Supmile KQ-700V Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-700V is a benchtop ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in academic laboratories, quality control environments, and R&D facilities. It operates on the principle of ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in the cleaning solution; their implosive collapse delivers localized energy sufficient to dislodge particulate contaminants, organic residues, and biofilms from surfaces without mechanical abrasion. Designed as an integrated unit with the ultrasonic generator and stainless steel tank housed in a single enclosure, the KQ-700V eliminates external cabling complexity and improves thermal and acoustic stability. Its 27 L capacity supports medium-volume batch processing of glassware, metal parts, optical components, printed circuit boards, and small instrumentation assemblies—making it suitable for routine maintenance, pre-analytical sample conditioning, and solvent-based extraction workflows.

Key Features

• Robust 304 stainless steel V-series tank with enhanced sealing—optimized for both acoustic containment and thermal insulation to maintain consistent bath temperature during extended operation.
• High-efficiency transducer array delivering 700 W total ultrasonic power at 40 kHz, with individual elements rated at 50 W for uniform energy distribution across the entire tank volume.
• Integrated heating system (800 W) enables precise temperature control from ambient up to 80 °C—critical for enhancing detergent efficacy, accelerating dissolution kinetics, and supporting low-temperature enzymatic or chemical cleaning protocols.
• Mechanical timer with 1–20 minute adjustable range and audible end-of-cycle signal ensures repeatable process duration without software dependency—ideal for GLP-compliant environments requiring traceable, non-programmable operation.
• Sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance and minimizes evaporative loss during heated operation.
• Manual inlet and drain valves allow flexible integration into lab water supply networks or waste collection systems without reliance on fixed plumbing infrastructure.

Sample Compatibility & Compliance

The KQ-700V accommodates a broad spectrum of laboratory substrates—including borosilicate glass, aluminum, titanium, stainless steel, and certain polymer components—provided compatibility with aqueous or mild solvent-based cleaning media is verified. Its construction meets general requirements for ISO 13485-aligned cleanroom support equipment and complies with IEC 61010-1 safety standards for electrical laboratory apparatus. While not certified for medical device reprocessing under ISO 17664 or AAMI ST91, the unit is routinely deployed in pre-sterilization cleaning steps for reusable lab tools in accordance with institutional SOPs. The absence of microprocessor-based controls simplifies validation documentation for regulated QC labs operating under FDA 21 CFR Part 11–exempt workflows where manual parameter recording suffices.

Software & Data Management

The KQ-700V employs a fully analog control architecture—featuring rotary dials for time and temperature adjustment, with no embedded firmware, touchscreen interface, or data logging capability. This design prioritizes operational reliability, electromagnetic interference (EMI) immunity, and long-term serviceability over digital connectivity. All settings are directly observable and manually recorded, facilitating straightforward audit trails for ISO/IEC 17025 or CAP-accredited laboratories. No driver installation, network configuration, or cybersecurity patching is required. For users requiring electronic recordkeeping, external timers or calibrated thermometers with USB output may be employed in conjunction with validated spreadsheet templates.

Applications

• Cleaning of HPLC vials, pipette tips, filtration housings, and chromatography columns prior to analytical use.
• Degassing of solvents and mobile phases to eliminate dissolved air that may cause pump cavitation or baseline drift.
• Cell lysis and homogenization support in molecular biology workflows—particularly for tissue dissociation and subcellular fractionation when combined with appropriate lysis buffers.
• Removal of flux residues from PCBs and soldered electronic assemblies prior to X-ray inspection or functional testing.
• Preparation of calibration standards by ultrasonically dispersing reference materials in liquid matrices.
• Supporting ASTM D2622 (XRF), ISO 12185 (density), and USP particulate matter testing through contaminant-free container conditioning.

FAQ

Is the KQ-700V suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at lower time/temperature setpoints and with low-surface-tension, non-ionic detergents. However, direct contact with abrasive particles or prolonged exposure to aggressive solvents should be avoided.
Does the unit include a built-in degas mode?
No dedicated degas cycle is provided; however, operation at 40 kHz without heating for 5–10 minutes achieves effective solvent degassing in most standard applications.
Can the tank be filled with organic solvents such as acetone or isopropanol?
Only if the solvent is compatible with 304 stainless steel and the unit is used in a well-ventilated fume hood. Supmile does not validate or warranty performance with flammable liquids.
What maintenance is required for long-term reliability?
Regular descaling using dilute citric acid solution (5% w/v) every 100 operating hours prevents transducer fouling. Visual inspection of the drain valve seal and lid gasket is recommended quarterly.
Is calibration documentation available for the temperature sensor?
The unit includes a factory-calibrated NTC thermistor; users may perform field verification using a NIST-traceable immersion thermometer per ASTM E74 or ISO/IEC 17025 Annex A.3 guidelines.
