Shumei KQ2200E Benchtop Ultrasonic Cleaner

Overview

The Shumei KQ2200E is a benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, filters, sample vials, and small metal or ceramic parts—without mechanical abrasion. It operates on the principle of cavitation: high-frequency (40 kHz) acoustic energy transmitted through a liquid medium generates microscopic bubbles that rapidly collapse, producing localized shockwaves and microstreaming effects. This physical mechanism effectively dislodges particulate contaminants, organic residues, and loosely adhered biofilms from surfaces with high reproducibility and minimal risk of surface damage. Designed for routine use in QC laboratories, academic research facilities, and analytical preparation workflows, the KQ2200E delivers consistent performance under ambient or thermally assisted conditions (up to 80 °C), supporting both cold and warm ultrasonic cleaning protocols.

Key Features

• Stainless steel 304 construction throughout the tank, lid, and housing—ensuring corrosion resistance, structural integrity, and compliance with ISO 15190:2020 laboratory safety standards.
• Dual-function analog control panel enabling independent adjustment of heating temperature (ambient to 80 °C) and ultrasonic exposure time (1–60 minutes or continuous mode).
• Integrated sound-dampening lid significantly reduces operational noise levels—critical for shared lab environments where acoustic interference must be minimized per OSHA 29 CFR 1910.95 guidelines.
• High-efficiency transducer array delivering stable 100 W nominal ultrasonic output at 40 kHz, optimized for uniform energy distribution across the 3 L working volume.
• Manual inlet and drain system facilitates solvent exchange and waste handling without requiring permanent plumbing—ideal for labs using aqueous or low-toxicity organic cleaning solutions.
• 400 W heating element enables rapid thermal equilibration and supports temperature-dependent cleaning applications such as wax removal or protein denaturation prior to analysis.

Sample Compatibility & Compliance

The KQ2200E accommodates a broad range of sample formats: standard 10–50 mL volumetric flasks, HPLC vials, microscope slides, watch glasses, and small instrumentation components (e.g., LC injector needles, GC liners). Its stainless steel mesh basket and support tray prevent direct contact between samples and tank bottom, minimizing scratching risks. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not certified for sterile processing, it supports GLP-aligned cleaning validation when used with documented parameters (time, temperature, solution composition) and periodic verification of cavitation intensity via aluminum foil test per ASTM D2603-21.

Software & Data Management

As a mechanically controlled instrument, the KQ2200E does not incorporate digital firmware or data logging capabilities. All operational parameters are set manually and retained only during active use; no audit trail, user authentication, or electronic record generation is provided. Consequently, it is suitable for non-GxP environments or applications where procedural consistency is maintained through SOP documentation rather than automated traceability. For labs requiring 21 CFR Part 11-compliant operation, integration with external timers or environmental monitoring systems is recommended—but not supplied with the base unit.

Applications

• Routine decontamination of glassware prior to titration, spectrophotometry, or trace metal analysis.
• Removal of residual solvents, oils, or polishing compounds from precision-machined parts in materials science labs.
• Preparation of filtration membranes and syringe filters for pharmaceutical dissolution testing (USP <711>).
• Cleaning of electron microscopy grids and TEM specimen holders to eliminate hydrocarbon contamination.
• Supporting sample prep for ICP-MS and AAS by reducing blank contributions from particulate carryover.

FAQ

Is the KQ2200E suitable for cleaning delicate optical components?
Yes—when operated without heating and using low-surface-tension, non-ionic aqueous solutions, it safely cleans lenses, prisms, and fiber optic connectors without micro-scratching.
Can I use organic solvents like acetone or isopropanol in this unit?
No. The KQ2200E is rated exclusively for aqueous or water-miscible solutions. Flammable or chlorinated solvents pose fire and material compatibility hazards and void warranty.
Does the unit include a degassing function?
No. Degassing must be performed manually prior to initiating ultrasonic cycles, typically by running the unit empty for 5–10 minutes at elevated temperature.
What maintenance is required for long-term reliability?
Regular descaling with diluted citric acid (10% w/v) every 2–4 weeks prevents calcium carbonate buildup on transducers and tank walls—ensuring consistent ultrasonic transmission efficiency over time.
Is calibration or performance verification available?
Shumei provides no factory calibration certificate. Users should perform periodic aluminum foil erosion tests (per ASTM D2603) and temperature uniformity mapping to verify operational fidelity.
