KUDOS SK7200HP Benchtop Ultrasonic Cleaner with Adjustable Power Output

Overview

The KUDOS SK7200HP is a precision-engineered benchtop ultrasonic cleaner designed for routine and critical cleaning tasks in analytical laboratories, quality control environments, and research facilities. It operates on the principle of high-frequency acoustic cavitation—generating microscopic vacuum bubbles in the cleaning solution that collapse violently upon contact with submerged surfaces, dislodging particulate contaminants, organic residues, and loosely adhered biofilms without mechanical abrasion. With a fixed operating frequency of 53 kHz—optimized for balanced cleaning efficacy and gentle treatment of delicate components—the SK7200HP delivers consistent energy distribution across its 15-liter tank volume. Its robust AISI 304 stainless-steel tank ensures long-term corrosion resistance against aqueous and mild solvent-based cleaning media, while the sealed transducer assembly maintains thermal and acoustic stability during extended operation cycles.

Key Features

• Backlit LCD interface with intuitive menu navigation and real-time display of timer countdown, power level (%), and internal tank temperature (non-heating mode)
• Fine-grained power modulation: continuous 1% incremental adjustment from 40% to 100% of nominal 350 W output—enabling method optimization for sensitive substrates such as optical lenses, microfluidic devices, or coated surgical instruments
• Digital timer with programmable range of 1 to 199 minutes, supporting repeatable process validation and integration into standardized SOP workflows
• Power interruption memory function: automatically resumes prior operational settings (timer value and power level) after brief power loss, minimizing procedural deviation
• Integrated drain valve and included flexible drain hose facilitate safe, spill-free solution exchange—critical for labs handling hazardous or regulated cleaning agents
• Compact footprint (390 × 330 × 310 mm) optimized for space-constrained fume hoods or shared instrument benches

Sample Compatibility & Compliance

The SK7200HP accommodates a wide range of sample geometries and material classes—including glassware (vials, cuvettes, pipette tips), metal components (calibration standards, tooling fixtures), ceramic substrates, and polymer-based labware—provided they are compatible with aqueous or low-volatility solvent baths. Its non-heating design eliminates thermal degradation risks for temperature-sensitive samples. While the unit itself does not incorporate active heating or degassing modules, it complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements) for laboratory electromagnetic environments. When deployed within GLP- or GMP-regulated workflows, users may document cleaning parameters—including timestamped power/timer settings—manually or via external logging systems to support audit readiness per ISO/IEC 17025 clause 7.7 and FDA 21 CFR Part 11 data integrity principles.

Software & Data Management

The SK7200HP operates as a standalone hardware platform with no embedded firmware update capability or network connectivity. All operational parameters are configured directly via the front-panel LCD interface. For traceability purposes, laboratories may integrate the device into broader digital quality management systems by recording run logs (e.g., date/time, operator ID, power %, duration, bath composition) in electronic lab notebooks (ELNs) or LIMS platforms. The absence of onboard data storage aligns with low-risk classification under EU MDR Annex VIII and avoids complex cybersecurity validation requirements typical of connected instrumentation.

Applications

• Pretreatment of HPLC vials and GC autosampler inserts to eliminate carryover contamination
• Cleaning of electron microscopy grids and TEM specimen holders prior to coating or imaging
• Decontamination of reusable pipette tips and filtration housings in molecular biology workflows
• Removal of polishing compounds and machining oils from precision metrology artifacts
• Preparation of surface-sensitive sensors and MEMS devices prior to functional testing
• Routine maintenance of optical components including spectrophotometer cells and interferometer mirrors

FAQ

Does the SK7200HP include a heater or temperature control function?

No. This model operates in ambient-temperature ultrasonic mode only; bath temperature rises passively due to acoustic energy dissipation but is not actively regulated.
Can the unit be used with flammable solvents?

Not recommended. The SK7200HP lacks explosion-proof certification and is intended for use with aqueous solutions or low-volatility, non-flammable cleaning agents only.
Is the 53 kHz frequency adjustable?

No. Frequency is fixed at 53 kHz to ensure stable cavitation field uniformity and transducer longevity.
What is the maximum recommended fill level for optimal performance?

For consistent acoustic coupling and uniform cleaning, maintain liquid level between 80–100% of tank depth—approximately 12–15 L in the 15 L tank.
How is calibration verification performed for this instrument?

Users may conduct periodic performance checks using standard aluminum foil erosion tests per ASTM D2603 or visual inspection of standardized test strips following established internal protocols.
