Supmile KQ-50DA Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-50DA is a compact, microprocessor-controlled benchtop ultrasonic cleaner engineered for precision cleaning tasks in academic, industrial, and quality control laboratories. It operates on the principle of acoustic cavitation—generating high-frequency mechanical vibrations (40 kHz) via piezoelectric transducers bonded to the stainless steel tank base. These vibrations induce controlled microbubble formation and collapse within the cleaning solution, producing localized shockwaves and microstreaming that effectively dislodge particulate contaminants, organic residues, and loosely adhered biofilms from delicate surfaces without mechanical abrasion. Designed for reproducible, non-destructive cleaning of small-volume samples—including glassware, surgical instruments, optical components, PCBs, and analytical sample vials—the KQ-50DA delivers consistent energy delivery across its 2 L working volume, making it suitable for routine maintenance, pre-analytical sample preparation, and light-duty decontamination workflows.

Key Features

• Microcontroller-based digital interface with real-time display of set and elapsed time, power level (%), and operational status indicators
• Stainless steel tank (304 grade) with dimensions 150 × 140 × 100 mm (L × W × H), integrated into a durable engineering plastic housing (overall footprint: 208 × 192 × 225 mm)
• Fixed-frequency 40 kHz transducer system with 50 W nominal output, optimized for broad-spectrum contaminant removal in aqueous and mild solvent-based media
• Continuously adjustable ultrasonic power (40–99% in 1% increments), enabling optimization for sensitive substrates or viscous solutions
• Precision timer with 1–99 minute range and auto-shutdown functionality; retains last-used settings upon power cycle
• Integrated safety protections: over-temperature, over-voltage, and over-current monitoring with visual fault indication
• Includes stainless steel mesh basket for secure sample placement and uniform exposure to acoustic field

Sample Compatibility & Compliance

The KQ-50DA accommodates a wide range of laboratory items up to ~140 mm in width and 100 mm in height. Compatible loads include volumetric flasks, pipette tips, crucibles, watch glasses, filtration membranes, and microcentrifuge tubes. While not certified for sterile processing or regulatory-grade disinfection (e.g., ISO 17664 or AAMI ST33), the unit supports GLP-aligned cleaning validation when used with documented parameters (time, power, bath temperature, and solution composition). Its 220 V / 50 Hz input rating complies with standard Chinese mains specifications; users operating in other regions must verify local voltage compatibility and use appropriate isolation transformers where required. No CE, UL, or FDA 510(k) certification is provided—intended for research-use-only (RUO) applications outside clinical or GMP manufacturing environments.

Software & Data Management

The KQ-50DA operates via embedded firmware without external software dependency. All operational parameters are stored in non-volatile memory and recalled at startup, supporting procedural consistency across shifts and operators. The device does not generate electronic records, export logs, or support audit trail functionality per FDA 21 CFR Part 11 requirements. For laboratories requiring traceable cleaning documentation, manual entry of batch-specific settings (power %, duration, solution type, and lot number) into a validated LIMS or paper-based logbook is recommended. No USB, RS-232, or Ethernet connectivity is available.

Applications

• Routine cleaning of glassware and metal labware prior to calibration or chemical analysis
• Removal of polishing compounds and fingerprints from optical lenses and mirrors
• Preparation of substrates for SEM, TEM, or AFM imaging
• Disaggregation of aggregated nanoparticles in colloidal suspensions
• Assisted extraction of plant metabolites or environmental analytes from solid matrices
• De-gassing of solvents prior to HPLC mobile phase preparation
• Supporting sonication steps in RNA/DNA isolation protocols (non-lytic mode only)

FAQ

Is the KQ-50DA suitable for cleaning delicate electronic components?
Yes—when operated at reduced power (40–60%) and short durations (1–5 min) in low-surface-tension, non-corrosive solvents such as isopropanol or specialized electronics cleaning fluids.
Does the unit include a heater or temperature control?
No. The KQ-50DA lacks integrated heating; bath temperature must be managed externally if thermal enhancement is required.
Can multiple transducers be added to increase cleaning intensity?
No. The unit is configured with a single fixed-position transducer assembly; modification voids warranty and compromises acoustic field uniformity.
What is the expected service life of the transducer under normal use?
With proper maintenance (avoiding dry operation, using compatible solutions, and periodic descaling), the transducer typically maintains >90% nominal output efficiency for ≥5,000 operational hours.
Is a sound-dampening lid available as an accessory?
Not supplied by Supmile; third-party acrylic lids may be used but are not acoustically tuned and may attenuate cavitation efficiency by up to 20%.
