22L Large Capacity, 40kHz High-Frequency Ultrasonic Cleaning, Deep Cleaning For Glasses, Watches, Jewelry And Medical Equipment. 

1. 40kHz High-Frequency Cleaning: Micron-Level Deep Cleaning

• High-Frequency Cavitation Effect: With a wavelength of 11mm at 40kHz, it generates delicate cavitation bubbles with a diameter of 20-50μm, which can penetrate into 0.1mm narrow gaps (such as the grooves of eyeglass nose pads, the joints of watch straps, and the crevices of jewelry patterns), peeling off 0.5μm-level oil stains, sweat stains, and oxides, ensuring thorough cleaning without any blind spots.
• Exclusive Protection for Precision Items: The high-frequency micro-vibration cleaning provides uniform force, preventing surface scratches caused by traditional brushing (such as the sapphire crystal of watches and the electroplated layers of jewelry). After cleaning, the light transmittance of lenses can be restored to 99.8%, the glossiness of silver jewelry can be increased by 60%, and there will be no scratch residues on the surface of medical equipment.
• Efficient Bactericidal and Anti-Mite Function: It can kill bacteria such as Escherichia coli and Staphylococcus aureus within 30 minutes (bactericidal rate ≥ 99.9%). Meanwhile, it removes mites and their secretions from makeup brushes and shaver heads, safeguarding users' health.

2. 22L Ultra-Large Capacity: Doubling the Efficiency of Batch Cleaning

• Single-Batch Processing Capacity: It can clean 50 pairs of eyeglasses, 30 pieces of jewelry, 20 sets of surgical instruments, or 10 watches (including disassembled strap parts) simultaneously, meeting the peak-hour demands of commercial stores (for example, increasing the daily cleaning volume of eyewear stores by three times).
• Layered Cleaning Basket Design: It is standard-equipped with a detachable 304 stainless-steel cleaning basket (with a 2mm aperture), supporting the classified placement of small items (such as ear studs, screws, and lenses) to avoid collision damage. It is suitable for the disassembled cleaning of multiple components of medical equipment.
• Industrial-Grade Heating Function: The temperature can be adjusted from room temperature to 60°C (with an accuracy of ±2°C). Heating helps dissolve stubborn grease (such as the sludge on watch gears and the protein residues on medical equipment), shortening the cleaning time by 40% compared with the room-temperature mode.
