Description
Gentle 68kHz Ultrasonic Energy for Micro-Grooves & Delicate Components
Operating at a high frequency of 68kHz, this cleaner generates ultra-fine, highly dense cavitation bubbles engineered for delicate substrates and fine internal structures. It effectively removes 5–10μm fine particles, light oil films, and soft residues from narrow crevices and micro-grooves. By minimizing harsh physical impact, it preserves sensitive surfaces, making it suitable for Optical Components, Dental Instruments, printed circuit boards, and precision Laboratory Glassware.
30L Capacity Tank for Beakers, Flasks & Large Batch Cleaning
Featuring a spacious internal bath measuring 500 × 300 × 200 mm with a 30L capacity, this unit comfortably fits oversized laboratory items including Burettes, Pipettes, volumetric Flasks, and multiple Glass Beakers. Constructed with a 1.5mm thick SUS304 stainless steel inner tank and a 1.0mm SUS304 outer housing, it incorporates a sturdy wire mesh basket and built-in drain valve to facilitate routine Beaker Sample Preparation and regular Batch Sonication workflows.
0–800W Adjustable Ultrasonic Power & 1000W Heating System
Equipped with 16 transducers (50W each), the bath provides 0–800W adjustable ultrasonic power to customize energy density according to item sensitivity. An independent 1000W heating power system elevates liquid temperatures between 20°C and 80°C to assist dirt breakdown (note: process heating, non-thermostatic constant temperature control). A digital timer allows precise operational timing from 1 to 9999 seconds.
English Digital Control Panel: Degas, Sweep, Pulse & Low Noise
The English digital interface gives operators full control over specialized processing functions for lab tasks and general Instrument Cleaning:
- Degas Mode: Delivers pulsed ultrasonic bursts to purge air bubbles from liquids, suitable for HPLC Solvent Degassing and fluid sample preparation.
- Sweep Mode: Modulates the central frequency within ±1kHz to dissipate standing waves and promote uniform cavitation across the entire tank.
- Pulse Mode: Rapidly alternates power between 100% and 0% to supply targeted bursting action against stubborn surface residues.
- Noise Reduction: The high-frequency 68kHz cavitation design maintains mechanical operating sound levels below 80dB for quiet operation.
Box Contents:
- 1 x Professional Ultrasonic Cleaner
- 1 x Durable Mesh Cleaning Basket
- One cover, one power cord, one manual warranty card certificate of conformity.
Packing type:
- One unit filled with thick foam, then standard export corrugated carton or wooden box.

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.
