Granbo GL1022 – 22L Multifrequency Ultrasonic Cleaner for Professional & Laboratory Use
The Granbo GL1022 is a high-performance, multi-frequency ultrasonic cleaner engineered for laboratories, industrial workshops, and professional cleaning environments. With a generous 22-litre tank, 500W ultrasonic power, and five selectable frequencies (28 / 40 / 68 / 80 / 120 KHz), this unit delivers thorough, consistent cleaning across a wide range of materials and item sizes — from delicate precision instruments to robust mechanical components.
Why Choose the Granbo GL1022?
- Five Selectable Ultrasonic Frequencies: Switch between 28, 40, 68, 80, and 120 KHz to match the optimal cleaning mode for each material — gentle enough for sensitive optics, powerful enough for heavy-duty industrial parts.
- 500W Ultrasonic Power + 1000W Heating: Dual power systems ensure rapid temperature rise and sustained, deep-penetrating cavitation for efficient removal of oils, oxides, biological residues, and more.
- Large 22L Tank (500 × 300 × 150 mm): Accommodates large lab equipment, circuit boards, medical instruments, and industrial components with ease.
- Pulse Mode Support: Pulsed operation intensifies cavitation bursts for stubborn soiling without continuous maximum output.
- Sweep Frequency (±1 KHz): Frequency sweeping eliminates standing waves and ensures uniform cleaning across the entire tank.
- Mute Design: Built-in sound insulation cotton significantly reduces operational noise — ideal for shared laboratory and workshop environments.
- Dual Voltage (110V / 220V): Compatible with global power standards for worldwide use.
- CE & RoHS Certified: Meets international electrical safety and environmental compliance standards.

Frequently Asked Questions
Q: What are the five ultrasonic frequencies and when should I use each?
A: The Granbo GL1022 supports 28, 40, 68, 80, and 120 KHz. Lower frequencies (28–40 KHz) generate stronger cavitation and are best suited for harder, more robust items such as metal parts, engine components, and industrial tooling. Mid-range frequencies (68–80 KHz) work well for circuit boards, electronic assemblies, and lab equipment. The highest frequency (120 KHz) produces finer, gentler cavitation ideal for delicate surfaces such as optical lenses and precision sensors.
Q: Is the GL1022 suitable for continuous laboratory operation?
A: Yes. The unit is designed for professional and laboratory environments. Its 1000W heating element, 500W ultrasonic transducers, sound insulation cotton muting system, and CE/RoHS certification all indicate suitability for sustained, demanding use. Always follow recommended fill levels and observe the steam duration guidelines (10–15 minutes) for best results.
Q: What voltage does this ultrasonic cleaner support?
A: The Granbo GL1022 supports both 110V and 220V, making it compatible with power outlets in North America, Europe, Asia, and most other regions worldwide.
Q: Can I customise the ultrasonic frequency for my specific application?
A: Yes — frequency customisation is supported. Contact the manufacturer or your supplier to discuss specific frequency configurations beyond the standard 28/40/68/80/120 KHz preset options if your application requires it.
