Overview
The KUDOS SK-Series heavy-duty floor-standing ultrasonic cleaners are engineered for high-throughput laboratory and industrial cleaning applications where robustness, consistent cavitation energy delivery, and long-term operational stability are critical. Operating at a fixed frequency of 25 kHz, these units leverage low-frequency ultrasonic energy to generate intense cavitation bubbles in aqueous or compatible solvent-based cleaning solutions—ideal for removing particulate contaminants, oils, greases, oxides, and biological residues from complex geometries including surgical instruments, precision optics, metal parts, glassware, and printed circuit boards. Unlike benchtop models, the SK-Series features a reinforced structural frame, floor-mounted footprint, and integrated drainage system—designed for continuous use in QC labs, medical device reprocessing units, and manufacturing cleanrooms. The LED display provides real-time visibility of elapsed time during operation, supporting adherence to standardized cleaning protocols without reliance on external timers.
Key Features
- Industrial-grade construction with fully welded 304 stainless steel tanks and external cabinets rated for sustained duty cycles
- High-power transducer arrays (12–36 units depending on model) optimized for uniform energy distribution across large tank volumes
- Digital timer with precise 1-minute resolution; extended range up to 199 minutes on SK-24E and SK-36E models for prolonged soak-and-clean cycles
- Integrated 304 stainless steel drain valve positioned at the lowest point of the tank for complete solution evacuation and reduced cross-contamination risk
- LED display interface offering clear visibility under ambient lab lighting; no touch-sensitive or membrane-based controls susceptible to liquid ingress
- Fixed-frequency 25 kHz generator architecture ensures stable acoustic output without harmonic drift—critical for repeatable cleaning validation
- Compliance-ready design: all electrical components meet IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards; CE-marked per Machinery Directive 2006/42/EC
Sample Compatibility & Compliance
These ultrasonic cleaners accommodate a wide range of sample types—including stainless steel, titanium, aluminum, borosilicate glass, and anodized surfaces—provided appropriate cleaning chemistries are selected to avoid pitting or etching. The absence of temperature control limits use to ambient-temperature processes only, making them suitable for thermally sensitive substrates or when heat-induced degradation of contaminants must be avoided. While not certified for sterile processing per ISO 17664 or AAMI ST79, the SK-Series supports GLP-aligned cleaning validation when paired with documented cleaning agents, calibrated timers, and post-cleaning residue testing (e.g., ATP bioluminescence or gravimetric residue analysis). Units are compatible with common alkaline, neutral, and enzymatic formulations used in pharmaceutical equipment cleaning (per USP Analytical Instrument Qualification guidance).
Software & Data Management
The SK-Series operates as a standalone hardware platform with no embedded software, network connectivity, or data logging capability—intentionally designed to minimize complexity, cybersecurity exposure, and regulatory qualification burden. All operational parameters (timer setting, power-on state) are retained only during active use and reset upon power cycling. This architecture aligns with FDA 21 CFR Part 11 expectations for “non-critical” ancillary equipment: audit trails are maintained externally via lab notebook entries or electronic batch records, and instrument calibration is verified through periodic verification of timer accuracy (±1% tolerance) and transducer output consistency using calibrated hydrophones or calorimetric methods.
Applications
- Pre-sterilization cleaning of reusable surgical and dental instruments prior to autoclaving or ethylene oxide treatment
- Removal of polishing compounds and buffing residues from optical lenses and metrology components
- Decontamination of sampling probes, pipette tips, and HPLC vial racks in analytical laboratories
- Cleaning of engine parts, fuel injectors, and aerospace components in maintenance facilities
- Supporting ASTM D2240 (Shore hardness) sample preparation by eliminating surface contaminants affecting indentation readings
- ISO 8573-1 compressed air system component cleaning to prevent particulate carryover into critical pneumatic circuits
FAQ
Is temperature control available on this series?
No. The SK-Series operates at ambient temperature only; no heating element or thermostat is included.
Can these units be used with flammable solvents?
No. These cleaners are designed exclusively for aqueous or water-miscible solutions; use with flammable solvents poses fire and explosion hazards and voids warranty and safety certifications.
What is the expected transducer service life under normal laboratory use?
Based on accelerated life testing and field data, transducers maintain ≥90% nominal output after 10,000 hours of cumulative operation when operated within specified duty cycles (≤8 hrs/day, with 15-min cooldown between cycles).
Does KUDOS provide IQ/OQ documentation templates?
Yes—validated installation and operational qualification templates compliant with ISO/IEC 17025 and GMP Annex 15 are available upon request for qualified purchasers.
Are replacement tanks or transducer assemblies available as spare parts?
Yes. All major subassemblies—including full tank modules, transducer plates, and power supply units—are stocked and supplied with traceable serial numbers and material certifications (EN 10204 3.1).
