The Mettler CAVITATOR ME 6L Heated Ultrasonic Cleaner generates ultrasonic waves that create millions of tiny bubbles that gently clean and polish any surface to clear dirt and debris. The bubbles gently clean and polish any surface they come in contact with, penetrating every nook and cranny. Medical instruments, glassware, jewelry and other delicate items are quickly restored to their original lustrous finish without any effort. Additionally, these Ultrasonic Cleaners come in five sizes, designed to fit your cleaning needs.
