Shumei KQ-100TDE Benchtop High-Frequency Digital Ultrasonic Cleaner

Overview

The Shumei KQ-100TDE is a benchtop high-frequency digital ultrasonic cleaner engineered for laboratories requiring precise, repeatable, and contamination-sensitive cleaning protocols. Unlike conventional low- or mid-frequency units (typically operating at 25–40 kHz), the KQ-100TDE employs a stable 80 kHz piezoelectric transducer array, generating finer cavitation bubbles with higher collapse energy density per unit volume. This frequency regime enhances removal efficiency of sub-micron particulates, organic residues, and tightly adhered biofilms from delicate substrates—such as optical lenses, microfluidic chips, semiconductor wafers, and analytical sample vials—without inducing surface erosion or acoustic streaming damage. The unit integrates real-time monitoring of critical process parameters—including liquid level, bath temperature, ultrasonic power delivery, and elapsed cycle time—within a unified digital control architecture based on an embedded microcontroller platform (TDV-series firmware). Its design complies with fundamental safety and electromagnetic compatibility requirements per IEC 61000-6-3 and IEC 61000-6-4, and supports operation in ISO Class 5–7 cleanroom-adjacent environments when used with deionized water and validated cleaning solvents.

Key Features

• High-resolution 80 kHz ultrasonic generation optimized for fine-particle removal and low-surface-damage applications
• Dual-mode digital interface: simultaneous display of setpoints and real-time feedback for liquid level (1–70 mm), bath temperature (10–80 °C), ultrasonic power (%), and elapsed time (1–480 min)
• Integrated cumulative runtime counter (up to 999,999 hours) for preventive maintenance scheduling and GLP-compliant equipment log tracking
• Automatic protection logic: over-temperature cutoff, low-level fluid detection, over-current/over-voltage fault indication, and dry-run prevention
• Volatile solvent vapor recovery system minimizes airborne emissions during heated cleaning cycles with organic solvents
• Electronically actuated fill-and-drain valves enable programmable batch processing and reduce manual handling exposure
• Sound-dampening stainless-steel lid with sealed gasket reduces ambient noise to ≤55 dB(A) at 1 m distance
• 304 stainless-steel tank and housing ensure corrosion resistance, cleanability, and compliance with USP analytical instrument qualification guidelines

Sample Compatibility & Compliance

The KQ-100TDE accommodates standard laboratory glassware (e.g., volumetric flasks, cuvettes, HPLC vials), metal calibration standards, ceramic substrates, and polymer-based microdevices up to 300 × 150 × 100 mm. Its 4 L capacity and adjustable fill-level sensor allow reproducible immersion depth control—critical for ASTM D2603 (ultrasonic cleaning validation) and ISO 13485-aligned device cleaning verification. The unit supports aqueous, alcohol-based, and mild alkaline cleaning solutions; however, chlorinated or highly acidic media require external corrosion assessment per ASTM G15. While not certified to FDA 21 CFR Part 11 out-of-the-box, its digital audit trail (via stored setpoint history and runtime logs) provides foundational data integrity for internal SOPs and third-party validation under ISO/IEC 17025 or GMP Annex 15.

Software & Data Management

The TDV-series firmware enables non-volatile storage of up to 10 user-defined cleaning protocols, each retaining independent settings for frequency (fixed at 80 kHz for this model), power level, heating setpoint, duration, and fill-level target. All parameter changes are timestamped and retained across power cycles. Optional RS-232 or USB-to-serial interface (available via accessory module) permits remote command execution (e.g., START, PAUSE, RESET) and periodic data polling of operational states. Raw sensor outputs—including actual bath temperature (±0.5 °C accuracy), measured liquid level (±1 mm resolution), and real-time RMS power draw—are accessible via ASCII protocol for integration into LabVantage, STARLIMS, or custom SCADA systems. Audit trail export supports CSV formatting for traceability in regulated QC/QA workflows.

Applications

• Pretreatment of GC/MS and ICP-MS sample introduction components (injector ports, nebulizers, torches)
• Cleaning of TEM grids, AFM probes, and quartz crystal microbalance (QCM) sensors prior to surface characterization
• Deagglomeration and dispersion stabilization of nanomaterial suspensions (e.g., TiO₂, SiO₂ colloids)
• Cell lysis optimization studies in molecular biology labs using controlled sonication burst parameters
• Removal of photoresist residue and etch byproducts from MEMS fabrication masks and wafers
• Validation of cleaning efficacy per ISO 15883-5 for reusable medical device reprocessing support equipment

FAQ

Does the KQ-100TDE support frequency switching between 50–100 kHz?
No—this specific model (KQ-100TDE) is factory-configured for fixed 80 kHz operation to ensure optimal transducer coupling efficiency and thermal stability. Multi-frequency variants (e.g., KQ-100TDF) are available upon request.
Can the unit be operated without heating enabled?
Yes. The heating function is fully decoupled from ultrasonic activation; users may run cold ultrasonic cycles indefinitely with temperature setpoint disabled.
Is the PP mesh rack autoclavable?
The polypropylene rack is rated for repeated steam sterilization at 121 °C / 15 psi for up to 50 cycles; however, prolonged exposure above 100 °C may affect dimensional stability.
What is the warranty coverage and service support structure?
Shumei provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship. Technical documentation, firmware updates, and calibration templates are available through authorized regional distributors.
How is calibration verified for temperature and liquid level sensors?
Factory calibration uses NIST-traceable RTD and ultrasonic time-of-flight references. End-users may perform field verification using ASTM E74-22-compliant reference thermometers and calibrated depth gauges per documented IQ/OQ procedures.
