Shumei KQ-5200DE Benchtop Digital Ultrasonic Cleaner

Overview

The Shumei KQ-5200DE is a benchtop digital 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 cavitation—generating high-frequency acoustic pressure waves (40 kHz) that induce microbubble formation and collapse within liquid media, delivering mechanical energy to dislodge particulate contaminants from surfaces at sub-micron scale. Its integrated transducer array delivers uniform energy distribution across the 10-liter stainless steel tank, supporting reproducible cleaning of delicate components such as optical lenses, semiconductor wafers, HPLC columns, surgical instruments, and biological sample holders. Designed for continuous-duty operation under controlled environmental conditions, the unit complies with fundamental safety architecture per IEC 61010-1 for laboratory electrical equipment and supports traceable usage logging essential for GLP-compliant workflows.

Key Features

• Microprocessor-controlled digital interface with real-time display of ultrasonic power (%), set/actual temperature (°C), elapsed time (min), and cumulative operational hours (up to 999,999 h)
• Adjustable ultrasonic output (40–100% of 200 W nominal), enabling optimization for sensitive substrates or heavily soiled parts
• Precise thermostatic control (ambient to 80 °C) powered by a 600 W heating element, with over-temperature, over-voltage, and over-current protection indicators
• Stainless steel inner tank (300 × 240 × 150 mm) and laser-welded stainless mesh basket for corrosion resistance and mechanical stability
• Low-level liquid detection system with visual alert to prevent dry-run damage to transducers
• Programmable timer (1–480 minutes) with auto-shutdown and memory retention for frequently used protocols
• Rugged enclosure constructed from brushed stainless steel (excluding select base models), ensuring long-term durability in shared lab environments

Sample Compatibility & Compliance

The KQ-5200DE accommodates a wide range of sample geometries—including glassware, metal fixtures, ceramic substrates, and polymer-based components—within its 10 L capacity. Its 40 kHz frequency provides an optimal balance between cleaning efficacy and surface gentleness, making it suitable for fragile optics, MEMS devices, and pre-analytical biospecimen carriers. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device supports audit-ready documentation through its built-in cumulative hour counter and parameter memory functions. When operated with validated cleaning solvents and documented SOPs, it meets baseline requirements for ASTM D2603 (ultrasonic cleaning performance evaluation) and ISO 15797 (textile cleaning validation frameworks). Routine calibration verification of temperature and timer accuracy is recommended per internal QA protocols.

Software & Data Management

This model operates via embedded firmware without external PC dependency. All operational parameters—including power level, temperature setpoint, timer duration, and real-time sensor feedback—are stored in non-volatile memory and retained after power cycling. The digital display logs actual vs. target values continuously during operation, allowing manual transcription into lab notebooks or LIMS-compatible spreadsheets. For facilities requiring electronic records, integration with third-party data acquisition systems is feasible via optional RS-232 or analog voltage output modules (sold separately). The cumulative runtime counter serves as a maintenance scheduling reference, aligning with preventive service intervals defined in institutional equipment management policies.

Applications

• Cleaning of chromatography vials, syringe filters, and autosampler components prior to HPLC/GC analysis
• Degassing of solvents and mobile phases to eliminate air bubbles affecting detector baseline stability
• Removal of organic residues from electron microscopy grids and TEM sample stubs
• Preparation of nanoparticle suspensions via ultrasonic dispersion and deagglomeration
• Supporting tissue homogenization and cell lysis in molecular biology workflows (when combined with appropriate lysis buffers)
• Post-manufacturing cleaning of precision machined parts in prototyping labs

FAQ

Is the KQ-5200DE compatible with flammable solvents?

No. This unit lacks explosion-proof certification and must only be used with aqueous or non-flammable solvent mixtures. Always consult SDS documentation before introducing any cleaning medium.
Does it include a lid for noise reduction?

No. The standard configuration does not include a sound-dampening cover. Acoustic shielding must be implemented externally if ambient noise levels require mitigation.
Can the heater and ultrasonics operate simultaneously?

Yes. Independent control allows concurrent heating and sonication, enabling temperature-assisted cleaning protocols such as hot alkaline descaling.
What maintenance is required for long-term reliability?

Transducer integrity should be verified quarterly via visual inspection and impedance testing; tank interior must be cleaned regularly to prevent mineral buildup; drain valve seals should be inspected annually.
Is calibration documentation provided with shipment?

Factory calibration certificates are not included by default but can be requested at time of order for an additional fee. On-site calibration services are available through authorized Shumei technical partners in APAC regions.
