KUDOS SK3200LHC Dual-Frequency Benchtop Ultrasonic Cleaner

Overview

The KUDOS SK3200LHC is a dual-frequency benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, microfluidic devices, and analytical instrumentation parts. It operates on the principle of acoustic cavitation—generating controlled micro-bubbles in liquid media through high-frequency mechanical vibrations transmitted via piezoelectric transducers bonded to the stainless-steel tank base. The device supports two discrete ultrasonic frequencies—35 kHz and 53 kHz—enabling users to select optimal energy distribution for different contaminant types and substrate sensitivities. Lower frequency (35 kHz) delivers higher cavitation intensity suitable for robust particulate removal from metal, glass, or ceramic surfaces; higher frequency (53 kHz) produces finer, more uniformly distributed cavitation bubbles, ideal for gentle yet effective cleaning of microstructures, MEMS devices, and coated optics without surface erosion. Designed for ISO/IEC 17025-compliant laboratories, the SK3200LHC integrates into routine QC workflows where reproducibility, traceability, and process control are essential.

Key Features

• Dual-frequency operation (35 kHz / 53 kHz) with one-touch switching via backlit LCD interface
• 150 W nominal ultrasonic power output with continuous 40–100% adjustment in 1% increments for granular process optimization
• Digital timer with 1–199 minute range and automatic shutdown for unattended operation
• Real-time display of active frequency, power level, remaining time, and internal tank temperature (non-heating configuration)
• Power-loss memory function: retains last operational parameters after interruption and resumes on power restoration
• Corrosion-resistant AISI 304 stainless-steel tank (300 × 150 × 100 mm) with radiused corners for uniform energy distribution and easy cleaning
• Compact footprint (330 × 180 × 240 mm) optimized for fume hoods, laminar flow cabinets, and shared lab benches

Sample Compatibility & Compliance

The SK3200LHC accommodates a broad range of sample geometries and materials—including pipette tips, HPLC vials, crucibles, watch parts, semiconductor wafers, and surgical instruments—when used with compatible cleaning solvents (e.g., aqueous alkaline solutions, isopropanol, or ethanol). Its non-heating design eliminates thermal degradation risks for temperature-sensitive polymers, adhesives, or biological residues. While the unit itself does not incorporate heating or degassing modules, its stable frequency control and low harmonic distortion support compliance with ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricants) and ISO 13004 (Ultrasonic cleaning equipment—Performance testing). When integrated into GLP/GMP environments, the device’s parameter memory and digital logging capability (via optional RS232/USB interface) facilitate audit-ready documentation per FDA 21 CFR Part 11 requirements when paired with validated software platforms.

Software & Data Management

The SK3200LHC features an embedded microcontroller-based control system with no onboard data storage. However, it supports external serial communication (RS232 standard, optional USB adapter) for integration with laboratory information management systems (LIMS) or custom process monitoring applications. Users may log timestamped operational records—including frequency selection, power setpoint, duration, and start/stop events—for batch traceability and SOP adherence. Firmware updates are performed via secure vendor-provided utilities; all parameter changes are immediately reflected on the LCD and retained across cycles. No proprietary drivers or cloud dependencies are required—ensuring long-term compatibility with legacy Windows/Linux workstations.

Applications

• Cleaning of chromatography columns, syringe filters, and autosampler vials prior to HPLC/UHPLC analysis
• Removal of polishing compounds and organic residues from optical lenses, mirrors, and laser components
• Preparation of SEM/TEM samples by eliminating particulate contamination without mechanical abrasion
• Routine maintenance of precision weighing boats, volumetric flasks, and calibration standards
• Decontamination of reusable PPE components (e.g., face shields, goggle frames) in biosafety labs using validated disinfectant solutions
• Supporting ASTM E1245 (Standard Practice for Determining the Size Distribution of Particles in a Sample) through standardized ultrasonic dispersion protocols

FAQ

Does the SK3200LHC include a heater or temperature control?

No. This model is configured as a non-heating ultrasonic cleaner. Temperature monitoring is provided only for ambient reference—not for thermal regulation.
Is the tank depth sufficient for submerging standard 50 mL centrifuge tubes?

Yes. With a 100 mm tank height and recommended liquid fill level of 60–80 mm, vertically oriented 50 mL conical tubes can be fully immersed while maintaining ≥10 mm clearance from the transducer surface.
Can the unit operate continuously for extended durations?

The SK3200LHC is rated for intermittent duty cycles up to 199 minutes per session. For prolonged use (>4 hours/day), periodic 15-minute cooldown intervals are recommended to maintain transducer longevity and acoustic coupling stability.
What safety certifications does this model carry?

It complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. CE marking is applied under manufacturer self-declaration per applicable EU directives.
Is the stainless-steel tank electropolished or passivated?

The AISI 304 tank undergoes standard acid passivation post-fabrication to enhance corrosion resistance and minimize metallic ion leaching during solvent-based cleaning cycles. Electropolishing is available as a factory option upon request.
