KUDOS SK2200HP/SK3200HP/SK3300HP/SK5200HP Series Benchtop Ultrasonic Cleaner with Continuously Adjustable Power Output

Overview

The KUDOS SK-Series benchtop ultrasonic cleaners are engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, filtration membranes, microfluidic devices, and analytical sample holders—using high-frequency acoustic cavitation at a stable 53 kHz operating frequency. This frequency balances cleaning efficacy with minimal risk of surface erosion or structural damage to sensitive substrates. Unlike fixed-power units, the SK-Series incorporates a digitally controlled, continuously variable power delivery system that allows operators to fine-tune output from 40% to 100% of maximum rated power (100–500 W depending on model) in precise 1% increments. This granular control enables method optimization across diverse sample matrices—from light particulate removal on optical lenses to robust contaminant dislodgement from sintered metal filters—without requiring hardware changes or external attenuators. The unit operates without integrated heating; however, ambient liquid temperature is monitored and displayed in real time via the backlit LCD interface, supporting thermal stability documentation for GLP-compliant workflows.

Key Features

• Digital backlit LCD interface with intuitive on-screen menu navigation for rapid parameter configuration
• Continuous power adjustment (40–100% in 1% steps) ensures reproducible energy delivery across cleaning cycles
• Extended timer range (1–199 minutes) supports both rapid decontamination and extended soak protocols
• Sound-dampening lid reduces ambient noise levels to ≤55 dB(A) at 1 m distance, meeting ISO 15710 occupational safety guidelines
• AISI 304 stainless steel tank construction provides corrosion resistance against aqueous solvents, mild alkaline detergents, and low-concentration acidic rinses
• Power failure memory retains last-used settings—including time, power level, and display mode—eliminating reconfiguration after interruption
• Manual drain and fill valves enable controlled solvent exchange without disassembly or external pumping systems

Sample Compatibility & Compliance

The SK-Series accommodates a broad spectrum of labware geometries and materials, including borosilicate glass, fused silica, anodized aluminum fixtures, PTFE-coated tools, and ceramic crucibles. Its non-thermal, low-cavitation-threshold operation avoids thermal stress cracking in temperature-sensitive optics or polymer-based microplates. Units comply with IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for electrical equipment used in laboratory environments). While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, the design supports integration into validated cleaning SOPs under ISO 15883-1 for non-critical device reprocessing. All models meet CE marking requirements for the European Economic Area.

Software & Data Management

These units operate as standalone instruments with no embedded PC connectivity or proprietary software suite. Parameter settings are stored locally in non-volatile memory and recalled automatically upon power-up. The absence of USB/Ethernet interfaces eliminates cybersecurity vulnerabilities associated with networked lab instrumentation while simplifying audit trail management: all operational parameters (start time, duration, power setting, and elapsed cycle count) are visible on the LCD during active operation and remain accessible post-cycle for manual logbook entry. For laboratories implementing electronic lab notebooks (ELN), the consistent, human-readable display format facilitates structured data capture and traceability in accordance with ALCOA+ principles.

Applications

• Routine cleaning of HPLC vials, autosampler needles, and column frits prior to chromatographic analysis
• Removal of organic residue and biofilm from reusable cell culture inserts and transwell membranes
• Preparation of TEM grids and SEM stubs by particle-free surface conditioning
• Decontamination of reusable PCR plates and qPCR seal mats between runs
• Cleaning of precision weighing boats, calibration weights, and volumetric flasks to minimize mass measurement drift
• Supporting ASTM D2240 (Shore A hardness testing) sample preparation where surface contamination must be eliminated without altering polymer morphology

FAQ

Does this unit include a heater or temperature control capability?
No. The SK-Series provides real-time ambient liquid temperature monitoring only; it does not incorporate heating elements or thermostatic regulation.
Can the ultrasonic frequency be changed or selected?
No. All models operate exclusively at 53 kHz, a fixed frequency optimized for general-purpose laboratory cleaning with balanced penetration depth and cavitation intensity.
Is the tank volume calibrated to Class A volumetric standards?
No. Tank capacities (3–22.5 L) are nominal internal dimensions; they are not certified for volumetric accuracy per ISO 4787 or ASTM E542.
What maintenance is required for long-term reliability?
Routine inspection of the stainless steel tank for pitting or weld integrity, periodic cleaning of the transducer mounting surface with isopropyl alcohol, and verification of lid seal compression are recommended every 6 months or after 500 operating hours.
Are replacement tanks or custom-sized accessories available?
KUDOS offers OEM-compatible replacement tanks and sound-dampening lids for all SK-Series models; custom tank geometries are not supported under standard warranty terms.
