Shumei KQ-700V Benchtop Ultrasonic Cleaner

Overview

The Shumei KQ-700V is a general-purpose benchtop ultrasonic cleaner engineered for consistent, repeatable cleaning performance in academic laboratories, quality control environments, and small-scale manufacturing support labs. It operates on the principle of acoustic cavitation: high-frequency sound waves (40 kHz) generated by piezoelectric transducers induce rapid formation and collapse of microscopic vapor bubbles within an aqueous or solvent-based cleaning bath. This implosive energy dislodges particulate contaminants, organic residues, and loosely adhered biofilms from surfaces of immersed components—including glassware, metal parts, surgical instruments, printed circuit boards, and precision optics—without mechanical abrasion or surface damage.

Key Features

• Robust 304 stainless steel tank (500 × 300 × 180 mm internal dimensions; 27 L capacity) with seamless welding and electropolished finish for corrosion resistance and long-term chemical compatibility.
• Dedicated PTC (Positive Temperature Coefficient) heating element delivering precise thermal control across 0–80 °C, enabling temperature-assisted cleaning protocols for waxy, viscous, or proteinaceous soils.
• Fixed-frequency 40 kHz ultrasonic generation system with 700 W total output power, distributed via standard 50 W transducers mounted to the tank base—optimized for broad-spectrum contaminant removal while maintaining low harmonic noise emission.
• Integrated automatic frequency sweeping circuitry ensures stable energy coupling across varying load conditions and bath composition changes, minimizing standing wave nodes and improving cleaning uniformity.
• Sound-dampening stainless steel lid reduces ambient noise to <65 dB(A) at 1 m distance and enhances thermal retention during heated operation.
• Mechanical timer with 1–20 minute adjustable interval and audible end-of-cycle alert supports unattended batch processing under defined SOPs.
• Manual fill-and-drain interface with quick-connect fittings allows safe, controlled fluid handling without reliance on plumbing infrastructure—ideal for shared lab spaces or mobile deployment.

Sample Compatibility & Compliance

The KQ-700V accommodates a wide range of sample geometries and materials, including but not limited to volumetric flasks, pipette tips, filter housings, calibration standards, microfluidic chips, and reusable analytical hardware. Its open-bath design permits direct immersion of non-encapsulated items up to 180 mm in depth. While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, the unit meets general electrical safety requirements under GB 4793.1–2019 (equivalent to IEC 61010-1) and supports GLP-aligned documentation when used with traceable calibration records and validated cleaning protocols. Temperature and time parameters are manually set and recorded externally; no built-in audit trail or electronic signature capability is provided.

Software & Data Management

This model features a fully mechanical control interface with no embedded firmware, network connectivity, or digital data logging. All operational parameters—temperature setpoint, timer duration, and power activation—are adjusted via tactile rotary dials and toggle switches. Users are responsible for maintaining manual logs of cleaning cycles, solution composition, and maintenance activities in accordance with institutional GLP or internal QA procedures. For integration into regulated workflows requiring electronic recordkeeping, external data acquisition systems (e.g., USB thermocouple loggers, programmable timers) may be deployed alongside the unit.

Applications

• Pre-analytical preparation of HPLC vials, GC autosampler inserts, and ICP-MS sample introduction components.
• Removal of polishing compounds and machining oils from metrology artifacts prior to dimensional inspection.
• Cleaning of reusable cell culture inserts, transwell membranes, and microcentrifuge tubes in life science research settings.
• Decontamination of optical filters, lens mounts, and photomask carriers in semiconductor R&D labs.
• Supporting ASTM D2240 (durometer calibration), ISO 14644-1 (cleanroom component prep), and USP ancillary equipment cleaning where non-sterile, residue-free surfaces are required.

FAQ

Is the ultrasonic frequency adjustable?
No—the KQ-700V operates exclusively at a fixed 40 kHz frequency. Multi-frequency variants (e.g., 20/25/28/33/40 kHz) are available as custom configurations under separate model numbers.
Can this unit be connected to a continuous water supply or drainage line?
No—it relies solely on manual fill and drain via integrated valves. Permanent plumbing integration is not supported.
Does the unit include temperature calibration certification?
No factory-issued calibration certificate is included. Users should perform periodic verification using NIST-traceable thermometers per their internal SOPs.
What is the maximum recommended operating temperature for aqueous solutions?
80 °C is the upper limit for water-based baths. For solvent-based media, consult material compatibility charts and observe flash point safety margins.
Is the stainless steel tank passivated?
Yes—the 304 stainless steel construction undergoes standard industrial passivation post-fabrication to enhance oxide layer stability and minimize metal ion leaching during prolonged use.
