Ultrasonic bench cleaning is a process that uses ultrasound to agitate the fluid. The ultrasound can be used with just water but use of appropriate solvent for the object to be cleaned and the type of soiling present enhances effect, Cleaning normally lasts between 3 to 20 minutes depends on the object has to be cleaned.
These cleaners are used to clean many different objects including scientific samples, lenses and other optical parts, surgical instruments, machined parts, fuel injectors etc.,
Ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure waves to agitate a liquid.The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics.This action also penetrates blind holes, cracks, and recesses.
Ultrasonic energy introduced into a solution causes alternating patterns of low- and high-pressure phases. During the low-pressure phase, bubbles, or vacuum cavities form, in the subsequent high pressure phase these bubbles implode violently. This is called cavitation.
