Chu Ding KQ-300E Benchtop Ultrasonic Cleaner

Overview

The Chu Ding KQ-300E is a benchtop ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in academic laboratories, quality control environments, and R&D facilities. It operates on the principle of high-frequency ultrasonic cavitation—where 40 kHz acoustic energy induces controlled microbubble formation and collapse within aqueous or compatible solvent media. This physical mechanism delivers non-abrasive, uniform energy distribution across submerged samples, enabling effective removal of particulate contaminants, organic residues, and adsorbed films from delicate components such as optical lenses, semiconductor wafers, precision tools, glassware, and laboratory instrumentation parts. Its integrated transducer design ensures stable output and minimal harmonic interference, supporting reproducible cleaning performance under routine operational conditions.

Key Features

• Benchtop configuration with compact footprint (320 × 264 × 340 mm) optimized for standard laboratory workbenches and fume hood integration.
• Stainless steel tank (300 × 240 × 150 mm internal dimensions) formed via deep-drawn stamping and argon-welded seams for corrosion resistance and structural integrity.
• Digital LED display with independent controls for timer (1–20 min), heating setpoint (10–80 °C), and real-time temperature monitoring.
• Integrated sound-dampening lid to reduce ambient noise levels and minimize solvent evaporation during operation.
• Over-temperature, over-voltage, and over-current protection circuits with visual fault indicators for enhanced operational safety and equipment longevity.
• Removable stainless steel mesh basket for secure sample placement and easy retrieval; compatible with standard labware including beakers, crucibles, and microcentrifuge tubes.
• Manual drain valve located at the tank base for controlled solution disposal—designed for compatibility with neutral pH aqueous cleaning solutions and mild detergent formulations.

Sample Compatibility & Compliance

The KQ-300E supports cleaning of a broad range of materials including metals (stainless steel, aluminum, titanium), glass, ceramics, and certain polymers (e.g., PTFE, polypropylene). It is not recommended for use with highly volatile solvents (e.g., acetone, hexane) unless operated in certified explosion-proof enclosures. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity requirements) for laboratory-grade electrical equipment. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its digital timer and temperature logging capability (via optional external data logger) support GLP/GMP-aligned documentation practices when deployed in regulated QC/QA workflows. All stainless steel wetted surfaces meet ASTM A240 Grade 304 specifications.

Software & Data Management

The KQ-300E operates via embedded microcontroller logic without proprietary software dependencies. All operational parameters—including elapsed time, set temperature, and active status—are displayed locally on the front-panel LED interface. No USB, Ethernet, or Bluetooth connectivity is provided; however, the device supports manual protocol documentation through standardized lab notebooks or LIMS-integrated SOPs. For audit readiness, users may pair the unit with third-party temperature data loggers (e.g., compliant with ISO/IEC 17025 traceability requirements) to capture time-stamped thermal profiles during critical cleaning cycles. The absence of network interfaces eliminates cybersecurity concerns associated with connected lab instruments.

Applications

• Cleaning of HPLC columns, syringe filters, and autosampler vials prior to chromatographic analysis.
• Preparation of electron microscopy specimens by removing surface hydrocarbons and particulates from TEM grids and SEM stubs.
• Degassing of casting resins, adhesives, and nanoparticle suspensions to eliminate entrapped air bubbles affecting homogeneity.
• Cell lysis support in molecular biology workflows—used in conjunction with enzymatic or chemical lysis buffers for efficient nucleic acid extraction.
• Maintenance of metrology tools, including calipers, micrometers, and coordinate measuring machine (CMM) probes, where residue-free surfaces are essential for measurement accuracy.
• Restoration of vintage optical components, watch parts, and jewelry without mechanical abrasion or surface etching.

FAQ

Is the ultrasonic power output adjustable?
No—the KQ-300E delivers a fixed 300 W nominal output across the entire 40 kHz transducer array. Power modulation is not supported.
Can this unit be used with flammable solvents?
Not without additional engineering controls. The device lacks explosion-proof certification and should only be operated with aqueous or low-volatility, non-flammable cleaning solutions in well-ventilated areas.
Does it include a heater with automatic temperature maintenance?
Yes—the built-in 800 W heating element maintains setpoint temperature within ±2 °C tolerance under typical load conditions, with PID-based regulation and thermal cut-off protection.
What is the expected service life of the transducers?
Under normal usage (≤4 h/day, deionized water or mild detergent), the piezoelectric transducers exhibit >5,000 hours of operational reliability before measurable output decay occurs.
Is the tank volume calibrated to ISO/IEC 17025 standards?
The 10 L capacity is a nominal geometric volume. For volumetrically critical applications, users should perform in-house calibration using certified volumetric flasks per ISO 1042 guidelines.
