Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).
In 2009, it launched Trophon, a unique, automated technology for the high-level disinfection of intracavity and surface ultrasound probes. In 2010 Nanosonics warned that it had become aware of a substandard component being used in the production of its Tryphon EPR ultrasound disinfectant device and had moved to rectify the problem.

For autoclaving, cleaning is critical. Extraneous biological matter or grime may shield organisms from steam penetration. Proper cleaning can be achieved through physical scrubbing, sonication, ultrasound, or pulsed air. [17] Pressure cooking and canning is analogous to autoclaving, and when performed correctly renders food sterile.
Various UV-emitting devices can be used for SARS-CoV-2 disinfection, and these devices may help in reducing the spread of infection. [102] SARS-CoV-2 can be inactivated by a wide range of UVC wavelengths, and the wavelength of 222 nm provides the most effective disinfection performance. [102] Disinfection is a function of UV intensity and time.
Ultrasound (ultrasonic) is sound at a frequency high enough that humans can not hear it. Sound has a frequency (low to high) and an intensity (quiet to loud). Ultrasound is used to clean jewellery, weld rubber, treat abscesses, and sonography. These applications rely on the interaction of sound with the media through which the sound travels.
