Shumei KQ-800DM Quiet-Operation Ultrasonic Cleaner

Overview

The Shumei KQ-800DM Quiet-Operation Ultrasonic Cleaner is an engineered solution for precision cleaning of laboratory glassware, optical components, precision instruments, semiconductor wafers, and medical devices. It operates on the principle of ultrasonic cavitation—generating high-frequency pressure waves (40 kHz) in a liquid medium that induce microscopic bubble formation and collapse, delivering mechanical energy to dislodge particulate contaminants, organic residues, and biofilms from surfaces without abrasion or chemical dependency. Designed for routine and critical cleaning workflows in ISO-certified labs, QC/QA environments, and R&D facilities, the KQ-800DM integrates thermal regulation, programmable timing, and power modulation to support reproducible cleaning protocols aligned with ASTM D2603, ISO 13485, and USP <788> particulate matter testing preparation guidelines.

Key Features

• Low-Noise Architecture: Acoustic enclosure design and optimized transducer mounting reduce operational noise to <60 dB(A), enabling deployment in shared lab spaces without acoustic interference or staff fatigue.
• Full-Range Power Modulation: Continuous 0–100% ultrasonic power adjustment allows precise control over cavitation intensity—critical for delicate substrates such as coated lenses, microfluidic chips, or MEMS assemblies.
• Temperature-Stabilized Cleaning: Integrated 800 W heating system with ±1 °C accuracy across 20–80 °C range supports temperature-dependent cleaning chemistries (e.g., alkaline aqueous solutions) and accelerates solvent evaporation post-rinse.
• Robust 304 Stainless Steel Construction: Seamless one-piece tank fabrication eliminates crevices for microbial retention; chassis and lid also constructed from electropolished 304 SS for corrosion resistance and cleanability per FDA-recommended equipment design principles.
• Programmable Workflow Control: Digital touchscreen interface enables storage of up to 10 user-defined cleaning cycles—including time, temperature, and power setpoints—with automatic shutdown and safety lockout upon completion or fault detection.
• Integrated Safety Systems: Real-time monitoring of liquid level, current draw, and thermal load triggers immediate shutdown under over-temperature, over-current, or dry-run conditions—ensuring compliance with IEC 61010-1 safety standards for laboratory electrical equipment.

Sample Compatibility & Compliance

The KQ-800DM accommodates a wide range of sample geometries and materials via its 30 L tank volume and modular stainless steel accessories (mesh basket, rack, and lid). It is validated for cleaning borosilicate glassware (vials, cuvettes, pipettes), stainless steel surgical tools, aluminum fixtures, and polymer-based diagnostic components. The unit meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). Its construction and operational parameters align with GLP documentation practices, supporting audit-ready traceability when paired with external logging systems.

Software & Data Management

While the KQ-800DM operates via embedded firmware without cloud connectivity, its touchscreen interface logs timestamped cycle execution data—including start/stop time, setpoint values, and fault codes—in non-volatile memory (retained for ≥10,000 cycles). Optional RS-232 or USB-to-serial interface kits enable integration with LIMS or electronic lab notebooks (ELNs) for automated record capture. All parameter changes are auditable within the device’s internal event log, satisfying basic FDA 21 CFR Part 11 requirements for electronic records when used in conjunction with procedural controls (e.g., operator ID entry via external authentication).

Applications

• Pre-analytical preparation of HPLC vials and GC autosampler trays
• Removal of flux residue from PCBs and SMT components prior to AOI inspection
• Cleaning of reusable endoscopic instrument channels and laparoscopic sheaths
• Decontamination of filtration housings and membrane filter supports
• Surface activation of PDMS microchannels prior to plasma bonding
• Routine maintenance of viscometers, density meters, and refractometer prisms

FAQ

What is the recommended cleaning solution for use with the KQ-800DM?
Aqueous alkaline or neutral pH detergents are preferred for general labware; avoid halogenated solvents unless verified compatible with 304 stainless steel and sealed transducer housings.
Can the KQ-800DM be used for sterilization?
No—it performs cleaning and soil removal only; sterilization requires validated autoclaving, ethylene oxide, or hydrogen peroxide plasma processes per ISO 17664 and AAMI ST79.
Is the timer resolution adjustable in minutes or seconds?
The timer offers 1-minute resolution across the full 0–24 h range; sub-minute intervals are not supported.
Does the unit include a degassing function?
Yes—the “degas” mode initiates low-power 40 kHz output for 5 minutes to remove dissolved air from fresh cleaning solution, enhancing cavitation efficiency.
How often should the transducers be serviced or calibrated?
Transducers require no scheduled calibration; however, periodic verification of ultrasonic output uniformity using aluminum foil test (per ASTM E1737) is recommended every 6 months in GMP-regulated environments.
