Shumei KQ-700TDV Desktop High-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-700TDV is a desktop-grade, high-frequency digital ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, cell disruption, and solvent-based extraction in regulated laboratory environments. Unlike conventional low- to mid-frequency (20–40 kHz) ultrasonic systems, the KQ-700TDV operates at 80 kHz—enabling finer cavitation bubble collapse dynamics and significantly improved resolution for sub-micron contaminant removal from delicate substrates such as optical components, microfluidic devices, semiconductor wafers, and biological sample carriers. Its integrated transducer-and-tank architecture eliminates coupling losses associated with external transducer configurations, ensuring consistent energy delivery across the entire tank volume. The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its sealed stainless-steel construction meets ISO 14644-1 Class 8 cleanroom compatibility requirements when operated with deionized water and validated cleaning protocols.

Key Features

• High-frequency 80 kHz ultrasonic generation with digitally stabilized output—optimized for fine-particle removal without surface erosion or acoustic streaming damage.
• Full-digital parameter control via embedded microcontroller: independent adjustment of ultrasonic power (40–100%), heating temperature (10–80 °C), cleaning duration (1–480 min), and fill level (1–140 mm).
• Multi-sensor real-time monitoring: simultaneous display of actual liquid level, bath temperature, elapsed time, applied power, input voltage/current, and cumulative operational hours (up to 999,999 h).
• Integrated vapor recovery system minimizes solvent evaporation and reduces volatile organic compound (VOC) emissions—supporting compliance with OSHA 1910.1200 (Hazard Communication) and local environmental safety regulations.
• Electrically actuated inlet and drain valves enable programmable fill-and-empty cycles—critical for unattended operation in GLP/GMP-aligned workflows.
• Sound-dampening stainless-steel lid with magnetic interlock ensures operator safety and noise reduction to ≤65 dB(A) at 1 m distance.
• Stainless-steel 304 tank and housing resist corrosion from aqueous, alkaline, and mild organic solvents—including ethanol, isopropanol, and aqueous sodium hydroxide solutions.

Sample Compatibility & Compliance

The KQ-700TDV accommodates a broad range of sample geometries and materials, including glassware (vials, cuvettes, chromatography columns), metal parts (surgical instruments, watch components), ceramics (MEMS substrates), polymers (PDMS chips), and biological carriers (microcentrifuge tubes, tissue culture plates). Its 27 L capacity and 500 × 300 × 180 mm internal dimensions support batch processing of up to 24 standard 15 mL conical tubes or six 100 mm Petri dishes simultaneously. All electronic controls adhere to IEC 61010-1 safety standards for laboratory equipment. The unit supports audit-ready documentation through persistent storage of operational parameters—facilitating alignment with FDA 21 CFR Part 11 (when paired with compliant LIMS or ELN software) and ISO/IEC 17025 clause 7.7 (equipment records).

Software & Data Management

While the KQ-700TDV operates as a standalone instrument with no proprietary PC software, its digital interface logs all user-defined and real-time operational parameters into non-volatile memory. Each session record includes timestamped entries for setpoints (temperature, time, power), measured values (actual liquid level, bath temperature, voltage/current), and fault events (low-water detection, over-temperature cutoff, current surge). These data points are accessible via front-panel navigation and can be manually transcribed for inclusion in lab notebooks or electronic records. For automated integration, optional RS-232 or USB-to-serial adapters (sold separately) allow ASCII command-line control and data export in CSV format—enabling linkage with third-party data acquisition platforms compliant with ASTM E2500-22 (verification of computerized systems).

Applications

• Pre-analytical sample preparation: removal of residual proteins, lipids, and salts from HPLC vials, autosampler needles, and electrophoresis combs.
• Materials science: debubbling epoxy resins prior to casting, cleaning sputter targets, and preparing TEM grids.
• Pharmaceutical QC: cleaning dissolution apparatus vessels per USP , disintegration test baskets, and tablet friability drums.
• Biotechnology: lysing bacterial and yeast cells under controlled thermal and acoustic conditions for plasmid isolation.
• Electronics manufacturing: post-reflow flux residue removal from PCB assemblies without thermal stress or mechanical abrasion.
• Academic research: solvent exchange in nanoparticle synthesis, sonication-assisted solvent extraction of plant metabolites, and ultrasonic homogenization of lipid nanoparticles.

FAQ

Is the KQ-700TDV suitable for use with flammable solvents?
Yes—provided the unit is operated inside an explosion-proof fume hood and the solvent’s flash point exceeds the maximum bath temperature (80 °C). Do not use with diethyl ether, carbon disulfide, or other Class I liquids unless certified by your institution’s EHS office.
Can the ultrasonic frequency be changed after purchase?
No—the KQ-700TDV is factory-configured for fixed 80 kHz operation. Other TDV-series models (e.g., KQ-700TDE, KQ-700TDV-100) offer alternative frequencies (50/60/70/100 kHz), but frequency switching is not supported within a single unit.
Does the unit meet ISO 13485 requirements for medical device cleaning validation?
The KQ-700TDV provides the repeatability and parameter traceability required for IQ/OQ protocols; however, final validation must be performed per ISO 15883-1 using user-defined bioburden test soils and process-specific acceptance criteria.
What maintenance is required for long-term reliability?
Routine tasks include quarterly inspection of the stainless-steel tank for pitting, annual verification of temperature sensor accuracy (±1 °C), and replacement of the vapor condensation filter every 12 months under continuous use.
Is calibration documentation available?
Factory calibration certificates for temperature and timer functions are provided with each unit. NIST-traceable recalibration services are available through authorized Shumei service centers upon request.
