Shumei KQ-2200DE Benchtop Digital Ultrasonic Cleaner

Overview

The Shumei KQ-2200DE is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, dispersion, emulsification, and cell disruption in academic, industrial, and R&D laboratory environments. It operates on the principle of cavitation—generated by high-frequency (40 kHz) acoustic energy transmitted through liquid media—producing microscopic implosions that dislodge contaminants from surfaces and accelerate mass transfer processes. Its integrated transducer design ensures uniform energy distribution across the 3 L stainless steel tank (230 × 140 × 100 mm internal dimensions), minimizing standing wave interference and supporting reproducible cleaning outcomes. Designed for routine use in quality control labs, materials science workflows, and preparatory sample handling, the KQ-2200DE complies with fundamental safety and operational expectations for Class I laboratory equipment under IEC 61010-1.

Key Features

• Microprocessor-controlled digital interface with real-time display of set and actual temperature, elapsed time, and ultrasonic power level
• Adjustable ultrasonic power output (40–99% of nominal 100 W), enabling optimization for delicate substrates or heavily soiled components
• Precise thermostatic control (20–80 °C) with independent heating element (600 W) and PID-based regulation for stable thermal conditions during extended cycles
• Programmable timer (1–99 minutes) with automatic shutdown and audible end-of-cycle alert
• Integrated safety circuitry: low-fluid-level detection, over-temperature cutoff, over-voltage monitoring, and over-current protection
• Stainless steel tank and outer housing (grade 304 equivalent) for corrosion resistance and long-term structural integrity
• Removable stainless steel mesh basket with argon-welded construction for mechanical stability and chemical compatibility
• Acoustically insulated hinged lid to reduce ambient noise and prevent solvent evaporation during operation
• Manual inlet and drain ports for flexible fluid management without requiring permanent plumbing
• Cumulative operating hour counter (up to 999,999 h) supporting preventive maintenance scheduling and GLP-compliant usage logging

Sample Compatibility & Compliance

The KQ-2200DE accommodates a broad range of sample types—including metal parts, glassware, semiconductor wafers, optical components, ceramic filters, and biological tissue specimens—when used with appropriate aqueous or mild solvent-based cleaning solutions. Its 40 kHz frequency balances cleaning efficacy with minimal risk of surface pitting or microstructural damage to sensitive materials. The unit meets general electrical safety requirements per IEC 61010-1 and is suitable for installation in laboratories adhering to ISO/IEC 17025 environmental controls. While not certified to FDA 21 CFR Part 11 out-of-the-box, its digital parameter memory and audit-ready operating hour counter support traceability frameworks required under GLP and GMP-aligned quality systems when paired with documented SOPs.

Software & Data Management

The KQ-2200DE employs embedded firmware—not external PC software—to manage all operational parameters. All user-defined settings—including ultrasonic power percentage, target temperature, and timer duration—are retained in non-volatile memory after power cycling. The front-panel LCD displays both setpoints and real-time feedback (e.g., actual bath temperature, remaining time), enabling immediate verification of process execution. No proprietary drivers or connectivity interfaces are provided; data export is limited to visual observation and manual log entry. For regulated environments, users may integrate the unit into broader electronic lab notebook (ELN) or LIMS workflows via timestamped operator records referencing cumulative runtime and cycle parameters.

Applications

• Routine cleaning of pipettes, cuvettes, HPLC vials, and filtration apparatus prior to analytical use
• Degassing of solvents and resin mixtures prior to casting or coating applications
• Dispersion of nanoparticles and carbon nanotubes in suspension-based formulations
• Cell lysis and subcellular fractionation in molecular biology sample prep (when combined with optimized buffers)
• Removal of flux residues from printed circuit boards and microelectronic assemblies
• Preparation of homogenous colloidal suspensions for dynamic light scattering (DLS) or zeta potential analysis
• Supporting ASTM D2621 (ultrasonic cleaning validation for automotive parts) and ISO 13485-aligned cleaning verification protocols

FAQ

Is the KQ-2200DE compatible with organic solvents?
Yes, when used within manufacturer-recommended concentration limits and with adequate ventilation. Avoid halogenated solvents unless verified for compatibility with stainless steel and sealed electronics.
Does the unit support continuous operation beyond 99 minutes?
No—the maximum single-cycle timer is 99 minutes. Longer processes require manual restart or integration with external timing relays.
Can the heating function operate independently of ultrasonic activation?
Yes. Temperature control and ultrasonic generation are decoupled; either can be enabled or disabled independently.
What is the expected service life of the transducers?
Under normal use (≤8 h/day, deionized or low-conductivity water, regular descaling), transducer longevity exceeds 5,000 operating hours.
Is calibration documentation provided with the instrument?
Factory calibration certificates are not included standard; however, temperature sensor accuracy (±1 °C at 25–60 °C) and timer fidelity (<±0.5% deviation) can be verified using NIST-traceable references.
