Shumei KQ-200TDE Benchtop High-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-200TDE is a benchtop high-frequency digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, microfluidic devices, semiconductor wafers, and analytical instrumentation parts. It operates on the principle of cavitation-induced acoustic energy transfer: at 80 kHz, high-frequency ultrasonic waves generate controlled micro-bubbles in aqueous or compatible solvent media; their implosive collapse produces localized shear forces and micro-jetting effects that dislodge sub-micron particulates, organic residues, and thin-film contaminants without mechanical abrasion. Unlike lower-frequency units (e.g., 40 kHz), the 80 kHz frequency delivers finer cavitation bubble distribution and reduced surface erosion risk—making it especially suitable for fragile substrates such as coated lenses, MEMS sensors, and ceramic-based calibration standards. Its all-304 stainless steel tank and chamber ensure long-term corrosion resistance against mild alkaline detergents, ethanol-water mixtures, and low-concentration acidic solutions commonly used in ISO 14644-1 Class 5–7 cleanroom maintenance protocols.

Key Features

• Digital microcontroller-based operation with intuitive LED interface for simultaneous monitoring and independent adjustment of ultrasonic power (40–100% in 10% increments), heating temperature (ambient to 80 °C, ±1 °C stability), and timer duration (1–480 minutes).
• Integrated safety architecture including automatic shutdown on low liquid level detection, over-temperature cutoff (>85 °C), over-voltage and over-current protection—compliant with IEC 61010-1:2010 requirements for laboratory electrical equipment.
• High-efficiency piezoelectric transducer array optimized for 80 kHz resonance, delivering uniform energy distribution across the full 6 L tank volume (300 × 150 × 150 mm internal dimensions) with minimal standing-wave node formation.
• Sound-dampening hinged lid reduces ambient noise to ≤55 dB(A) at 1 m distance—supporting shared lab environments where acoustic interference must be minimized per ANSI S1.13-2020 guidelines.
• Modular accessory set includes 304 stainless steel mesh basket, support tray, manual drain valve, and fill port—enabling reproducible sample placement and residue-free solution exchange.

Sample Compatibility & Compliance

The KQ-200TDE accommodates a broad range of sample geometries—including pipette tips, HPLC columns, NMR tubes, crucibles, filter housings, and printed circuit board assemblies—within its 6 L capacity. Its temperature-controlled operation supports validated cleaning cycles aligned with ASTM D2606-21 (Standard Practice for Cleaning Laboratory Glassware) and USP (Cleaning Validation of Analytical Equipment). While not certified for sterile processing under ISO 13485 or FDA 21 CFR Part 820, it serves as a critical pre-sterilization step in GLP-compliant labs performing residue analysis per ICH Q5C and pharmacopeial monographs (e.g., EP 2.6.27). All wetted surfaces meet FDA-compliant material specifications for indirect food contact (21 CFR 178.3570) when used with approved cleaning agents.

Software & Data Management

As a standalone analog-digital hybrid instrument, the KQ-200TDE does not feature Ethernet, USB, or cloud connectivity. However, its non-volatile memory retains the last-used operational parameters (power %, temperature setpoint, timer value) across power cycles—ensuring procedural consistency in multi-shift laboratories. The LED display logs real-time values for temperature (set vs. measured), ultrasonic output level, and remaining time, enabling manual audit trail generation per ALCOA+ principles. For regulated environments requiring electronic records, integration with external data loggers (e.g., Omega OM-DAQPRO-5300 series) via analog voltage outputs (0–5 V DC corresponding to temperature and power status) is supported.

Applications

• Cleaning of chromatographic components (injection valves, guard columns, frits) prior to system suitability testing per USP .
• Removal of photoresist residues from photomasks and wafer carriers in microfabrication QC workflows.
• Preparation of reference standards and volumetric glassware in metrology labs adhering to ISO/IEC 17025:2017 clause 6.4.3 (equipment verification).
• Routine decontamination of reusable cell culture inserts, electrophoresis combs, and microcentrifuge tubes in academic and biotech research settings.
• Restoration of tarnished optical flats and interferometer mirrors using low-surfactant ethanol/isopropanol baths at 45 °C for 15 minutes.

FAQ

Is the KQ-200TDE suitable for cleaning aluminum or soft metal parts?

Yes—its 80 kHz frequency minimizes pitting and etching risks compared to 40 kHz systems; however, avoid prolonged exposure (>30 min) in alkaline solutions above pH 10.
Can the unit operate without heating enabled?

Yes—the heating function is fully independent; ultrasonic cleaning can be performed at ambient temperature with heater disabled.
Does it support continuous operation beyond 480 minutes?

No—the maximum timer setting is 480 minutes; for extended cycles, manual restart is required after completion.
What is the warranty coverage and service support structure?

Shumei provides a 12-month limited warranty covering parts and labor; technical documentation, firmware updates (if applicable), and application notes are available via authorized regional distributors—not direct online portals.
Are replacement transducers or control boards available separately?

Yes—original-specification transducer modules (80 kHz, 50 W nominal) and PCB assemblies are stocked by Shumei’s Jiangsu manufacturing facility and distributed through certified service partners in APAC and EMEA regions.
