Shumei KQ-100KDE Benchtop High-Power Digital Ultrasonic Cleaner

Overview

The Shumei KQ-100KDE is a benchtop high-power digital ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, cell disruption, and solvent-based extraction in academic, R&D, and quality control laboratories. It operates on the principle of cavitation—generated by high-intensity acoustic pressure waves at a fixed frequency of 40 kHz—producing transient microbubbles that collapse near solid surfaces, delivering localized mechanical energy sufficient to dislodge particulate contaminants, organic residues, and biofilms without mechanical abrasion. Unlike analog or low-power units, the KQ-100KDE integrates a robust piezoelectric transducer array capable of sustained 100 W nominal output, with digitally regulated power delivery across a 40–99% range to accommodate diverse sample matrices—from delicate optical components to hardened metal substrates. Its sealed stainless steel tank (304 grade), precision temperature control (10–80 °C), and programmable timer ensure repeatability critical for method validation under GLP-compliant workflows.

Key Features

• Digital microcontroller-based operation (KDV series firmware) enabling full parameter recall and reproducible program execution
• Real-time dual-display interface showing both setpoints and actual values for ultrasonic duration, power level, bath temperature, and liquid level status
• Integrated safety architecture: automatic shutdown triggered by low liquid level, over-temperature, over-current, or voltage fluctuation
• High-fidelity temperature regulation via PID-controlled 200 W immersion heater with ±1 °C stability across the 10–80 °C range
• Acoustically damped motorized lid to reduce ambient noise and minimize solvent evaporation during extended cycles
• Cumulative operating hour counter (up to 999,999 h) supporting preventive maintenance scheduling and ISO 17025 traceability requirements
• Stainless steel tank formed by deep-drawn stamping—no weld seams—to eliminate crevices where residue may accumulate
• Modular PP mesh basket designed for uniform acoustic field distribution and compatibility with aqueous and mild organic solvents

Sample Compatibility & Compliance

The KQ-100KDE supports a broad spectrum of sample types including glassware, metallic tools, semiconductor wafers, ceramic filters, and biological substrates such as tissue culture plates and microfluidic chips. Its 2 L capacity and compact inner dimensions (150 × 140 × 100 mm) are optimized for batch processing of small-to-medium laboratory vessels. The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its electrical design meets UL/CSA Class II insulation standards. While not certified for sterile processing per ISO 13485, it is routinely deployed in pre-sterilization cleaning steps aligned with ISO 15883-1 and ASTM F3127 protocols for reusable medical device reprocessing validation. All operational parameters—including time, temperature, and power—are logged internally and exportable for audit trails required under FDA 21 CFR Part 11 (when paired with compliant data capture software).

Software & Data Management

The KQ-100KDE embeds non-volatile memory to retain user-defined programs, calibration offsets, and cumulative runtime data across power cycles. Though it lacks Ethernet or USB host connectivity, its real-time display logs timestamped events—including fault codes, thermal excursions, and power interruptions—for manual documentation. When integrated into networked lab environments, third-party SCADA or LIMS systems can interface via optional RS-232 or 4–20 mA analog outputs (available on OEM-configured variants). All parameter settings adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), facilitating compliance with GxP documentation practices.

Applications

• Precision cleaning of HPLC columns, GC injectors, and spectrophotometer cuvettes prior to calibration
• Removal of photoresist residues from silicon wafers in microfabrication labs
• Cell lysis and nucleic acid extraction in molecular biology workflows
• Degassing of solvents prior to chromatographic analysis or vacuum filtration
• Dispersing nanoparticles in suspension for TEM grid preparation
• Debonding adhesive residues from optical lenses and sensor housings
• Pre-cleaning of ASTM E2912 test coupons for corrosion inhibitor evaluation

FAQ

Is the KQ-100KDE suitable for use with flammable solvents?
No. This model is rated for aqueous and water-miscible solutions only. Flammable solvent use requires explosion-proof certification (e.g., UL 1203) and is not supported.
Can the ultrasonic frequency be changed after purchase?
No. Frequency is hardware-determined at manufacture; 40 kHz is fixed for this variant. Other KQ-series models offer 20/25/28 kHz options.
Does the unit support external temperature probes?
Not natively. Bath temperature sensing is internal only, using a calibrated PT100 sensor embedded in the tank wall.
What maintenance is required for long-term reliability?
Monthly inspection of transducer mounting integrity, quarterly descaling of the heater element using 5% citric acid solution, and annual verification of safety interlocks per manufacturer service bulletin SB-KQ-2023-01.
Is calibration documentation provided with shipment?
Yes—a factory calibration certificate (traceable to NIM, China) is included, covering temperature accuracy, timer deviation, and power output linearity at three load points.
