Supmile KQ-500DV Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-500DV is a general-purpose 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—generated by piezoelectric transducers bonded to the stainless steel tank bottom—at a fixed frequency of 40 kHz. This frequency balances penetration depth and micro-cavitation intensity, making it suitable for removing particulate contaminants, organic residues, and loosely adhered biofilms from glassware, metal parts, optical components, and laboratory instrumentation without mechanical abrasion. The unit integrates a digitally controlled heating system (ambient to 80 °C), enabling temperature-assisted cleaning protocols aligned with ASTM D2616 and ISO 13485-compliant processes. Its robust 304 stainless steel construction, sealed tank design, and integrated safety interlocks ensure long-term operational stability and compliance with basic laboratory equipment safety standards (IEC 61010-1).

Key Features

• Microprocessor-controlled operation with real-time digital display of ultrasonic duration (1–480 min), power level (40–100% of 500 W), and heating temperature (setpoint and actual)
• High-efficiency transducer array with 40 kHz resonance frequency and optimized impedance matching for improved electroacoustic conversion efficiency
• Integrated thermal regulation system with 800 W heating element and PID-based temperature control for stable thermal profiles during extended cycles
• Comprehensive safety architecture: low-water-level cutoff, over-temperature shutdown, over-voltage and over-current protection, and dry-run prevention
• Acoustically insulated lid with ergonomic latch mechanism reduces ambient noise by ≥15 dB(A) and minimizes heat loss during heated operation
• Electrically actuated fill-and-drain system with solenoid valves and level sensors enables programmable liquid handling—reducing manual intervention and cross-contamination risk
• Single-piece 304 stainless steel tank with radiused corners and electropolished interior surface for corrosion resistance and ease of decontamination

Sample Compatibility & Compliance

The KQ-500DV accommodates a broad range of laboratory vessels and components, including volumetric flasks (up to 2 L), chromatography vials, pipette tips, surgical instruments, filter housings, and semiconductor wafers (when mounted in compatible carriers). Its 27 L tank volume supports batch processing of multiple items simultaneously while maintaining uniform energy distribution across the active cleaning zone. The unit complies with general electrical safety requirements per IEC 61010-1 and meets CE marking criteria for laboratory equipment. While not certified for sterile processing per ISO 17664 or EN 285, its consistent cavitation performance supports validated cleaning procedures under GLP and GMP frameworks when incorporated into documented SOPs. Temperature and time logging capabilities support audit-ready traceability for routine QC applications.

Software & Data Management

The KQ-500DV features embedded firmware—not PC-dependent software—with non-volatile memory that retains user-defined parameters (time, power, temperature) across power cycles. All operational events—including fault triggers (e.g., low water, overheating)—are logged with timestamps in internal memory and displayed via status icons on the LED interface. Though it lacks Ethernet or USB connectivity, the unit supports integration into facility-wide monitoring systems via optional analog voltage outputs (0–5 V) for temperature and power feedback. For regulated environments requiring electronic records, external data loggers compliant with FDA 21 CFR Part 11 may be connected to record display outputs using calibrated analog-to-digital converters. No proprietary drivers or cloud platforms are required.

Applications

• Routine cleaning of HPLC columns, GC injectors, and spectrophotometer cuvettes prior to calibration
• Removal of solder flux, machining oils, and polishing compounds from precision mechanical assemblies
• Preparation of nanoparticle suspensions via ultrasonic dispersion in aqueous and organic media
• Cell lysis and DNA/RNA extraction support in molecular biology workflows
• Degassing of mobile phases and solvents prior to filtration and analysis
• Decontamination of reusable PPE components and lab tools in biosafety Level 2 settings

FAQ

Does the KQ-500DV support continuous ultrasonic operation beyond 480 minutes?

No—the maximum programmable cycle duration is 480 minutes (8 hours). For extended treatments, users must initiate sequential cycles manually or integrate external timers.

Is the 500 W ultrasonic output distributed across multiple transducers?

Yes—the system employs an array of transducers mounted uniformly along the tank base, each rated at 50 W nominal output, collectively delivering 500 W at 40 kHz with matched phase alignment.

Can the unit operate without heating enabled?

Yes—temperature control is fully independent of ultrasonic activation; users may run cold ultrasonic cycles or heated static soak modes without sonication.

What maintenance is required for long-term reliability?

Routine tasks include periodic descaling of the tank interior using dilute citric acid solution, inspection of the lid gasket for compression integrity, and verification of drain valve seal function every 6 months under daily use.

Is the electric fill/drain system compatible with deionized water delivery lines?

Yes—provided inlet water pressure remains within 0.1–0.4 MPa and conductivity does not exceed 5 µS/cm, the solenoid valves and level sensors maintain reliable operation with DI water.
