Draper Ultrasonic Cleaning Tank, 27L uses the power of ultrasonics to clean your items. This means that the tank generates high-frequency sound waves that create microscopic bubbles in the cleaning fluid. These bubbles then implode, creating a cavitation effect that gently removes dirt and grime from the surface of your items. The tank has a capacity of 27 liters, so it's large enough to clean even bulky items. It also has a built-in heater that can be set to a temperature of up to 80 degrees Celsius, which helps to improve the cleaning performance.
