Ultrasonic Machine 3.2L 120W 40kHz Cleaner - Heater & Degas

In this review the Ultrasonic Machine 3.2L 120W 40kHz cleaner is evaluated as a compact lab and bench-top cleaning tool ideal for hobbyists, jewelers, dental techs and electronics technicians who need a reliable way to remove grime from small parts. The single biggest reason to buy is its combination of a powerful 40kHz ultrasonic cleaning action with an integrated heater and degas mode, which together improve soil removal on delicate items without harsh scrubbing.

Key Features

• 40kHz Ultrasonic: High-frequency sound waves provide a gentle but effective cleaning action that reaches crevices on jewelry, eyeglasses and small parts.
• 120W Cleaning Power: Robust ultrasonic output delivers enough energy to dislodge dirt, oils and contaminants from delicate surfaces without mechanical abrasion.
• 150W Heating Element: Adjustable heater accelerates cleaning by raising solution temperature to break down stains and reduce rust-prone residues.
• Degas Mode: A dedicated degassing function removes dissolved gas from the cleaning liquid to improve cavitation and overall cleaning efficiency.
• Digital Timer and LED Display: Precise time control from 0 to 30 minutes gives repeatable cycles for consistent results across batches.
• 304 Stainless Tank: A 3.2L corrosion-resistant tank sized for small assemblies and dental or optical parts for long-term durability.

Who It's For

This cleaner suits small labs, dental clinics, watchmakers, jewelers and electronics hobbyists who regularly clean delicate parts and need consistent, hands-off cleaning. The moderate 3.2L capacity handles multiple small items-rings, glasses, circuit boards or denture parts-without occupying a large bench space.

It is less appropriate for very large items or high-throughput industrial lines; those users should look at larger-capacity or industrial ultrasonic systems. Also, users who are extremely noise-sensitive should note that some customers report noticeable operating sound during cycles.

Pros & Cons

Pros

• Effective cleaning action for delicate parts thanks to 40kHz frequency and 120W power.
• Built-in heater and digital timer allow controlled, repeatable cleaning cycles and better stain removal.
• Degas mode improves performance and helps protect samples and the device over time.
• Sturdy 304 stainless tank and compact 3.2L capacity balance durability with convenient size.

Cons

• Some users note mixed feedback on noise level, with a few finding the unit louder than expected.
• Heat generation during use can be noticeable; work area ventilation and care with temperature-sensitive items are advised.

Frequently Asked Questions

Is this unit safe for jewelry and eyeglasses?
Yes. The 40kHz frequency is suitable for most jewelry and eyeglasses, but remove very soft stones or glued components before cleaning.

Can it heat the cleaning solution?
Yes. The unit has a 150W heating element with digital control to raise solution temperature for better cleaning.

What does degas mode do?
Degas mode removes dissolved gas from the liquid to improve cavitation and increase cleaning efficiency, especially on new solution fills.
