Commercial Grade 6 Liters Heated Ultrasonic Cleaner for Eyeglasses Rings Cleaning with Heater and Digital Timer Introduction Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signals in fluid. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the type of soiling present enhances the effect. Microscopic bubbles that expand and rapidly collapse cause cavitation, which creates an effective cleaning action on the surface of object being cleaned. Special for cleaning jewellery, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, etc. Features: Durable stainless steel construction. Ultrasonic cleaning and heating can work at the same time. Drains with Flow Control Valve for easy cleaning and rinsing Stainless steel tight fitting lid with handle to prevent water heat from diffusing. High efficiency saves cleaning solvent, thermal energy, work place and labor! Built-in powerful transducer can strengthen the ultrasonic power and make superior cleaning outcome. Use only tap water for general cleaning, you also can add about 5-10 ML of detergent into water to enhance wash result when needed.
