Supmile KQ-1500VDE Floor-Standing Triple-Frequency Digital Ultrasonic Cleaner

Overview

The Supmile KQ-1500VDE is a floor-standing, triple-frequency digital ultrasonic cleaner engineered for high-reproducibility cleaning across diverse sample types and contamination profiles. Unlike single-frequency systems constrained by fixed cavitation dynamics, this instrument leverages programmable alternation among three discrete ultrasonic frequencies—45 kHz, 80 kHz, and 100 kHz—to optimize acoustic energy delivery across varying particle sizes, substrate geometries, and contaminant adhesion mechanisms. At 45 kHz, the system generates larger, higher-energy cavitation bubbles suited for macro-particulate removal and robust surface cleaning; at 80 kHz, it delivers balanced energy distribution ideal for general-purpose laboratory components such as glassware, metal fixtures, and ceramic substrates; and at 100 kHz, it produces finer, more uniformly distributed cavitation events essential for delicate instrumentation, microfluidic devices, and precision optics where surface integrity must be preserved. The unit’s 112-liter stainless steel tank (700 × 400 × 400 mm internal dimensions) supports batch processing of large or multiple items—including chromatography columns, reactor vessels, filtration assemblies, and surgical instruments—while its VDE-series architecture ensures structural rigidity, thermal insulation, and acoustic attenuation.

Key Features

• Floor-standing design with reinforced load-bearing chassis for stable operation in high-throughput lab environments
• Triple-frequency digital generator with automatic frequency-switching logic—user-selectable dwell times per frequency (1–999 s) enable process optimization for multi-stage cleaning protocols
• Full digital control interface with real-time display of operating parameters: frequency mode, power output (%), bath temperature (°C), elapsed time, and remaining cycle duration
• Precise temperature regulation via PID-controlled heating (10–80 °C range) with ±1 °C stability, critical for temperature-sensitive solvents and enzymatic decontamination steps
• Ultrasonic power adjustable from 40% to 100% of nominal 1500 W output—enabling fine-tuned energy delivery to prevent sample erosion or solvent degradation
• Integrated sound-dampening lid constructed from multi-layer stainless steel and acoustic insulation material, reducing ambient noise to ≤65 dB(A) at 1 m distance
• VDE-grade 304 stainless steel construction throughout: tank, basket, housing, and lid—resistant to corrosion from aqueous, alcoholic, and mild alkaline cleaning solutions

Sample Compatibility & Compliance

The KQ-1500VDE accommodates a broad spectrum of sample formats and materials without compromising cleaning efficacy or equipment longevity. Compatible substrates include borosilicate glass, stainless steel, titanium alloys, anodized aluminum, silicone elastomers, and polymer-based microplates—provided they are not ultrasonically fragile (e.g., certain thin-film sensors or MEMS devices). Its open-bath configuration allows immersion of irregularly shaped objects up to 700 mm × 400 mm × 400 mm. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device supports GLP/GMP-aligned workflows through auditable parameter logging (when paired with external data acquisition systems), repeatable protocol execution, and traceable temperature/power calibration points. It complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge and RF fields), ensuring reliable operation in shared laboratory infrastructure.

Software & Data Management

The KQ-1500VDE operates via an embedded microcontroller with non-volatile memory capable of storing up to 10 user-defined cleaning programs—including frequency sequence, power setpoints, temperature ramp profiles, and timer durations. Each program retains its own timestamped execution history (last 50 cycles), accessible via front-panel navigation. Though the unit lacks native Ethernet or USB host connectivity, optional RS-485 serial interface modules (sold separately) enable integration into centralized lab automation platforms for remote start/stop commands and status polling. All parameter changes are logged with date/time stamps, supporting basic audit trail requirements for quality-controlled environments. For full 21 CFR Part 11 compliance—including electronic signatures and secure user access—external validation and third-party software integration (e.g., LabArchives or custom SCADA) are recommended.

Applications

• Pre-analytical sample preparation: removal of residual proteins, lipids, and particulates from HPLC vials, autosampler needles, and syringe filters
• Medical device reprocessing: cleaning of reusable endoscopic components, biopsy forceps, and laparoscopic instruments prior to sterilization
• Materials science: degassing of ceramic slurries, dispersion of nanomaterials in suspension media, and removal of sintering aids from green-state compacts
• Electronics manufacturing: flux residue removal from PCB assemblies and ultrasonic-assisted wire bonding surface activation
• Pharmaceutical QC labs: cleaning of dissolution apparatus baskets, tablet friability testers, and analytical balance pans per USP & EP guidelines
• Academic research: extraction of metabolites from plant tissues, cell lysis for proteomics, and sonication-assisted nanoparticle synthesis

FAQ

What cleaning solutions are compatible with the KQ-1500VDE?

Aqueous detergents, ethanol/water mixtures, isopropanol, and mild alkaline solutions (pH 9–11) are routinely used. Avoid concentrated acids, halogenated solvents (e.g., chloroform), and highly viscous fluids unless validated for compatibility with 304 stainless steel and ultrasonic transducer integrity.
Can the unit operate continuously for extended periods?

Yes—continuous operation up to 480 minutes per cycle is supported. For unattended overnight runs, ensure proper ventilation, coolant circulation (if using heated baths >60 °C), and solvent level monitoring to prevent dry-run damage.
Is the 100 kHz frequency suitable for cleaning optical lenses?

Yes, when combined with low-power settings (≤50% output) and non-abrasive, low-surface-tension solvents (e.g., 2-propanol), 100 kHz provides gentle yet effective removal of fingerprint residues and sub-micron dust without micro-scratching.
Does the manual drain/inlet support automated fill-level control?

No—the KQ-1500VDE uses manual valve actuation for fill and drain. For automated fluid handling, consider the AS-series variants (e.g., KQ-AS1500VDE), which feature electrically actuated solenoid valves and adjustable liquid-level sensors.
How often should the ultrasonic transducers be calibrated?

Transducer performance should be verified annually using a calibrated hydrophone or cavitation intensity probe per ASTM E1415-19. Visual inspection for delamination or pitting on the tank bottom is recommended before each high-intensity use cycle.
