Shumei KQ2200DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ2200DE Digital Ultrasonic Cleaner is a benchtop general-purpose cleaning system engineered for precision laboratory applications requiring consistent cavitation-based particle removal from delicate instrumentation, glassware, surgical tools, and microcomponents. It operates on the principle of high-frequency ultrasonic energy (40 kHz) transmitted through a liquid medium—typically aqueous or mild solvent-based cleaning solutions—to generate controlled micro-cavitation bubbles. Upon collapse, these bubbles produce localized shockwaves and micro-jets capable of dislodging sub-micron contaminants from complex geometries without mechanical abrasion. Designed for routine QC/QA labs, academic research facilities, and small-scale production environments, the KQ2200DE integrates digital process control with robust 304 stainless steel construction to ensure long-term stability, corrosion resistance, and compliance-ready operation.

Key Features

• Digital microcontroller-based interface enabling precise, repeatable programming of ultrasonic power (40–100% of 100 W nominal output), heating temperature (10–80 °C), and cleaning duration (1–99 minutes).
• Real-time dual-display monitoring of setpoint vs. actual values for temperature and ultrasonic activity—enhancing process traceability and reducing operator error.
• Integrated safety protections including over-temperature, over-voltage, and over-current detection with visual alarm indicators.
• High-efficiency transducer array optimized for uniform energy distribution across the 3 L tank volume (230 × 140 × 100 mm internal dimensions), minimizing dead zones and ensuring reproducible cleaning performance.
• Full 304 stainless steel tank and housing—resistant to chemical degradation from common alkaline, acidic, or enzymatic cleaning agents used in ISO 15883-compliant reprocessing workflows.
• Included acoustic damping lid reduces ambient noise levels during operation and minimizes solution evaporation during heated cycles.
• Manual inlet and drain valves facilitate controlled fluid exchange—compatible with deionized water, ethanol, isopropanol, or low-surface-tension detergents approved under ASTM D4169 or USP for medical device cleaning validation.

Sample Compatibility & Compliance

The KQ2200DE accommodates a wide range of sample types—including pipette tips, HPLC vials, optical lenses, watch components, printed circuit boards, and dental instruments—without risk of surface pitting or dimensional distortion when operated within validated parameters. Its temperature and time programmability supports standardized cleaning protocols aligned with ISO 13485 quality management systems and FDA-recommended practices for reusable device reprocessing. While not certified as a Class II medical device, its design adheres to key elements of IEC 61000-6-3 (EMC emissions) and IEC 61010-1 (safety requirements for laboratory equipment). Documentation packages—including factory calibration records and material certifications for 304 SS—can be provided upon request for GLP/GMP audit readiness.

Software & Data Management

As a standalone hardware platform, the KQ2200DE does not incorporate networked software or PC connectivity. However, its digital interface logs all user-defined parameters and displays real-time operational status—enabling manual entry into lab notebooks or electronic batch records (EBRs). The non-volatile memory retains last-used settings across power cycles, supporting SOP-driven workflows. For laboratories implementing 21 CFR Part 11 compliance, external data loggers may be interfaced via optional analog voltage outputs (available on custom-configured units) to capture time-stamped temperature and power profiles for audit trails.

Applications

• Routine cleaning of analytical glassware (volumetric flasks, cuvettes, syringes) prior to UV-Vis or ICP-MS analysis.
• Preparation of substrates for SEM/TEM sample mounting where particulate-free surfaces are critical.
• Removal of flux residues from SMT assemblies in electronics R&D labs.
• Decontamination of reusable surgical instruments in veterinary or teaching hospital settings.
• Supporting ASTM F3250-20 validation studies for ultrasonic cleaning efficacy in pharmaceutical component manufacturing.

FAQ

Is the ultrasonic frequency fixed at 40 kHz?
Yes—the transducer stack is resonantly tuned to 40 kHz, a widely adopted frequency balancing cavitation intensity and penetration depth for general laboratory cleaning tasks.
Can this unit be used with flammable solvents?
No—this model lacks explosion-proof certification and is intended for use only with aqueous or non-flammable cleaning solutions per IEC 60079 guidelines.
What is the maximum recommended load weight inside the tank?
For optimal cavitation efficiency and thermal uniformity, the total immersed mass should not exceed 1.2 kg to avoid damping effects and uneven energy distribution.
Does the unit include a degassing function?
No dedicated degas mode is implemented; however, initiating ultrasonic operation at reduced power (40–60%) for 2–3 minutes prior to full-power cleaning effectively removes dissolved air from fresh solution.
Is calibration documentation included with shipment?
A factory-issued verification report confirming temperature accuracy (±2 °C at 50 °C), timer repeatability (±1 s), and power output linearity is supplied standard with each unit.
