Description
19L Deep-Tank 33kHz Ultrasonic Cleaning Bath for Industrial Components & Liquid Processing
Equipped with eight 50W transducers generating 400W adjustable ultrasonic power, this 19L benchtop ultrasonic cleaner operates at a robust 33kHz center frequency. Built with a deep stainless steel tank measuring 33 x 30 x 20 cm, an integrated heater adjustable from room temperature to 80°C, and a digital timer (1–9999s), this system excels at heavy-duty scrubbing and high-volume fluid manipulation.
Advantages of 33kHz Mid-Frequency Sonication
- Aggressive Cavitation Scrubbing: The 33kHz frequency produces larger cavitation bubbles with higher implosion impact than standard 40kHz units, providing energetic degreasing for removing scale buildup, thick oil films, polishing paste, and cutting dust removal.
- High Shear Kinetic Energy for Fluids: Generates powerful fluid shear stress ideal for particle breakdown, enabling efficient coarse powder dispersion, solution extraction, cell extraction, and solvent degassing.
- Protective Substrate Handling: Delivers robust scrubbing power while preventing intense surface pitting on machined metal parts and resin moldings compared to ultra-low 28kHz systems.
19L Tank Capacity & Suitable Cleaning Applications
The 20 cm deep, 19L tank capacity provides ample volumetric space for immersing taller fixtures, longer assemblies, and multi-beaker liquid setups.
- Heavy Hardware & Engine Components: Accommodates engine blocks, gearboxes, valves, bolts, screws, and hardware tools.
- Long Tooling & Deep Components: Deep bath geometry allows full submersion of machined castings, machining parts, and extended mechanical fittings.
- Resin & Molded Products: Removes flash lines and resin parts contaminants without damaging critical dimensions.
- Volumetric Liquid Containers: Holds large laboratory glassware, tall burettes, condenser tubes, flasks, and multiple glass beakers for uniform processing.

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.
