The 4L Stainless Steel Ultrasonic Cleaner provides powerful and efficient cleaning for jewellery, precision components, watch parts and workshop tools. Featuring 100W ultrasonic power, a 40kHz frequency, adjustable heating up to 80°C and a 30-minute timer, this machine is designed for thorough and consistent cleaning.

Using advanced ultrasonic cavitation technology, high-frequency sound waves create microscopic bubbles within the cleaning liquid. These bubbles rapidly form and collapse, generating an intense scrubbing action that helps loosen dirt, grease, polishing residues and other contaminants. Their microscopic size allows the cleaning action to reach intricate details, narrow gaps and hard-to-access areas that conventional cleaning methods may miss.

The machine features two easy-to-use rotary controls for adjusting temperature and cleaning time, along with two indicator lights. The adjustable heating function is particularly useful for cleaning processes requiring warmed solutions.

Supplied with a cleaning basket, this 4-litre ultrasonic cleaner is a practical solution for professional jewellers, goldsmiths, repair workshops and precision cleaning applications.
