Shumei KQ-400DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ-400DE Digital Ultrasonic Cleaner is a benchtop general-purpose cleaning system engineered for precision laboratory and industrial maintenance applications. It operates on the principle of ultrasonic cavitation—generating high-frequency pressure waves (40 kHz) in aqueous or solvent-based cleaning media to dislodge particulate contaminants, organic residues, and biofilms from delicate surfaces without mechanical abrasion. Designed for reproducible, non-destructive cleaning of glassware, metal parts, optical components, surgical instruments, printed circuit boards, and analytical sample preparation vessels, the KQ-400DE integrates digital process control with robust stainless-steel construction to meet routine QC, R&D, and GLP-aligned workflows.

Key Features

• Microprocessor-controlled operation with intuitive digital interface for independent adjustment of ultrasonic power (40–100% of 400 W nominal output), heating temperature (ambient to 80 °C), and cleaning duration (1–480 minutes).
• 304 stainless steel tank (330 × 300 × 150 mm internal dimensions) and housing ensure corrosion resistance, long-term structural integrity, and compatibility with common alkaline, acidic, and neutral cleaning solutions.
• Integrated safety architecture includes real-time monitoring of liquid level, tank temperature, input voltage, and current draw—with automatic shutdown triggered by low fluid level, overheating, overvoltage, overcurrent, or dry-run conditions.
• Digital LED display simultaneously shows setpoints and real-time values for temperature, elapsed time, ultrasonic power percentage, and fill-level indication—enabling full operational traceability during batch processing.
• Sound-dampening hinged lid reduces ambient noise emission and minimizes solvent evaporation during heated operation, supporting safer handling and improved energy efficiency.
• Manual inlet and drain valves allow flexible integration into lab utility infrastructure; no external plumbing required. Includes stainless steel mesh basket and support rack for optimized part suspension and acoustic coupling.

Sample Compatibility & Compliance

The KQ-400DE accommodates a wide range of substrates—including borosilicate glass, aluminum, titanium, stainless steel, ceramics, and polymer components—without surface etching or dimensional alteration under standard operating parameters. Its 15 L working volume supports cleaning of multiple items simultaneously while maintaining uniform cavitation distribution across the tank floor. The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-1 (immunity) standards. While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, its programmable parameters and audit-ready digital logging support documentation requirements for ISO/IEC 17025-accredited laboratories performing cleaning validation per ASTM F3127 or USP .

Software & Data Management

This model does not include PC connectivity or proprietary software. All operational parameters are stored and recalled via non-volatile memory within the onboard microcontroller. Each session’s settings—including power level, temperature setpoint, timer value, and safety event logs (e.g., low-level alerts)—are retained across power cycles. For laboratories requiring electronic records, manual entry into LIMS or ELN systems is supported through documented SOPs referencing displayed values and timestamped process logs. The absence of network interfaces ensures electromagnetic isolation critical in sensitive instrumentation environments.

Applications

• Routine decontamination of volumetric flasks, pipettes, crucibles, and HPLC vials prior to calibration or analysis.
• Removal of cutting oils, polishing compounds, and flux residues from machined metal components in quality assurance labs.
• Preparation of electron microscopy specimens and semiconductor wafers requiring particle-free surfaces.
• Cleaning of reusable surgical and dental instruments in veterinary or research animal facilities—when used with validated disinfectant-compatible chemistries.
• Supporting ASTM D2240 (durometer calibration) and ISO 9227 (corrosion test specimen prep) sample conditioning protocols.

FAQ

Is the KQ-400DE suitable for cleaning delicate optics or MEMS devices?

Yes—when operated at reduced power (40–60%) and with degassed, low-surface-tension solvents, it achieves gentle yet effective contaminant removal without damaging micromachined features or anti-reflective coatings.
Does it support continuous operation beyond 480 minutes?

No—the maximum timer setting is 480 minutes; extended cleaning requires manual reset. For unattended overnight cycles, users must implement external timing relays or integrate with facility automation systems.
Can the unit be used with flammable solvents?

Not recommended. The heater and transducer design are rated for aqueous and high-flashpoint solvents only. Use in explosion-proof enclosures or with intrinsically safe controllers is required for volatile organics.
What maintenance is required for long-term reliability?

Annual inspection of transducer bonding integrity, periodic descaling of the tank interior using citric acid solution, and verification of temperature sensor calibration against a NIST-traceable reference thermometer.
Is technical documentation available in English?

Yes—full bilingual (English/Chinese) user manual, electrical schematics, and CE-conformity declarations are supplied with each unit and available upon request from Shumei’s technical support team.
