Description
25kHz Mechanical Cavitation & High-Impact Advantages
- Violent Acoustic Cavitation: Operating at 25kHz creates larger cavitation bubbles that implode with intense physical shockwaves, ideal for stripping heavy grease, stubborn rust, baked-on scale, and polishing wax from tough industrial substrates.
- High-Shear Force Processing: The aggressive acoustic streaming of 25kHz delivers massive kinetic energy needed for rapid liquid emulsification, particle dispersion, and slurry mixing in liquid phase workflows.
14L Capacity & Heavy-Duty Tank Construction
- 14L Versatile Capacity: Provides an expansive bath size capable of soaking mid-sized industrial assemblies, engine parts, gearboxes, resin mold plates, and hardware tools.
- 2.0mm SUS304 Tank with Heavy Welding: Built with an ultra-thick 2.0mm SUS304 stainless steel inner bath and welded using manual oxy-acetylene heavy welding to endure severe 25kHz cavitation erosion over long operating cycles.
Targeted Cleaning & Processing Applications
- 1. Automotive & Heavy Machinery Maintenance:
Deep cleans heavy engine parts, gearboxes, carburetors, fuel injectors, pistons, and cast iron valves encrusted with heavy grease and carbon buildup. - 2. Hardware Tools, Tooling & Molds:
Effortlessly removes cutting dust, resin burrs, polishing wax, and scale from hardware tools, cutting tools, stainless steel fittings, and durable plastic components. - 3. Severe Surface Stripping & Scale Removal:
Rapidly disintegrates heavy rust, oxidation layers, stubborn scale, and polishing wax from rugged metal hardware. - 4. Liquid Agitation & High-Shear Sonochemistry:
- Emulsification & Homogenization: Accelerates liquid emulsification and homogenization in high-viscosity fluids and liquid chemical mixtures.
- Dispersion & Mixing: Enhances particle dispersion, slurry mixing, and fluid mixing across industrial processing setups.
- Degassing & HPLC Prep: Purges trapped air and dissolved gas from liquids and mobile phases prior to HPLC analysis.
Advanced Control Modes (Sweep, Pulse & Degas)
- 0–400W Adjustable Power: Stepless 0–400W adjustment provides flexible energy density for delicate fluid mixing or intense rust removal.
- Sweep Mode: Prevents standing waves to ensure uniform ultrasonic energy distribution across the entire 14L bath.
- Pulse Mode: Generates continuous peak power bursts to break down thick rust and hard stubborn scale.
- Degas Mode: Expels trapped air pockets to optimize cavitation impact and degassing workflows.

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:
Granbo Recommended Frequency Matrix:
• 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).
• 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:
Wavelength (λ) = 1,450,000 (mm/s) / Frequency (Hz)
- 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.
