How Ultrasonics Works
Ultrasonic sound is sound transmitted at frequencies generally beyond the range of human
hearing. In your ultrasonic bath, ultrasonic sound (sonics) can be used for cleaning
materials and parts, and for dissolving, homogenizing and degassing liquids. This is how it
works:
• As the sound waves from the transducer radiate through the solution in the tank, they cause
alternating high and low pressures in the solution
• During the low pressure stage, millions of microscopic bubbles form and grow. This process is
called CAVITATION, meaning “formation of cavities”
• During the high pressure stage, the bubbles collapse, or “implode” releasing enormous amounts
of energy
• For ultrasonic cleaning applications, these implosions act like an army of tiny scrub brushes. They
work in all directions, attacking every surface and invading all recesses and openings
• This same energy can be used for other applications, such as liquid dissolving, homogenizations,
and degassing
