Supmile KQ-800KDE High-Power Digital Ultrasonic Cleaner

Overview

The Supmile KQ-800KDE is a high-power, microprocessor-controlled digital ultrasonic cleaner engineered for demanding laboratory, quality control, and precision manufacturing environments. It operates on the principle of cavitation—generating high-frequency (40 kHz) acoustic pressure waves in liquid media to produce microscopic vacuum bubbles that collapse with localized energy release. This physical mechanism enables effective removal of particulate contaminants, organic residues, oils, and loosely adhered biofilms from complex geometries—including blind holes, crevices, and delicate instrumentation surfaces—without mechanical abrasion or chemical aggression. Designed as a benchtop unit with a 22.5-liter stainless steel tank (500 × 300 × 150 mm internal dimensions), the KQ-800KDE delivers consistent, reproducible cleaning performance across diverse sample types and process durations. Its robust architecture supports routine use in GLP-compliant laboratories, ISO 17025-accredited testing facilities, and regulated production settings where traceability and operational stability are critical.

Key Features

• 800 W total ultrasonic power output distributed across eight 100 W transducers mounted on the tank bottom, ensuring uniform energy distribution and minimizing standing wave interference.
• Digital microcontroller-based interface with independent, real-time displays for ultrasonic duration, set temperature, actual bath temperature, power level (%), and cumulative operating hours (up to 999,999 h).
• Adjustable ultrasonic intensity (40–100% of nominal power) to optimize cleaning efficacy while preserving sample integrity—particularly essential for fragile optics, MEMS devices, or coated substrates.
• Precise thermostatic control (20–80 °C) with ±1 °C accuracy; integrated 1000 W heating element enables rapid thermal equilibration and stable temperature maintenance during extended cycles.
• Programmable timer (1–480 minutes) with auto-shutdown and audible alert; memory retention preserves last-used parameters across power cycles.
• Comprehensive safety system including low-liquid-level detection, over-temperature cutoff, over-voltage monitoring, and over-current protection—fully compliant with IEC 61010-1 safety standards for laboratory equipment.
• Sound-dampening lid reduces ambient noise to ≤65 dB(A) at 1 m distance, improving workplace ergonomics and meeting occupational health requirements for continuous operation.

Sample Compatibility & Compliance

The KQ-800KDE accommodates a broad range of sample formats: metal and ceramic components, glassware (vials, cuvettes, pipette tips), surgical instruments, printed circuit boards, semiconductor wafers, and analytical hardware (e.g., HPLC columns, spectrometer mirrors). Its stainless steel 304 tank and argon-welded construction resist corrosion from aqueous, mild alkaline, and ethanol-based cleaning solutions. The unit meets general electrical safety requirements per IEC 61010-1 and EMC directives (EN 61326-1). While not certified for medical device reprocessing under ISO 17664 or AAMI ST79, it is widely deployed in pre-sterilization cleaning workflows aligned with ASTM F3127 (Standard Guide for Ultrasonic Cleaning Validation) and supports documentation of cleaning parameters required for internal SOPs and audit readiness.

Software & Data Management

The KQ-800KDE operates via embedded firmware without external PC dependency. All operational parameters—including time, temperature, power level, and cumulative runtime—are digitally stored in non-volatile memory and displayed in real time. Though it lacks USB/Ethernet connectivity or FDA 21 CFR Part 11-compliant electronic signatures, its deterministic parameter logging supports manual recordkeeping compatible with GLP/GMP documentation practices. Users may export cycle logs via timestamped handwritten entries or integrate the unit into broader lab management systems using external environmental data loggers (e.g., calibrated thermistors or power meters) for full traceability.

Applications

• Pre-analytical sample preparation: cleaning filtration membranes, autosampler vials, and chromatography hardware prior to HPLC/UPLC analysis.
• Electronics manufacturing: residue removal from PCB assemblies, solder paste inspection fixtures, and microelectromechanical systems (MEMS) packaging substrates.
• Materials science labs: deburring metal coupons, descaling sintered powder metallurgy parts, and preparing fracture surfaces for SEM imaging.
• Pharmaceutical QC: cleaning reusable dissolution apparatus vessels, tablet friability testers, and excipient-handling tools in accordance with USP Analytical Instrument Qualification guidelines.
• Research institutions: restoring optical components (lenses, prisms), calibrating reference standards, and maintaining vacuum chamber internals.

FAQ

What is the maximum recommended cleaning solution volume for optimal cavitation efficiency?
For the 22.5 L tank, fill to the marked “MAX” level (approximately 20 L) to ensure transducer submersion and avoid air entrapment—critical for uniform energy transmission.
Can this unit be used with flammable solvents such as acetone or IPA?
No. The KQ-800KDE is rated for aqueous and water-miscible solutions only. Flammable solvents pose fire and explosion hazards due to uncontrolled cavitation-induced heating and spark risk from electrical components.
Is the stainless steel mesh basket included with the KQ-800KDE?
Yes—a heavy-duty 304 stainless steel mesh basket is supplied as standard equipment; no plastic components contact the cleaning solution.
Does the unit support continuous operation beyond 480 minutes?
No. The built-in timer caps at 480 minutes (8 hours); for longer processes, manual restart is required after shutdown.
How often should the transducers be serviced or recalibrated?
Transducers require no routine calibration. However, annual visual inspection for delamination or corrosion at weld joints—and verification of ultrasonic output using an acoustic emission sensor—is recommended for critical applications.
