Shumei KQ-2000VDE Dual-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-2000VDE Dual-Frequency Digital Ultrasonic Cleaner is an industrial-grade, general-purpose cleaning system engineered for laboratories, R&D centers, and quality control facilities requiring high-reproducibility removal of particulate contaminants, organic residues, and micro-scale debris from precision components. It operates on the principle of acoustic cavitation generated by piezoelectric transducers bonded to the tank bottom and side walls. The dual-frequency capability—45 kHz and 80 kHz—enables selective optimization of cleaning intensity and penetration depth: lower frequency delivers higher cavitation energy suitable for robust substrates and heavy soiling, while higher frequency provides finer, more uniform cavitation ideal for delicate surfaces, microfluidic devices, optical lenses, and semiconductor wafers. With a 160 L stainless steel tank constructed entirely from AISI 304 grade material, the unit supports batch processing of large or multiple sample loads under controlled thermal and temporal conditions.

Key Features

• Dual-frequency ultrasonic generation (45 kHz / 80 kHz) with programmable frequency switching interval (0–999 s), allowing dynamic adaptation to diverse substrate geometries and soil types.
• 2000 W total ultrasonic power output, continuously adjustable from 40% to 100% in 1% increments via microprocessor-controlled amplitude modulation—ensuring consistent energy delivery across variable load conditions.
• Integrated 9000 W heating system with PID temperature regulation; precise setpoint control from ambient temperature up to 80 °C, with real-time digital display of both setpoint and actual bath temperature.
• Full digital operation via embedded single-chip microcontroller (SCM); LCD interface displays and stores user-defined parameters including ultrasonic duration (1–480 min), power level, frequency mode, switch timing, and temperature profile.
• Comprehensive safety architecture: automatic shutdown triggered by low liquid level, over-temperature, over-voltage, over-current, or dry-tank conditions—compliant with IEC 61000-4 electromagnetic compatibility standards and Class I electrical safety requirements.
• Sound-dampening lid with gas spring assist reduces operational noise to ≤65 dB(A) at 1 m distance; electrically actuated fill/drain system enables hands-free fluid management and integration into semi-automated workflows.

Sample Compatibility & Compliance

The KQ-2000VDE accommodates a broad range of sample types—including metal parts, glassware, ceramic filters, printed circuit boards (PCBs), surgical instruments, and analytical components—without risk of surface pitting or etching when operated within recommended frequency and power envelopes. Its 304 stainless steel tank meets ASTM A240 specifications for corrosion resistance in aqueous alkaline and neutral cleaning solutions. The unit is designed to support GLP-compliant documentation protocols: all parameter changes are timestamped and stored in non-volatile memory, enabling audit-ready traceability for regulated environments. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its programmable logic and data logging functionality provide a foundation for validation under GMP or ISO 17025 quality systems.

Software & Data Management

The KQ-2000VDE features a self-contained firmware platform with no external PC dependency. All operational parameters—including start time, frequency selection, power level, temperature ramp rate, dwell time, and fault logs—are retained in EEPROM with battery-backed memory retention exceeding 10 years. The LCD interface supports multi-language menu navigation (English default) and permits recall of up to 10 preconfigured cleaning programs. Optional RS-485 serial interface (available upon request) allows integration with laboratory information management systems (LIMS) or centralized process controllers for remote monitoring and event-triggered data export in CSV format. No proprietary software installation is required; configuration remains accessible via front-panel keypad only.

Applications

• Pre-analytical sample preparation: cleaning HPLC vials, GC injectors, syringe filters, and chromatography columns prior to calibration or use.
• Medical device reprocessing: removal of biofilm, blood residue, and proteinaceous matter from endoscopes, biopsy forceps, and laparoscopic tools—validated per ISO 15883 guidelines.
• Electronics manufacturing: post-solder flux removal from SMT assemblies and conformal coating inspection substrates.
• Materials science: degassing of nanoparticle suspensions, dispersion homogenization of colloidal precursors, and surface activation of polymer films prior to metallization.
• Optics and photonics: contamination-free cleaning of laser optics, fiber connectors, and interferometric components where sub-micron particle retention must be minimized.

FAQ

Can the KQ-2000VDE operate continuously for extended durations?

Yes—the system supports uninterrupted operation for up to 480 minutes per cycle, with thermal overload protection ensuring stable performance during prolonged heating and sonication sequences.
Is the dual-frequency mode synchronized or alternating?

The unit operates in alternating mode: users define the dwell time (0–999 s) for each frequency before automatic switching, enabling sequential coarse/fine cleaning stages.
What cleaning solutions are compatible with the tank?

Aqueous alkaline, neutral, and mild acidic solutions are supported; avoid halogenated solvents or strong oxidizers (e.g., concentrated HNO₃ or NaOCl >5%) to preserve transducer integrity and stainless steel passivation.
Does the unit include validation documentation?

Factory calibration certificates for temperature and timer accuracy are provided; IQ/OQ protocol templates can be supplied upon request to support site-specific qualification.
How is maintenance performed on the ultrasonic transducers?

Transducers are epoxy-bonded and sealed; no field replacement is intended. Annual inspection of bonding integrity and impedance verification using a handheld LCR meter is recommended for long-term reliability assurance.
