KUDOS SK3200HP Benchtop Ultrasonic Cleaner with Adjustable Power Output

Overview

The KUDOS SK3200HP is a precision-engineered benchtop ultrasonic cleaner designed for consistent, reproducible cleaning of delicate laboratory components—including glassware, pipette tips, microcentrifuge tubes, optical lenses, and precision metal parts—without mechanical abrasion or thermal degradation. Operating on the principle of acoustic cavitation at a fixed frequency of 53 kHz, the unit generates high-intensity ultrasonic waves in liquid media, inducing controlled microbubble formation and implosion that dislodge sub-micron contaminants from surfaces. Unlike heating-based cleaning systems, the SK3200HP maintains ambient bath temperature during operation (no integrated heater), making it suitable for thermally sensitive samples and solvents with low flash points. Its compact footprint (330 × 180 × 240 mm) and 4.5 L stainless-steel tank (304 grade) conform to ISO 8573-1 cleanroom-compatible material standards and resist corrosion from common aqueous and mild organic cleaning solutions.

Key Features

• Precision digital power control: Continuous 40–100% output adjustment in 1% increments, enabling method optimization for varying sample loads, soil types, and solvent viscosities.
• Backlit LCD interface with real-time display of elapsed time, set duration, active power level (%), and bath temperature (via integrated sensor).
• Non-volatile memory retains user-defined parameters—including timer setting and power level—after power interruption, supporting GLP-compliant workflow continuity.
• Robust 304 stainless-steel transducer-bonded tank ensures long-term structural integrity and resistance to alkali, acid, and halogenated solvent exposure.
• Digital timer with 1–199 minute range allows precise exposure control for validation-driven cleaning protocols per ASTM D2603 or ISO 13485 Annex A guidelines.
• Integrated support rack (stainless steel) elevates samples above tank bottom to prevent redeposition of dislodged particulates and ensure uniform energy distribution.

Sample Compatibility & Compliance

The SK3200HP accommodates a broad range of sample geometries up to 300 × 150 mm base area and 100 mm immersion depth. It is routinely deployed for pre-analytical preparation of HPLC vials, SEM stubs, surgical instruments, and MEMS devices. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for laboratory electrical equipment). While not certified for sterile processing under ISO 17664 or EN 13060, its repeatable cavitation performance supports cleaning validation studies required by FDA 21 CFR Part 211 (for pharmaceutical manufacturing) and ISO 15883-1 (for reprocessing of medical devices). All materials in contact with cleaning solution meet USP Class VI biocompatibility criteria.

Software & Data Management

The SK3200HP operates as a standalone instrument with no external software dependency. However, its parameter retention functionality—preserving last-used settings across power cycles—enables traceable operation within paper-based or electronic lab notebook (ELN) workflows. For audit readiness, users may manually log timestamped entries including batch ID, cleaning duration, power setting, solvent type, and visual inspection outcome. The absence of network connectivity or remote control interfaces aligns with cybersecurity best practices outlined in NIST SP 800-53 Rev. 5 for non-networked laboratory instrumentation.

Applications

• Removal of organic residues (e.g., oils, greases, fingerprints) from optical components prior to interferometric measurement.
• Decontamination of reusable chromatography fittings and filter housings to prevent cross-sample carryover.
• Pre-cleaning of electron microscopy grids and TEM specimen holders to minimize carbon contamination artifacts.
• Routine maintenance of pH electrodes, conductivity cells, and dissolved oxygen sensors to restore calibration stability.
• Supporting ISO/IEC 17025 accredited laboratories in developing documented cleaning SOPs with defined acceptance criteria (e.g., water-break test, particle count post-rinse).

FAQ

Does the SK3200HP include a heating function?
No. This model operates at ambient temperature only; it does not incorporate a heating element. Temperature-sensitive samples and low-boiling-point solvents can be safely processed.
Is the ultrasonic frequency adjustable?
No. The unit operates exclusively at 53 kHz—a frequency optimized for general-purpose cleaning with balanced penetration depth and cavitation intensity.
Can the timer be paused mid-cycle?
No. Once initiated, the timer runs continuously until completion or manual shutdown. Interruption requires resetting the timer and power level.
What is the expected service life of the transducers under normal use?
With proper degassing, regular descaling (using 5% citric acid solution every 200 operating hours), and avoidance of dry operation, transducers maintain >95% nominal power output for ≥5,000 hours of cumulative runtime.
Is third-party calibration available for this model?
Yes. Accredited metrology providers offer traceable verification of timer accuracy (±0.5 s/min) and power delivery consistency (±3% of setpoint) per ISO/IEC 17025 scope.
