Overview
The Supmile KQ-500TDV is a benchtop high-frequency ultrasonic cleaner engineered for precision cleaning of delicate laboratory and industrial components. It operates on the principle of cavitation—generating microscopic implosions in liquid media via high-frequency (80 kHz) acoustic energy transmitted through piezoelectric transducers bonded to the stainless-steel tank base. This frequency offers an optimal balance between cleaning intensity and sample integrity, making it especially suitable for fine optics, microfluidic devices, semiconductor wafers, precision machined parts, and analytical instrumentation components where particle removal without surface erosion is critical. The unit integrates digital microcontroller-based operation with real-time monitoring of key process parameters, enabling repeatable, traceable cleaning cycles compliant with GLP and ISO/IEC 17025 laboratory quality frameworks.
Key Features
- Digital Precision Control: Fully programmable interface with independent digital displays for elapsed time, set time, actual bath temperature, set temperature, and ultrasonic power level—ensuring full visibility and reproducibility across cleaning protocols.
- Adjustable Cavitation Intensity: Ultrasonic power output is continuously adjustable from 40% to 100% of nominal 500 W, allowing optimization for sensitive substrates (e.g., coated lenses or MEMS devices) or heavily soiled metal parts.
- Thermostatically Controlled Heating: Integrated heating system maintains bath temperature within ±1.5 °C accuracy across the 10–80 °C range, supporting temperature-enhanced cleaning chemistries and degassing prior to solvent-based processes.
- Robust Stainless-Steel Construction: The tank (500 × 300 × 180 mm internal dimensions) and mesh basket are fabricated from grade 304 stainless steel using argon arc welding—resistant to corrosion from aqueous and mild alkaline cleaning solutions.
- Acoustic Enclosure & Safety Logic: Hinged acoustic lid reduces ambient noise and prevents aerosol dispersion; automatic shutdown triggers upon low-water detection, over-temperature, over-current, or over-voltage conditions—meeting IEC 61010-1 safety requirements.
- Electric Drain System: Motorized drain valve enables hands-free, contamination-controlled solution disposal—critical for labs handling hazardous or regulated solvents under OSHA and EPA guidelines.
Sample Compatibility & Compliance
The KQ-500TDV accommodates a broad spectrum of sample geometries and materials, including glassware (vials, cuvettes, chromatography columns), metal fixtures (surgical instruments, calibration standards), ceramic substrates, and polymer-based microcomponents. Its 27 L capacity supports batch processing of multiple items simultaneously while maintaining uniform energy distribution. The unit complies with essential international standards relevant to laboratory equipment: CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); RoHS 2011/65/EU for restricted substances; and conforms to ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricating Oils) when used in tribology sample preparation. Optional documentation packages support FDA 21 CFR Part 11-compliant audit trails when integrated with validated third-party data logging software.
Software & Data Management
While the KQ-500TDV operates as a standalone instrument with embedded firmware, its digital interface outputs serial TTL-level signals (RS-232 optional via adapter) for integration into lab automation systems. Time-stamped operational logs—including start/stop timestamps, power settings, temperature profiles, and fault codes—can be captured externally for quality record retention. For regulated environments, users may implement electronic logbooks aligned with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) during routine maintenance and cleaning validation studies.
Applications
- Cleaning of HPLC/GC autosampler vials, syringe filters, and column frits prior to analytical use
- Removal of organic residues and particulates from optical components (lenses, mirrors, laser windows)
- Preparation of electron microscopy specimens requiring ultra-low particulate contamination
- Debonding and residue removal from printed circuit boards and SMT stencils
- Sanitization of reusable pipette tips and microcentrifuge tubes in molecular biology workflows
- Supporting ISO 14644-1 Class 5 cleanroom maintenance protocols through validated cleaning cycles
FAQ
Is the ultrasonic frequency fixed at 80 kHz?
Yes—the transducer array is tuned specifically to 80 kHz to maximize cavitation density while minimizing mechanical stress on fragile samples.
Can the unit be operated without heating?
Yes—temperature control is fully independent; the heater remains inactive unless explicitly enabled and set.
What type of cleaning solutions are compatible?
Aqueous alkaline, neutral, or mildly acidic formulations are recommended; avoid halogenated solvents unless confirmed compatible with stainless-steel and seal materials.
Does the electric drain require external plumbing?
The unit includes a standard 1/2″ NPT outlet; connection to floor drain or waste collection vessel is required for automated discharge.
Is calibration documentation available?
Factory calibration certificates for temperature sensor and timer accuracy are provided; periodic verification per ISO/IEC 17025 is advised using NIST-traceable references.
