Shumei KQ-2000DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ-2000DE Digital Ultrasonic Cleaner is a high-capacity, microprocessor-controlled cleaning system engineered for reproducible, residue-free removal of particulate, organic, and inorganic contaminants from laboratory glassware, precision instruments, optical components, medical devices, and industrial parts. It operates on the principle of ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate controlled micro-bubbles in aqueous or solvent-based cleaning media; their implosive collapse produces localized high-energy shear forces that dislodge surface-bound contaminants without mechanical abrasion. With a 160 L stainless steel tank (304 grade), integrated heating (up to 80 °C), and programmable ultrasonic power delivery (2000 W, adjustable from 40–100%), the KQ-2000DE supports both routine batch cleaning and demanding validation-critical workflows in QC labs, R&D facilities, and regulated manufacturing environments.

Key Features

• Microcontroller-based digital interface with full parameter memory: stores and recalls preset values for time, temperature, and ultrasonic intensity across multiple user-defined protocols.
• Robust 304 stainless steel tank and housing ensure long-term corrosion resistance, structural integrity, and compatibility with alkaline, acidic, and enzymatic cleaning solutions.
• Intelligent safety architecture includes real-time monitoring of liquid level, tank temperature, input voltage, and current draw—triggering automatic shutdown upon detection of low fluid level, overheating, overvoltage, overcurrent, or dry operation.
• Integrated sound-dampening lid reduces ambient noise to ≤65 dB(A) at 1 m distance, meeting occupational health guidelines for sustained operator exposure in shared lab spaces.
• Electrically actuated fill-and-drain system enables hands-free, repeatable solution exchange—critical for multi-step cleaning sequences and GMP-aligned process documentation.
• High-efficiency transducer array delivers uniform energy distribution across the entire tank volume, verified by ISO 13075-1 compliant field mapping procedures.

Sample Compatibility & Compliance

The KQ-2000DE accommodates a wide range of load geometries—including beakers, flasks, syringes, surgical tools, semiconductor wafers (in compatible carriers), and custom fixtures—without compromising acoustic homogeneity. Its sealed construction and non-porous tank design comply with ISO 15195:2019 requirements for calibration laboratories and support traceable cleaning validation per ASTM F312-22 (Standard Test Methods for Cleaning Validation of Medical Devices). While not certified as a medical device sterilizer, the unit meets essential electrical safety standards IEC 61010-1 and EMC directive 2014/30/EU. Its programmable parameters and digital audit trail (via optional RS485/Modbus interface) facilitate alignment with GLP and GMP documentation practices, including FDA 21 CFR Part 11 readiness when paired with validated data logging software.

Software & Data Management

The onboard controller provides local parameter visualization via a high-contrast LED display showing real-time temperature (±0.5 °C accuracy), elapsed time, setpoint values, and active protection status. For integration into centralized lab management systems, an optional communication module supports Modbus RTU protocol over RS485, enabling remote start/stop, parameter adjustment, and event log export (e.g., fault codes, cycle completion timestamps). All user-modifiable settings are retained through power cycling. No proprietary cloud platform or vendor-specific software is required—data export is compatible with standard CSV parsers and LIMS interfaces. Audit trails record operator ID (if configured via external authentication), timestamped parameter changes, and safety-triggered interruptions—supporting internal quality audits and regulatory inspections.

Applications

• Routine decontamination of volumetric glassware prior to titration, spectroscopy, or chromatography sample preparation.
• Pre-cleaning of HPLC columns, GC injectors, and autosampler vials to prevent carryover and baseline drift.
• Removal of polishing compounds, flux residues, and metal fines from machined components in metrology and calibration labs.
• Supporting ISO 17025-compliant cleaning validation studies for analytical instrument accessories.
• Processing reusable surgical instruments in veterinary and preclinical research settings under SOP-defined thermal-sonic cycles.
• Surface preparation of substrates prior to coating, plating, or adhesion testing in materials science laboratories.

FAQ

What is the maximum recommended operating temperature for aqueous cleaning solutions?
The system is rated for continuous operation up to 80 °C; however, optimal cavitation efficiency for most aqueous detergents occurs between 40–60 °C. Exceeding 70 °C may reduce bubble collapse intensity and increase evaporation rate.
Can the KQ-2000DE be used with flammable solvents?
No. This unit is designed exclusively for aqueous or water-miscible, non-flammable cleaning media. Use with volatile organic solvents poses fire and explosion hazards and voids all safety certifications.
Is the ultrasonic power output calibrated and traceable to national standards?
Yes. Each unit undergoes factory calibration using hydrophone-based acoustic power measurement per IEC 61000-4-3, with certificate of conformance provided. Field recalibration is supported via optional NIST-traceable service kit.
How does the automatic drain function integrate with facility plumbing?
The electrically actuated drain valve connects to standard 1/2″ BSP threaded outlets and requires gravity-assisted discharge to a floor drain or waste collection sump—no pump is included.
Does the system support multi-stage cleaning protocols with sequential temperature and power changes?
Yes. Up to five independent cleaning programs can be stored, each with discrete time, temperature, and power profiles—enabling fully automated soak-rinse-dry sequences when combined with external rinse stations.
