Supmile KQ3200DB Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ3200DB is a benchtop ultrasonic cleaner engineered for precision cleaning, degassing, dispersion, and sample preparation in academic, industrial, and quality control laboratories. It operates on the principle of high-frequency acoustic cavitation—generating micro-bubbles in liquid media that collapse with localized energy release, effectively dislodging particulate contaminants from surfaces of immersed objects. With a nominal frequency of 40 kHz and a digitally regulated output power of 150 W (adjustable between 40% and 100%), the unit delivers consistent energy distribution across its 6-liter stainless steel tank. Its integrated heating system (0–80 °C) enables temperature-assisted cleaning protocols, while real-time digital monitoring of bath temperature, power level, elapsed time, and water level ensures process repeatability and operator safety. Designed for routine use in ISO/IEC 17025-accredited labs and GMP-compliant environments, the KQ3200DB supports method validation and documentation requirements through stable parameter retention and built-in safety interlocks.

Key Features

• Microprocessor-controlled operation with digital display of time, temperature, power level, and real-time water level
• Automatic frequency sweeping circuitry enhances transducer efficiency and minimizes harmonic distortion, improving cleaning uniformity and extending component lifespan
• 304 stainless steel tank (300 × 150 × 150 mm internal dimensions) resistant to corrosion and compatible with aqueous and mild solvent-based cleaning solutions
• Four-stage safety protection: low-water-level cutoff, over-temperature shutdown, over-voltage monitoring, and over-current detection
• Adjustable ultrasonic power (40–100% in 10% increments) and programmable timer (1–480 minutes) allow optimization for delicate optics, precision instruments, or robust metal parts
• Manual hinged lid with acoustic damping design reduces ambient noise and prevents solution splashing during operation
• Integrated 400 W heating element with ±1 °C temperature stability supports enzymatic decontamination, solvent evaporation control, and viscosity-sensitive cleaning applications

Sample Compatibility & Compliance

The KQ3200DB accommodates a broad range of laboratory items including glassware (vials, cuvettes, pipette tips), metallic components (surgical tools, calibration standards), ceramic substrates, and polymer-based fixtures. Its non-aggressive cavitation profile at 40 kHz is suitable for fragile samples such as MEMS devices, optical lenses, and printed circuit boards—provided appropriate cleaning solutions (e.g., alkaline, neutral, or ethanol-based formulations) are selected per material compatibility guidelines. The device complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, it supports GLP-aligned workflows when operated under documented SOPs—including audit-ready parameter logging via external data loggers.

Software & Data Management

The KQ3200DB operates via embedded firmware without proprietary software dependency. All operational parameters—including setpoint temperature, power percentage, timer duration, and real-time sensor feedback—are retained in non-volatile memory after power cycling. Though the unit lacks USB or Ethernet connectivity, its digital interface supports manual entry of repeat protocols, enabling consistent execution across shifts. For laboratories requiring electronic records, integration with external PLCs or SCADA systems is feasible via optional analog voltage outputs (0–5 V) for temperature and timer status signals. Data integrity aligns with ALCOA+ principles when paired with validated environmental monitoring systems and procedural controls for traceability.

Applications

• Routine cleaning of HPLC vials, GC injectors, and spectrophotometer cells prior to analysis
• Removal of polishing residues from semiconductor wafers and photomasks
• Extraction of metabolites or nucleic acids from biological tissues using sonication-assisted lysis
• Deagglomeration of nanoparticle suspensions for DLS or TEM sample preparation
• Pre-cleaning of calibration weights and metrology artifacts in accredited measurement labs
• Supporting ASTM D2621 (cleaning verification of automotive parts) and ISO 14644-1 (cleanroom component preparation) workflows

FAQ

Is the KQ3200DB suitable for cleaning delicate optical components?
Yes—when operated at reduced power (40–60%) and with deionized water or low-surfactant solutions, it effectively removes submicron particles without surface pitting or coating damage.
Does the unit support continuous operation mode?
No—the maximum timer setting is 480 minutes; however, sequential cycles can be initiated manually to achieve extended treatment durations.
Can the heater be disabled while maintaining ultrasonic function?
Yes—temperature control is fully independent; users may set the heater to “OFF” while running ultrasonic cleaning at ambient temperature.
What maintenance is required for long-term reliability?
Routine cleaning of the tank interior with mild detergent, periodic inspection of the transducer mounting seal, and replacement of the mesh basket if deformation or corrosion is observed.
Is the KQ3200DB compliant with CE marking requirements?
It meets essential requirements of the EU Electromagnetic Compatibility Directive (2014/30/EU) and Low Voltage Directive (2014/35/EU); however, formal CE certification documentation must be obtained from the authorized distributor for regulatory submission purposes.
