Overview
The HengAo HU6150D Digital Ultrasonic Cleaner is a benchtop general-purpose cleaning system engineered for precision and reproducibility in academic, pharmaceutical, and industrial laboratory environments. It operates on the principle of ultrasonic cavitation: high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers bonded to the stainless steel tank bottom induce rapid formation and collapse of microscopic vacuum bubbles in the cleaning medium. This implosive energy disrupts particulate adhesion, removes organic residues, and facilitates degassing—without mechanical abrasion or thermal degradation of delicate components. Designed for routine use in sample preparation workflows, the HU6150D integrates digital control logic with robust electromechanical architecture to support consistent cleaning performance across diverse solvent systems including aqueous detergents, ethanol, acetone, and specialized formulations.
Key Features
- Digital microprocessor-controlled interface with real-time display of time, temperature, and power level—enabling precise parameter replication across experiments.
- Adjustable ultrasonic power output (0–100% in 10% increments), allowing optimization for sensitive substrates (e.g., optical lenses, microfluidic chips) or heavily soiled instrumentation parts.
- Programmable heating function (ambient to 95 °C ±2 °C accuracy), supporting thermally enhanced cleaning protocols aligned with ASTM D2621 and ISO 13485-compliant processes.
- Stainless steel tank (6 L usable volume) constructed from imported brushed 304-grade stainless steel—resistant to corrosion from halogenated solvents and alkaline detergents over extended service life.
- Integrated degas mode: automatically reduces dissolved gas content in solvents prior to cleaning cycles, improving cavitation efficiency and reducing surface pitting risk on polished metals.
- Manual drain valve located at tank base for controlled fluid exchange—compatible with GLP documentation requirements for solvent change logs and cross-contamination mitigation.
Sample Compatibility & Compliance
The HU6150D accommodates a broad range of sample geometries and material classes, including glassware (vials, cuvettes, pipette tips), metal instruments (tweezers, forceps, surgical tools), ceramic substrates, and polymer-based labware. Its open-top configuration permits immersion of irregularly shaped objects up to 240 × 150 × 120 mm (L×W×H). The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. While not certified for Class II biological safety applications, it supports cleaning steps within ISO 17025-accredited testing laboratories when operated per validated SOPs. For regulated environments (e.g., FDA-regulated QC labs), users may implement audit-trail-capable external logging for time/temperature/power parameters.
Software & Data Management
The HU6150D operates via embedded firmware without external PC dependency. All operational parameters are stored in non-volatile memory and retained after power cycling. Though no native data export interface is provided, the device supports integration into centralized lab management systems via optional RS-232 or analog voltage output modules (sold separately). Time-stamped cycle records can be manually logged to meet basic GLP traceability requirements. Firmware updates are performed via USB port using manufacturer-provided utilities—version history and update logs are maintained per internal quality documentation protocols.
Applications
- Pre-analytical sample preparation: removal of residual proteins, lipids, or salts from HPLC vials, autosampler needles, and electrophoresis equipment.
- Materials science: cleaning of SEM/TEM sample stubs, sputter targets, and thin-film deposition fixtures to minimize particulate-induced defects.
- Medical device manufacturing: pre-sterilization cleaning of stainless steel and titanium components per ISO 13485 Annex C guidelines.
- Academic research: extraction assistance for plant metabolites, cell lysate clarification, and nanoparticle dispersion stabilization.
- Calibration lab maintenance: decontamination of reference standards, weights, and gauge blocks without dimensional alteration.
FAQ
Is the HU6150D suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at ≤30% power and low temperatures (≤40 °C) with low-surface-tension solvents such as isopropanol, the unit delivers gentle yet effective cleaning without micro-scratching or stiction-induced damage.
Can the unit be used with flammable solvents?
Only in well-ventilated fume hoods with explosion-proof electrical certification; the HU6150D lacks intrinsic safety rating per ATEX or UL 1203. Users must conduct site-specific hazard assessments before solvent selection.
Does the device support continuous operation?
Maximum recommended duty cycle is 60 minutes ON / 20 minutes OFF to prevent transducer overheating and ensure long-term stability of frequency output.
What maintenance is required?
Monthly inspection of tank integrity, transducer bonding, and drain valve sealing; annual calibration of temperature sensor against NIST-traceable reference thermometer.
Is validation documentation available?
Factory test reports (including frequency sweep verification and power output linearity) are supplied with each unit. IQ/OQ protocols compatible with GMP environments are available upon request.
