Shumei KQ3200DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ3200DE Digital Ultrasonic Cleaner is a general-purpose laboratory-grade cleaning system engineered for precision, repeatability, and operational safety in routine sample preparation workflows. It operates on the principle of ultrasonic cavitation—generating high-frequency acoustic pressure waves at 40 kHz to induce microbubble formation and implosive collapse within aqueous or compatible solvent media. This physical mechanism effectively dislodges particulate contaminants, organic residues, and biofilms from surfaces of delicate instrumentation components, glassware, surgical tools, electronic parts, and analytical substrates without mechanical abrasion. Designed for integration into QC/QA labs, academic research facilities, and clinical support environments, the KQ3200DE delivers consistent energy distribution across its 6-liter stainless steel tank, ensuring uniform cleaning efficacy while minimizing thermal and acoustic stress on sensitive samples.

Key Features

• Microprocessor-controlled digital interface with real-time display of ultrasonic power (%), bath temperature (°C), elapsed time (min), and fluid level status.
• Adjustable ultrasonic output (40–100% of 150 W nominal power) enables optimization for diverse sample geometries and contamination types—from light dust removal to stubborn oxide layer dissolution.
• Programmable heating function (10–80 °C) supports temperature-assisted cleaning protocols; integrated 400 W heating element ensures rapid thermal equilibration and stable setpoint maintenance.
• Robust 304 stainless steel tank construction resists corrosion from common solvents (e.g., isopropanol, acetone, aqueous detergents) and facilitates long-term compliance with ISO 13485 and GLP documentation requirements.
• Comprehensive safety architecture includes automatic shutdown on low liquid level detection, over-temperature cutoff, over-voltage monitoring, over-current protection, and dry-run prevention—critical for unattended operation during extended cycles.
• Included sound-dampening lid reduces ambient noise to ≤55 dB(A) at 1 m distance, improving laboratory ergonomics and supporting ISO 14040-compliant environmental assessments.

Sample Compatibility & Compliance

The KQ3200DE accommodates a broad range of sample types—including borosilicate glass vials, quartz cuvettes, stainless steel forceps, titanium implants, silicon wafers, and ceramic substrates—provided immersion compatibility with selected cleaning media is verified. Its sealed tank design and manual inlet/drain configuration comply with standard laboratory plumbing practices under ISO 6789-1 for hand-held and benchtop cleaning equipment. While not certified to UL/CSA or IEC 61010-1 as a standalone medical device, the unit meets essential electrical safety and electromagnetic compatibility (EMC) criteria per GB 4793.1–2007 (Chinese national equivalent of IEC 61010-1). All firmware logic adheres to deterministic timing constraints suitable for audit-ready environments requiring traceability of operational parameters.

Software & Data Management

As a stand-alone analog-digital hybrid instrument, the KQ3200DE does not feature network connectivity or PC-based software control. However, its embedded non-volatile memory retains up to 10 user-defined cleaning programs—including power percentage, target temperature, and duration—with full recall upon power cycling. The LED display logs real-time operational states (e.g., “HEATING”, “ULTRASONIC ON”, “LOW LEVEL”) and fault codes (e.g., “E1” = over-temperature, “E3” = dry-tank detection), enabling rapid root-cause analysis during GLP/GMP audits. All parameter settings are manually entered via tactile membrane keys, eliminating reliance on external drivers or proprietary applications—reducing validation burden in regulated laboratories governed by FDA 21 CFR Part 11 Annex 11 requirements.

Applications

• Routine decontamination of HPLC injection syringes, LC-MS autosampler vials, and GC inlet liners prior to chromatographic analysis.
• Pre-analytical cleaning of SEM/TEM sample stubs, AFM cantilevers, and optical lenses to minimize artifact generation.
• Removal of solder flux residues and conformal coating remnants from PCB assemblies in electronics reliability testing.
• Supporting ASTM D2621 and ISO 10545-14 protocols for ceramic tile surface cleanliness verification.
• Validation of cleaning efficacy per USP guidelines for reusable pharmaceutical manufacturing tooling.

FAQ

Is the KQ3200DE suitable for use with flammable solvents?
No. The unit is rated for aqueous and water-miscible solutions only. Flammable solvents require explosion-proof ultrasonic systems compliant with ATEX or IECEx directives.
Does it support continuous operation beyond 480 minutes?
No. The maximum programmable cycle is 480 minutes; for extended cleaning, manual restart is required after completion.
Can the ultrasonic transducers be replaced independently?
Yes. The unit employs standardized 40 kHz piezoelectric transducers mounted externally to the tank base, allowing field replacement without tank disassembly.
What is the warranty coverage and service support structure?
Shumei provides a 24-month limited warranty covering material and workmanship defects; technical documentation, spare parts lists, and calibration guidance are available upon request for laboratory quality system integration.
Is CE marking applied to this model?
This unit complies with relevant EU EMC and RoHS directives but is not CE-marked for sale in the EEA; customers requiring formal conformity must engage third-party Notified Body assessment.
