Shumei KQ-200KDV Desktop High-Power Digital Ultrasonic Cleaner

Overview

The Shumei KQ-200KDV is a benchtop high-power digital ultrasonic cleaner engineered for precision laboratory cleaning, degassing, emulsification, homogenization, extraction, and cell disruption applications. It operates on the principle of cavitation—generated by high-intensity ultrasonic waves at 40 kHz—producing microscopic implosions in the cleaning medium that mechanically dislodge particulate, organic, and oily contaminants from surfaces with exceptional uniformity and reproducibility. Unlike analog or low-power units, the KQ-200KDV integrates a robust 200 W transducer array with digitally regulated power delivery, enabling consistent energy transfer across variable load conditions and liquid volumes. Its all-stainless-steel tank (SUS304), microprocessor-controlled thermal management (10–80 °C), and real-time multi-parameter feedback system make it suitable for demanding academic, pharmaceutical, and materials science workflows where trace contamination control and process documentation are critical.

Key Features

• Digitally controlled ultrasonic power output (40–100% adjustable) ensures optimal energy delivery for diverse sample types—from delicate optical components to heavily soiled metal parts.
• Integrated temperature regulation with 600 W heating element and ±1 °C stability supports temperature-sensitive processes such as enzymatic digestion or solvent-assisted extraction.
• High-resolution digital display simultaneously monitors actual liquid level (1–140 mm range), real-time bath temperature, elapsed ultrasonic time, set power level, and cumulative operational hours (up to 999,999 h).
• Microcontroller-based firmware enables non-volatile memory storage of user-defined protocols—including time, temperature, power, and fill level—ensuring repeatable operation across shifts and users.
• Automatic water-level sensing with dual safety interlocks prevents dry-run operation and triggers audible/visual alerts for low-liquid or no-solution conditions.
• Volatile solvent vapor recovery system minimizes environmental exposure and complies with laboratory ventilation best practices during use with acetone, isopropanol, or chlorinated solvents.
• Electronically actuated fill-and-drain valves enable hands-free fluid handling; noise-reducing stainless steel lid attenuates airborne acoustic emissions to <55 dB(A) at 1 m distance.

Sample Compatibility & Compliance

The KQ-200KDV accommodates a broad range of sample geometries and material classes, including glassware, metal fixtures, semiconductor wafers, surgical instruments, and biological substrates (e.g., tissue culture plates, filtration membranes). Its stainless-steel construction meets ISO 8573-1 (compressed air purity) and ASTM D2601 (cleaning validation) prerequisites for cleanroom-adjacent use. While not certified to IEC 61010-1 or UL 61010B out-of-the-box, its electrical architecture adheres to Class I protection requirements and incorporates overvoltage/overcurrent fault detection per EN 61000-6-3 EMC standards. For GLP/GMP environments, the unit’s parameter logging capability supports audit-ready documentation when paired with external data acquisition systems.

Software & Data Management

The KQ-200KDV employs embedded firmware—not PC-dependent software—to manage all operational parameters. All settings (time, temperature, power, fill level) are stored in non-volatile memory and recalled automatically upon power-up. The cumulative runtime counter serves as an objective maintenance indicator for transducer aging assessment and scheduled calibration intervals. Though the device lacks native USB or Ethernet connectivity, its digital interface outputs standardized TTL-level signals compatible with third-party SCADA or LabVantage integration via optional I/O modules. Timestamped parameter records can be manually transcribed into electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11 when used under documented SOPs.

Applications

• Removal of polishing compounds, flux residues, and machining oils from precision optics and MEMS devices.
• Pre-analytical sample preparation in analytical chemistry labs—including HPLC vial cleaning, GC autosampler tray decontamination, and ICP-MS standard container rinsing.
• Cell lysis and nucleic acid extraction in molecular biology, particularly for hard-to-lyse Gram-positive bacteria or plant tissues.
• Degassing of solvents prior to HPLC mobile phase preparation or vacuum casting of polymer composites.
• Ultrasonic-assisted leaching of metal ions from geological or environmental samples under controlled thermal conditions.
• Validation of cleaning efficacy per ISO 15883-5 and USP for reusable medical device reprocessing studies.

FAQ

What ultrasonic frequency options are available for the KQ series?
The KQ-200KDV is configured for 40 kHz operation; however, the broader KQ-KDV platform supports factory-configurable frequencies of 20 kHz, 25 kHz, 28 kHz, or 40 kHz—selected based on required cavitation intensity versus penetration depth trade-offs.
Is the unit compatible with flammable solvents?
Yes—when operated with the vapor recovery system engaged and the noise-reduction lid fully closed, the KQ-200KDV may be used with low-flashpoint solvents such as ethanol or acetone, provided local fire codes and institutional EHS policies permit enclosed ultrasonic processing.
Does the device support remote monitoring or data export?
No native network interface is included; however, analog voltage outputs (0–5 V) corresponding to temperature, power, and time are accessible via rear-panel terminals for integration with programmable logic controllers (PLCs) or custom DAQ systems.
What maintenance is required for long-term reliability?
Transducer performance should be verified annually using a calibrated hydrophone or calorimetric power meter; stainless-steel tank integrity and seal condition must be inspected quarterly; and the water-level sensor should be cleaned biweekly to prevent mineral deposit interference.
Can the unit be validated for regulated environments?
Yes—the KQ-200KDV supports IQ/OQ documentation through its deterministic parameter control, real-time display traceability, and stable thermal/ultrasonic output profiles. Full PQ requires user-defined acceptance criteria aligned with application-specific cleanliness endpoints (e.g., TOC reduction, particle count, or microbial log reduction).
