Kunshan KQ-3200DE / KQ-3200DA / KQ-3200DB / KQ-3200DV Benchtop Digital Ultrasonic Cleaner

Overview

The Kunshan KQ-3200 series comprises a family of benchtop digital ultrasonic cleaners engineered for precision cleaning, degassing, dispersion, emulsification, and cell disruption in academic, R&D, and quality control laboratory environments. These units operate on the principle of piezoelectric ultrasonics: high-frequency electrical signals (40 kHz) drive transducers bonded to the stainless steel tank bottom, generating controlled cavitation in the cleaning medium. This physical phenomenon produces transient microbubbles that collapse with localized energy release—enabling effective removal of particulates, organic residues, and surface contaminants from delicate substrates without mechanical abrasion. Designed for reproducible, operator-independent operation, each model integrates digital microcontroller logic with real-time monitoring of critical parameters including temperature, time, power delivery, and system safety status.

Key Features

• Digital microprocessor-based control system with non-volatile memory for retaining user-defined settings across power cycles
• Real-time digital display of set and actual bath temperature (range: ambient to 80 °C), ultrasonic duration (1–99 minutes), and cumulative operating hours (up to 999,999 h)
• Integrated low-level liquid detection and automatic shutdown to prevent transducer damage during dry operation
• Over-temperature, over-current, and over-voltage protection circuits compliant with IEC 61010-1 safety standards for laboratory equipment
• Stainless steel inner tank (SUS304 grade) and reinforced outer housing—models KQ-3200DE/DB/DA feature full stainless construction; KQ-3200DV includes optional manual drain valve
• Acoustically damped lid included on KQ-3200DE and KQ-3200DV models to reduce airborne noise emission and minimize solvent evaporation
• High-efficiency transducer array delivering uniform 40 kHz acoustic energy distribution; nominal output power of 100 W per unit (KQ-3200DE/DB/DA), scalable to 150 W in larger variants
• Precision-welded stainless steel mesh basket (included) optimized for sample retention while permitting unimpeded acoustic transmission

Sample Compatibility & Compliance

The KQ-3200 series accommodates a broad range of sample types—including glassware, metal parts, semiconductor wafers, optical components, surgical instruments, and biological tissue samples—provided they are compatible with aqueous or mild solvent-based cleaning media. The 40 kHz frequency balances cleaning efficacy with minimal risk of surface pitting on soft metals or etching on coated optics. All units meet CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the deterministic timer, temperature logging capability, and hardware-based safety interlocks support integration into GLP/GMP-aligned workflows when paired with validated SOPs and external audit trails.

Software & Data Management

These are standalone hardware-controlled instruments with no embedded PC interface or proprietary software suite. Parameter settings—including time, temperature, and power level—are stored in onboard EEPROM and recalled at startup. No data export functionality is provided; however, the cumulative hour counter and real-time digital displays facilitate manual logbook entries required under ISO/IEC 17025 Clause 7.7 (equipment usage tracking). For laboratories requiring electronic records, integration with external environmental monitoring systems is achievable via optional relay outputs (available on custom-configured units) or through periodic visual verification logged by authorized personnel.

Applications

• Routine cleaning of pipette tips, cuvettes, HPLC vials, and chromatography columns prior to analytical use
• Removal of flux residues and particulate contamination from PCB assemblies and microelectronic components
• Cell lysis and homogenization of cultured mammalian or bacterial cells in molecular biology workflows
• Extraction of metabolites or phytochemicals from plant tissues using solvent-assisted ultrasonication
• Degassing of solvents (e.g., HPLC-grade acetonitrile, water) to eliminate dissolved oxygen prior to chromatographic analysis
• Dispersion of nanoparticles and carbon nanotubes into stable colloidal suspensions for materials characterization
• Preparation of uniform thin-film coatings via ultrasonic-assisted spin-coating precursor solutions

FAQ

What is the difference between KQ-3200DE and KQ-3200DV models?

The KQ-3200DE features a 3 L tank (230×140×100 mm), 100 W output, acoustic lid, and stainless steel construction. The KQ-3200DV has an 8 L tank (300×150×180 mm), 150 W output, acoustic lid, manual drain valve, and larger footprint (410×260×380 mm).
Is this unit suitable for cleaning delicate optical lenses?

Yes—when used with low-surface-tension, non-corrosive cleaning solutions (e.g., 1% Alconox in deionized water) and operated at reduced time/duty cycle, it effectively removes fingerprints and dust without damaging anti-reflective coatings.
Does the device support continuous operation?

It is rated for intermittent duty cycles up to 99 minutes per session. Continuous unattended operation beyond manufacturer-recommended intervals may accelerate transducer fatigue and is not advised without thermal management validation.
Can the temperature be maintained precisely during extended sonication?

The unit provides proportional temperature control within ±2 °C of setpoint under static load conditions; accuracy may vary slightly under heavy cavitation load due to localized heating effects.
Are replacement transducers or tanks available as spare parts?

Yes—original-specification transducer modules and SUS304 inner tanks are supplied by authorized distributors under part numbers aligned with each model variant.
