Supmile KQ-A1000GDE Floor-Standing Programmable Temperature-Controlled Ultrasonic Cleaner

Overview

The Supmile KQ-A1000GDE is a floor-standing, programmable ultrasonic cleaner engineered for laboratories requiring precise temperature stability during sonication. Unlike conventional ultrasonic cleaners that operate only in heating mode—or not at all—the KQ-A1000GDE integrates a closed-cycle, fluorocarbon-free refrigeration system with high-capacity resistive heating to maintain solution temperature within ±0.5 °C across the full 0–80 °C range. This dual-mode thermal regulation enables reproducible cavitation kinetics under strictly controlled thermal conditions—a critical requirement for applications such as enzymatic digestion, solvent-sensitive sample preparation, accelerated extraction protocols, and temperature-dependent dispersion or emulsification. The unit operates at a fixed frequency of 40 kHz, optimized for broad-spectrum cleaning efficacy while minimizing sample erosion in delicate substrates. Its 72-liter stainless steel tank provides scalable throughput for large batches of glassware, metal components, filtration assemblies, or multi-well plates—making it suitable for central lab facilities, QC/QA environments, and industrial R&D settings where process consistency and audit readiness are essential.

Key Features

• Programmable temperature control (0–80 °C) with integrated compressor-based cooling and 3000 W heating—enabling true isothermal sonication
• 1000 W ultrasonic power output, continuously adjustable from 400 W to 1000 W (40–100%) to match load density and substrate sensitivity
• Dual-cycle thermal management using a hermetically sealed, R134a-free compressor; eliminates refrigerant environmental concerns and ensures long-term reliability
• Robust 304 stainless steel construction for tank, lid, basket, and frame—resistant to corrosion from aqueous, alcoholic, and mild organic solvents
• Sound-dampening hinged lid with gasketed seal—reduces airborne noise to <65 dB(A) at 1 m and improves thermal retention
• Intuitive digital control panel with real-time display of temperature, time, power level, and operational status
• Manual inlet and drain valves with level-sensing compatibility—supports integration into recirculating solvent systems when paired with optional external filtration units

Sample Compatibility & Compliance

The KQ-A1000GDE accommodates a wide range of laboratory materials including borosilicate glassware, stainless steel fixtures, ceramic filters, polymer tubing, and anodized aluminum components. It is compatible with water, aqueous alkaline and acidic solutions, ethanol, isopropanol, acetone, and other low-boiling-point solvents commonly used in analytical and pharmaceutical labs. While not certified to UL/CSA or CE for standalone medical device use, its construction and control architecture align with general laboratory equipment safety expectations per IEC 61010-1. For regulated environments, the timer and temperature logging functions support basic GLP documentation; however, full 21 CFR Part 11 compliance requires external data acquisition software and audit-trail-enabled controllers (not included). The unit meets ISO 13485-aligned manufacturing standards at the OEM facility and complies with RoHS Directive 2011/65/EU regarding hazardous substances.

Software & Data Management

The KQ-A1000GDE features an embedded microcontroller-based interface with non-volatile memory for storing up to 10 user-defined programs—including temperature setpoint, ultrasonic power level, duration, and ramp profiles. All parameters are displayed on a backlit LCD with tactile membrane keys. No proprietary PC software is bundled; however, the RS-232 port (optional adapter available) permits connection to third-party SCADA or LIMS platforms for centralized monitoring. Time-stamped operational logs—including start/stop times, temperature deviations >±1 °C, and power interruption events—are retained for up to 30 days and can be exported via serial dump. For GxP environments, users may implement manual logbook entries or integrate with validated electronic lab notebooks (ELNs) that capture instrument metadata via barcode-scanned batch IDs.

Applications

• Pre-analytical cleaning of HPLC vials, GC autosampler trays, and ICP-MS nebulizer components
• Removal of biofilm and protein residues from surgical instruments and reusable labware prior to sterilization
• Ultrasonic-assisted extraction of plant metabolites, soil-bound contaminants, or polymer additives under controlled thermal conditions
• Dispersion of nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) in aqueous or polar media without thermal degradation
• Deagglomeration of ceramic powders and metal oxides for sintering feedstock preparation
• Catalytic reaction support—e.g., sonochemical synthesis of metal-organic frameworks (MOFs) where nucleation rate depends on localized temperature gradients

FAQ

Does the KQ-A1000GDE support continuous operation at elevated temperatures?
Yes—the integrated cooling system actively counterbalances resistive heating, enabling stable operation at any setpoint between 0 °C and 80 °C for durations up to 480 minutes without thermal drift exceeding ±0.5 °C.
Is the ultrasonic transducer array serviceable in the field?
Transducers are potted and permanently bonded to the tank bottom; replacement requires factory-level calibration and pressure testing. Field-service kits are not supplied.
Can this unit be used with flammable solvents?
No—this model lacks explosion-proof certification and should not be operated with solvents having flash points below 60 °C unless installed in a ventilated fume hood with vapor monitoring and intrinsically safe controls.
What maintenance is required for the refrigeration module?
The sealed compressor requires no scheduled lubrication or refrigerant recharge. Annual inspection of condenser coil cleanliness and door gasket integrity is recommended.
Is the stainless steel tank passivated per ASTM A967?
Yes—tanks undergo nitric acid passivation post-fabrication and meet ASTM A967 Method A requirements for corrosion resistance in chloride-containing environments.
