Description

Professional 3.2L High-Frequency Ultrasonic Cleaner with 120kHz Precision and 0-150W Adjustable Power

The Granbo 3.2L High-Frequency Ultrasonic Cleaner is a professional benchtop bath specifically engineered for ultra-precision cleaning and processing. Operating at a high frequency of 120kHz, this system generates exceptionally fine and dense cavitation bubbles. These microbubbles are highly effective at penetrating micro-grooves, ultra-fine crevices, and blind holes to remove sub-micron particles measuring 1 to 5 microns. Because the physical impact is extremely gentle at 120kHz, the cleaning process prevents surface scratches or micro-fractures on fragile substrates, making it the ideal choice for delicate cuvettes, pipettes, laboratory glassware, and sensitive optical components.

The compact 3.2L capacity tank (inner dimensions: 240 x 135 x 100 mm) is constructed from durable 1.5mm thick SUS304 stainless steel, providing excellent resistance to cavitation erosion over extended periods of use. The system is driven by 3 high-performance transducers delivering up to 150W of adjustable ultrasonic power. It also includes an integrated 300W heating element with an adjustable temperature range of 20°C to 80°C to assist in chemical activation and cleaning efficiency. (Note: The heating function is designed for auxiliary heating and does not feature constant-temperature control).

Advanced Functional Modes for Versatile Laboratory Processing

  • Sweep Mode: Automatically sweeps the frequency by ±1kHz around the 120kHz center frequency to eliminate standing waves, ensuring uniform cavitation distribution throughout the bath and protecting delicate parts from localized energy hotspots.
  • Degas Mode: Employs pulsed ultrasonic intervals to rapidly remove dissolved air and gases from liquids, which is essential for maximizing cavitation efficiency and preparing solvents during solvent degassing.
  • Pulse Mode: Rapidly cycles the ultrasonic power to generate a high-impact blasting effect, helping to dislodge persistent residues from intricate structures.
  • Power Regulation (0-150W): Allows operators to precisely adjust the ultrasonic power density to match the fragility of the workload, preventing damage to sensitive components.

Engineered for Low-Noise and User-Friendly Operation

Operating at 120kHz naturally ensures a much quieter cleaning process compared to low-frequency systems. Combined with Granbo’s multi-layer noise-reduction design, the system minimizes mechanical vibrations and running noise, maintaining a comfortable and quiet laboratory environment. The user interface features a clear digital display for precise timer settings from 1 to 9999 seconds, showing real-time frequency and power. The unit is equipped with a manual drain valve for convenient fluid replacement and comes with a secure wire cleaning mesh basket to protect parts during operation.

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).

Based on Granbo multi-frequency switchable configurations (Single/Dual/Triple/Quad), we recommend:

ProcessRecommended FrequencyApplication Context
Dispersion17-28kHz / 40kHz / 120kHz17-28kHz for coarse solid chunks; 40kHz for powders; 120kHz for micro/nano suspensions.
Emulsification28kHz / 40kHz28kHz generates stronger shear force for heavy liquid blending.
Extraction40kHz / 120kHz120kHz is standard for intracellular substance extraction and cell disruption.
Mixing/Catalysis40kHz / 120kHz40kHz for routine mixing; 120kHz for micro-particle homogenization.
Synthesis80kHz / 120kHzPrevents molecular degradation during material synthesis.
Environmental20kHzHigh-power sonication for sludge treatment, sewage, and algae disruption.

To resist cavitation erosion, Granbo customizes tank thickness and welding based on operating frequency:

Frequency RangeInner Tank (SUS304)Outer ShellCommon 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:

  1. Stage 1 (Pre-cleaning / 28kHz or 40kHz): Strips heavy grease, rust, polishing paste, scale, or coarse metal particles.
  2. Stage 2 (Fine Cleaning / 68kHz or 80kHz): Removes fine particles (5–10μm) from blind holes, threads, and complex internal geometry.
  3. 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:

  1. Visualized Real-time Data: Displays live Power, Frequency, and Current for strict laboratory protocol logging.
  2. High Power Density: Guarantees a standard ≥ 0.3W/cm² for thorough cleaning. Power Density = Ultrasonic Power (W) / Radiating Area (cm²)
  3. 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.
