Supmile KQ-AS2000GDE Floor-Standing Temperature-Controlled Digital Ultrasonic Cleaner

Overview

The Supmile KQ-AS2000GDE is a floor-standing, digitally controlled ultrasonic cleaning system engineered for laboratories requiring precise thermal management during sonication. Unlike conventional ultrasonic cleaners that rely solely on resistive heating, the KQ-AS2000GDE integrates a sealed, non-CFC refrigeration compressor alongside PID-regulated heating elements—enabling active temperature stabilization across the full 0–80 °C range. This dual-mode thermal control ensures minimal thermal drift (< ±0.5 °C) during extended operation, critical for applications where reaction kinetics, solvent volatility, or sample integrity are temperature-sensitive. The system operates at a fixed 40 kHz frequency, optimized for broad-spectrum cavitation efficiency in aqueous and mild organic media, while its 2000 W transducer array delivers uniform energy distribution across the 800 × 500 × 400 mm tank volume. Its robust 316L stainless steel construction—including tank, lid, and mesh basket—ensures corrosion resistance against common solvents, alkaline detergents, and acidic rinse solutions.

Key Features

• Floor-standing architecture with ergonomic height (1590 × 930 × 800 mm) and integrated casters for stable repositioning in shared lab spaces
• Dual-mode temperature regulation: simultaneous heating (up to 9000 W) and active cooling (1400 W compressor), enabling isothermal sonication under exothermic or ambient-sensitive conditions
• Digital microprocessor controller with real-time display of bath temperature, elapsed time, power level, and operational status
• Adjustable ultrasonic power output (40–100% of 2000 W) via continuous duty-cycle modulation—minimizing transducer stress and extending service life
• Acoustic-damping hinged lid with safety interlock: automatically suspends ultrasonic emission when opened, reducing operator exposure to airborne cavitation noise (measured < 65 dBA at 1 m)
• Electrically actuated fill-and-drain system with programmable liquid-level sensing (10–30 mm adjustable setpoint) and solvent filtration module (optional 5-µm inline filter)
• IP54-rated electrical enclosure with redundant thermal cutoffs and overcurrent protection compliant with IEC 61010-1

Sample Compatibility & Compliance

The KQ-AS2000GDE accommodates large-format or high-volume samples including glassware sets (e.g., 20-L carboys, multi-well plate racks), metal components (surgical instruments, precision fixtures), ceramic substrates, and polymer-based labware. Its non-aggressive 40 kHz frequency minimizes pitting or surface erosion on delicate optics, MEMS devices, and coated sensors. All wetted surfaces meet ASTM A240 Type 316L specifications, ensuring compatibility with USP and ISO 13485 cleanroom-grade cleaning protocols. The system supports audit-ready documentation through optional RS-232/USB data logging (timestamped temperature, power, and cycle parameters), facilitating adherence to FDA 21 CFR Part 11 requirements when paired with validated software.

Software & Data Management

While the base unit features a standalone digital interface, an optional PC connectivity kit enables remote monitoring and parameter scripting via Supmile’s CleanLog™ LabLink software (v3.2). This application supports automated method storage (up to 99 user-defined profiles), real-time graphing of temperature vs. time curves, and CSV export for LIMS integration. Audit trails record operator ID (via optional RFID badge reader), parameter changes, and alarm events—including lid-open incidents, temperature deviation >±1.0 °C, or coolant pressure anomalies. Software validation packages (IQ/OQ documentation) are available upon request for GMP-regulated facilities.

Applications

• Pre-analytical sample preparation: removal of residual proteins, lipids, or particulates from HPLC vials, autosampler trays, and ICP-MS nebulizer components
• Pharmaceutical manufacturing: cleaning of tablet punches, capsule fillers, and stainless-steel reactor parts per USP cleaning validation guidelines
• Materials science: dispersion of nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) in aqueous colloids; degassing of polymer precursor solutions prior to spin-coating
• Electronics: flux residue removal from PCB assemblies and semiconductor wafers without thermal shock or micro-scratching
• Environmental testing labs: extraction of PAHs and PCBs from soil/sediment matrices using Soxhlet-compatible solvent cycling protocols

FAQ

Does the KQ-AS2000GDE support external temperature probe input for solution-specific monitoring?
Yes—via optional PT100 port (DIN 43760), enabling direct immersion measurement independent of tank wall thermistor feedback.
Can the system operate continuously for 48 hours under full cooling load?
Yes—validated for unattended 48-hr operation at 25 °C ambient with 100% power and 20 °C setpoint, provided adequate ventilation (minimum 500 mm rear clearance).
Is the acoustic lid compatible with fume hood installation?
Yes—the lid design maintains structural rigidity under negative pressure; optional hood-mounting brackets and vapor-tight gasket kits are available.
What maintenance intervals are recommended for the refrigeration subsystem?
Compressor oil and filter replacement every 12 months or 4000 operating hours; annual calibration of temperature sensors traceable to NIST standards.
Does the unit comply with CE electromagnetic compatibility directives?
Yes—certified to EN 61326-1:2013 (industrial environment) and EN 55011:2016 Class B for conducted/radiated emissions.
