VEVOR Dual Frequency 22L Ultrasonic Cleaner with Heater for Jewelry Eyeglass

Jewelry Ultrasonic Cleaning Machine with Dual 28/40kHz Frequency for Versatile Cleaning 

Customers can fine-tune the cleaning power of the VEVOR jewelry ultrasonic cleaning machine by choosing between two frequencies: 28 kHz and 40 kHz. The lower frequency of 28kHz produces larger, more aggressive cavitation bubbles that are better suited to denser materials and heavier soiling. The higher 40kHz frequency produces smaller bubbles, which are best for delicate surfaces like gemstone settings, thin metal bands, and detailed engravings.

By switching between frequencies, the same machine can handle many applications in the same process. A worker can finish small pieces of jewelry at 40kHz after working on big metal parts at 28kHz in the same session. This versatility means that jewelers, dentists, and lab workers who handle a wide range of materials do not need to buy additional cleaning units. The machine is a cheap, space-saving purchase thanks to its versatility. 

3 Cleaning Modes Including Sweep, Turbo, and Degas for Targeted Stain Removal 

This jewelry ultrasonic cleaning machine has three cleaning modes: Sweep, Turbo, and Degas. Each mode is made for a different type of cleaning. In sweep mode, a 28 kHz frequency modulation spreads ultrasonic energy evenly across the tank. This prevents the tank from forming hot spots and ensures that every item, no matter where it is, receives the same treatment. The turbo mode enables a maximum output of 40kHz for short bursts of intense cleaning. This makes it effective against tough leftovers like wax, rust, and hardened oils.

Instead of relying on a single fixed result, these three modes work together to help operators clean more efficiently and more effectively. The ability to degas the solution before applying customized frequency and intensity settings is similar to the way expert labs and factories clean. This multimodal design can lead to shorter cycle times, better results, and reduced chemical use per batch for an ultrasonic jewelry cleaner capable of cleaning a wide range of materials and soil levels. 

500W Heating System with 0–80℃ Adjustable Temperature for Accelerated Cleaning Results 

The 500W heating element quickly raises the cleaning solution to operating temperature, reducing wait time and maintaining productive workflows. The LED panel shows a real time temperature measurement, fully adjustable from ambient to 80°C. Higher temperatures increase the activity of the cleaning solution's molecules, intensifying cavitation and accelerating the breakdown of mineral deposits, oils, and biological residues. Thermal and acoustic energy work together throughout the cycle because ultrasonic cleaning and heating can function simultaneously.

Lower temperature settings enable operators to take advantage of ultrasonic action while preventing thermal stress for heat sensitive objects, such as some adhesive set gemstones or coated optical surfaces. Higher temperatures can be precisely adjusted for heavy industrial soils or sterilization related applications in lab or hospital settings. This machine can adapt to a wide range of professional cleaning methods without the need for separate equipment for varied temperature requirements, thanks to its wide adjustable range and simultaneous heating and ultrasonic operation.

Digital Timer with Auto Shut Off and Memory Function for Consistent, Hands Free Operation 

Cycle durations from 0 to 30 minutes are supported by the integrated digital timer, which automatically shuts off when the predetermined time has elapsed. This feature reduces the possibility of overprocessing sensitive items and the necessity for manual monitoring. The machine switches to standby mode at the end of a cycle, reducing energy use during idle periods. Operators performing repeated batches with the same parameters do not need to re-enter values at the start of each new cycle, as the memory function retains the most recent time and temperature settings.

In high throughput settings where reliable, repeatable results are crucial, this combination of automation features is very beneficial. The ability to set a preset protocol (duration, temperature, and mode) and have the machine perform it exactly each time is advantageous for quality controlled laboratories, dental offices, and jewelry workshops. The LED screen keeps operators informed at a glance, without requiring close attention during the cleaning process, by clearly displaying the current temperature and the remaining cycle time in real time.

21.5L Stainless Steel Tank Built for Corrosion Resistant, High Capacity Batch Processing 

The 21.5L stainless steel tank is ideal for professional settings with high daily throughput, as it offers ample internal capacity to process large volumes of goods in a single cycle. The stainless steel construction is resistant to corrosion caused by alkaline cleaners, cleaning solutions, and mild acids sometimes used in industrial or laboratory processes. Additionally, the tank is completely sealed to prevent water leaks and rust, ensuring structural integrity and hygienic operation for a long service life. 

Rings, bracelets, eyeglass frames, dental instruments, circuit boards, and industrial components are just a few of the many item types that the tank's large capacity can hold at once without the need for several consecutive batches. A water drain connector minimizes downtime between cleaning runs by making post-cycle emptying and solution changes easier. Even when switching between different cleaning solutions or item categories during the working day, the stainless steel interior maintains clean operating conditions because it does not retain residues or odors between cycles.

Jewelry Ultrasonic Cleaning Machine with Portable Handle and Anti-Slide Feet for Flexible Placement 

With a built-in portable handle that makes it easy to move between workstations, benches, or storage spaces, this jewelry ultrasonic cleaning machine is designed for easy handling. The machine, which weighs 11.2 kg and measures 530 x 330 x 275 mm, occupies a reasonable amount of space on typical work surfaces while still providing 21.5 L of useful tank capacity. 

Anti-slip rubber feet prevent movement caused by ultrasonic cleaning vibrations, keeping the device firmly in place during operation. During prolonged use, the integrated heat dissipation system controls internal component temperatures, preventing thermal stress on the electronics and transducers and enhancing long-term reliability. The tank can be quickly and carefully emptied without tilting or lifting the device, thanks to a water drain link at the base.
