Overview
The Shumei KQ-700GVDV is a benchtop dual-frequency programmable ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, microfluidic devices, and precision mechanical parts. It operates on the principle of cavitation—generating controlled acoustic pressure waves in liquid media to dislodge particulate contaminants, organic residues, and biofilms from submerged surfaces. Its dual-frequency capability (45 kHz and 80 kHz) enables optimized cleaning across diverse sample geometries and contaminant types: lower frequency delivers higher cavitation intensity suitable for robust substrates and heavy particulates, while higher frequency provides finer, more uniform energy distribution ideal for microstructures, MEMS devices, and sensitive coatings. Integrated temperature control (0–80 °C), programmable timing, and power modulation allow users to define repeatable, method-driven cleaning protocols compliant with ISO 13485, ASTM D2603, and USP guidelines for cleaning validation.
Key Features
- Dual-frequency ultrasonic generation (45 kHz / 80 kHz) with user-selectable switching intervals (0–999 s), enabling adaptive cleaning strategies for heterogeneous sample loads.
- 700 W total ultrasonic output with continuous 40–100% power adjustment, ensuring reproducible energy delivery without transducer overstress.
- Precise digital temperature regulation (±2 °C accuracy) supported by 800 W heating and 350 W active cooling modules—critical for thermally sensitive samples or solvent-based cleaning processes requiring thermal stability.
- Stainless steel 304 construction throughout tank, chamber, and structural frame—resistant to corrosion from aqueous, alkaline, and mild organic solutions used in laboratory cleaning protocols.
- Integrated safety architecture including real-time liquid level sensing, dry-run prevention, over-temperature cutoff, over-voltage/current protection, and automatic shutdown upon fault detection.
- Intuitive LED display with memory function for storing up to 10 user-defined cleaning programs—including time, temperature, power, and frequency settings—for GLP-compliant workflow repeatability.
- Electrically actuated fill-and-drain system with sealed solenoid valves, eliminating manual handling and reducing operator exposure to solvents or heated media.
- Acoustically damped lid with thermal insulation, reducing ambient noise to ≤65 dB(A) at 1 m and minimizing heat loss during extended operation.
Sample Compatibility & Compliance
The KQ-700GVDV accommodates standard laboratory ware (e.g., Petri dishes, cuvettes, syringe filters, chromatography vials), surgical instruments, semiconductor wafers (up to 6-inch diameter), and custom fixtures placed on its included stainless steel mesh basket and support tray. Its 27 L capacity supports batch processing of multiple items while maintaining uniform cavitation distribution. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). All electrical components meet IP20 ingress protection requirements. For regulated environments, the device supports audit-ready documentation: all parameter changes, runtime logs, and fault events are timestamped and retained in non-volatile memory—facilitating FDA 21 CFR Part 11-aligned electronic recordkeeping when interfaced with validated LIMS or ELN platforms.
Software & Data Management
While the KQ-700GVDV operates via embedded microcontroller firmware (no external PC required), it features RS-232 serial interface for optional integration into centralized lab automation systems. Parameter logs—including start/stop timestamps, actual vs. set temperature profiles, power output history, and error codes—are exportable in CSV format for trend analysis and cleaning validation reports. Firmware supports secure configuration locking to prevent unauthorized parameter modification—a prerequisite for ISO/IEC 17025-accredited laboratories. Calibration verification points (temperature, timer, power) are accessible via service mode for periodic internal verification per ISO/IEC 17025 Clause 6.5.
Applications
- Pre-analytical sample preparation: removal of residual proteins, lipids, and salts from HPLC autosampler vials and LC-MS injection ports.
- Microelectronics: particle-free cleaning of photomasks, probe cards, and ceramic substrates prior to thin-film deposition.
- Pharmaceutical QA/QC: cleaning of dissolution apparatus baskets, tablet friability testers, and sterility test filters per USP .
- Materials science: degassing of nanoparticle suspensions and dispersion homogenization prior to TEM grid preparation.
- Medical device reprocessing: validated cleaning of endoscopic accessories and reusable surgical tools under AAMI ST79-referenced protocols.
- Academic research: reproducible surface activation of PDMS microchannels, glass slides, and quartz crystals prior to functionalization.
FAQ
What is the purpose of dual-frequency operation?
Dual-frequency ultrasonics enable selective optimization: 45 kHz enhances macro-cavitation for rapid bulk soil removal, while 80 kHz promotes micro-cavitation for gentle, high-resolution cleaning of fine features—reducing erosion risk on fragile substrates.
Does the unit support validation documentation for GMP environments?
Yes. Built-in event logging, parameter traceability, and configurable access controls align with Annex 11 and FDA 21 CFR Part 11 requirements when deployed with appropriate procedural controls and IT validation.
Can the KQ-700GVDV be used with flammable solvents?
No. This model is designed exclusively for aqueous and water-miscible cleaning solutions. Flammable solvent use requires explosion-proof certified equipment (e.g., Class I, Division 1 rated units) not provided here.
Is remote monitoring or Ethernet connectivity available?
Standard configuration includes RS-232 only. Optional RS-485 or Ethernet-to-serial gateway modules can be integrated externally for SCADA or building management system connectivity.
How often does the unit require calibration verification?
Temperature and timer functions should be verified quarterly using NIST-traceable references; ultrasonic power output verification is recommended annually using calorimetric or hydrophone-based methods per ASTM E1000.
