Shumei KQ-AS1000GDE Digital Temperature-Controlled Ultrasonic Cleaner

Overview

The Shumei KQ-AS1000GDE is a high-capacity, digitally controlled ultrasonic cleaning system engineered for precision laboratory, quality control, and industrial maintenance applications requiring reproducible, non-destructive removal of particulate, organic, and thin-film contaminants from complex geometries. Operating on the principle of cavitation—where high-frequency acoustic energy (40 kHz) induces rapid formation and collapse of microbubbles in aqueous or compatible solvent media—the unit delivers uniform energy distribution across its 72-liter stainless steel tank (600 × 300 × 400 mm internal volume). Its integrated thermostatic control (0–80 °C, ±2 °C accuracy), programmable timer (1–480 minutes), and adjustable ultrasonic output (40–100% of 1000 W nominal power) enable method-driven optimization for diverse substrates including optical components, surgical instruments, semiconductor wafers, printed circuit boards, and analytical sample holders. Constructed entirely from ASTM A240 304 stainless steel, the system ensures long-term corrosion resistance and compatibility with standard cleaning chemistries such as alkaline detergents, enzymatic solutions, and low-concentration solvents.

Key Features

• Digital microprocessor-based control interface with real-time display of temperature (setpoint and actual), ultrasonic power level, elapsed time, and liquid level status
• Electrically actuated sound-dampening lid with safety interlock to suppress airborne noise and prevent operator exposure to cavitation-induced aerosols
• Automated fluid handling: electrically controlled inlet and drain valves for repeatable fill/drain cycles—reducing manual intervention and cross-contamination risk
• Multi-layer protection architecture: continuous monitoring for low liquid level, overtemperature, overvoltage, overcurrent, and dry-run conditions, with immediate shutdown and visual alarm indication
• Integrated filtration module with replaceable cartridge to maintain bath purity during extended operation or multi-batch processing
• High-efficiency transducer array optimized for 40 kHz resonance, delivering stable acoustic output with minimal harmonic distortion and thermal drift
• Configurable power supply input (AC 220 V / 50 Hz or AC 380 V / 50 Hz) for flexible integration into varied facility electrical infrastructures

Sample Compatibility & Compliance

The KQ-AS1000GDE accommodates a broad range of sample types—including metal, glass, ceramic, and certain thermally stable polymers—without compromising structural integrity or surface finish when operated within validated parameter windows. Its design supports routine cleaning validation protocols aligned with ISO 13485 (for medical device reprocessing), ASTM D2603 (ultrasonic cleaning performance evaluation), and USP (Cleaning Validation of Laboratory Equipment). The stainless steel tank and fluid path meet FDA-recommended material specifications for non-porous, cleanable surfaces. While not certified to GLP or GMP out-of-the-box, the system’s digital logging capability (via optional RS232/USB data export) facilitates audit-ready documentation for regulated environments where traceability of cleaning parameters (time, temperature, power) is required per 21 CFR Part 11 Annex 11 principles.

Software & Data Management

The embedded control firmware supports persistent memory for up to 10 user-defined cleaning programs, each storing temperature setpoint, power level, duration, and ramp profiles. All operational events—including start/stop timestamps, fault triggers, and parameter modifications—are timestamped and stored in non-volatile memory. Optional serial (RS232) or USB connectivity enables export of CSV-formatted logs for integration into laboratory information management systems (LIMS) or electronic batch records. No proprietary software installation is required; raw data files are readable in standard spreadsheet applications. Firmware updates are performed via secure USB drive, ensuring version control and compliance with internal IT security policies.

Applications

• Precision cleaning of HPLC/GC injection syringes, columns, and sample vials prior to chromatographic analysis
• Decontamination of reusable surgical and dental instruments in central sterile supply departments (CSSD)
• Removal of photoresist residues and etch byproducts from silicon wafers and MEMS devices
• Preparation of electron microscopy grids and TEM specimens requiring particle-free surfaces
• Restoration of vintage optical lenses and metrology standards without abrasive contact
• Batch cleaning of calibration weights, pipette tips, and volumetric glassware in metrology labs

FAQ

What is the maximum recommended operating temperature for aqueous cleaning solutions?
The system is rated for continuous operation at temperatures up to 80 °C; however, sustained use above 60 °C with water-based solutions may accelerate evaporation and require more frequent bath replenishment.
Can the unit be used with flammable solvents?
No. The KQ-AS1000GDE is not explosion-proof and is designed exclusively for aqueous or non-flammable, low-volatility cleaning agents compliant with IEC 61000-6-3 EMC standards.
Is the filtration system compatible with inline sterilization?
The standard filter housing is not rated for autoclaving or SIP (steam-in-place); replacement cartridges are disposable and intended for single-batch or multi-batch reuse under validated cleaning intervals.
How is temperature uniformity maintained across the tank volume?
A distributed heating element array combined with passive convection and optional ultrasonic agitation ensures ±2 °C stability at sensor location; verification via calibrated PT100 probe at multiple tank positions is recommended for critical applications.
Does the system support remote monitoring or network integration?
Native Ethernet or Wi-Fi connectivity is not included; however, third-party PLC gateways or serial-to-Ethernet converters can be deployed to enable SCADA-level supervision in facility-wide automation frameworks.
