Overview
The Supmile KQ-100VDB is a benchtop dual-frequency ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, electronic assemblies, and small-volume analytical hardware. It operates on the principle of acoustic cavitation—generating high-intensity micro-bubbles in liquid media through piezoelectric transducers mounted to the stainless steel tank base. The simultaneous or alternating application of two discrete ultrasonic frequencies (45 kHz and 80 kHz) enables optimized removal of diverse contaminant types: lower frequency (45 kHz) delivers higher energy cavitation suitable for particulate and adhesive residue, while the higher frequency (80 kHz) produces finer, more uniformly distributed bubbles ideal for sub-micron particle detachment from intricate geometries and sensitive surfaces. This dual-frequency architecture enhances cleaning efficacy across heterogeneous sample sets without requiring manual reconfiguration or solvent switching—making it particularly valuable in QC laboratories, R&D facilities, and instrument maintenance workflows where reproducibility and process standardization are critical.
Key Features
- Dual-frequency operation (45 kHz / 80 kHz) with programmable frequency switching interval (1–999 s), supporting adaptive cleaning strategies for mixed-load batches.
- Digital microprocessor control system with non-volatile memory for retaining user-defined parameters—including ultrasonic power level (40–100% in 1% increments), heating setpoint (10–80 °C), and timer duration (1–480 minutes).
- Integrated safety circuitry providing real-time monitoring and automatic shutdown for low liquid level, over-temperature (>85 °C), over-voltage (>±10% nominal), and over-current conditions.
- Stainless steel tank (300 × 150 × 100 mm internal) formed by deep-drawn stamping and argon arc welding—ensuring structural integrity, corrosion resistance, and long-term dimensional stability under thermal cycling.
- Removable stainless steel mesh basket with reinforced perimeter welds; compatible with standard laboratory fixtures and compliant with ISO 13485-referenced handling protocols for medical device component cleaning.
- Cumulative operating hour counter with battery-backed memory—supporting preventive maintenance scheduling and GLP-compliant equipment usage logs.
Sample Compatibility & Compliance
The KQ-100VDB is validated for use with aqueous, mild alkaline, and low-concentration detergent solutions commonly employed in ISO 15883-1–compliant cleaning processes. Its 3 L capacity accommodates standard volumetric flasks (up to 1 L), HPLC vials, pipette tips, microscope slides, and small mechanical parts. The absence of a sound-dampening lid necessitates operation in controlled ambient noise environments but facilitates rapid solution exchange and visual monitoring during critical cleaning cycles. While not certified to UL/CSA or IEC 61010-1 as a standalone medical device, the unit meets general electrical safety requirements for Class I laboratory equipment per GB 4793.1 (China’s equivalent to IEC 61010-1). For regulated applications—including pharmaceutical equipment cleaning validation—the device supports documented parameter traceability via its digital interface and may be integrated into broader cleaning SOPs aligned with USP , ASTM D2603, and ISO 13408-1 guidelines.
Software & Data Management
The KQ-100VDB employs embedded firmware—not external PC software—to manage all operational parameters. All settings are stored in EEPROM with write-protection logic, ensuring data persistence across power cycles. The display shows real-time values for actual bath temperature (±1.5 °C accuracy), elapsed time, and active frequency mode. Though lacking network connectivity or FDA 21 CFR Part 11–compliant audit trail functionality, the unit supports manual documentation workflows: users can record timestamped parameter configurations alongside batch identifiers in laboratory notebooks or LIMS entries. Cumulative runtime data assists in establishing service intervals per manufacturer-recommended maintenance schedules (e.g., transducer inspection every 2,000 hours of operation).
Applications
- Cleaning of HPLC injection needles, autosampler vials, and column frits prior to chromatographic analysis.
- Preparation of electron microscopy grids and TEM specimen holders to minimize carbon contamination.
- Removal of flux residues and oxidation films from PCB prototypes and microelectromechanical systems (MEMS) substrates.
- Routine decontamination of reusable pipette tips, crucibles, and weighing boats in analytical chemistry labs.
- Supporting ASTM E1945–standardized validation of cleaning effectiveness for glassware used in trace metal analysis.
- Assisting ISO 13485-certified manufacturers in achieving repeatable pre-sterilization cleaning of surgical instrument components.
FAQ
Is the KQ-100VDB compliant with FDA 21 CFR Part 11 for electronic records?
No. The unit lacks user authentication, electronic signature capability, and immutable audit trails required for Part 11 compliance. It is intended for use in non-GxP environments or as part of manually documented cleaning processes.
Can the unit operate continuously for extended periods?
Yes—within thermal limits. Continuous operation is permissible up to 8 hours per cycle, provided ambient temperature remains ≤30 °C and cooling airflow around the base is unobstructed. Duty cycle recommendations: 30 min on / 10 min off for >4-hour sessions.
What cleaning solutions are compatible with the stainless steel tank?
Aqueous alkaline detergents (pH 9–11), ethanol/water mixtures (<50% v/v), and low-foaming enzymatic formulations. Avoid halogenated solvents, strong acids (e.g., HCl, HNO₃), and undiluted oxidizers, which may accelerate passive layer degradation.
Does the unit include a degassing function?
No dedicated degas mode is provided. However, initiating ultrasonication at 45 kHz for 2–3 minutes before sample immersion effectively reduces dissolved gas content in fresh solutions.
How is calibration verified for temperature and timer accuracy?
Temperature calibration requires external NIST-traceable thermometry (e.g., calibrated Pt100 probe); timer accuracy is factory-verified to ±0.5% deviation over 24 h. Users should perform periodic verification per internal QA procedures.
