SHUMEI KQ-1500DE Digital Ultrasonic Cleaner

Overview

The SHUMEI KQ-1500DE Digital Ultrasonic Cleaner is a high-capacity, microprocessor-controlled cleaning system engineered for reproducible, non-destructive removal of particulate contaminants, organic residues, and loosely adhered biofilms from laboratory glassware, precision components, medical instruments, and industrial parts. It operates on the principle of cavitation—generated by high-frequency (40 kHz) ultrasonic energy transmitted through an aqueous or solvent-based cleaning medium—producing microscopic implosions that dislodge surface-bound debris without mechanical abrasion. With a 112-liter stainless steel tank (700 × 400 × 400 mm internal), this unit supports batch processing of large or multiple items simultaneously, making it suitable for central lab facilities, QC/QA departments, and pre-sterilization preparation workflows in regulated environments.

Key Features

• Microcontroller-based digital interface with intuitive LED display for real-time monitoring and precise parameter control—including ultrasonic power (40–100% adjustable), heating temperature (ambient to 80 °C), and cycle duration (1–480 minutes).
• Robust 304 stainless steel tank construction ensures corrosion resistance, structural integrity, and compliance with long-term exposure to alkaline detergents, enzymatic solutions, and mild solvents.
• Integrated safety architecture includes automatic shutdown triggered by low liquid level, over-temperature, over-voltage, over-current, and dry-run conditions—fully documented via on-screen fault codes.
• Dual-function heating system (6000 W) enables rapid temperature ramping and stable thermal maintenance during extended cleaning cycles, supporting temperature-sensitive applications such as protein residue removal or enzymatic decontamination.
• Electrically actuated fill-and-drain system eliminates manual handling, reduces operator exposure to hot or chemically active solutions, and improves process repeatability across shifts.
• Acoustically insulated lid minimizes ambient noise emission (<75 dB(A) at 1 m) and suppresses heat loss, contributing to energy efficiency and workplace safety compliance.

Sample Compatibility & Compliance

The KQ-1500DE accommodates a broad range of sample geometries and materials, including borosilicate glassware (volumetric flasks, pipettes, filtration assemblies), stainless steel surgical tools, aluminum fixtures, ceramic substrates, and polymer-based components—provided they are compatible with aqueous cleaning chemistries and temperatures up to 80 °C. Its design aligns with general laboratory safety standards (IEC 61010-1) and supports adherence to institutional GLP protocols. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its digital logging capability (time-stamped parameter records) provides foundational traceability for internal audit requirements. Users implementing validated cleaning processes should perform IQ/OQ/PQ per ASTM F3127 and ISO 15883-1 guidelines.

Software & Data Management

The embedded control firmware retains user-defined presets (up to 10 programmable profiles), each storing ultrasonic intensity, temperature setpoint, dwell time, and auto-drain activation status. All operational parameters—including actual tank temperature, elapsed time, and power output—are continuously displayed and may be manually logged. Though the unit lacks Ethernet or USB export functionality, its deterministic behavior and repeatable digital inputs facilitate integration into broader lab informatics systems via external data acquisition modules or PLC interfacing (0–10 V analog outputs available upon request). Audit trails are maintained locally via non-volatile memory, preserving last-run settings and fault history even after power interruption.

Applications

• Pre-analytical sample preparation: cleaning HPLC vials, autosampler trays, and chromatography columns prior to use.
• Medical device reprocessing: adjunctive cleaning of reusable endoscopic accessories, dental handpieces, and orthopedic implants before autoclaving.
• Materials science: deburring, descaling, and flux removal from metal coupons, printed circuit boards, and MEMS devices.
• Pharmaceutical manufacturing: cleaning of stainless steel reactor components, filter housings, and filling line parts under cGMP-aligned cleaning validation protocols.
• Electronics manufacturing: residue removal from soldered PCBAs and semiconductor wafer carriers using low-surface-tension aqueous formulations.

FAQ

What is the recommended cleaning solution for optimal cavitation performance?
Aqueous alkaline or neutral pH detergents with low foaming characteristics and surfactant concentrations optimized for 40 kHz operation are preferred. Avoid high-foam or chlorinated solvents unless verified compatible with 304 stainless steel and sealed electronics.
Can the KQ-1500DE be used for sterilization?
No. This unit performs cleaning only—not sterilization. It may serve as a critical pre-sterilization step but must be followed by validated terminal sterilization (e.g., steam autoclaving, ethylene oxide, or hydrogen peroxide plasma) where sterility assurance is required.
Is the ultrasonic transducer array serviceable in-field?
Transducers are permanently bonded to the tank base and are not user-replaceable. Field service requires factory-authorized technicians and calibration verification post-repair.
Does the unit support remote monitoring or network connectivity?
Standard configuration includes no built-in communication ports. Optional analog signal outputs (0–10 V) for temperature and timer status can be integrated with building management or SCADA systems via third-party I/O modules.
What maintenance intervals are recommended for sustained performance?
Daily visual inspection of tank integrity and lid seal; monthly verification of liquid level sensor response and drain valve actuation; annual calibration of temperature sensor against NIST-traceable reference standard.
