Description
Acoustic Dynamics and Surface Safety of 40kHz Cavitation
Operating at an acoustic frequency of 40kHz (sound wavelength λ ≈ 36.2 mm), this ultrasonic system generates millions of uniform cavitation micro-bubbles that release balanced kinetic energy upon collapse. Powered by four industrial-grade 50W transducers (200W total output), it delivers thorough micro-scrubbing without causing pitting or micro-fractures on hard substrates.
- Micron-Scale Contaminant Removal: Effectively strips oil films, shop grit, polishing residue, and particles down to 10μm, excelling at non-abrasive Cutting Dust Removal from edges and flute channels.
- Complex Geometry Penetration: Reaches deep inside narrow crevices, tapping threads, and cross-drilled passages on Long Metal Tools, Machined Castings, and Threaded Fasteners.
- Material-Safe Agitation: Provides dependable results for stainless steel, tool alloys, titanium, ceramics, and technical resins, ensuring consistent Hardware Cleaning while facilitating physical processes such as Powder Dispersion.
Elongated 300mm Profile and 4.5L Tank Utility
Engineered with an internal tank dimension of 300 × 150 × 100 mm (L × W × H), the elongated 4.5L capacity architecture is tailored for wide-footprint workpieces and multi-piece batch sonication.
- Extended Item Clearance: The 300mm horizontal span comfortably accommodates elongated items such as Long Metal Tools, medical probes, surgical forceps, and Dental Instruments horizontally without mechanical obstruction.
- Component Batch Agitation: Allows side-by-side arrangement of Machined Castings, Automotive Valves, and Machined Metal Parts within the included protective wire mesh basket for complete liquid immersion.
- Sonochemical Agitation Support: The shallow, wide bath surface promotes rapid degassing and liquid-phase energy distribution for fluid Powder Dispersion and sample prep workflows.
Thermal Efficiency and Heavy-Duty Electronic Control
- 0–200W Linear Ultrasonic Regulation: Enables fine power tuning to protect delicate Dental Instruments or deliver maximum power for intensive Hardware Cleaning on Machined Metal Parts.
- Room Temperature to 80°C Heating System: Thermally accelerates surfactant activity, dissolving solidified grease and assisting in localized Rust Removal on Machined Castings and Threaded Fasteners.
- 1–9999s Wide Digital Timing Range: Accommodates quick spot-cleans as well as extended, continuous sonication runs on stubborn Automotive Valves and Long Metal Tools.
- Deep-Drawn SUS304 Stainless Steel Construction: High-grade, cavitation-resistant stainless steel inner tank ensures corrosion resistance against mild acids, alkalis, and industrial solvent agents during rigorous Rust Removal and Cutting Dust Removal.

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.
