Supmile KQ-500VDV Dual-Frequency Ultrasonic Cleaner

Overview

The Supmile KQ-500VDV is a benchtop dual-frequency ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, analytical instrumentation parts, and small-volume production tooling. It operates on the principle of acoustic cavitation—generating high-intensity microbubbles in liquid media via piezoelectric transducers mounted to the tank bottom. The dual-frequency capability (45 kHz and 80 kHz) enables selective optimization: lower frequency delivers higher cavitation intensity for robust particulate removal from machined surfaces, while higher frequency provides finer, gentler agitation ideal for microstructures, MEMS devices, or coated substrates where surface integrity must be preserved. With a 27-liter stainless-steel tank (500 × 300 × 180 mm internal dimensions), this unit supports batch processing of multiple sample carriers, glassware, filtration assemblies, and semiconductor wafers without compromising uniform energy distribution.

Key Features

• Dual-frequency operation (45 kHz / 80 kHz) with programmable frequency switching—enabling process-specific cleaning profiles for diverse material classes and contamination types.
• Digitally controlled ultrasonic power output (500 W total, adjustable from 40% to 100% in 1% increments) ensures reproducible energy delivery across repeated cycles.
• Precise digital temperature regulation (10–80 °C, ±1 °C accuracy) using integrated Pt100 sensor feedback and PID-controlled heating element (1000 W).
• Programmable timer (1–480 minutes) with auto-shutdown and memory retention for last-used parameters—including power level, frequency selection, temperature setpoint, and duration.
• Robust 304 stainless-steel tank construction (deep-drawn, argon-welded seams) resistant to corrosion from aqueous, alkaline, and mild solvent-based cleaning solutions.
• Integrated safety protections: low-water level cutoff, overtemperature shutdown, overcurrent detection, and real-time display of actual vs. set temperature and power load.
• Electrically actuated drain valve with programmable water-level sensing (adjustable fill threshold: 1–140 mm), enabling automated solution exchange and reduced operator intervention.
• Fold-down acoustic lid with silicone gasket minimizes airborne noise (<65 dB(A) at 1 m) and prevents solvent evaporation during heated operation.

Sample Compatibility & Compliance

The KQ-500VDV accommodates a broad range of sample geometries and materials, including but not limited to: glass vials, quartz cuvettes, HPLC columns, sintered metal filters, ceramic crucibles, printed circuit boards (PCBs), dental instruments, and precision-machined calibration standards. Its non-contact cleaning mechanism avoids mechanical abrasion, making it suitable for fragile or coated components. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements). While not certified for medical device reprocessing per ISO 15883 or EN 285, its programmable parameters and audit-ready digital logging support GLP-aligned documentation when integrated into validated lab workflows. For regulated environments, optional RS232/USB data export allows timestamped parameter records compatible with 21 CFR Part 11-compliant electronic signature systems.

Software & Data Management

Control logic is implemented via an embedded industrial-grade microcontroller with firmware supporting full parameter recall and cycle replication. All operational settings—including frequency mode, power percentage, target temperature, dwell time, and drain activation sequence—are stored in non-volatile memory and persist through power cycling. Real-time status indicators display actual tank temperature, elapsed time, active frequency, and power draw. Optional PC connectivity (via included USB-to-serial adapter) enables remote monitoring, batch logging, and export of CSV-formatted operation logs—including start/stop timestamps, deviations from setpoints, and fault event codes. These logs facilitate traceability for quality audits and process validation in ISO/IEC 17025-accredited laboratories.

Applications

• Pre-analytical sample preparation: removal of organic residues from GC vials, autosampler needles, and syringe filters prior to chromatographic analysis.
• Maintenance of metrology equipment: cleaning of interferometer optics, laser alignment targets, and coordinate measuring machine (CMM) probe tips.
• Electronics manufacturing: post-solder flux residue removal from SMT stencils, PCBs, and wafer carriers without damaging fine-pitch interconnects.
• Materials science labs: degassing of nanoparticle suspensions, dispersion homogenization, and surface decontamination of catalyst supports prior to BET analysis.
• Pharmaceutical R&D: cleaning of dissolution apparatus baskets, sinker weights, and filter housings in accordance with USP recommendations for equipment hygiene.
• Academic research: routine maintenance of TEM grids, AFM cantilevers, and microfluidic chips requiring particle-free surfaces.

FAQ

What is the recommended cleaning solution for use with the KQ-500VDV?
Aqueous alkaline or neutral pH detergents are preferred for general labware cleaning. For heavy organic soils, ethanol- or isopropanol-based solutions may be used—but only below their flash point and with adequate ventilation. Avoid halogenated solvents unless explicitly approved by local safety regulations and tank compatibility testing.
Can the unit operate continuously for extended periods?
Yes—the system includes thermal management for sustained operation up to 480 minutes per cycle. However, for optimal transducer longevity and consistent cavitation performance, intermittent duty cycles (e.g., 10 min on / 2 min off) are recommended when operating above 80% power for >2 hours.
Is the frequency switching automatic or manually selected?
Frequency selection is manually configured via front-panel interface. Users may choose either 45 kHz, 80 kHz, or alternating mode (with user-defined dwell time per frequency, 1–999 seconds per segment).
Does the unit support external trigger input for synchronized operation?
No native digital I/O is provided; however, the electric drain valve can be interfaced with external PLCs via its 24 VDC control signal terminals (documentation available upon request).
How is calibration verification performed?
While no built-in calibration certificate is supplied, users may verify temperature accuracy using NIST-traceable thermometers and assess cavitation uniformity via aluminum foil erosion test (ASTM D2603-18 Annex A1) or hydrophone mapping per IEC 61847.
