Ultrasonic cleaners create microscopic bubbles which penetrate small crevices and explode upon contact, removing debris that regular washing can leave behind. Ultrasonic cleaners prevent particles from contaminating cloths or scratching samples during the polishing process.

Ultrasonic cleaning is also useful prior to mounting, as it improves adhesion of the mounting material to the sample.

All units have a stainless steel tank, mechanical timer, and cover. Units with digital timers and/or heaters are also available.
