Granbo 6.5L 200W Multi-Frequency Ultrasonic Cleaner 40–200KHz

Granbo 6.5L 200W Multi-Frequency Ultrasonic Cleaner – 40–200KHz Degas, Sweep & Pulse Modes

Meet the professional-grade cleaning solution for laboratories, clinics, and precision workshops. The Granbo GL0406 Ultrasonic Cleaner delivers 200W of powerful ultrasonic energy across six selectable frequencies (40–200KHz), making it one of the most versatile benchtop cleaning machines available. Whether you need aggressive cavitation for stubborn residue or gentle high-frequency cleaning for delicate components, this machine handles it all with ease.

Key Features

• Six-Frequency Multi-Mode Operation (40 / 68 / 80 / 100 / 120 / 200KHz) – Switch between low frequencies for heavy-duty cleaning and high frequencies for sensitive instruments and precision parts.
• Degas, Sweep & Pulse Modes – Degas mode rapidly removes dissolved air bubbles to maximize cavitation intensity; Sweep mode (±1KHz) ensures uniform cleaning across the entire tank; Pulse mode delivers burst energy for tackling tough contamination.
• 200W Ultrasonic Power + 450W Heating – Combines strong acoustic energy with adjustable heating for thorough cleaning of complex geometries, inner cavities, and blind holes.
• 6.5L Stainless Steel Tank (300×150×150mm) – Generously sized for daily lab or clinical workloads, yet compact enough for benchtop use.
• Digital Control Panel – Precisely set time, temperature, frequency, and operating mode for repeatable, consistent results every cycle.
• Noise-Reduced Design – Internal sound insulation cotton dampens operational noise, enabling comfortable long-duration use in shared workspaces.
• Universal Voltage (110V / 220V) – Ready for use worldwide without adapters.
• CE & RoHS Certified – Meets international safety and environmental compliance standards.

Frequently Asked Questions

Q: What types of items can I clean with this Granbo 6.5L ultrasonic cleaner?

A: This ultrasonic cleaner is designed for a wide range of applications. Its six-frequency range (40–200KHz) makes it suitable for laboratory glassware, dental and surgical instruments, electronic circuit boards, watch and jewelry components, optical lenses, industrial nozzles, and precision mechanical parts. Lower frequencies (40–80KHz) provide stronger cavitation for robust items, while higher frequencies (100–200KHz) deliver gentler action for delicate or sensitive components.

Q: What is the difference between Degas, Sweep, and Pulse modes?

A: Degas mode removes dissolved gases and air bubbles from the cleaning solution before the main cycle, which dramatically increases cavitation efficiency and cleaning effectiveness. Sweep mode continuously modulates the frequency by ±1KHz to ensure uniform distribution of ultrasonic energy throughout the entire tank, eliminating "dead zones." Pulse mode alternates between full power and reduced power in rapid bursts, delivering concentrated energy surges to dislodge stubborn contamination from complex surfaces and inner cavities.

Q: Is this ultrasonic cleaner compatible with both 110V and 220V power supplies?

A: Yes. The Granbo GL0406 supports both 110V and 220V input voltages, making it suitable for use in North America, Europe, Asia, and most other regions worldwide without the need for a voltage converter or transformer.

Q: Can the operating frequency be customized beyond the six preset options?

A: Yes. The Granbo GL0406 supports frequency customization. If you have specific application requirements that fall outside the standard 40/68/80/100/120/200KHz presets, custom frequency configurations can be arranged — contact the vendor for details on bespoke frequency options.
