high-frequency signal, the tubular transducer set in liquid will induce compression and rarefaction waves.The liquid which affected by two kinds of waves constantly creates pushing and expanding
that forms and explode tiny bubbles in the liquid(cavitation).
These tiny bubbles can attach on the surface of whatever object place in the liquid and when bubble explode, any contamination can be removed.
