The all new Cavitator Ultrasonic Cleaners come in five sizes, designed to fit your cleaning needs. These cleaners generate ultrasonic waves that create millions of tiny bubbles through the process of cavitation. The bubbles gently clean and polish any surface they come in contact with, penetrating every nook and cranny to dislodge trapped dirt and debris. Medical instruments, glassware, even jewelry are quickly restored to their original lustrous finish without expending any effort. The gentle cleaning action is ideal for delicate items, too.
