Shumei KQ-700DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ-700DE Digital Ultrasonic Cleaner is a general-purpose laboratory-grade cleaning system engineered for precision, repeatability, and operational safety in routine sample preparation workflows. It operates on the principle of high-frequency ultrasonic cavitation—generating controlled micro-bubbles in aqueous or compatible solvent media at a nominal frequency of 40 kHz. These bubbles collapse asymmetrically near solid surfaces, producing localized shockwaves and micro-jets that effectively dislodge particulate contaminants, organic residues, biofilms, and loosely adhered oxides from substrates without mechanical abrasion. Designed for compatibility with glassware, metal components, surgical instruments, optical lenses, electronic PCBs, and analytical sample holders, the KQ-700DE delivers consistent cleaning performance across diverse material classes while minimizing surface damage risk. Its 22.5 L tank volume supports medium-to-large batch processing—ideal for QC labs, university research facilities, and small-scale manufacturing cleanrooms where throughput and regulatory traceability are critical.

Key Features

• Digital microcontroller-based operation with real-time parameter monitoring and memory retention for time, power, and temperature settings
• Full 304 stainless steel construction—including tank, housing, and accessories—for corrosion resistance and long-term durability under repeated thermal and chemical exposure
• Adjustable ultrasonic power output (40–100% of 700 W nominal) to optimize energy delivery for delicate vs. robust substrates
• Precise digital temperature control (10–80 °C) with integrated 800 W heating element and dual-sensor feedback loop for stable bath conditions
• Programmable timer (1–480 minutes) with automatic shutdown and audible end-of-cycle alert
• Comprehensive safety interlocks: low-level liquid detection, over-temperature cutoff, over-voltage/current protection, and dry-run prevention
• Inclusive accessory set: perforated stainless steel mesh basket, adjustable support rack, and acoustic-dampening lid to reduce ambient noise and evaporation
• Manual inlet and drain ports positioned for ergonomic access and compatibility with standard lab plumbing infrastructure

Sample Compatibility & Compliance

The KQ-700DE accommodates a broad range of sample geometries and materials, including volumetric flasks, centrifuge tubes, pipette tips, chromatography vials, semiconductor wafers, and reusable surgical tools. Its 40 kHz transducer configuration balances penetration depth and cleaning intensity—making it suitable for both macro-particulate removal and fine residue dissolution. The unit complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its stainless-steel wetted parts meet ASTM A240/A240M specifications for 304 grade. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its programmable parameters, digital audit trail (via display history), and hardware safeguards support alignment with GLP/GMP documentation requirements when integrated into validated cleaning protocols.

Software & Data Management

The KQ-700DE features an embedded digital interface—not PC-dependent software—with non-volatile memory for up to 10 user-defined cleaning programs. All active parameters (elapsed time, set temperature, actual bath temperature, power level, and remaining cycle duration) are continuously displayed on a high-contrast LED screen. No external drivers or proprietary applications are required; however, process logs can be manually recorded for SOP adherence. For laboratories requiring electronic recordkeeping, the unit’s deterministic behavior—repeatable power delivery, calibrated thermal response, and fixed frequency stability—enables integration into broader LIMS or MES platforms via manual entry or optional RS-232/USB data logging modules (sold separately).

Applications

• Pre-analytical cleaning of HPLC vials, GC autosampler trays, and ICP-MS sample introduction components
• Decontamination of reusable labware prior to sterilization or autoclaving
• Removal of flux residues from printed circuit boards in electronics R&D
• Surface preparation of metal coupons for corrosion testing per ASTM G1
• Cleaning of optical components (e.g., cuvettes, prisms) without scratching or coating degradation
• Supporting USP and environmental surface hygiene validation in pharmacy compounding suites
• Routine maintenance of filtration housings, syringe filters, and membrane supports

FAQ

Is the KQ-700DE suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at reduced power (40–60%) and lower temperatures (25–40 °C) with low-surface-tension, non-ionic detergents, it provides gentle yet effective contaminant removal without compromising micro-structural integrity.
Can this unit be used with solvents other than water?
It is compatible with aqueous solutions and select low-flashpoint solvents (e.g., isopropanol, ethanol) provided vapor containment and ventilation protocols are followed per OSHA and local fire codes. Flammable solvent use requires additional safety certification and is not covered under standard warranty.
Does the unit include calibration documentation or traceable certificates?
Factory calibration of temperature and timer functions is performed prior to shipment. NIST-traceable calibration certificates are available upon request at additional cost and require scheduled service intervention.
What maintenance is required for long-term reliability?
Routine inspection of transducer adhesion, periodic descaling of the tank using dilute citric acid solution, and verification of lid seal integrity every 6 months are recommended. No scheduled lubrication or firmware updates are necessary.
Is remote monitoring or Ethernet connectivity supported?
No—the KQ-700DE is a standalone instrument with local digital control only. For networked environments, third-party IoT gateways may be interfaced via analog voltage outputs (if equipped) or visual status capture via machine vision systems.
