15L Ultrasonic Cleaner Professional Lab Machine with Digital Heater Timer Basket 304 Stainless Steel 40KHz for Jewelry Eyeglass

15L Professional Ultrasonic Cleaning Machine with Digital Heater, Timer, and Basket — 304 Stainless Steel, 40KHz This 15L ultrasonic cleaning machine is designed for professionals and serious home users who need reliable, repeatable cleaning results across a wide range of items and materials. The 15-liter tank is constructed from corrosion-resistant 304 stainless steel, a material chosen for its durability and resistance to rust, chemical cleaners, and daily wear. At the core of this unit is a 40KHz ultrasonic frequency system powered by industrial-grade transducers. These transducers produce high-frequency vibrations that create microscopic cavitation bubbles throughout the cleaning solution. When these bubbles collapse against surfaces, they dislodge contaminants from complex geometries, crevices, and irregular shapes—areas that manual brushing cannot reach effectively. This makes the machine well-suited for cleaning jewelry, eyeglass frames, watch components, circuit boards, laboratory glassware, and precision metal parts. The digital control panel gives you direct control over two key variables: time and temperature. The timer can be set from 0 to 30 minutes, and the heater adjusts from room temperature up to 176°F (80°C). The heating function is particularly useful for removing oil, wax, and grease-based contaminants, as heat reduces adhesion and allows the ultrasonic action to work more efficiently. Both functions can run simultaneously. A reinforced cleaning basket is included to protect both your items and the tank interior during operation. The basket makes it easy to load, retrieve, and rinse multiple small items at once. Four anti-skid rubber feet keep the unit stable during operation. It is suitable for use in jewelry shops, optical stores, dental clinics, laboratories, workshops, and home settings where professional-grade cleaning is required.
