Description

High-Capacity Dual-Frequency Cleaning

This powerful ultrasonic cleaner features a switchable dual-frequency of 40/68kHz, making it highly effective for both heavy-duty and precision cleaning applications. Driven by 8 high-performance transducers, the system delivers a robust ultrasonic output that is fully adjustable from 0 to 400W (0-400W Adjustable). The 40kHz frequency provides aggressive cavitation to strip stubborn grease, carbon deposits, and industrial oils, while the 68kHz setting provides a gentle, high-density wash to clean intricate geometries and blind holes without damaging delicate surfaces.

Advanced Digital Functions for Lab and Industry

The user-friendly digital interface allows precise control over operations. The digital timer can be programmed from 1 to 9999 seconds, making it suitable for long-duration cleaning and sample preparation. It features essential laboratory modes including Degas mode to eliminate air bubbles for maximum cavitation efficiency, Sweep mode to distribute ultrasonic waves evenly and prevent hot spots, and Pulse mode for high-impact cleaning of tenacious residues. A Semiwave mode is also available for delicate parts.

Large Tank Capacity and High-Power Heating

Equipped with a spacious 10L stainless steel tank measuring 300x240x150 mm (unit size 325x265x340 mm), this model easily accommodates larger instruments and batch cleaning tasks. It features a powerful 600W heating system with an adjustable temperature range of 20°C to 80°C to accelerate the breakdown of grease and binders (note: the heating function does not feature constant temperature control). The unit is housed in a robust, low-noise structure designed to reduce operating sound in lab environments.

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.
