Ultrasonic baths or cleaners are one of the most versatile equipment used across the spectrum of industries for cleaning or mixing purposes. They come in the shape of baths or probe type, depending on usage needs.
Ultrasonic waves are the term used to describe waves that have a frequency above the audible range of humans. When high intensity ultrasound is applied to a liquid, the observed result is the creation of millions of tiny bubbles (or cavities) in the liquid. These so called cavities are produced by the alternating high and low pressure waves created by high frequency (ultrasonic) sound. During the low pressure phase, these bubbles grow from microscopic size until, during the high pressure phase, they are compressed and implode. This process is known as cavitation. When this occurs at the interface of the parts to be cleaned, the surface of the parts given the relative lack of compressibility of the cleaning fluid experiences a local impact, thus, cleaning the instruments in the process.
Ultrasonic cleaners come in the form of baths, which range from 4 litres to 500 litres or in the form of a probe type sonicator, which are used to disperse solids or liquids in a medium. The probe type sonicators typically come with capacity of 100ml for dispersion. Both these types of sonicators are custom built to suit user requirements.
