The design of this ultrasonic tub allows for it to wash instruments used in dental, medical veterinary, and cosmetic industries. Through cavitation, it is involved with ultrasound. This allows the user to thoroughly clean places that would otherwise be hard to reach manually, without the risk of contaminated instruments or unsafe handling. The tub can handle the heating phase of detergent, and stops automatically when the ideal temperature is reached. The temperature can be preset. Ultrasonic phases are intermittently activated with the device, the process of which reduces the gas dissolved in liquid. Thus, the efficiency of subsequent washing is improved.
