Everything that makes a sound vibrates, and everything that vibrates makes a sound. However, not all sounds are audible. Ultrasound literally means beyond sound; sound above the human audible spectrum. Using 18,000 Hertz (cycles per second) as the approximate limit of human hearing, Ultrasonics refers to sound above that frequency.
Labotal has two different top of the line of Ultrasonics equipment - Ultrasonic Processors for different biological applications from SONICS & MATERIALS; and Ultrasonic Baths for throughly cleaning from ELMA.
