KUDOS SK-Series High-Frequency Benchtop Ultrasonic Cleaner

Overview

The KUDOS SK-Series High-Frequency Benchtop Ultrasonic Cleaner is an engineered solution for routine and demanding laboratory cleaning, sample preparation, and process support tasks. Operating at a stable 53 kHz frequency, the system leverages high-intensity cavitation in aqueous or compatible solvent media to generate microscale implosions that dislodge particulate contaminants, organic residues, and biofilm from surfaces of immersed objects. This frequency balances penetration depth and localized energy density—making it particularly effective for precision components, glassware, surgical instruments, semiconductor wafers, and analytical sample vials. Unlike lower-frequency cleaners (e.g., 25–40 kHz), the 53 kHz output minimizes surface pitting on delicate substrates while maintaining sufficient energy for efficient particle removal and mass transfer enhancement. The unit is designed for benchtop deployment in QC labs, R&D facilities, and academic teaching laboratories where reproducibility, operational simplicity, and compliance with standard cleaning validation protocols are essential.

Key Features

• Benchtop form factor with compact footprint—optimized for space-constrained lab environments without compromising tank volume (2 L to 22.5 L variants available)
• Digital timer with backlit LCD display (1–99 minute range), enabling precise control over sonication duration for method consistency
• 304 stainless steel ultrasonic tank—resistant to corrosion, thermal cycling, and common cleaning solvents including aqueous alkaline, acidic, and mild organic formulations
• Integrated sound-dampening lid—reduces airborne noise emission during operation and minimizes solvent evaporation
• Fixed-frequency transducer array—engineered for long-term stability and uniform energy distribution across the tank bottom
• Manual fill-and-drain configuration—supports controlled solvent exchange and waste handling in accordance with institutional chemical hygiene plans
• No integrated heating or power modulation—ensures mechanical and electrical simplicity, reducing maintenance points and enhancing long-term reliability

Sample Compatibility & Compliance

The SK-Series accommodates a broad range of sample geometries and materials, including but not limited to: borosilicate glassware (vials, cuvettes, pipette tips), metal instrumentation (tweezers, forceps, probes), ceramic substrates, and polymer-based microfluidic devices. Its 53 kHz operating frequency avoids excessive erosion of soft metals (e.g., aluminum alloys) and brittle ceramics while delivering consistent cleaning performance. Though not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device supports GLP- and GMP-aligned workflows when integrated into documented cleaning SOPs—including use in ASTM F2799-22 (Standard Guide for Validation of Cleaning Processes for Reusable Medical Devices) and USP (Cleaning Validation). Users are advised to validate cleaning efficacy per application-specific acceptance criteria using residue testing (e.g., TOC, HPLC, or visual inspection under UV light).

Software & Data Management

The SK-Series operates as a standalone hardware platform with no embedded software, network interface, or data logging capability. All operational parameters—including timer setting and power activation—are managed via front-panel controls. This architecture eliminates cybersecurity risks associated with connected instrumentation and aligns with institutions enforcing strict IT infrastructure policies. For traceability, users may manually record run parameters (start time, duration, solvent type, load composition) in laboratory notebooks or electronic lab notebooks (ELNs) compliant with 21 CFR Part 11 when paired with appropriate audit-trail configurations. No firmware updates or driver installation is required.

Applications

• Routine cleaning of HPLC vials, GC autosampler trays, and ICP-MS sample introduction components
• Pre-analytical decontamination of filters, membranes, and filtration housings prior to gravimetric or microbial analysis
• Assisted dissolution and homogenization of powdered pharmaceutical actives in formulation development
• Ultrasonic degassing of mobile phase solvents and calibration standards prior to chromatographic analysis
• Extraction of metabolites or nucleic acids from biological matrices in preparatory workflows
• Surface activation and contaminant removal prior to thin-film deposition or surface characterization (XPS, AFM)

FAQ

Is temperature control available on the SK-Series?
No. The unit does not incorporate a heating element or thermostat. Ambient-temperature operation is standard; external water baths or heated immersion vessels may be used if thermal assistance is required.
Can the ultrasonic power be adjusted during operation?
No. Each model delivers fixed nominal power (50 W to 500 W depending on tank size and transducer configuration); no variable-power circuitry is included.
What solvent compatibility should be considered?
Aqueous solutions, ethanol, isopropanol, acetone, and mild alkaline or acidic detergents are suitable. Avoid halogenated solvents (e.g., chloroform, carbon tetrachloride) due to potential degradation of sealing materials and safety hazards under cavitation.
Does the unit meet international electrical safety standards?
The device complies with GB 4706.1–2005 (Chinese national standard equivalent to IEC 60335-1) and carries CCC certification. CE marking is not applicable as it is not intended for EU market distribution without additional conformity assessment.
How is cleaning uniformity ensured across larger tanks (e.g., SK5200H)?
Transducer placement follows empirical acoustic mapping to maximize standing-wave node distribution; users are advised to rotate or reposition loads mid-cycle for critical applications requiring full-surface exposure.
