UNIZ UC-4120 Ultrasonic Cleaner 3.2L Stainless Steel Tank Professional Cleaning

The UNIZ UC-4120 is a digital ultrasonic cleaner primarily used for professional and household cleaning tasks, such as removing resin residue from 3D printed photopolymer models, as well as jewelry, eyeglasses, dental instruments, lab tools, and other small items. It operates by generating high-frequency ultrasonic waves (40 kHz) that create cavitation bubbles in a cleaning liquid (e.g., water, alcohol, or specialized solutions), which implode to dislodge dirt, debris, and contaminants without manual scrubbing or harsh chemicals. The device is eco-friendly, certified with CE, FCC, ROHS, and PSE standards, and emphasizes safety, reliability, and efficiency. It's often associated with the UNIZ brand in certain markets, particularly for 3D printing post-processing, though it appears to be manufactured by LANGEE or similar OEM suppliers and rebranded.
