Description
Optimal Cavitation Dynamics of Balanced 40kHz Ultrasound
Operating at the versatile frequency of 40kHz (wavelength λ ≈ 36.2 mm), this ultrasonic unit delivers the ideal equilibrium between mechanical scrubbing force and delicate surface protection. Driven by three industrial 50W piezo transducers (150W total output), it provides comprehensive acoustic agitation across the entire fluid bath.
- Micron-Scale Contaminant Stripping: Dislodges particles greater than 10μm, polishing pastes, shop debris, and lubricating residues from intricate contours without eroding soft alloys, ceramics, or glass substrates.
- Complex Geometry Scrubbing: Seamlessly reaches recessed channels, blind holes, and internal threads on Hardware Tools, Machined Metal Parts, and Threaded Fasteners where conventional mechanical scrubbing fails.
- Surface-Safe Cleansing: Provides an effective balance that prevents surface micro-pitting, making it well suited for routine Degreasing, fine Rust Removal, and the maintenance of precision Cutting Tools.
Deep 15cm Profile and 4.8L Capacity for Taller Workpieces
Featuring an extended tank interior of 240 × 135 × 150 mm (L × W × H), the 4.8L capacity design provides additional vertical immersion depth compared to standard shallow benchtop cleaners.
- Tall Vessels & Submerged Fixtures: The 15cm immersion depth allows complete fluid submersion for taller Laboratory Glassware, tall beakers, and volumetric flasks, supporting uniform Solvent Degassing and accelerated Sample Homogenization.
- Engine & Tool Components: Easily accommodates vertical placement of Hardware Tools, Automotive Valves, long Cutting Tools, and complex Machined Metal Parts within the protective wire mesh basket.
- High Cavitation Energy Density: Concentrated acoustic power across the 4.8L volume ensures intensive liquid transmission for ultrasonic-assisted dissolution, chemical Degreasing, and light Rust Removal.
Industrial Precision Control & Thermal Management
- 0–150W Linear Power Adjustment: Gives operators full control to dial down power for delicate Laboratory Glassware or ramp up to 150W full cavitation for heavy Machined Metal Parts and Automotive Valves.
- Room Temperature to 80°C Heating: Optimizes cleaning chemical activation and liquefies heavy grease, boosting the speed of component Degreasing and surface Rust Removal.
- 1–9999s Broad Digital Timer: Enables unattended, continuous processing cycles for automated industrial wash cycles and time-intensive Sample Homogenization.
- SUS304 Deep-Drawn Stainless Steel Tank: Seamless, heavy-duty stainless construction resists cavitation pitting and chemical oxidation over extended duty cycles.

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.
