Overview
The Supmile KQ-50ES is a compact, general-purpose benchtop ultrasonic cleaner engineered for routine laboratory cleaning tasks requiring consistent cavitation energy and thermal stability. It operates on the principle of piezoelectric transduction—converting high-frequency electrical signals (40 kHz) into mechanical vibrations transmitted through the cleaning solution. These vibrations generate controlled micro-cavitation bubbles that collapse near submerged surfaces, producing localized shockwaves and micro-jets effective at dislodging particulate contaminants, organic residues, and loosely adhered biofilms from delicate instruments, glassware, and precision components. Designed for environments where reliability, ease of operation, and regulatory traceability are essential—including QC labs, academic research facilities, and small-scale manufacturing support labs—the KQ-50ES delivers reproducible cleaning performance without complex software interfaces or network dependencies.
Key Features
- Robust 304 stainless steel tank construction ensures long-term corrosion resistance against aqueous and mild solvent-based cleaning solutions.
- Integrated 40 kHz ultrasonic generator with automatic frequency sweeping minimizes standing wave formation and improves acoustic field uniformity across the 2 L tank volume.
- Dual-function analog control panel enables independent adjustment of heating (ambient to 80 °C) and timing (1–30 minutes), supporting both cold sonication and thermally assisted cleaning protocols.
- 100 W built-in heating element provides stable temperature maintenance within ±2 °C accuracy under standard load conditions, facilitating standardized cleaning per ASTM D4296 or ISO 13857 methodologies.
- Acoustic lid reduces ambient noise by ≥15 dB(A) and prevents solvent evaporation during heated operation—critical for maintaining solution concentration integrity over extended cycles.
- High-efficiency power conversion architecture achieves >85% electroacoustic coupling efficiency, minimizing reactive power draw and thermal loading on internal electronics.
Sample Compatibility & Compliance
The KQ-50ES accommodates a wide range of labware including volumetric flasks, pipette tips, crucibles, microscope slides, and small metal parts up to 140 mm in width. Its 150 × 140 × 100 mm inner tank permits vertical immersion of most standard-length tools while retaining adequate solution depth for effective cavitation propagation. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity standards). While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, it supports GLP-aligned documentation when used with validated cleaning SOPs and manual logbook entries for time, temperature, and cycle count.
Software & Data Management
The KQ-50ES employs an analog control system with no embedded firmware or digital connectivity. All operational parameters are set manually via rotary dials and monitored using integrated LED indicators. This architecture eliminates cybersecurity risks associated with IoT-enabled devices and ensures uninterrupted functionality in electromagnetically noisy environments. For laboratories requiring audit trails, users may integrate external data loggers (e.g., calibrated thermocouple + timer) connected to validated spreadsheet templates compliant with ALCOA+ principles. No proprietary software or driver installation is required.
Applications
- Routine decontamination of HPLC vials, syringe filters, and autosampler components prior to analytical runs.
- Preparation of sample holders and electrodes for electrochemical testing to remove adsorbed organics and oxide layers.
- Cleaning of optical components—including lenses and cuvettes—without surface abrasion or coating damage.
- Removal of flux residues from PCB prototypes and soldering fixtures in electronics R&D labs.
- Supporting ASTM E1667-compliant validation studies for cleaning process qualification in non-sterile pharmaceutical manufacturing settings.
FAQ
Is the KQ-50ES suitable for cleaning delicate MEMS devices or silicon wafers?
Yes—when operated at lower time settings (1–5 min) and without heating, the 40 kHz frequency provides gentle yet effective particle removal. However, use only low-surface-tension, non-ionic aqueous cleaners; avoid alcohols or acetone unless compatibility has been verified.
Can the unit be operated continuously for multiple cycles without cooldown?
The device includes thermal protection circuitry that automatically suspends heating if internal temperatures exceed safe thresholds. Continuous ultrasonic operation beyond 30 minutes requires ≥10-minute rest intervals to maintain transducer longevity and signal stability.
Does the mesh basket affect ultrasonic energy distribution?
The included 304 stainless steel basket is acoustically transparent at 40 kHz and positioned to minimize shadowing. For maximum energy transfer, ensure parts do not contact tank walls or the basket base during operation.
Is calibration documentation available for this model?
Supmile provides factory calibration certificates for temperature and timer accuracy upon request. Users are responsible for periodic verification using NIST-traceable thermometers and stopwatch standards per ISO/IEC 17025 guidelines.
