Supmile KQ-500GTDV Benchtop Temperature-Controlled Ultrasonic Cleaner

Overview

The Supmile KQ-500GTDV is a benchtop, digitally controlled ultrasonic cleaner engineered for applications requiring precise thermal stability during sonication. Unlike conventional ultrasonic cleaners that only heat the cleaning bath, the KQ-500GTDV integrates a closed-cycle, non-CFC refrigeration system—paired with a high-efficiency heating module—to actively maintain setpoint temperature within ±1 °C across extended operation. This dual-mode thermal regulation enables true isothermal ultrasonication, critical for temperature-sensitive processes such as botanical extraction, polymer dissolution, nanoemulsion formation, and enzymatic sample preparation. The unit operates on the principle of piezoelectric transduction at 80 kHz, generating cavitation bubbles with optimized collapse energy for efficient particle dislodgement without excessive mechanical shear. Its robust stainless-steel construction (304 grade for tank, lid, basket, and housing) ensures long-term corrosion resistance in aqueous and mild solvent environments.

Key Features

• Benchtop design with compact footprint (910 × 490 × 540 mm) and large-capacity 27 L ultrasonic tank (500 × 300 × 180 mm internal dimensions)
• Dual-mode temperature control: integrated compressor-based cooling (350 W refrigeration power) and 1000 W resistive heating for stable isothermal operation between 0 °C and 80 °C
• Digitally adjustable ultrasonic power output (40–100% of 500 W nominal), enabling optimization for delicate vs. heavily soiled samples
• Precise digital timer (1–480 minutes) with auto-shutdown and memory retention for repeatable process validation
• Acoustically insulated lid with sealing gasket to suppress airborne noise (≤65 dB(A) at 1 m) and minimize heat loss
• Electronic inlet/outlet valves for programmable fill-and-drain cycles—reducing manual handling and improving workflow consistency
• Front-panel LCD display showing real-time bath temperature, elapsed time, power level, and setpoint values

Sample Compatibility & Compliance

The KQ-500GTDV accommodates a broad range of laboratory vessels—including glass beakers, stainless-steel baskets, quartz cuvettes, and PTFE-coated fixtures—without compromising ultrasonic field uniformity. Its 80 kHz frequency provides balanced penetration depth and cavitation intensity, suitable for cleaning precision optics, surgical instruments, chromatography columns, and porous ceramic filters. All wetted components comply with ISO 8573-1 (compressed air purity) and meet material compatibility standards per USP for pharmaceutical contact surfaces. While not certified for sterile processing under ISO 13485, the unit supports GLP-compliant documentation when used with validated SOPs for cleaning verification (e.g., residue testing per ASTM E3083). Optional calibration reports traceable to NIST standards are available upon request.

Software & Data Management

The KQ-500GTDV operates via an embedded microcontroller with non-volatile memory for storing up to 10 user-defined protocols—including temperature setpoint, power level, duration, and fill/drain sequence. Though it lacks Ethernet or USB connectivity, its digital interface supports audit-ready parameter logging: all active settings and runtime events (e.g., overtemperature alerts, lid-open interruptions) are timestamped and retained for ≥100 cycles. When integrated into regulated environments, the device can be operated under FDA 21 CFR Part 11-compliant workflows using external electronic lab notebooks (ELNs) or LIMS platforms that capture operator ID, protocol version, and execution timestamps. Password-protected parameter editing prevents unauthorized configuration changes.

Applications

• Herbal extraction: Controlled-temperature ultrasonication of plant matrices (e.g., ginseng, turmeric) to enhance solute yield while preserving thermolabile actives
• Materials science: Degreasing and surface activation of carbon fiber composites, metal foams, and MEMS devices prior to coating or bonding
• Pharmaceutical R&D: Cleaning of HPLC vials, syringe filters, and dissolution apparatus parts under documented thermal conditions
• Nanotechnology: Dispersion of graphene oxide and metal-organic frameworks (MOFs) in polar solvents without aggregation
• Forensic labs: Decontamination of ballistic evidence and trace-evidence collection tools with minimal surface alteration
• Electronics manufacturing: Removal of flux residues from PCB assemblies prior to AOI inspection

FAQ

Does the KQ-500GTDV support continuous operation at sub-ambient temperatures?
Yes—the integrated refrigeration system maintains bath temperatures as low as 0 °C for up to 8 hours under standard load conditions; ambient temperature should not exceed 30 °C for optimal cooling performance.
Can the unit operate with organic solvents such as acetone or isopropanol?
It is compatible with low-boiling-point solvents only when used with the acoustic lid fully engaged and ventilation provided per OSHA 1910.1200; prolonged use of chlorinated solvents is not recommended due to potential degradation of elastomeric seals.
Is calibration documentation included with shipment?
A factory calibration certificate verifying temperature accuracy (±0.5 °C at 25 °C and 60 °C) and timer repeatability (±0.5%) is supplied; NIST-traceable recalibration services are available through authorized Supmile service centers.
What maintenance is required for the refrigeration module?
No routine refrigerant servicing is needed; users should inspect condenser coils quarterly and clean with compressed air to ensure thermal efficiency—no tools or consumables are required.
How does the electronic inlet/outlet system interface with facility water lines?
It accepts standard 3/8″ compression fittings and operates at 0.1–0.6 MPa supply pressure; flow rate is automatically modulated to achieve target fill level, minimizing overflow risk during unattended operation.
