SHUMEI KQ-100DM Quiet-Operation Ultrasonic Cleaner

Overview

The SHUMEI KQ-100DM Quiet-Operation Ultrasonic Cleaner is a benchtop general-purpose cleaning system engineered for precision laboratory environments where consistent cavitation performance, thermal stability, and acoustic containment are critical. It operates on the principle of piezoelectric ultrasonic transduction at a fixed frequency of 40 kHz—optimized to generate uniform cavitation fields within aqueous or mild solvent-based cleaning media. This frequency balances penetration depth and micro-cleaning efficacy across diverse sample geometries, including glassware, metal components, optical lenses, and microfluidic devices. The unit integrates a 4 L stainless steel tank fabricated from seamless 304-grade stainless steel via deep-draw stamping—ensuring corrosion resistance, structural integrity, and compatibility with ISO 15190-compliant laboratory infrastructure. Its noise emission is rigorously limited to <60 dB(A) under full-load operation, achieved through integrated acoustic insulation, vibration-damping mounting, and a sealed sound-dampening lid—making it suitable for shared lab spaces, QA/QC suites, and GLP-regulated workflows where ambient noise control supports operator concentration and long-term auditory safety.

Key Features

• Stepless ultrasonic power adjustment (0–100%) enables precise optimization of cavitation intensity for delicate substrates (e.g., coated optics, MEMS devices) or heavily soiled instrumentation.
• Digital touch-control interface with real-time display of set temperature, elapsed time, and active power level—designed for intuitive, glove-compatible operation in controlled environments.
• Independent heating system (400 W) with PID-controlled temperature regulation (ambient to 80 °C), supporting thermally enhanced cleaning protocols per ASTM D4292 and ISO 11539.
• 24-hour programmable timer with auto-shutdown and hold functionality ensures repeatable process execution and unattended overnight operation.
• Comprehensive safety architecture includes liquid-level sensing, dual-stage overtemperature cutoff, and electronic overcurrent protection—meeting IEC 61010-1 requirements for laboratory electrical equipment.
• All-wetted surfaces constructed from electropolished 304 stainless steel—resistant to chlorinated solvents, alkaline detergents, and acidic rinse solutions used in validated cleaning SOPs.

Sample Compatibility & Compliance

The KQ-100DM accommodates standard laboratory vessels—including volumetric flasks (up to 1 L), Petri dishes, pipette tips, syringe filters, and small-scale chromatography columns—within its 300 × 150 × 100 mm tank cavity. Its open-tank design allows direct immersion of fixtures, racks, or custom jigs. The unit complies with CE marking directives (2014/30/EU EMC and 2014/35/EU LVD) and conforms to RoHS 2011/65/EU material restrictions. While not certified for sterile processing per ISO 13485, its construction and operational parameters align with cleaning validation prerequisites outlined in USP Analytical Instrument Qualification and EU GMP Annex 15 Section 5.2 for non-sterile equipment cleaning verification.

Software & Data Management

As a standalone analog-digital hybrid instrument, the KQ-100DM does not incorporate network connectivity or proprietary software. All operational parameters are configured locally via the front-panel touchscreen; no external drivers, cloud services, or firmware updates are required. However, its deterministic timer and temperature control enable full traceability when integrated into paper-based or electronic batch records. For laboratories operating under FDA 21 CFR Part 11, manual log entries—including operator ID, cycle parameters, and visual inspection outcomes—can be formally linked to each cleaning event. Optional third-party data loggers (e.g., calibrated thermocouple + timer modules) may be deployed externally to capture temperature profiles during qualification studies.

Applications

• Pre-analytical sample preparation: removal of organic residues from HPLC vials, GC autosampler trays, and ICP-MS nebulizer components.
• Quality control of medical device components: deburring, flux residue removal, and particulate clearance from stainless steel surgical instruments prior to sterilization.
• Electronics manufacturing: cleaning of PCB assemblies, solder paste stencils, and semiconductor wafer carriers using low-surface-tension aqueous formulations.
• Academic research labs: routine decontamination of centrifuge rotors, electrophoresis tanks, and cell culture accessories without compromising dimensional tolerances.
• Pharmaceutical R&D: cleaning of dissolution apparatus baskets, paddle shafts, and filter housings in accordance with USP Cleaning Validation Guidance.

FAQ

Is the KQ-100DM suitable for use with flammable solvents?
No. This unit is designed exclusively for aqueous or water-miscible, non-flammable cleaning solutions. Operation with alcohol, acetone, or hydrocarbon-based solvents poses fire and explosion hazards and voids the warranty.
Does the unit include validation documentation or IQ/OQ protocols?
The KQ-100DM ships with a Factory Acceptance Test (FAT) report and calibration certificate for temperature and timer functions. Custom IQ/OQ documentation templates compatible with GxP environments are available upon request.
Can the ultrasonic transducers be replaced in the field?
Yes. The unit employs standardized 40 kHz piezoelectric transducers mounted on the tank bottom. Replacement kits—including matched transducer arrays and coupling compound—are supplied by SHUMEI with technical installation guidance.
What maintenance is required to ensure long-term performance?
Routine maintenance includes periodic descaling of the tank interior using 5% citric acid solution, inspection of the drain valve seal integrity every 6 months, and verification of lid gasket compression force annually.
Is the stainless steel mesh basket autoclavable?
Yes. The included 304 stainless steel mesh basket and support rack are rated for repeated autoclaving at 121 °C, 15 psi for up to 30 minutes—supporting integration into sterile workflow sequences.
