Shumei KQ-100DE Benchtop Digital Ultrasonic Cleaner

Overview

The Shumei KQ-100DE is a benchtop digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, filters, microplates, optical lenses, and small metal parts—where manual scrubbing risks damage or contamination. It operates on the principle of cavitation: high-frequency (40 kHz) ultrasonic energy generates microscopic vacuum bubbles in the cleaning solution; their rapid collapse produces localized shockwaves and microstreaming that dislodge particulate matter, organic residues, and biofilms from surfaces without mechanical abrasion. This physical cleaning mechanism ensures consistent, non-destructive decontamination across complex geometries and blind holes—critical for QC/QA labs, analytical chemistry workflows, and pre-analytical sample preparation. The unit integrates a digitally controlled heating system (10–80 °C), enabling temperature-assisted cleaning for viscous or thermally sensitive contaminants while maintaining thermal stability within ±2 °C under load.

Key Features

• Digital microcontroller-based operation with real-time display of ultrasonic power (%), set/actual temperature (°C), and remaining time (min); retains last-used parameters upon power cycle.
• Full 304 stainless steel construction—including tank, lid, basket, and support frame—for corrosion resistance, long-term structural integrity, and compliance with ISO 15190:2020 laboratory safety standards.
• Adjustable ultrasonic power output (40–100% of 100 W nominal) to optimize energy delivery for varied sample loads and soil types—reducing unnecessary cavitation erosion on fragile substrates.
• Independent temperature control with 400 W heating element and PID-regulated feedback loop; supports both ambient-temperature degassing and elevated-temperature cleaning protocols.
• Programmable timer (1–480 minutes) with automatic shutdown and audible end-of-cycle alert; compatible with unattended overnight operation under supervised lab conditions.
• Integrated sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance, meeting OSHA 29 CFR 1910.95 workplace noise exposure guidelines.
• Comprehensive digital protection suite: over-temperature cutoff (≥85 °C), over-voltage lockout (>242 V), and over-current detection—logically interlocked with ultrasonic transducer activation.

Sample Compatibility & Compliance

The KQ-100DE accommodates standard laboratory items up to 300 mm × 150 mm × 100 mm in volume, including volumetric flasks, crucibles, chromatography vials, and semiconductor wafers (with optional custom racks). It is compatible with aqueous alkaline, acidic, and enzymatic cleaning solutions—as well as low-surface-tension solvents such as isopropanol and ethanol—provided vapor pressure and flash point are considered per NFPA 30. The unit meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and electrical safety (EN 61010-1). While not certified for sterile processing per ISO 13485, it supports GLP-compliant cleaning validation when integrated into documented SOPs with traceable parameter logging (via external data logger).

Software & Data Management

The KQ-100DE operates via embedded firmware with no PC connectivity or proprietary software. All operational parameters are stored in non-volatile memory and displayed on a 4-digit LED screen. For laboratories requiring audit trails, users may integrate the unit into validated workflows by recording setpoints, durations, and observed outcomes in electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11—using timestamped operator entries and dual-signature review. No internal data storage or network interface is present; this design minimizes cybersecurity risk and aligns with NIH and EU-OSHA recommendations for standalone instrumentation in regulated environments.

Applications

• Pretreatment of HPLC/GC autosampler vials and injection ports to prevent carryover and baseline drift.
• Removal of polishing compounds and oxide layers from metallurgical samples prior to SEM/EDS analysis.
• Cleaning of quartz cuvettes and optical filters used in UV-Vis spectrophotometry to eliminate scattering artifacts.
• Decontamination of reusable surgical instruments in research animal facilities (non-sterile level).
• Preparation of electrode surfaces in electrochemical cell assembly to ensure reproducible charge-transfer kinetics.
• Routine maintenance of microfluidic chips and PDMS molds to restore hydrophilicity and channel fidelity.

FAQ

Is the KQ-100DE suitable for cleaning delicate optics or MEMS devices?

Yes—when operated at 40–60% power and 25–40 °C with deionized water or low-concentration surfactant solutions, it effectively removes submicron particles without surface pitting or coating delamination.
Can the unit be used with flammable solvents?

No. It lacks explosion-proof certification and active vapor management; only aqueous or high-flash-point (>60 °C) solvents should be used per manufacturer guidance and local fire codes.
Does it support continuous operation beyond 480 minutes?

No—the maximum timer setting is 480 minutes; extended cycles require manual restart after completion.
What maintenance is required for long-term reliability?

Monthly inspection of tank integrity, quarterly descaling with 5% citric acid solution, and annual verification of temperature accuracy using NIST-traceable probe.
Is calibration documentation provided?

The unit ships with a factory test report (including power output verification at 40/70/100% settings and temperature uniformity mapping); formal calibration certificates are available upon request for an additional fee.
