What is ultrasonic cleaning?

Ultrasonic is sound generated above human audible level. In real life, high pitch sound is created by high frequency and alternatively the low and base tone is created by low frequency. Frequencies above 16 kHz in general are being considered as ultrasonic. Typical ultrasonic frequencies used for cleaning purposes are from 20 kHz to 80 kHz.

How sound can clean?

In an ultrasonic cleaner, the object to be cleaned is placed in a chamber containing a suitable solution (in an aqueous or organic solution, depending on the application). In aqueous cleaners, the chemical added is a surfactant which breaks down the surface tension of the water base. An ultrasound generating transducer built into the chamber, or lowered into the fluid, produces ultrasonic waves in the fluid by changing size in concert with an electrical signal oscillating at ultrasonic frequency. This creates compression waves in the liquid of the tank which ‘tear’ the liquid apart, leaving behind many millions of microscopic ‘voids’ or ‘partial vacuum bubbles’ (cavitation). These bubbles collapse with enormous energy; temperatures and pressures on the order of 5,000 K and 20,000 lbs per square inch are achieved however, they are so small that they do no more than clean and remove surface dirt and contaminants and causes no damage. The higher the frequency, the smaller the nodes between the cavitation points, which allows for cleaning of more intricate detail even between cracks, Great for Jewellery. 

Ultrasonics – the eco friendly solution?

The main agent in Ultrasonic cleaning is tap water, With our range of cleaners no longer do you need to use harsh chemicals with even harsher effect to the environment. Most ultrasonics will give great results with just washing up liquid
