Chu Ding KQ-5200 / KQ-5200B / KQ-5200E / KQ-5200V Benchtop Ultrasonic Cleaner

Overview

The Chu Ding KQ-5200 series benchtop ultrasonic cleaners are engineered for precision cleaning, degassing, dispersion, emulsification, and cell disruption in laboratory, academic, and light industrial environments. These units operate on the principle of high-frequency ultrasonic cavitation—generating microscopic vacuum bubbles in liquid media that rapidly collapse to produce localized shockwaves and intense shear forces. At a fixed frequency of 40 kHz, the transducers deliver consistent energy distribution across the tank volume, ensuring reproducible cleaning performance for delicate components such as optical lenses, microfluidic devices, HPLC columns, semiconductor wafers, and biological samples. The integrated generator-and-tank architecture minimizes signal loss and improves energy transfer efficiency compared to remote transducer configurations. All models comply with IEC 61000-6-3 (EMC emission standards) and meet basic electrical safety requirements per IEC 61010-1 for laboratory equipment.

Key Features

• Digitally controlled timer (1–20 minutes) with memory retention for repeatable process cycles
• Real-time digital display of set/actual temperature (on heating models), elapsed time, and operational status
• High-efficiency piezoelectric transducers rated at 100 W each, delivering uniform cavitation intensity across the tank bottom
• Electropolished SUS304 stainless steel tank—deep-drawn, leak-proof, and resistant to corrosion from aqueous and mild organic solvents
• Integrated safety circuitry: automatic shutdown triggered by over-temperature, over-voltage, or over-current conditions
• Removable, argon-welded stainless steel mesh basket for secure sample placement and easy retrieval
• Acoustic lid included on KQ-5200B, KQ-5200E, and KQ-5200V models to reduce noise emissions (<65 dB(A) at 1 m) and minimize solvent evaporation
• KQ-5200V variant features a sealed volatile solvent recovery system compliant with OSHA 1910.1200 and EU REACH Annex XVII requirements for handling low-boiling-point solvents (e.g., acetone, isopropanol, chloroform)

Sample Compatibility & Compliance

The KQ-5200 series accommodates a broad range of sample types—including glassware, metal parts, ceramic substrates, polymer films, and biological tissue specimens—without mechanical abrasion or thermal degradation. Cleaning efficacy is validated using ASTM D2617 (ultrasonic cleaning verification) and ISO 13485-aligned protocols for medical device pre-cleaning. The absence of moving parts and non-contact energy delivery ensures compatibility with fragile MEMS structures and coated optics. For regulated environments, the KQ-5200B/E/V models support GLP-compliant documentation when paired with external data loggers; while not natively 21 CFR Part 11 compliant, audit trails can be maintained via timestamped operator logs and printed parameter records. All units carry CE marking under the Low Voltage Directive (2014/35/EU) and RoHS 2011/65/EU conformity.

Software & Data Management

These are standalone hardware instruments with no embedded firmware-based software interface. Parameter settings are managed exclusively through front-panel membrane switches and LED/LCD indicators. No USB, Ethernet, or Bluetooth connectivity is provided. For laboratories requiring electronic recordkeeping, integration with external environmental monitoring systems (e.g., DeltaTrak, Testo Saveris) is achievable via analog 4–20 mA or 0–10 V output modules (optional accessory). Time-stamped operation logs must be manually entered into LIMS or ELN platforms. Firmware updates are not supported; calibration and functional verification follow manufacturer-recommended annual maintenance schedules.

Applications

• Pre-analytical cleaning of GC/HPLC vials, syringes, and injection port components
• Removal of flux residues and particulate contaminants from PCB assemblies and SMT stencils
• Extraction of intracellular proteins and nucleic acids from cultured cells or tissue homogenates
• Deagglomeration of nanoparticle suspensions prior to DLS or TEM analysis
• Degassing of casting resins and bonding adhesives to eliminate voids in composite fabrication
• Routine sterilization support for reusable labware in QA/QC labs operating under ISO 17025 or CLIA guidelines
• Surface preparation of electrodes and sensors prior to electrochemical characterization

FAQ

What is the difference between the KQ-5200, KQ-5200B, KQ-5200E, and KQ-5200V models?

The base KQ-5200 lacks heating and drainage. The KQ-5200B adds a 400 W heater and adjustable temperature control (0–80 °C). The KQ-5200E includes both heating and a bottom-mounted drain valve for solvent recovery. The KQ-5200V extends tank depth (13 L capacity), incorporates full enclosure with condensate reflux, and integrates an active volatile solvent capture system.
Can this unit be used with flammable solvents?

Only the KQ-5200V model is designed for safe operation with Class I flammable liquids per NFPA 30. Its sealed chamber, explosion-proof thermostat, and condensate return path mitigate ignition risk. Standard models (KQ-5200/KQ-5200B/KQ-5200E) are intended for aqueous or non-flammable solvent use only.
Is the ultrasonic power adjustable?

No—output is fixed at 200 W total (two 100 W transducers). Intensity modulation is achieved indirectly via duty cycling using the programmable timer.
What maintenance is required?

Daily: Drain and wipe tank interior; inspect mesh basket for deformation. Quarterly: Clean transducer surfaces with isopropyl alcohol; verify lid seal integrity. Annually: Calibrate temperature sensor (if equipped) and validate timer accuracy against a traceable stopwatch.
Does the unit include a warranty?

Chu Ding provides a standard 12-month limited warranty covering material and workmanship defects, excluding consumables (e.g., mesh baskets) and damage from improper solvent use or voltage irregularities.
