Shumei KQ5200DV Desktop Digital Ultrasonic Cleaner

Overview

The Shumei KQ5200DV is a general-purpose desktop digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, analytical instrumentation parts, optical elements, semiconductor wafers, and medical devices. It operates on the principle of cavitation—generated by high-frequency (40 kHz) acoustic energy transmitted through a liquid medium—producing microscopic implosions that dislodge particulate contaminants, organic residues, and biofilms from surfaces without mechanical abrasion. Its 13-liter stainless steel tank (300 × 240 × 180 mm internal volume), constructed entirely from corrosion-resistant 304 stainless steel, ensures long-term durability and compatibility with aqueous and mild solvent-based cleaning solutions. The unit integrates microprocessor-based control logic for stable, repeatable operation across variable load conditions and solution compositions.

Key Features

• Microcontroller-driven digital interface with real-time LED display of ultrasonic power (%), set/actual temperature, timer countdown, and water level status
• Adjustable ultrasonic output (40–100% of 200 W nominal power) enabling optimization for sensitive substrates or heavily soiled samples
• Precise temperature regulation from ambient to 80 °C via integrated 400 W heating element with PID-based thermal control
• Programmable timer spanning 1 to 480 minutes, supporting single-step or multi-cycle cleaning protocols
• Comprehensive safety architecture including low-level liquid detection, over-temperature cutoff, over-voltage and over-current protection, and automatic shutdown during dry operation
• Sound-dampening hinged lid reducing operational noise to ≤55 dB(A) at 1 m distance, improving ergonomic lab environment compliance
• Electrically actuated inlet and drain valves for automated solution fill and disposal—minimizing manual handling and cross-contamination risk
• Standard accessories include 304 stainless steel mesh basket, support tray, and lid-mounted condensate shield

Sample Compatibility & Compliance

The KQ5200DV accommodates a broad range of sample geometries and material classes—including glassware (vials, cuvettes, pipette tips), metal components (syringe needles, surgical instruments), ceramic substrates, and polymer-based microfluidic chips—provided they are chemically compatible with the selected cleaning medium. Its sealed tank design and thermal insulation meet basic ISO 13485-aligned environmental containment requirements for non-sterile pre-cleaning processes. While not certified for terminal sterilization, the unit supports cleaning validation workflows compliant with ASTM D2603 (standard test method for ultrasonic cleaning efficiency) and aligns with GLP documentation practices when integrated into controlled laboratory procedures.

Software & Data Management

The KQ5200DV employs embedded firmware—not external PC software—for all operational parameters. All settings (power %, temperature setpoint, duration) are stored in non-volatile memory and recalled upon power-up. The system logs no audit trail or timestamped event history; therefore, it is suitable for routine QC/QA applications where procedural traceability is maintained externally (e.g., via lab notebook entries or LIMS-integrated batch records). For environments requiring 21 CFR Part 11 compliance, users must implement supplementary electronic record controls outside the instrument’s native functionality.

Applications

• Routine decontamination of HPLC autosampler vials, GC injectors, and column fittings prior to calibration or reuse
• Removal of solder flux residues and oxide layers from PCB assemblies and MEMS devices
• Cleaning of microscope slides, coverslips, and optical filters without surface scratching
• Preparation of electrodes, sensors, and electrochemical cells for reproducible baseline measurements
• Supporting ASTM E1991 and ISO 12777 protocols for evaluating cleaning efficacy of critical components in regulated manufacturing
• Processing reusable PPE components (e.g., face shields, goggle lenses) in biosafety Level 2 laboratories

FAQ

Is the KQ5200DV suitable for use with flammable solvents?
No. This unit is designed exclusively for aqueous or water-miscible solutions. Flammable or low-flashpoint solvents pose fire and explosion hazards due to heating and ultrasonic energy coupling.
Does the unit support remote monitoring or data export?
No. It lacks Ethernet, USB, or RS-232 interfaces. All operation and status feedback occur locally via the front-panel display.
What maintenance is required for long-term reliability?
Regular inspection of transducer adhesion integrity, periodic descaling of the heater element using diluted citric acid, and replacement of the silicone gasket on the lid every 12–18 months under continuous use.
Can the ultrasonic frequency be changed?
No. The transducers are fixed at 40 kHz, optimized for balanced cleaning intensity and penetration depth in standard laboratory cleaning applications.
Is CE or UL certification available for this model?
The KQ5200DV complies with GB/T 14710 (Chinese national standard for environmental adaptability of medical electrical equipment) but does not carry CE, UL, or UKCA marks. Users deploying it in EU or North American facilities must verify local regulatory acceptance pathways independently.
