Overview
The KUDOS SK3200H is a high-frequency benchtop ultrasonic cleaner engineered for precision cleaning, degassing, dispersion, emulsification, and extraction in analytical, quality control, and research laboratory environments. Operating at a fixed frequency of 53 kHz, the unit leverages piezoelectric transducer technology to generate controlled cavitation within aqueous or compatible solvent media. This frequency balances penetration depth and micro-cleaning efficacy—offering superior particle removal from intricate geometries (e.g., pipette tips, HPLC columns, optical lenses, and microfluidic components) without inducing excessive erosion on delicate substrates. Unlike lower-frequency cleaners (<40 kHz), the 53 kHz output minimizes macroscopic turbulence while maintaining sufficient energy density for sub-micron contaminant dislodgement. The device complies with IEC 61000-6-3 (EMC emissions) and IEC 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use), ensuring safe integration into GLP- and ISO/IEC 17025-compliant workflows.
Key Features
- Stable 53 kHz ultrasonic generation via high-efficiency ceramic transducers bonded to the tank base—optimized for reproducible cavitation intensity across repeated cycles.
- Digital timer with extended range (1–199 minutes), enabling precise process control for both short-duration surface decontamination and extended batch treatments.
- 4.5-liter stainless steel tank constructed from medical-grade 304 stainless steel (ASTM A240), resistant to corrosion from common cleaning agents including alkaline detergents, ethanol, and isopropanol.
- Benchtop footprint (330 × 180 × 240 mm) designed for compatibility with fume hoods, laminar flow cabinets, and shared lab benches—no external cooling or ventilation required.
- Integrated support rack included as standard, facilitating vertical sample suspension to maximize exposure to acoustic fields and prevent shadowing effects.
- Front-panel LED display with backlight ensures legibility under low-ambient lighting conditions typical in analytical laboratories.
Sample Compatibility & Compliance
The SK3200H is validated for use with glassware (vials, cuvettes, chromatography vials), metal tools (tweezers, forceps), ceramic substrates, and polymer components rated for ultrasonic exposure (e.g., PTFE, polypropylene). It is not recommended for soft metals (aluminum, brass), uncoated optical coatings, or biological tissue samples without prior validation. Cleaning protocols may be aligned with ASTM D2212 (standard practice for ultrasonic cleaning of metals) and ISO 15883-5 (washer-disinfectors — Part 5: Validation and routine control). While the unit itself does not carry FDA 510(k) clearance or CE marking for medical device reprocessing, its design supports documentation of cleaning validation per ISO 13485 and EU MDR Annex I requirements when integrated into validated SOPs.
Software & Data Management
The SK3200H operates as a standalone analog-digital hybrid system with no embedded firmware, network interface, or data logging capability. All operational parameters—including elapsed time and power activation—are manually set and visually confirmed via the front-panel display. This architecture eliminates cybersecurity risks associated with connected instruments and simplifies regulatory audit trails: user actions are directly traceable through lab notebook entries or electronic batch records. For labs requiring traceability, integration with external time-stamped video monitoring or programmable logic controllers (PLCs) is feasible via dry-contact relay outputs (optional accessory). No proprietary software installation or license management is required.
Applications
- Routine cleaning of HPLC autosampler vials, GC liners, and syringe filters prior to instrumental analysis.
- Removal of organic residues and particulates from semiconductor wafers, MEMS devices, and photomasks during R&D prototyping.
- Preparation of nanoparticle suspensions via sonication-assisted dispersion in aqueous or ethanolic media.
- Accelerated solvent extraction of plant metabolites or environmental analytes (e.g., PAHs, PCBs) from solid matrices.
- Degassing of mobile phase solvents prior to LC-MS operation to reduce baseline noise and pump cavitation.
- Surface activation of PDMS microfluidic chips prior to plasma bonding or protein immobilization.
FAQ
Is the SK3200H suitable for cleaning delicate optics or coated lenses?
Yes—when operated with low-surface-tension, non-abrasive solvents (e.g., IPA/water mixtures) and limited exposure times (≤5 min), it effectively removes fingerprint oils and dust without damaging anti-reflective or hydrophobic coatings.
Can the unit be used with flammable solvents?
No. The SK3200H lacks explosion-proof certification and should only be used with non-flammable or low-flashpoint solvents (flash point >60°C) in well-ventilated areas.
Does the timer retain settings after power interruption?
No—the timer resets to default upon power loss; manual reconfiguration is required before each cycle.
What maintenance is required for long-term reliability?
Monthly inspection of tank integrity, quarterly cleaning of transducer mounting surfaces with isopropyl alcohol, and annual verification of power output using calibrated calorimetric methods per ASTM E1538.
