Ultrasonic cleaning uses cavitation bubbles induced by high-frequency pressure (sound) waves to agitate the liquid. The agitation produces high forces on stains adhering to metals, plastics, glass, rubber, and ceramics. Features: 【Premium Quality】Ultrasonic cleaner is made of stainless steel, which is corrosion resistance and long lifespan. Use the ultrasonic vibration treatment method to improve cleaning efficiency. 【Efficient Ultrasonic Cleaner】The lab ultrasonic cleaner has 35W ultrasonic power and 40Hz frequency which can bring better cleaning effect without damage. 【Tank Capacity】The ultrasonic jewelry cleaner has a tank capacity of 0.8L and comes with a cleaning basket that reduces friction during cleaning. 【Easy to Operate】After connecting the power supply, simply set the cleaning time and temperature setting time, then press the switch button, the work indicator will light up and start cleaning. 【LED Digital Display】Time setting: 0-30 minutes.
