Shumei KQ-700TDE Benchtop High-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-700TDE is a benchtop digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, precision mechanical parts, and analytical instrumentation accessories. It operates on the principle of cavitation—generating high-frequency acoustic pressure waves (80 kHz) in aqueous or compatible solvent media to induce controlled microbubble formation and collapse. This transient energy release disrupts particulate adhesion, organic residues, and thin oxide layers without mechanical abrasion or thermal degradation. Designed for routine QC/QA labs, R&D facilities, and maintenance workshops, the KQ-700TDE delivers reproducible cleaning performance across diverse sample geometries and contamination profiles. Its robust 304 stainless steel tank, integrated PTC heating system, and microprocessor-controlled interface ensure stable operation under extended duty cycles while maintaining compliance with general laboratory safety and electrical standards (IEC 61010-1).

Key Features

• Microprocessor-based digital control panel with real-time display of temperature, elapsed time, power level, and water level (1–120 mm range)
• Adjustable ultrasonic power output (40–100% of 700 W nominal), enabling optimization for sensitive substrates or heavily soiled samples
• Precise temperature regulation from 10 to 80 °C via PTC surface-mounted heating elements—ensuring uniform thermal distribution and rapid stabilization
• Programmable cleaning duration from 1 to 480 minutes, with automatic shutdown and audible end-of-cycle alert
• Integrated auto-sweep frequency modulation to minimize standing wave interference and improve cleaning uniformity across the tank volume
• Comprehensive safety architecture including over-temperature, over-voltage, over-current, and low-water-level detection with visual and status-code indication
• Sound-dampening stainless steel lid reduces ambient noise levels and prevents solvent evaporation during heated operation
• Manual fill-and-drain system with ergonomic valve placement; includes stainless steel mesh basket and lid as standard accessories

Sample Compatibility & Compliance

The KQ-700TDE accommodates a wide range of sample types—including glassware (vials, cuvettes, pipette tips), metal components (syringe needles, filters, nozzles), ceramic substrates, and semiconductor wafers—provided they are chemically compatible with aqueous or mild solvent-based cleaning media. The 22.5 L tank volume supports batch processing of multiple items simultaneously, while the 500 × 300 × 150 mm internal dimensions allow vertical immersion of tall or irregularly shaped objects. All wetted surfaces are constructed from electropolished 304 stainless steel, ensuring corrosion resistance and ease of decontamination. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device’s programmable parameters, audit-ready operational logs (via optional RS232/USB data export), and deterministic process repeatability support integration into GLP- and GMP-aligned cleaning validation protocols when used with documented SOPs.

Software & Data Management

The KQ-700TDE features embedded firmware with non-volatile memory capable of storing up to 10 user-defined cleaning programs—including preset combinations of power, temperature, and time. Each program retains its last-used settings across power cycles. Optional serial (RS232) or USB connectivity enables remote parameter configuration and timestamped logging of operational events (e.g., start/stop times, fault codes, temperature excursions) for traceability in regulated environments. Data export is compatible with CSV-formatted spreadsheets for inclusion in lab notebooks or quality documentation systems. No proprietary software installation is required—basic terminal emulation or spreadsheet import suffices for review and archival.

Applications

• Cleaning of HPLC and GC autosampler vials, columns, and injector components prior to analysis
• Removal of polishing compounds and organic residues from optical lenses, mirrors, and photomasks
• Preparation of electron microscopy grids and TEM specimens requiring particle-free surfaces
• Routine decontamination of reusable pipette tips, forceps, and dissection tools in biosafety Level 2 laboratories
• Surface preparation of metallurgical samples before SEM imaging or coating deposition
• Supporting ASTM D2297 (adhesive bond cleaning), ISO 14644-1 (cleanroom component cleaning), and USP ancillary equipment hygiene requirements

FAQ

Is the ultrasonic frequency fixed at 80 kHz, or can it be changed?
The KQ-700TDE operates at a nominal frequency of 80 kHz. While the base model does not support manual frequency switching, its built-in auto-sweep function dynamically modulates the drive signal within a narrow band around 80 kHz to mitigate node/antinode effects and enhance cleaning consistency.
Can this unit be used with flammable solvents?
No. The KQ-700TDE is designed exclusively for aqueous solutions and non-flammable, low-volatility cleaning agents. It lacks explosion-proof certification and should never be operated with acetone, ethanol, or other Class I flammable liquids.
What is the maximum recommended operating temperature for continuous use?
For optimal transducer longevity and consistent cavitation efficiency, sustained operation above 60 °C is not recommended unless validated for specific solvent systems. The heater is rated for intermittent use up to 80 °C.
Does the unit include data logging capability by default?
Basic cycle counters and error logs are stored internally. Full timestamped operational data export requires connection via RS232 or USB using third-party terminal software or custom scripts.
How often should the transducers be serviced or replaced?
Under normal laboratory conditions and proper maintenance (e.g., regular tank cleaning, avoidance of dry operation), the high-frequency piezoelectric transducers exhibit service lifetimes exceeding 5,000 operational hours. Visual inspection for delamination or discoloration is advised annually.
