Shumei KQ-600TDE Benchtop High-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-600TDE is a benchtop high-frequency digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, semiconductor wafers, medical instruments, and analytical hardware. It operates on the principle of high-intensity acoustic cavitation generated at 80 kHz—optimized to deliver fine-particle removal without surface erosion or micro-scratching commonly associated with lower-frequency systems. Unlike conventional 40 kHz units, the 80 kHz frequency produces smaller, more densely distributed cavitation bubbles, enhancing cleaning efficacy on intricate geometries and sub-micron contaminants while minimizing mechanical stress on fragile substrates. The unit features a robust 304 stainless steel tank (500 × 300 × 150 mm internal volume), delivering a total working capacity of 22.5 liters—sufficient for batch processing of multiple sample holders, glassware racks, or modular fixtures. Its integrated digital control system enables precise, repeatable parameter management across diverse cleaning protocols, supporting reproducible workflows in regulated environments.

Key Features

• High-efficiency 80 kHz ultrasonic transduction with digitally adjustable output (40–100% of 600 W nominal power) for application-specific intensity tuning.
• Programmable heating system (800 W) with PID-controlled temperature regulation from ambient up to 80 °C, ensuring consistent thermal activation of cleaning solutions without overshoot or drift.
• Microprocessor-based digital interface with real-time LED display of set/actual temperature, elapsed time, power level, and liquid level status.
• Comprehensive safety architecture including automatic shutdown upon low liquid level detection, over-temperature, over-voltage, and over-current conditions—fully compliant with IEC 61010-1 electrical safety requirements.
• Sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance, meeting occupational health guidelines for continuous lab operation.
• Full 304 stainless steel construction (tank, lid, basket, and support rack) ensures long-term corrosion resistance against aqueous, alkaline, and mild solvent-based cleaning media.

Sample Compatibility & Compliance

The KQ-600TDE accommodates a broad range of sample types—including borosilicate glassware, quartz cuvettes, stainless steel surgical tools, ceramic substrates, and polymer-coated sensors—without risk of pitting or etching under controlled 80 kHz exposure. Its design conforms to standard laboratory infrastructure requirements: AC220 V / 50 Hz input, CE-marked electromagnetic compatibility (EMC Directive 2014/30/EU), and RoHS-compliant material sourcing. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its programmable logging capability (via optional RS232/USB data export) supports GLP/GMP-aligned documentation when integrated into validated cleaning SOPs per ASTM D4299 and ISO 14644-1 cleanliness verification frameworks.

Software & Data Management

The embedded firmware supports non-volatile memory retention of up to 10 user-defined cleaning programs, each storing independent settings for time, temperature, and power level. All operational parameters—including start/stop timestamps, fault codes, and real-time sensor readings—are logged internally and exportable via serial interface for audit trail generation. When connected to laboratory information management systems (LIMS), the device supports timestamped CSV output compatible with common QA/QC platforms. No proprietary software installation is required; configuration and monitoring are performed directly via the front-panel interface, eliminating driver dependencies or OS compatibility constraints.

Applications

• Cleaning of HPLC, GC, and ICP-MS sample introduction components (injector needles, nebulizers, torches) prior to trace-metal analysis.
• Preparation of TEM/SEM grids and AFM probes requiring particle-free surfaces.
• Decontamination of reusable pipette tips, centrifuge rotors, and electrophoresis combs in molecular biology labs.
• Removal of flux residues and particulate debris from PCB assemblies and MEMS devices during R&D prototyping.
• Routine maintenance of optical lenses, mirrors, and laser optics in photonics laboratories where sub-wavelength contamination must be eliminated.

FAQ

Is the KQ-600TDE suitable for use with flammable solvents?
No. This unit is designed exclusively for aqueous and water-miscible cleaning solutions. Operation with volatile organic solvents (e.g., acetone, ethanol, chlorinated hydrocarbons) is strictly prohibited due to explosion hazard and transducer degradation.
Does the device support external temperature probe input for solution monitoring?
No. Temperature sensing is performed via an integrated PT100 sensor mounted in the tank wall; external probe connectivity is not supported.
Can cleaning cycles be initiated remotely via network command?
No. Remote triggering requires third-party relay integration; the unit has no built-in Ethernet, Wi-Fi, or IoT interface.
What is the expected service life of the ultrasonic transducers under normal operating conditions?
With proper maintenance (regular descaling, avoidance of dry operation, and adherence to recommended duty cycles), transducer longevity exceeds 10,000 hours of cumulative runtime.
Is calibration documentation provided with shipment?
A factory-issued performance verification report is included, confirming frequency stability, power output accuracy (±3%), and temperature control deviation (±1.5 °C) at three load points. NIST-traceable calibration certificates are available upon request at additional cost.
