KUDOS SK-Series Benchtop Ultrasonic Cleaner with Degassing Function

Overview

The KUDOS SK-Series benchtop ultrasonic cleaners are engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, filtration membranes, microfluidic chips, and precision metal parts—using controlled cavitation generated at a fixed frequency of 35 kHz. This low-frequency operation produces larger, more energetic cavitation bubbles compared to higher-frequency units (e.g., 80 kHz or 130 kHz), delivering enhanced mechanical scrubbing action ideal for removing particulate contaminants, dried residues, and loosely adhered organic films from macro-scale surfaces. Integrated degassing functionality operates prior to the cleaning cycle, reducing dissolved air content in the cleaning solvent (e.g., deionized water, isopropyl alcohol, or aqueous detergent solutions) to maximize cavitation efficiency and improve reproducibility across sequential runs. Designed as general-purpose instruments for routine QC labs, academic research facilities, and small-scale manufacturing environments, the SK-Series complies with fundamental electrical safety requirements per IEC 61010-1 and features a corrosion-resistant 304 stainless steel tank with rounded internal corners to minimize residue accumulation and simplify maintenance.

Key Features

• Stable 35 kHz ultrasonic transducer array delivering consistent energy distribution across the tank volume
• Degassing mode activated automatically before cleaning cycle initiation, reducing dissolved gas content to optimize cavitation density and cleaning uniformity
• Digital timer with 1–99 minute adjustable range and LED display for precise process control
• Sound-dampening hinged lid minimizing ambient noise exposure and preventing solvent evaporation during operation
• Manually operated drain valve and fill port enabling flexible solvent management without external plumbing
• Robust 304 stainless steel tank construction resistant to chemical degradation from common aqueous and mild organic solvents
• Front-panel power switch and timer controls with tactile feedback for glove-compatible operation

Sample Compatibility & Compliance

The SK-Series accommodates a wide range of sample geometries and materials, including borosilicate glass vials, stainless steel tools, aluminum fixtures, ceramic substrates, and polymer-based labware—provided they are not susceptible to ultrasonic erosion or stress cracking under sustained 35 kHz excitation. Units are suitable for use with water-based detergents (e.g., Alconox®, Liquinox®), ethanol, isopropanol, and acetone—subject to compatibility verification per solvent manufacturer guidelines. While not certified for ISO 13485 or FDA 21 CFR Part 11 compliance out-of-the-box, the absence of network connectivity or electronic audit trails renders them appropriate for non-GxP environments where manual logbook documentation satisfies internal quality procedures. Electrical certification aligns with GB 4793.1 (Chinese national adoption of IEC 61010-1) for laboratory equipment safety.

Software & Data Management

The SK-Series operates via embedded hardware logic with no external software dependency. All operational parameters—including timer setting, degassing activation, and power-on state—are managed through front-panel controls. No data logging, remote monitoring, or electronic recordkeeping capabilities are included. Users are expected to maintain manual logs (e.g., paper-based batch records or Excel spreadsheets) tracking date, operator ID, tank contents, duration, and visual inspection outcomes post-cleaning. This architecture supports laboratories operating under GLP or basic GMP frameworks where procedural consistency is verified through documented SOP execution rather than automated system validation.

Applications

• Routine cleaning of volumetric flasks, burettes, and graduated cylinders prior to calibration or titration
• Removal of protein residues from electrophoresis combs and gel casting trays
• Preparation of HPLC and GC sample vials to eliminate carryover contamination
• Cleaning of optical components (e.g., cuvettes, lens mounts) without abrasive contact
• Decontamination of reusable surgical instruments in teaching hospitals and veterinary clinics
• Supporting ASTM D2621 and ISO 14971 risk analysis workflows by ensuring consistent surface cleanliness prior to biocompatibility testing

FAQ

Is temperature control available on the SK-Series?
No. The SK-Series does not incorporate heating elements or temperature regulation. Cleaning must be performed at ambient liquid temperature.
Can the degassing function be disabled?
Yes. Degassing initiates automatically before each cleaning cycle but can be bypassed by initiating the timer immediately after filling—though this may reduce cleaning efficacy in aerated solvents.
What maintenance is required for long-term reliability?
Regular inspection of the tank seal integrity, periodic descaling using diluted citric acid (if hard water is used), and verification of transducer coupling integrity every 6 months are recommended.
Are replacement tanks or lids available as spare parts?
Yes. KUDOS supplies OEM-matched 304 stainless steel tanks and acoustic dampening lids for all SK-Series models under part numbers referenced in the service manual.
Does the unit meet CE marking requirements?
The SK-Series is manufactured to GB standards and carries CCC certification for the Chinese market. CE marking is not applied; users requiring EU conformity must conduct independent technical file assessment per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.
