Description
High-Efficiency Dual-Frequency Performance
This high-efficiency cleaning system utilizes a switchable dual-frequency of 40/80kHz to deliver targeted cleaning action. The 40kHz frequency provides the mechanical force needed to dislodge common grease, dust, and light rust, while the 80kHz frequency is optimized for gentle cleaning of complex surfaces and micro-grooves. Driven by 16 high-performance transducers, the system provides an adjustable ultrasonic power range of 0 to 800W, ensuring you can tailor the energy density to your specific parts. Both the tank and housing are made of premium SUS304 stainless steel.
Advanced Digital Control Suite
The user-friendly interface allows for precise adjustments of the cleaning cycle. The digital timer can be set from 1 to 9999 seconds for continuous or batch processing. Key features include Degas mode to eliminate air bubbles that damp ultrasonic energy, Sweep mode to prevent hot spots and standing waves, and Pulse mode for high-impact cleaning. The Semiwave function offers a gentler wave profile for fragile items.
Efficient Heating and Robust Tank Design
The unit features a 22L capacity tank with dimensions of 500x300x150 mm and unit size of 530x330x335 mm. It is equipped with 1000W heating power, capable of warming the bath from 20°C to 80°C to assist in loosening grease and binders. Note that the heating system operates without constant temperature control. The structure is built to incorporate noise reduction characteristics, ensuring a quieter workspace.

Support & FAQ
Frequency determines cavitation bubble size, impact force, and penetration depth. Lower frequencies produce violent impact for heavy dirt, while higher frequencies provide dense, gentle cleaning for sub-micron microstructures:
• 28kHz: Heavy oil, scale, rust, polishing wax, cutting dust, and thick contaminants (>10μm) on heavy metal/resin parts.
• 40kHz: Universal choice for standard labware, stainless steel, glass, and general maintenance (>10μm particles).
• 68kHz / 80kHz: Fine cleaning for PCBs, watch components, optics, medical instruments, and micro-grooves (5–10μm particles).
• 120kHz: Precision cleaning for micro-blind holes (<0.1mm), semiconductors, ICs, optical lenses, and MEMS (1–5μm particles).
• 200kHz: Ultra-precision cleaning for silicon wafers, MEMS, thin films, and sub-micron / nano-scale contamination (<1μm).
Based on Granbo multi-frequency switchable configurations (Single/Dual/Triple/Quad), we recommend:
| Process | Recommended Frequency | Application Context |
|---|---|---|
| Dispersion | 17-28kHz / 40kHz / 120kHz | 17-28kHz for coarse solid chunks; 40kHz for powders; 120kHz for micro/nano suspensions. |
| Emulsification | 28kHz / 40kHz | 28kHz generates stronger shear force for heavy liquid blending. |
| Extraction | 40kHz / 120kHz | 120kHz is standard for intracellular substance extraction and cell disruption. |
| Mixing/Catalysis | 40kHz / 120kHz | 40kHz for routine mixing; 120kHz for micro-particle homogenization. |
| Synthesis | 80kHz / 120kHz | Prevents molecular degradation during material synthesis. |
| Environmental | 20kHz | High-power sonication for sludge treatment, sewage, and algae disruption. |
To resist cavitation erosion, Granbo customizes tank thickness and welding based on operating frequency:
| Frequency Range | Inner Tank (SUS304) | Outer Shell | Common Tank Capacities & Process |
|---|---|---|---|
| 28kHz - 200kHz | 1.5 mm Thickness | SUS304 (1.0 mm) | 3–10L, 14–22L, 30–58L, 61–135L. Industrial precision stamping & TIG welding. |
| 25kHz | 2.0 mm Thickness | SUS201 (1.0 mm) | Thickened tank; Manual oxy-acetylene heavy welding. |
| 17kHz & 20kHz | 3.0 mm Thickness | SUS201 (1.0 mm) | Ultra-thickened tank; Manual oxy-acetylene heavy welding. |
*Material Safety Tip: Soft metals (aluminum, brass, gold) and delicate glass/ceramics may scratch or fracture at 28kHz. We recommend 40kHz to 80kHz or pre-testing for delicate substrates.
When a workpiece has both stubborn contaminants and sub-micron precision requirements, use a multi-stage approach:
- Stage 1 (Pre-cleaning / 28kHz or 40kHz): Strips heavy grease, rust, polishing paste, scale, or coarse metal particles.
- Stage 2 (Fine Cleaning / 68kHz or 80kHz): Removes fine particles (5–10μm) from blind holes, threads, and complex internal geometry.
- Stage 3 (Ultra-Precision Rinse / 120kHz or 200kHz): Eliminates sub-micron (<1μm) residues without damaging fragile surfaces or thin films.
- Sweep Mode: Automatically sweeps ±1kHz around the center frequency to eliminate standing waves, ensuring uniform cavitation across the bath.
- Degas Mode: Uses pulsed ultrasound intervals (e.g., 5s on / 5s off) to purge dissolved air/gas from liquids—crucial for HPLC sample prep and max cavitation efficiency.
- Pulse Mode: Rapidly cycles power from 100% to 0% to produce a "blasting" impact that removes tough or baked-on residues.
Granbo units utilize Full-Bridge Separately Excited PCB Driver Boards rather than cheap self-excited circuits:
- Visualized Real-time Data: Displays live Power, Frequency, and Current for strict laboratory protocol logging.
- High Power Density: Guarantees a standard ≥ 0.3W/cm² for thorough cleaning. Power Density = Ultrasonic Power (W) / Radiating Area (cm²)
- Low Noise Operation: While 28kHz operation naturally produces more audible mechanical noise, Granbo's multi-layer noise-reduction design enables high-frequency units (≥68kHz) to operate at noise levels below 80dB.
Ultrasonic frequency determines sound wavelength and cavitation bubble collapse intensity:
- 20kHz (λ ≈ 72.5mm): Large bubbles, high collapse force. Best for heavy rust, sludge, and thick scale.
- 40kHz (λ ≈ 36.2mm): Medium bubbles. Ideal balance between cleaning power and component safety.
- 120kHz (λ ≈ 12.0mm): Micro bubbles. High penetration depth for sub-micron cracks and fragile silicon/semiconductor parts.
Beaker Size Matching:
• Beaker ≤ 500mL → 3.2L to 6.5L Tank.
• Beaker ≥ 800mL → 10L to 30L Tank (10L is the most popular size for general lab applications).
Temperature Management:
Ultrasonic activity inherently raises liquid temperature. Although Granbo heating goes up to 80°C, cavitation effectiveness drops significantly above 72°C–80°C due to increased vapor pressure. For temperature-sensitive or low-temp processes, use cooling coils or ice packs in the bath.
Standard production lead times for out-of-stock or customized Granbo models:
- 28kHz - 200kHz Models (Single, Dual, Triple, Quad Frequency): 3 - 5 business days for shipping.
- Ultra-Low Frequency (17kHz, 20kHz, 25kHz): 14 - 20 business days for shipping.
*Note: Customizations like RS-485 communication or PLC integration may slightly adjust delivery timelines. Contact us for precise scheduling.
