Chu Ding KQ2200DA Digital Benchtop Ultrasonic Cleaner

Overview

The Chu Ding KQ2200DA Digital Benchtop Ultrasonic Cleaner is an entry-level, microprocessor-controlled cleaning system engineered for precision laboratory environments where consistent, non-abrasive removal of particulate contaminants, organic residues, and surface-adhered films is required. It operates on the principle of ultrasonic cavitation—generating high-frequency pressure waves (40 kHz) in aqueous or compatible solvent media to produce transient microbubbles that collapse near solid surfaces, delivering localized energy sufficient to dislodge sub-micron contaminants without mechanical contact. Designed as a compact, integrated unit with the ultrasonic generator and stainless steel tank housed in a single chassis, the KQ2200DA delivers reproducible cleaning performance across routine applications in analytical sample preparation, component pre-treatment prior to coating or metrology, and maintenance of glassware, pipette tips, and small instrumentation parts.

Key Features

• Digital microcontroller interface with real-time display of set and actual operating parameters—including timer countdown, power level, and safety status indicators.
• Adjustable ultrasonic power output (40–99% of nominal 100 W), enabling optimization for delicate substrates or heavily soiled samples.
• Stainless steel tank (SUS304 grade) formed via deep-drawn stamping for structural integrity, corrosion resistance, and long-term compatibility with common lab solvents including water, ethanol, isopropanol, and mild alkaline detergents.
• Integrated low-level liquid sensor that automatically halts ultrasonic operation when fluid volume falls below safe operational threshold—preventing transducer damage and ensuring compliance with equipment longevity best practices.
• Comprehensive electronic protection circuitry: monitors and interrupts operation upon detection of over-temperature, over-voltage, or over-current conditions—critical for unattended use in shared laboratory facilities.
• Built-in drain port with standard G1/4″ thread enables rapid, spill-free tank evacuation—supporting efficient workflow rotation between cleaning cycles and minimizing manual handling risks.
• Compact benchtop footprint (260 × 160 × 260 mm) and shallow depth design facilitate placement within fume hoods, under cabinets, or adjacent to analytical instruments without spatial conflict.

Sample Compatibility & Compliance

The KQ2200DA is validated for use with standard laboratory glassware (vials, cuvettes, syringes), metal components (sensors, calibration standards), ceramic substrates, and polymer-based tools—provided material compatibility with ultrasonic energy and chosen cleaning medium is confirmed. It does not incorporate heating or degassing functions; therefore, it aligns with ISO 13485 and GLP-aligned workflows requiring strictly temperature-stable cleaning conditions. While not certified to IEC 61000-6-3 (EMC) or UL 61010-1 out-of-the-box, its design conforms to baseline electrical safety expectations for Class I laboratory equipment operated in controlled indoor environments. No regulatory documentation (e.g., FDA 21 CFR Part 11, CE marking) is supplied with this model, and users must validate cleaning efficacy per internal SOPs or relevant ASTM D2607 (Standard Practice for Ultrasonic Cleaning of Metal Parts).

Software & Data Management

This model features a dedicated digital control panel with no external software dependency, USB connectivity, or data logging capability. All operational parameters—including elapsed time, power setting, and fault codes—are retained in volatile memory only during active use and are not stored post-shutdown. For laboratories requiring audit trails, electronic records, or integration into LIMS environments, supplementary hardware (e.g., programmable logic controllers or third-party serial-to-USB adapters with custom scripting) would be necessary. The absence of heating and variable frequency modulation simplifies validation protocols, reducing qualification burden in regulated QC/QA settings where parameter stability is prioritized over functional versatility.

Applications

• Pretreatment of HPLC vials, GC autosampler inserts, and spectrophotometric cuvettes to eliminate carryover and baseline noise.
• Cleaning of microfluidic chips, MEMS devices, and optical filters where mechanical scrubbing risks surface damage or particle generation.
• Removal of flux residues from printed circuit boards (PCBs) and soldered assemblies in electronics R&D labs.
• Preparation of electrodes, reference cells, and electrochemical sensors prior to calibration or electrochemical impedance spectroscopy (EIS).
• Routine decontamination of reusable pipette tips, tweezers, forceps, and watch glasses in teaching laboratories and quality control units.
• Supporting ASTM E1417 (Liquid Penetrant Testing) by ensuring flaw-indicating surfaces are free of interfering films prior to penetrant application.

FAQ

Does the KQ2200DA include a heater or temperature control function?

No. This model lacks heating elements and thermostatic regulation. It is intended for ambient-temperature ultrasonic cleaning only.
Can the unit operate continuously for extended durations?

Yes—within its 1–99 minute timer range—but continuous operation beyond 99 minutes requires manual reset. Duty cycle management is recommended to maintain transducer longevity.
Is the stainless steel tank electropolished or passivated?

The tank is fabricated from standard SUS304 stainless steel with a brushed finish. Electropolishing is not included; users requiring enhanced corrosion resistance should consider supplemental passivation or solvent selection.
What type of fuse or circuit protection is built in?

It incorporates a replaceable 250 V / 1 A slow-blow ceramic fuse compliant with IEC 60127-1, located internally behind the rear panel access cover.
Are replacement transducers or service manuals available directly from Chu Ding?

Original spare parts and technical documentation are distributed exclusively through authorized regional distributors—not via direct international sales channels.
