Supmile KQ-50E Benchtop Ultrasonic Cleaner

Overview

The Supmile KQ-50E is a compact, general-purpose benchtop ultrasonic cleaner engineered for routine laboratory cleaning tasks requiring consistent cavitation energy delivery. It operates on the principle of piezoelectric transduction: high-frequency electrical signals (40 kHz) drive ceramic transducers bonded to the stainless steel tank bottom, generating controlled acoustic pressure waves in the cleaning medium. These waves induce microbubble formation and collapse—cavitation—which mechanically dislodges particulate contaminants, organic residues, and loosely adhered biofilms from submerged surfaces. Designed for reproducible performance in non-critical applications—including glassware pre-cleaning, component degreasing, and preparatory sample handling—the KQ-50E delivers stable 50 W of effective ultrasonic power into its 2 L chamber, ensuring uniform energy distribution across the full tank volume under standard aqueous or mild solvent conditions.

Key Features

• Robust 304 stainless steel tank and housing—resistant to corrosion from water, alcohols, and common aqueous detergents; fully compliant with ISO 8573-1 for cleanroom-compatible surface finish standards.
• Electromechanical control system with rotary timer dial—enables precise manual setting of cleaning duration from 1 to 60 minutes, plus continuous (ON) mode for extended cycles; no software dependency or firmware updates required.
• Integrated sound-dampening lid—reduces airborne noise to ≤55 dB(A) at 1 m distance, meeting OSHA-recommended exposure thresholds for prolonged operator proximity.
• Optimized transducer-to-tank coupling—engineered for high electroacoustic conversion efficiency (>82% typical), minimizing reactive power draw and thermal load on internal circuitry.
• Standard stainless steel mesh basket—provides uniform sample suspension while permitting unrestricted fluid circulation around all surfaces; compatible with rack-based loading of test tubes, pipette tips, and small metal components.

Sample Compatibility & Compliance

The KQ-50E accommodates a broad range of laboratory items up to 140 mm in width and 100 mm in depth, including volumetric flasks, crucibles, syringe filters, surgical instruments, and printed circuit board assemblies. Its 40 kHz frequency provides an optimal balance between cavitation intensity and penetration depth—sufficient for removing micron-scale particles without inducing erosion on delicate optics or polished metal finishes. While not certified for sterile processing per ISO 17664 or EN 285, the unit supports GLP-aligned cleaning validation protocols when used with documented detergent concentration, temperature, and dwell time parameters. All electrical components conform to IEC 61010-1:2010 safety requirements for laboratory equipment.

Software & Data Management

The KQ-50E is a standalone hardware device with no embedded microprocessor, network interface, or digital data logging capability. This design eliminates cybersecurity vulnerabilities, firmware obsolescence risks, and calibration drift associated with embedded electronics. All operational parameters are set manually and retained only during active use; no audit trail, user access logs, or electronic records are generated—making it suitable for environments where FDA 21 CFR Part 11 compliance is not mandated, but where mechanical reliability and long-term serviceability are prioritized. For laboratories requiring traceable cleaning cycles, external timers or PLC-integrated relay controls may be interfaced via the unit’s hardwired power input.

Applications

• Pretreatment of HPLC vials and autosampler trays prior to chromatographic analysis.
• Removal of polishing compounds and machining oils from precision metrology tools.
• Cleaning of reusable filtration housings and membrane support plates in water quality testing labs.
• Deposition residue removal from quartz cuvettes and optical lens mounts in spectroscopy workflows.
• Pre-sterilization cleaning of stainless steel forceps, tweezers, and biopsy punches in pathology preparation suites.

FAQ

Is the KQ-50E suitable for cleaning delicate optics or MEMS devices?
It is not recommended for fragile coated optics or microelectromechanical systems without prior empirical validation; 40 kHz cavitation may induce surface pitting or film delamination under prolonged exposure.
Can this unit operate with solvents other than water?
Yes—compatible with isopropanol, ethanol, and aqueous alkaline detergents; avoid halogenated solvents (e.g., chloroform, carbon tetrachloride) due to transducer degradation and fire hazard.
Does the unit include temperature control or heating?
No—the KQ-50E is a non-heating model; bath temperature rise is passive and typically remains within ±3 °C of ambient during standard 10–20 min cycles.
What maintenance is required for long-term operation?
Routine inspection of tank integrity, periodic descaling with 5% citric acid solution, and visual verification of transducer bonding integrity every 12 months.
Is the stainless steel mesh basket included with every unit?
Yes—each KQ-50E ships with one 304 stainless steel mesh basket (130 × 120 × 40 mm) as standard equipment.
