Shumei KQ5200DM Quiet-Operation Ultrasonic Cleaner

Overview

The Shumei KQ5200DM Quiet-Operation Ultrasonic Cleaner is an engineered solution for precision cleaning of delicate laboratory components, optical elements, precision instruments, and small-volume sample containers. It operates on the principle of ultrasonic cavitation—generating high-frequency mechanical oscillations (40 kHz) in liquid media to produce transient microbubbles that collapse with localized energy release, effectively dislodging particulate contaminants, organic residues, and biofilms from surfaces without mechanical abrasion. Designed for routine use in QC labs, research facilities, and analytical service centers, the KQ5200DM delivers reproducible cleaning performance across diverse sample geometries while maintaining strict acoustic and thermal control parameters.

Key Features

• Low-noise operation (<60 dB[A]) achieved through integrated acoustic-dampening lid, optimized transducer mounting, and vibration-isolated tank structure—critical for shared lab environments where ambient noise must comply with ISO 14040-compliant workspace standards.
• Full-range ultrasonic power modulation (0–100% in continuous analog adjustment), enabling method optimization for sensitive substrates such as coated lenses, MEMS devices, or chromatography vials without risk of surface pitting or delamination.
• Precision temperature control (ambient to 80 °C) supported by a 400 W heating system with PID-based regulation, ensuring consistent thermal conditions during warm cleaning cycles required for lipid or polymer residue removal per ASTM D4928-21 guidelines.
• One-piece deep-drawn 304 stainless steel tank—electropolished finish, seamless interior, and corrosion-resistant construction—meets ISO 15190:2020 requirements for laboratory equipment material compatibility with common aqueous and mild solvent-based cleaning solutions.
• Dual safety architecture: real-time liquid-level detection prevents dry-run damage; independent over-temperature and over-current protection circuits ensure compliance with IEC 61010-1 safety standards for laboratory electrical equipment.
• Intuitive LCD touch interface with non-volatile timer memory (0–24 h), allowing unattended operation and repeatable protocol execution—essential for GLP-aligned cleaning validation workflows.

Sample Compatibility & Compliance

The KQ5200DM accommodates standard laboratory ware including volumetric flasks (up to 1000 mL), HPLC vials, cuvettes, pipette tips, surgical instruments, and printed circuit board assemblies. Its 300 × 240 × 150 mm internal tank dimensions support multi-tiered loading via included stainless steel rack and mesh basket. The unit complies with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), conforms to RoHS 2011/65/EU material restrictions, and supports traceable cleaning documentation when integrated into FDA 21 CFR Part 11–compliant laboratory information management systems (LIMS) via external logging interfaces.

Software & Data Management

While the KQ5200DM operates as a standalone benchtop instrument with embedded firmware, its programmable parameters—including power level, temperature setpoint, and cycle duration—are fully recordable via manual log sheets or external data acquisition systems. For regulated environments, users may integrate time-stamped operational logs (start/end time, max temperature reached, actual power applied) into electronic batch records. The device’s stable thermal and acoustic output profile enables qualification under IQ/OQ protocols per GAMP 5 Annex 11 principles, supporting audit readiness for ISO/IEC 17025-accredited testing laboratories.

Applications

• Cleaning of glassware and quartz cuvettes prior to UV-Vis or fluorescence spectroscopy to minimize scattering artifacts.
• Preparation of GC/MS inlet liners and syringe needles to eliminate carryover contamination.
• Removal of flux residues from PCBs in electronics reliability testing labs.
• Decontamination of reusable surgical tools in biomedical research settings following EN ISO 15883-1 sterilization preprocessing guidelines.
• Routine maintenance of weighing boats, spatulas, and filtration apparatus in pharmaceutical QC labs adhering to USP cleaning validation expectations.

FAQ

Is the KQ5200DM suitable for use with flammable solvents?
No. This unit is designed exclusively for aqueous and water-miscible cleaning solutions. Use with volatile organic solvents requires explosion-proof certification not provided with this model.
Can the ultrasonic frequency be changed?
No. The transducer assembly is fixed at 40 kHz, optimized for broad-spectrum contaminant removal while balancing penetration depth and surface shear stress.
What is the expected lifetime of the piezoelectric transducers?
Under normal operating conditions and adherence to recommended duty cycles (≤8 h/day continuous use), transducers maintain ≥95% nominal power output for ≥5 years, per accelerated life testing per IEC 60068-2-64.
Does the unit include validation documentation?
Factory calibration certificates for temperature and timer accuracy are available upon request. Full IQ/OQ documentation packages may be developed in collaboration with certified third-party service providers.
How is drainage performed?
Manual drain valve located at the rear-bottom of the tank; no pump or automatic siphon system is integrated—user-controlled emptying ensures full process transparency and avoids cross-contamination risks.
