Chu Ding Technology KQ-3200DV Benchtop Digital Ultrasonic Cleaner

Overview

The Chu Ding Technology KQ-3200DV is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, homogenization, solvent extraction, and cell disruption in laboratory, academic, and light industrial environments. It operates on the principle of high-frequency ultrasonic cavitation—generating microscopic vacuum bubbles in liquid media that collapse violently upon reaching resonance, producing localized shockwaves and microstreaming effects. At a fixed frequency of 40 kHz, this transducer-driven system delivers consistent energy distribution across the entire 8-liter stainless steel tank volume (300 × 150 × 180 mm internal dimensions), enabling reproducible cleaning performance for delicate optics, microfluidic components, chromatography parts, surgical instruments, and biological samples. Its integrated digital control architecture ensures stable output under variable load conditions and supports repeatable protocol execution—a critical requirement for GLP-compliant sample preparation workflows.

Key Features

• Digital microcontroller-based interface with real-time display of set and actual temperature, elapsed time, cumulative operating hours (up to 999,999 h), and ultrasonic power level
• Precise temperature regulation from ambient to 80 °C with ±1 °C stability and automatic over-temperature cutoff
• Programmable timer (1–480 min) with auto-shutdown and memory retention for last-used parameters
• 150 W total ultrasonic output distributed across multiple piezoelectric transducers (50 W per transducer), mounted directly to the tank base for optimal energy coupling
• 304 stainless steel inner tank and structural housing—resistant to corrosion from aqueous, mild alkaline, and low-concentration organic solvents
• TIG-welded stainless steel mesh basket with ergonomic handle, designed to minimize shadowing and ensure uniform exposure of submerged samples
• Acoustic noise-reducing lid with sealing gasket to suppress airborne sound emission and reduce solvent evaporation
• Manual drain valve located at the tank base for safe, spill-free solution disposal
• Comprehensive safety monitoring: low-fluid-level detection, over-voltage, over-current, and thermal fault protection with visual alarm indicators
• Non-volatile memory stores user-defined protocols—including time, temperature, and power settings—for rapid recall and standardized operation

Sample Compatibility & Compliance

The KQ-3200DV accommodates a broad range of sample types and geometries, including glassware (vials, cuvettes, pipette tips), metal components (sensors, filters, nozzles), polymer substrates (PDMS chips, membranes), and biological specimens (tissue sections, cultured cells in suspension). Its 40 kHz frequency is optimized for general-purpose cleaning without inducing excessive mechanical stress on fragile structures. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity requirements) for laboratory equipment. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its parameter logging, audit-trail-capable timer/temperature history, and hardware interlocks support integration into validated cleaning processes under ISO 15883-1 (washer-disinfectors) or ASTM D4729 (ultrasonic cleaning validation guidelines).

Software & Data Management

The KQ-3200DV operates via embedded firmware without external PC dependency. All operational data—including start/stop timestamps, temperature profiles, and cumulative runtime—are retained in onboard EEPROM and displayed on the front-panel LCD. No proprietary software or drivers are required; however, users may manually record session logs for internal quality documentation. The device supports traceability through its unique serial-number-based manufacturing date display and lifetime hour counter—features aligned with ISO/IEC 17025 clause 6.4.10 (equipment records) and EU GMP Annex 15 (qualification documentation). For regulated environments, optional external data loggers can be connected via analog output (0–5 V) for temperature and status signals.

Applications

• Routine cleaning of HPLC columns, GC injectors, and spectrophotometer cuvettes prior to calibration
• Removal of organic residues and particulate contaminants from semiconductor wafers and MEMS devices
• Cell lysis and nucleic acid extraction in molecular biology workflows
• Deagglomeration of nanoparticle suspensions and ceramic slurries
• Preparation of reference standards by quantitative dissolution of certified materials
• Supporting ASTM E1715 (ultrasonic cleaning verification) and USP (cleaning validation of pharmaceutical equipment)

FAQ

What is the recommended cleaning solution for the KQ-3200DV?
Aqueous alkaline detergents (e.g., Alconox-type formulations) are preferred for general labware. For heavy organic contamination, ethanol or isopropanol may be used—but avoid chlorinated solvents due to corrosion risk and potential transducer degradation.
Can the KQ-3200DV be used for sterilization?
No. This unit performs cleaning and surface decontamination only—not microbial sterilization. Autoclaving, dry heat, or chemical sterilants must be used for sterility assurance.
Is the drain valve compatible with standard laboratory waste collection systems?
Yes—the 8-mm outlet accepts standard silicone or PVC tubing (ID 6–8 mm) for gravity-fed drainage into secondary containment.
How often should the transducers be serviced or recalibrated?
Transducers require no routine calibration. However, periodic visual inspection for delamination or cracking—and verification of consistent cavitation activity using aluminum foil test—is advised every 6 months per ISO 13074.
Does the unit support continuous operation mode?
Yes. When the timer is set to “0”, the ultrasonic generator remains active until manually stopped or interrupted by a safety condition (e.g., low water level).
