KUDOS SK3300HP Benchtop Adjustable-Power Ultrasonic Cleaner

Overview

The KUDOS SK3300HP is a benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, microplates, optical lenses, semiconductor wafers, and precision mechanical parts—where consistent cavitation energy delivery and process repeatability are critical. Operating at a fixed frequency of 53 kHz, the unit leverages piezoelectric transducer technology bonded to the bottom and side walls of a monolithic 304 stainless steel tank, generating uniform acoustic pressure fields optimized for mid-frequency cleaning efficacy: sufficient for dislodging micron-scale particulates and organic residues without inducing surface pitting or erosion on sensitive substrates. Unlike high-frequency (>100 kHz) units suited for sub-micron particle removal in microelectronics, or low-frequency (25–40 kHz) systems used for heavy-duty industrial degreasing, the 53 kHz design balances penetration depth, cavitation intensity, and bubble collapse stability—making it ideal for routine QC/QA labs, academic research facilities, and medical device reprocessing workflows requiring validated, non-destructive cleaning.

Key Features

• Digitally controlled power output adjustable from 40% to 100% of nominal 180 W in precise 1% increments—enabling method optimization across diverse sample matrices and contamination profiles.
• Backlit LCD interface with intuitive menu navigation displaying real-time timer countdown, selected power level (%), and tank temperature (ambient only; no integrated heater).
• Non-volatile memory retains last-used power and time settings following power interruption—supporting GLP-compliant procedural continuity.
• Monolithic 304 stainless steel tank (ASTM A240 compliant) with seamless welds and passivated interior surface—resistant to corrosion from aqueous detergents, mild alkaline solutions, and ethanol-based rinses.
• Compact footprint (330 × 180 × 290 mm) designed for integration into laminar flow hoods, fume cabinets, or shared benchtop environments without compromising accessibility or ventilation.
• Included stainless steel support rack ensures consistent sample immersion depth and prevents direct contact between parts and tank bottom—minimizing shadowing effects and promoting uniform energy distribution.

Sample Compatibility & Compliance

The SK3300HP accommodates standard laboratory vessels up to 300 mm in length, including beakers (up to 1000 mL), test tubes, cuvettes, and multi-well plates. Its 6 L tank volume supports batch processing while maintaining adequate liquid-to-part ratio for effective cavitation coupling. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity requirements) for laboratory electromagnetic environments. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its programmable parameters, audit-ready timer logs (via manual recording), and stable operational profile facilitate integration into GMP-aligned cleaning validation protocols when paired with documented SOPs and periodic performance qualification (PQ) testing per USP and ISO 15883-1.

Software & Data Management

The SK3300HP operates via embedded firmware with no external software dependency—ensuring reliability in air-gapped or regulated IT environments. All user inputs (timer value, power setpoint) are stored in EEPROM and recalled upon restart. Though the unit lacks USB/RS-232 connectivity or cloud synchronization, its deterministic behavior—combined with visible parameter confirmation on the LCD—supports traceable manual data entry into electronic lab notebooks (ELNs) or paper-based batch records. For laboratories implementing digital quality management systems (QMS), the device’s repeatable timing accuracy (±1 second over full range) and linear power scaling enable correlation of cleaning parameters with downstream analytical results (e.g., residual protein assay, particle count by light obscuration).

Applications

• Cleaning of HPLC and GC sample vials, syringe filters, and column hardware prior to solvent compatibility verification.
• Removal of solder flux residues and thin-film contaminants from PCB prototypes during R&D prototyping.
• Preparation of TEM grids and AFM cantilevers where hydrocarbon or particulate carryover must be minimized.
• Routine decontamination of reusable surgical instruments in university-affiliated teaching hospitals (non-sterile applications only).
• Supporting ASTM D2247 (humidity cabinet testing) sample preparation by eliminating fingerprint oils and handling residues from metal coupons.

FAQ

Does the SK3300HP include a heating function?
No. This model operates at ambient temperature only and does not incorporate a built-in heater. Temperature-sensitive samples or low-surface-tension solvents benefit from this design.
Is the ultrasonic frequency adjustable?
No. The transducer system is tuned to a fixed resonant frequency of 53 kHz, ensuring optimal energy transfer efficiency and long-term stability without frequency drift.
Can the unit be operated continuously beyond 199 minutes?
No. The maximum timer setting is 199 minutes. For extended cycles, users must manually reset the timer after completion—consistent with standard safety protocols for unattended ultrasonic operation.
What maintenance is required for long-term reliability?
Routine cleaning of the tank interior with mild detergent and periodic inspection of transducer mounting integrity are recommended. No scheduled calibration is required, though annual verification of timer accuracy and power linearity using a calibrated ultrasonic power meter is advised for regulated environments.
Is the stainless steel tank suitable for use with chlorinated solvents?
No. Type 304 stainless steel is not resistant to chloride-induced stress corrosion cracking. Avoid use with sodium hypochlorite, hydrochloric acid, or other chloride-containing solutions.
