Shumei KQ-100DV Desktop Digital Ultrasonic Cleaner

Overview

The Shumei KQ-100DV is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, homogenization, solvent extraction, and cell disruption in laboratory, academic, and light industrial environments. It operates on the principle of cavitation—generated by high-frequency mechanical vibrations (40 kHz) transmitted through liquid media via piezoelectric transducers bonded to the stainless steel tank bottom. These vibrations produce transient microbubbles that collapse violently, releasing localized energy sufficient to dislodge sub-micron contaminants from complex geometries, porous surfaces, and delicate components without mechanical abrasion. Unlike analog units, the KQ-100DV integrates real-time digital feedback across all critical operational parameters—including ultrasonic power, solution temperature, water level, elapsed time, and cumulative runtime—enabling traceable, repeatable, and auditable cleaning protocols compliant with GLP-aligned workflows.

Key Features

• Microcontroller-based digital control system with dual-line LED display showing both setpoints and real-time measured values for ultrasonic power, temperature, water level, and timer.
• Adjustable ultrasonic output (40–100% of 100 W nominal power) to optimize energy delivery for sensitive samples or viscous solvents.
• Integrated heating module (400 W) with precise ±1 °C temperature regulation between 10–80 °C, supporting temperature-dependent cleaning and degassing applications.
• Stainless steel (304) inner tank (300 × 150 × 130 mm) formed by deep-drawn stamping for structural integrity and corrosion resistance; outer housing and sound-dampening lid also constructed from brushed stainless steel.
• Automated water-level sensing (1–90 mm range) with visual and audible low-level alerts, plus dry-run and over-temperature cut-off protection.
• Volatile solvent vapor recovery system integrated into the lid assembly, reducing ambient exposure and improving lab safety during use with organic solvents.
• Electrically actuated inlet/outlet valves for programmable fill-and-drain cycles—compatible with centralized lab water systems when configured with optional solenoid interfaces.
• Non-metallic polypropylene mesh basket included as standard, minimizing acoustic shadowing and ensuring uniform cavitation field distribution.

Sample Compatibility & Compliance

The KQ-100DV accommodates a broad spectrum of sample types—including glassware (vials, cuvettes, pipette tips), metal parts (surgical instruments, optical mounts), printed circuit boards, MEMS devices, and biological substrates (tissue culture plates, filtration membranes). Its sealed 304 stainless steel construction meets ISO 13485-relevant material compatibility requirements for medical device reprocessing validation. While not certified for sterile processing per ISO 17664 or AAMI ST79, it supports pre-sterilization cleaning steps aligned with ASTM F3127 (Standard Guide for Cleaning Validation of Medical Devices). The digital logging capability—particularly the 999,999-hour cumulative runtime counter—facilitates maintenance scheduling and satisfies internal QA documentation needs under ISO/IEC 17025 Clause 7.7 (Equipment Management).

Software & Data Management

The unit operates autonomously via embedded firmware; no external PC connection or proprietary software is required. All parameter settings—including power level, temperature setpoint, timer duration, and water level threshold—are retained in non-volatile memory after power cycling. The dual-display interface provides immediate verification of operational fidelity: left-side digits indicate user-defined values, right-side digits reflect live sensor readings (e.g., actual bath temperature vs. setpoint). This architecture eliminates reliance on external data loggers for basic process verification. For laboratories implementing 21 CFR Part 11 compliance, optional RS-232 or USB-to-serial adapters (sold separately) enable timestamped export of start/stop events and fault codes to validated third-party LIMS or ELN platforms.

Applications

• Removal of polishing compounds, flux residues, and particulate debris from precision optics and semiconductor wafers.
• Pre-analytical cleaning of HPLC vials, GC liners, and autosampler components to prevent carryover contamination.
• Accelerated solvent extraction of plant metabolites or environmental analytes from solid matrices.
• Disaggregation of protein aggregates and lipid vesicles prior to DLS or SEC analysis.
• Deaeration of degassed solvents used in electrochemical cell preparation or thin-film deposition.
• Routine decontamination of reusable labware in teaching labs and QC/QA facilities operating under ISO 9001 quality management systems.

FAQ

Is the KQ-100DV suitable for cleaning delicate MEMS sensors?

Yes—its 40 kHz frequency provides balanced cavitation intensity and penetration depth, and the adjustable power setting allows reduction to 40–60% for fragile microstructures.
Can the unit operate continuously for extended periods?

The cumulative timer supports up to 999,999 hours, and thermal management includes over-temperature cutoff; however, continuous operation beyond 24 h requires active cooling or duty-cycle modulation per manufacturer guidelines.
Does it support ultrasonic frequencies other than 40 kHz?

No—the KQ-100DV is fixed at 40 kHz; alternative models in the DV series offer 20 kHz, 25 kHz, or 28 kHz variants for specialized low-frequency applications.
What is the maximum allowable solvent volume for safe heating?

The 5.8 L capacity corresponds to the full inner tank volume; for optimal heat transfer and cavitation efficiency, maintain liquid levels between 30 mm and 80 mm (as indicated by the digital water-level readout).
Is the stainless steel tank passivated per ASTM A967?

The tank is fabricated from commercial-grade 304 stainless steel and electropolished post-forming; full ASTM A967 passivation is available as a custom order option.
