Hechuang KH-600GKDV High-Power Temperature-Controlled Ultrasonic Cleaner

Overview

The Hechuang KH-600GKDV is a high-power, temperature-regulated ultrasonic cleaner engineered for demanding laboratory and industrial cleaning applications where reproducible cavitation intensity, thermal stability, and operational flexibility are critical. It operates on the principle of piezoelectric transduction at a fixed frequency of 40 kHz (with 25 kHz available as an optional configuration), generating controlled acoustic cavitation in liquid media to dislodge particulate contaminants, organic residues, and biofilms from complex geometries—including microfluidic devices, precision optics, surgical instruments, and semiconductor wafers. Its integrated heating and cooling modules enable precise thermal management across the full 0–80 °C range, supporting both low-temperature delicate part cleaning and elevated-temperature solvent-assisted degreasing. The unit features bottom-mounted transducers for uniform energy distribution and optimized tank resonance, minimizing standing wave interference and ensuring consistent cleaning efficacy throughout the 13 L stainless steel chamber.

Key Features

• 600 W adjustable ultrasonic output (10–100% stepless control) for scalable cleaning intensity without compromising transducer longevity
• Dual thermal regulation: 600 W heating element + 350 W active cooling system for rapid, stable temperature setpoint acquisition and maintenance
• 8-inch full-color LCD touchscreen with intuitive microprocessor-based menu navigation, supporting multi-step programmable cycles
• Acoustically optimized enclosure with sealed, vibration-damped chassis and stainless steel sound-dampening lid—measured noise emission <40 dB(A) at 1 m
• Automatic water fill and drain functionality with level-sensing valves, reducing manual intervention and improving workflow repeatability
• Argon-welded stainless steel mesh basket designed for mechanical durability, corrosion resistance, and unrestricted ultrasonic transmission
• Integrated degassing mode to remove dissolved air prior to cleaning—enhancing cavitation efficiency and reducing surface pitting risk on sensitive substrates

Sample Compatibility & Compliance

The KH-600GKDV accommodates a broad spectrum of sample types, including glassware, metal components, ceramic substrates, polymer-based microdevices, and reusable medical instruments. Its non-aggressive, aqueous-compatible cleaning mechanism aligns with ISO 15883-1 (washer-disinfectors), ASTM D2603 (ultrasonic cleaning validation), and FDA-recommended practices for pre-sterilization cleaning of reusable devices. While not certified to IEC 61010-1 or UL 61010-1 out-of-the-box, its electrical architecture complies with standard Class I safety requirements for laboratory equipment. Users performing GxP-regulated processes may configure audit trails via external logging software; the device supports time-stamped cycle records exportable in CSV format for GLP/GMP documentation.

Software & Data Management

The embedded firmware provides real-time monitoring of ultrasonic duty cycle, bath temperature, elapsed time, and power delivery status. All user-defined programs—including up to 10 stored cleaning protocols with independent settings for power%, temperature, duration, and degas sequence—are retained in non-volatile memory. Cycle logs capture start time, end time, setpoints, and fault codes (e.g., overtemperature, low-level detection). Data export is supported via USB interface; no proprietary software installation is required—raw log files open natively in spreadsheet applications. For integration into centralized lab information systems (LIMS), optional RS-232 or Ethernet modules can be added to enable SCPI command control and remote parameter synchronization.

Applications

• Pre-analytical preparation of HPLC vials, GC autosampler trays, and ICP-MS sample introduction components
• Cleaning of MEMS sensors, photomasks, and optical lenses requiring sub-micron particle removal without surface abrasion
• Removal of flux residues and solder paste from PCB assemblies prior to AOI inspection
• Decontamination of reusable laparoscopic tools and dental handpieces in central sterile supply departments (CSSD)
• Supporting ASTM E2877-22 (Standard Guide for Ultrasonic Cleaning Process Validation) through configurable, repeatable parameters
• Research-scale nanoparticle dispersion and sonochemical reaction initiation in controlled thermal environments

FAQ

Is the KH-600GKDV compliant with FDA 21 CFR Part 11 for electronic records?

No—the device does not include built-in electronic signature capability or audit trail encryption. However, exported CSV logs may be archived within a validated LIMS that meets Part 11 requirements.
Can the unit operate continuously for extended durations (e.g., >24 hours)?

Yes—thermal protection circuitry and duty-cycle monitoring prevent overheating; continuous operation is supported when ambient conditions remain within 15–30 °C and relative humidity ≤70%.
What cleaning solutions are compatible with the stainless steel tank?

Aqueous alkaline, neutral, and mild acidic formulations are suitable. Avoid halogenated solvents, strong oxidizers (e.g., undiluted HNO₃), and chlorinated cleaners, which may accelerate crevice corrosion.
Does the unit support external temperature probe input for bath calibration verification?

No—temperature sensing is internal only (PT100 sensor embedded in tank wall). For metrological traceability, users should perform periodic NIST-traceable thermometry using calibrated immersion probes.
Is the 25 kHz frequency option factory-installed or field-upgradable?

The 25 kHz configuration must be specified at time of order; transducer array tuning is hardware-specific and not retrofittable in the field.
