SHUMEI KQ2200DV Benchtop Digital Ultrasonic Cleaner

Overview

The SHUMEI KQ2200DV is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, homogenization, solvent exchange, and cell disruption in laboratory, academic, and light industrial environments. It operates on the principle of piezoelectric transduction—converting high-frequency electrical signals (40 kHz) into mechanical vibrations transmitted through a liquid medium. These vibrations generate controlled cavitation bubbles whose implosive collapse delivers localized energy sufficient to dislodge particulate contaminants, remove organic residues, and disrupt biological structures without mechanical abrasion or thermal degradation. Unlike analog or basic timer-controlled units, the KQ2200DV integrates real-time digital feedback across multiple operational parameters—including actual and setpoint temperature, liquid level, power output, elapsed time, and cumulative runtime—enabling traceable, repeatable, and auditable cleaning protocols essential for GLP-compliant laboratories and quality-controlled R&D workflows.

Key Features

• Dual-function digital display showing simultaneous real-time values for ultrasonic power (%), solution temperature (°C), water level (mm), elapsed cleaning time (min), and cumulative instrument operating hours (up to 999,999 h)
• Precise microcontroller-based control system supporting programmable sequences: adjustable ultrasonic power (40–100%), heating setpoint (10–80 °C), and timer duration (1–480 min)
• Integrated vapor recovery system minimizing solvent loss and improving workplace safety during volatile solvent use (e.g., acetone, isopropanol, ethanol)
• Automated water-level sensing with dual protection logic: low-level shutdown and dry-run prevention to safeguard transducers and heater elements
• Stainless steel (AISI 304) inner tank formed via deep-drawn stamping—ensuring structural integrity, corrosion resistance, and cleanability per ISO 14644-1 Class 5 requirements
• Electronically actuated fill-and-drain valves with sealed solenoid control, enabling unattended batch processing and integration into semi-automated lab workflows
• Acoustically damped stainless steel lid with ergonomic latch mechanism—reducing airborne noise to ≤55 dB(A) at 1 m distance while maintaining consistent cavitation field uniformity

Sample Compatibility & Compliance

The KQ2200DV accommodates a wide range of sample formats including glassware (vials, cuvettes, pipette tips), metal components (surgical instruments, calibration standards), ceramic substrates, and polymer-based microfluidic devices. Its 4 L capacity and 230 × 140 × 130 mm tank geometry support immersion of standard 50 mL centrifuge tubes, 96-well plates (with optional rack), and small PCB assemblies. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge and fast transients). While not certified for medical device reprocessing under ISO 17664 or AAMI ST79, it meets general laboratory equipment safety requirements per IEC 61010-1 and is suitable for non-critical cleaning tasks aligned with CLSI GP26-A4 guidelines for pre-analytical sample preparation.

Software & Data Management

The KQ2200DV employs embedded firmware with non-volatile memory to retain user-defined parameters—including power level, temperature setpoint, timer value, and default liquid level—across power cycles. All operational events (start/stop, overtemperature alerts, low-water cutoffs, voltage fluctuations >±10%) are timestamped and logged internally. Though no external software interface or USB/Ethernet connectivity is provided, the cumulative hour counter and parameter memory support internal maintenance scheduling and audit-readiness under ISO/IEC 17025 Clause 6.4.2 (equipment management). For regulated environments requiring electronic records, the device may be operated within validated SOPs that document manual entry of settings and verification of displayed parameters prior to each run.

Applications

• Pre-analytical cleaning of HPLC vials, GC liners, and ICP-MS nebulizers to eliminate trace metal carryover
• Degassing of solvents prior to chromatography or spectroscopy to reduce baseline noise and bubble formation
• Removal of polishing compounds from optical lenses and semiconductor wafers prior to metrology
• Cell lysis and nucleic acid extraction in molecular biology workflows using aqueous or mild detergent buffers
• Debonding of adhesive residues from reusable lab fixtures and microtiter plate carriers
• Supporting ASTM D2621 (ultrasonic cleaning validation) and USP (cleaning process verification) test protocols

FAQ

Is the KQ2200DV suitable for cleaning delicate MEMS devices or quartz crystal microbalances?

Yes—when operated at reduced power (40–60%) and with degassed deionized water or low-surface-tension solvents, the 40 kHz frequency provides sufficient cavitation intensity for residue removal while minimizing risk of surface pitting or resonant damage.
Can the unit maintain stable temperature during extended 8-hour cleaning cycles?

The 200 W heater and PID-controlled feedback loop enable ±1.5 °C stability over 480-minute cycles at setpoints between 40–60 °C; ambient drafts or open-lid operation will degrade performance.
Does the vapor recovery system condense and return solvent to the tank?

No—it captures and redirects volatile vapors toward an external exhaust duct or activated carbon filter; condensate collection is not integrated.
What maintenance is required for long-term reliability?

Transducer inspection every 12 months, stainless steel tank passivation annually, and verification of water-level sensor calibration using calibrated depth gauges per manufacturer’s service bulletin SB-KQ2200-03.
Is the cumulative hour counter tamper-proof or password-protected?

The counter is write-protected in firmware and cannot be reset by users; only authorized service technicians with diagnostic mode access can perform zeroing during recalibration.
