Shumei KQ5200DE Benchtop Digital Ultrasonic Cleaner (10 L Capacity)

Overview

The Shumei KQ5200DE is a benchtop digital ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, optical elements, surgical instruments, electronic parts, and analytical sample vessels. It operates on the principle of high-frequency cavitation—generating microscopic vacuum bubbles in aqueous or compatible solvent media via piezoelectric transducers vibrating at 40 kHz. When these bubbles collapse under acoustic pressure, they produce localized shockwaves and micro-jets that dislodge particulate contaminants, biofilms, and organic residues without mechanical abrasion. Designed for routine use in QC labs, R&D facilities, and clinical support environments, the KQ5200DE delivers reproducible cleaning performance across diverse sample geometries and material compositions while maintaining compliance with fundamental laboratory safety and operational integrity requirements.

Key Features

• Digital microprocessor-based control system enabling precise, repeatable parameter setting and real-time monitoring of operational status
• Stainless steel tank constructed entirely from ASTM A240 Type 304 stainless steel—resistant to corrosion, thermal stress, and chemical degradation from common cleaning solvents
• Integrated safety interlocks including over-temperature cutoff, over-current protection, low-water-level detection, and dry-run prevention to safeguard both equipment and user
• Stepless ultrasonic power regulation (40–100%) ensures optimal energy delivery for sensitive substrates such as coated lenses, MEMS devices, or thin-film sensors
• Programmable heating function with ±1 °C stability over ambient to 80 °C range supports enhanced cleaning efficacy for waxy or viscous residue removal
• Auto-sweep frequency modulation minimizes standing wave formation and improves acoustic field uniformity across the tank volume
• Sound-dampening hinged lid reduces ambient noise emission to ≤65 dB(A) at 1 m distance, supporting ISO 14040-compliant lab acoustics

Sample Compatibility & Compliance

The KQ5200DE accommodates a wide range of sample types—including glassware (vials, cuvettes, pipettes), metal tools (tweezers, forceps), ceramic substrates, and polymer-based components—provided compatibility with aqueous or mild solvent-based cleaning solutions is verified. Its sealed transducer mounting and non-porous tank design prevent cross-contamination and facilitate decontamination validation per ISO 15883-1 for reprocessing medical devices. While not certified to FDA 21 CFR Part 11 or EU Annex 11 out-of-the-box, the unit’s deterministic operation, parameter logging capability (via optional RS232 interface), and audit-ready digital display support integration into GLP/GMP workflows when paired with documented SOPs and calibration protocols.

Software & Data Management

The KQ5200DE features an embedded digital controller with non-volatile memory for storing up to five user-defined cleaning programs. Each program retains settings for duration, power level, target temperature, and start delay. Real-time values—including actual bath temperature, elapsed time, active power output, and liquid level—are continuously displayed on a dual-line LED screen. Optional serial communication (RS232) enables remote parameter configuration and timestamped event logging (e.g., cycle start/end, fault triggers) for traceability in regulated environments. No proprietary software installation is required; data export is compatible with standard terminal emulators or custom LabVIEW/Python scripts.

Applications

• Routine cleaning of HPLC vials, GC autosampler syringes, and ICP-MS sample introduction components
• Preparation of TEM/SEM specimens requiring particle-free surfaces
• Removal of flux residues from PCB assemblies prior to solderability testing (IPC-J-STD-001)
• Decontamination of reusable surgical instruments in ISO 13485-certified facilities
• Surface preparation of quartz crystal microbalances (QCM) and electrochemical electrodes
• Supporting ASTM D2621 and ISO 14644-1 cleanroom component validation protocols

FAQ

What is the recommended cleaning solution for general laboratory use?
Aqueous alkaline detergents (e.g., Alconox® or Liquinox®) are preferred for most applications. Avoid halogenated solvents unless explicitly validated for compatibility with 304 stainless steel and transducer materials.
Can the unit be operated without heating?
Yes—the heater can be disabled independently while maintaining full ultrasonic functionality and timer control.
Is calibration of temperature or timer traceable to national standards?
The unit includes factory calibration certificates for temperature sensor and timer accuracy. Field recalibration requires external NIST-traceable reference sources and is supported by Shumei’s service documentation.
How often should the tank solution be replaced?
Solution replacement frequency depends on load and contamination type; typical practice is daily for high-throughput labs or after each batch when processing biological or oily residues.
Does the unit meet CE or UL safety certification requirements?
The KQ5200DE complies with GB 4793.1–2007 (Chinese equivalent of IEC 61010-1) for laboratory electrical equipment safety. CE marking is not affixed; users requiring CE-conformant operation must verify local import regulations and perform risk assessment per EN 61000-6-3/6-4.
