Supmile KQ-600DB Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-600DB is a benchtop ultrasonic cleaner engineered for consistent, high-efficiency removal of particulate contaminants, organic residues, and thin oxide layers from precision components, laboratory glassware, surgical instruments, and electronic parts. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy is transmitted through an aqueous or solvent-based cleaning medium via piezoelectric transducers bonded to the tank bottom. This generates microscopic vacuum bubbles that rapidly collapse—producing localized shockwaves and microstreaming forces capable of dislodging sub-micron debris without mechanical abrasion. Designed for routine use in QC laboratories, R&D facilities, and maintenance workshops, the KQ-600DB integrates digital microprocessor control with real-time monitoring of critical operational parameters—including actual and set temperature, elapsed time, and power output level—ensuring reproducible cleaning cycles across shifts and operators.

Key Features

• Digital microcontroller-based interface with large LED display showing real-time temperature, timer countdown, power setting (%), and fault status indicators
• Stainless steel (AISI 304) tank and housing—corrosion-resistant, non-porous, and compatible with mild alkaline, acidic, and neutral cleaning solutions
• Adjustable ultrasonic power output (40–100% in 10% steps) to match load density and substrate sensitivity—minimizing erosion risk on delicate optics or soft metals
• Precise digital temperature regulation (10–80 °C ±1.5 °C) via integrated heating element (1000 W) and PT100 sensor feedback loop
• Programmable timer (1–480 minutes) with auto-shutdown and audible end-of-cycle alert
• Comprehensive safety architecture: automatic cutoff on low liquid level, over-temperature, over-current, over-voltage, and dry-run conditions
• Removable stainless steel mesh basket (included) for uniform part suspension and optimized cavitation field exposure
• Manual drain valve located at tank base for rapid solution exchange and residue removal between batches

Sample Compatibility & Compliance

The KQ-600DB accommodates a broad range of sample types—including borosilicate glassware (vials, cuvettes, pipettes), stainless steel tools, aluminum fixtures, ceramic substrates, and printed circuit boards—provided they are chemically compatible with the selected cleaning medium. Its 22.5 L tank volume (500 × 300 × 150 mm internal dimensions) supports batch processing of multiple items while maintaining uniform energy distribution. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device meets general electrical safety requirements per IEC 61010-1 and is routinely deployed in environments adhering to GLP and GMP guidelines when paired with validated cleaning protocols. Users performing regulated cleaning validation (e.g., residual assay preparation per USP or ASTM D2601) must establish and document their own cycle parameters, dwell times, and rinse verification procedures.

Software & Data Management

The KQ-600DB operates as a standalone instrument with no embedded software or network connectivity. All operational data—including setpoints, runtime logs, and fault codes—are displayed in real time but not stored internally or exportable. For audit-trail compliance in regulated settings, users may integrate external logging systems (e.g., USB-connected data loggers or PLC-based SCADA interfaces) to record temperature profiles and cycle timestamps. The unit supports manual documentation workflows aligned with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when used with controlled SOPs and paper/electronic batch records.

Applications

• Routine cleaning of HPLC vials, GC autosampler trays, and spectrophotometer cells prior to trace-level analysis
• Preparation of metallographic samples and SEM stubs by removing polishing compound residues
• Decontamination of reusable surgical instruments in veterinary and academic labs (as adjunct to thermal sterilization)
• Removal of flux residues from PCB assemblies prior to conformal coating or functional testing
• Cleaning of optical lenses, mirrors, and fiber-optic connectors where particle-free surfaces are essential
• Supporting ASTM D1193 Type IV water system maintenance by cleaning feed-line filters and housings

FAQ

Is the KQ-600DB suitable for cleaning delicate MEMS devices or quartz crystals?
Yes—when operated at reduced power (40–60%) and with low-surface-tension, low-foaming solvents (e.g., isopropanol/water blends), it has been successfully used for MEMS wafer cleaning; however, empirical validation is required for each specific device geometry and material stack.
Does the unit include a degassing function?
No—the KQ-600DB does not feature automatic degassing; manual degassing via brief high-power activation (90–120 sec) before loading parts is recommended to remove dissolved air that impedes cavitation efficiency.
Can the heater be disabled while retaining ultrasonic operation?
Yes—temperature control is fully independent; users may set target temperature to “0” or disable heating via front-panel menu to run cold ultrasonic cycles.
What is the expected lifetime of the transducers under continuous daily use?
With proper maintenance (avoiding dry operation, using deionized or filtered water, and periodic descaling), the 40 kHz transducers typically maintain >90% nominal output for 5,000–7,000 operational hours.
Is third-party calibration or certification available for this model?
Supmile provides factory calibration reports upon request; third-party ISO/IEC 17025-accredited calibration services for temperature and timer accuracy can be arranged through authorized metrology partners.
