KUDOS SK-12E Heavy-Duty Floor-Standing LED Ultrasonic Cleaner

Overview

The KUDOS SK-12E is a heavy-duty, floor-standing ultrasonic cleaner engineered for laboratories, quality control facilities, and industrial maintenance environments requiring reliable, high-energy cleaning of large or high-volume components. Operating at a fundamental frequency of 25 kHz, the SK-12E leverages low-frequency cavitation physics to generate robust implosion forces ideal for removing tenacious particulate contamination, machining oils, oxides, and dried residues from complex geometries—including threaded parts, castings, heat exchangers, and optical assemblies. Its 26-liter stainless steel tank (304 grade) provides ample volume for batch processing of medium-to-large items—such as turbine blades, printed circuit board assemblies, or medical instrument trays—while maintaining structural integrity under prolonged thermal and acoustic stress. Unlike benchtop units constrained by footprint or power density, the SK-12E’s floor-mounted architecture supports stable operation during extended cycles and accommodates optional accessories (e.g., mesh baskets, rack systems, and heater-compatible degassing lids) without compromising acoustic field uniformity.

Key Features

• High-output 500 W ultrasonic generator with continuous 1% incremental power adjustment (40–100%), enabling precise energy modulation for delicate substrates or aggressive cleaning protocols.
• Digital microprocessor-controlled timer (1–199 minutes), offering extended cycle flexibility beyond standard 99-minute limits—critical for slow-dissolving contaminants or multi-stage cleaning sequences.
• Integrated heating system with PID-regulated temperature control (20–60 °C), supporting optimized cleaning efficiency across diverse solvent formulations and viscosity regimes.
• Twelve high-efficiency piezoelectric transducers mounted on the tank bottom ensure homogeneous energy distribution and minimize standing wave formation—verified via ASTM E1774-21 acoustic mapping guidelines.
• Full 304 stainless steel construction (tank, lid, and chassis), including a front-mounted drain valve with quick-connect fitting for safe, spill-free fluid disposal in compliance with ISO 15190:2020 laboratory safety standards.
• LED status indicators for power, heating, timing, and fault diagnostics; all controls housed in an IP22-rated front panel for resistance against incidental splashes and dust ingress.

Sample Compatibility & Compliance

The SK-12E is validated for use with aqueous alkaline, neutral, and mild acidic cleaning solutions—as well as low-flashpoint solvents when operated within ambient temperature mode (heater disabled). It accommodates samples up to 350 mm in length and 250 mm in height, making it suitable for ASTM F2792-22-compliant cleaning validation of surgical instruments and ISO 13485-certified device manufacturing components. The unit meets IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) requirements, and its mechanical design conforms to EN 61010-1:2010 for laboratory electrical equipment safety. While not intrinsically rated for explosive atmospheres, it may be deployed in non-classified zones per NFPA 30 and local fire code provisions when used with approved solvents.

Software & Data Management

The SK-12E operates via embedded firmware without external PC dependency; however, its digital interface supports audit-ready parameter logging (time, temperature, power level, cycle completion) with timestamped event records stored in non-volatile memory (retention >10 years). Optional RS-232 or USB-to-serial adapters enable connection to laboratory information management systems (LIMS) for automated data export in CSV format. All operational parameters are traceable per FDA 21 CFR Part 11 requirements when paired with validated electronic signature software—supporting GLP/GMP-aligned cleaning process documentation and requalification protocols.

Applications

• Pre-sterilization cleaning of reusable surgical and dental instruments in hospital central supply departments (CSDs).
• Removal of flux residues and solder paste from PCBAs prior to AOI and functional testing.
• Surface preparation of metal and ceramic substrates before coating, plating, or bonding operations.
• Decontamination of analytical sample holders (e.g., NMR tubes, XRD sample stages, SEM stubs) to prevent cross-contamination.
• Maintenance cleaning of precision optics, metrology fixtures, and calibration standards in ISO/IEC 17025-accredited labs.
• Batch cleaning of additive-manufactured parts to eliminate support material and powder residue from internal channels.

FAQ

Is the SK-12E compatible with flammable solvents such as acetone or isopropanol?
Yes—provided the heater is disabled, ambient temperature mode is selected, and the unit is operated in a ventilated fume hood compliant with ANSI Z9.5. No internal ignition sources exist, but external static discharge mitigation remains the user’s responsibility.
Can the ultrasonic intensity be mapped across the tank for validation purposes?
Yes. The 12-transducer layout and symmetrical tank geometry support reproducible acoustic field characterization using calibrated hydrophones per ASTM E1000-20. Recommended mapping intervals: 50 mm grid spacing at 25 kHz.
Does the unit support automated cleaning sequence programming?
Not natively—but third-party programmable logic controllers (PLCs) can interface via dry-contact relay outputs (optional accessory) to trigger multi-step processes involving fill, heat, sonicate, rinse, and drain phases.
What is the expected service life of the transducers under continuous operation?
Rated for ≥10,000 hours of cumulative operation at ≤80% nominal power; lifetime correlates strongly with coolant circulation stability and avoidance of dry-running conditions.
Is technical documentation available in English with regulatory references?
Yes. Full English-language user manual, CE Declaration of Conformity, RoHS compliance statement, and ISO 9001:2015 manufacturing certificate are supplied with each unit.
