Shumei KQ-2200B Benchtop Ultrasonic Cleaner

Overview

The Shumei KQ-2200B Benchtop Ultrasonic Cleaner is an integrated, compact laboratory-grade cleaning system engineered for precision and reliability in routine sample preparation workflows. It operates on the principle of ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in a liquid medium; their rapid collapse produces localized high-pressure shockwaves and microstreaming effects that effectively dislodge particulate contaminants, organic residues, and biofilms from surfaces without mechanical abrasion. Designed for laboratories with limited bench space, the KQ-2200B features a monolithic construction where the ultrasonic transducer assembly is directly bonded to the stainless steel tank, ensuring efficient energy transfer and long-term acoustic stability. Its fixed 100 W ultrasonic output delivers consistent cleaning performance across small-volume applications, while the built-in heating element (800 W) enables temperature-assisted cleaning protocols critical for dissolving waxes, lipids, or thermally labile deposits.

Key Features

• Integrated transducer design with direct tank bonding for optimal acoustic coupling and minimal energy loss
• Stainless steel tank (230 × 140 × 100 mm internal dimensions) and housing for corrosion resistance and structural integrity
• Precision digital timer with adjustable range from 1 to 20 minutes, supporting repeatable process standardization
• Independent temperature control system calibrated from ambient up to 80 °C, facilitating thermal enhancement of cleaning efficacy
• Included stainless steel mesh basket for secure placement and uniform exposure of delicate parts or glassware
• Manual drain valve located at the base of the tank for controlled solution removal and maintenance convenience
• Compact footprint (260 × 160 × 260 mm) optimized for shared lab benches or fume hood integration

Sample Compatibility & Compliance

The KQ-2200B is compatible with a broad spectrum of laboratory substrates—including glassware (vials, cuvettes, pipettes), metal tools (tweezers, forceps, surgical instruments), ceramic components, and polymer-based fixtures—provided they are not ultrasonically sensitive (e.g., certain coated optics or MEMS devices). While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its operational parameters align with common laboratory quality practices for non-sterile pre-cleaning steps defined in ASTM D2297 (Standard Practice for Cleaning Surfaces Prior to Adhesive Bonding) and ISO 15883-1 (Washer-disinfectors for heat-labile medical devices). Users performing GLP/GMP-regulated cleaning validation should document time, temperature, and bath composition per SOP, leveraging the unit’s stable thermal and temporal controls as foundational process variables.

Software & Data Management

The KQ-2200B operates via a dedicated front-panel interface with tactile push-button controls and LED indicators for timer status and heating activation. It does not incorporate embedded software, network connectivity, or data logging capabilities. All operational parameters—including elapsed time and set temperature—are displayed locally and require manual recording for audit trails. This analog-digital hybrid architecture ensures electromagnetic compatibility in environments with sensitive instrumentation (e.g., adjacent to HPLC systems or electron microscopes) and eliminates firmware-related cybersecurity risks. For labs requiring electronic record retention, integration with external environmental monitoring systems (via optional relay outputs or serial interfaces) may be implemented through third-party hardware adapters compliant with RS-232 or 0–10 V analog signaling standards.

Applications

• Routine cleaning of analytical glassware prior to spectroscopic or chromatographic analysis
• Removal of solder flux, grease, and machining oils from precision mechanical components
• Cell lysis and tissue homogenization support in molecular biology workflows (with appropriate buffer selection)
• De-gassing of solvents and reagent solutions prior to filtration or degassed HPLC mobile phase preparation
• Pre-treatment of electrodes, sensors, and microfluidic chips to eliminate surface adsorbates
• Supporting extraction protocols for botanicals, soils, or environmental samples using solvent-assisted sonication

FAQ

Is the ultrasonic power adjustable?
No—the KQ-2200B operates at a fixed ultrasonic output of 100 W, optimized for reproducible cleaning across its 3 L capacity.

Does this unit include a lid for noise reduction or vapor containment?
No—this model does not feature a sound-dampening cover or condensation-retaining lid. Acoustic output complies with IEC 61000-3-2 harmonic emission limits but requires adequate ventilation in enclosed spaces.

Can the heater and ultrasonics operate simultaneously?
Yes—both functions are independently controllable and may run concurrently to accelerate cleaning kinetics without compromising transducer longevity.

What maintenance is required for long-term reliability?
Routine inspection of the drain valve seal, periodic descaling of the tank interior using dilute acetic acid (especially when operating above 60 °C), and visual verification of transducer bond integrity every 6 months are recommended.

Is the stainless steel tank electropolished or passivated?
The tank is fabricated from standard grade 304 stainless steel with a brushed finish; electropolishing is not included as standard but can be specified for enhanced corrosion resistance in aggressive solvent environments.
