KUDOS SK-12C/SK-18C/SK-24C/SK-36C Floor-Standing Ultrasonic Cleaner with LCD Control Panel

Overview

The KUDOS SK-series floor-standing ultrasonic cleaners are engineered for high-efficiency, large-volume cleaning of laboratory glassware, metal components, precision instruments, and industrial parts. Operating at a fixed frequency of 25 kHz, these units leverage robust piezoelectric transducer arrays bonded to the tank bottom to generate intense cavitation fields within aqueous or compatible solvent media. Unlike higher-frequency cleaners optimized for delicate microstructures, the 25 kHz frequency delivers greater mechanical energy per cavitation collapse—making the SK-series especially effective for removing tenacious particulates, dried residues, machining oils, and biofilm from surfaces with complex geometries or heavy soiling. Designed as freestanding units with integrated LCD control panels, they eliminate benchtop space constraints and support continuous operation in QC labs, maintenance workshops, and production environments where throughput and reliability are critical.

Key Features

• Four scalable models (SK-12C, SK-18C, SK-24C, SK-36C) offering tank capacities from 26 L to 123 L—enabling selection based on batch size and part dimensions.
• Precision digital power regulation: adjustable from 40% to 100% of nominal output in 1% increments, allowing fine-tuned energy delivery to match substrate sensitivity and soil type.
• Microprocessor-controlled timer with 1–99 minute range, supporting repeatable process validation and integration into standardized cleaning SOPs.
• High-density transducer arrays (12–36 units per tank), uniformly distributed and acoustically coupled to 304 stainless steel tanks for consistent energy distribution and minimized dead zones.
• Integrated 304 stainless steel drain valve with threaded outlet—facilitating rapid, spill-free solution exchange and residue removal between cycles.
• Front-panel LCD interface with intuitive icon-based navigation, real-time parameter display, and non-volatile memory for saving frequently used settings.

Sample Compatibility & Compliance

These ultrasonic cleaners accommodate a broad range of sample types including volumetric flasks, burettes, pipette tips, surgical tools, filter housings, and machined aluminum or stainless-steel assemblies. The 25 kHz frequency is compatible with standard aqueous alkaline, neutral, and mild acidic cleaning solutions; compatibility with organic solvents (e.g., isopropanol, acetone) requires verification per manufacturer safety data sheets and local ventilation requirements. All SK-series units comply with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). While not certified to UL/CSA or CE for medical device reprocessing, they meet general-purpose laboratory equipment requirements under ISO/IEC 17025-aligned facility operations. For GMP-regulated environments, users may configure audit trails via external logging systems; the unit itself does not include FDA 21 CFR Part 11-compliant electronic signatures or user access controls.

Software & Data Management

The SK-series operates via embedded firmware without external PC dependency. All operational parameters—including elapsed time, set power level, and active cycle status—are displayed and retained in volatile memory during operation. No proprietary software, USB connectivity, or network interface is provided. However, the precise repeatability of timer and power settings supports manual documentation in paper-based or LIMS-integrated logbooks. Users requiring automated data capture may integrate the unit into broader lab automation workflows using dry-contact relay outputs (optional accessory—not included) triggered at cycle completion.

Applications

• Routine decontamination of reusable labware prior to sterilization or analytical use.
• Preparation of sampling equipment for environmental or pharmaceutical testing (e.g., TOC vials, HPLC autosampler trays).
• Cleaning of optical components, semiconductor fixtures, and MEMS devices where particle counts must be reduced below ISO Class 5 thresholds.
• Maintenance of analytical instrumentation—such as AAS nebulizers, ICP-MS spray chambers, and GC inlet liners.
• Removal of flux residues and solder paste from PCB assemblies in R&D prototyping labs.
• Supporting ASTM D2247 (standard practice for cleaning metal specimens) and ISO 15528 (paints, varnishes, and raw materials) sample preparation protocols.

FAQ

Is temperature control available on this model?

No—these units operate at ambient temperature only. They do not incorporate heating elements or thermostatic regulation.
Can the timer be extended beyond 99 minutes?

No—the maximum preset duration is 99 minutes. For longer cycles, users must manually restart the timer after completion.
Are replacement transducers or tanks available as spare parts?

Yes—KUDOS provides OEM transducer modules and full tank assemblies under part numbers aligned to each SK model; lead times vary by region.
Does the unit include degassing functionality?

No—degassing must be performed externally or via manual “pulse” mode (if enabled by local firmware version); no dedicated degas cycle is implemented.
What electrical supply is required?

All models require a grounded 220–240 V AC, 50 Hz single-phase supply with circuit protection rated ≥16 A. Voltage tolerance is ±10%; use of an isolation transformer is recommended in labs with unstable mains.
