Ultrasonic unit definition
Ultrasonic unit means a unit approved by the department, physically large enough to fully submerge instruments in liquid, which removes all foreign matter from the instruments by means of high-frequency oscillations transmitted through the contained liquid.
Ultrasonic unit means a device that removes debris by a process called cavitation, in which waves of acoustic energy are propagated in aqueous solutions to disrupt the bonds that hold particulate matter to surfaces.
