KQ-800KDB Desktop High-Power Digital Ultrasonic Cleaner

Overview

The KQ-800KDB Desktop High-Power Digital Ultrasonic Cleaner is an integrated benchtop system engineered for consistent, high-intensity ultrasonic cleaning in academic laboratories, R&D facilities, and quality control environments. It operates on the principle of piezoelectric transduction at a fixed frequency of 40 kHz, generating cavitation bubbles in aqueous or mild solvent-based cleaning media. These transient microbubbles collapse asymmetrically near solid surfaces—releasing localized energy sufficient to dislodge particulate contaminants, organic residues, biofilms, and entrapped air from complex geometries such as pipette tips, optical components, microfluidic chips, and precision mechanical parts. Unlike immersion-only cleaners with passive heating, the KQ-800KDB integrates digitally controlled thermostatic heating (20–80 °C) and programmable ultrasonic duty cycles, enabling reproducible cleaning protocols aligned with ASTM D2297 (adhesive surface preparation), ISO 13485 (medical device component cleaning validation), and USP (cleaning verification for pharmaceutical equipment).

Key Features

• Integrated digital control panel with independent real-time display of set/actual temperature, elapsed ultrasonic time, and timer countdown
• 800 W total ultrasonic power delivered via eight high-efficiency piezoelectric transducers (100 W per transducer), uniformly bonded to the bottom of the 304 stainless steel tank
• 1000 W adjustable heating element with ±1 °C thermal stability across the full 20–80 °C range, supporting temperature-dependent cleaning chemistries (e.g., alkaline degreasers, enzymatic solutions)
• Programmable timer (1–480 minutes) with automatic shutdown and audible end-of-cycle alert
• Over-temperature, over-voltage, and over-current protection circuits with LED fault indicators for operational safety and instrument longevity
• Drain valve positioned at the lowest point of the tank for complete fluid evacuation—critical for residue-free rinsing and multi-step cleaning workflows
• Corrosion-resistant 304 stainless steel tank and argon-welded stainless steel mesh basket, designed for mechanical durability and compatibility with neutral pH and mildly acidic/basic cleaning agents

Sample Compatibility & Compliance

The KQ-800KDB accommodates a wide range of sample types—including glassware (vials, cuvettes, chromatography columns), metal components (surgical instruments, calibration standards), ceramics (substrates, filters), and polymer-based labware (PCR plates, microcentrifuge tubes)—provided they are rated for immersion in heated aqueous solutions. Its 22.5 L tank volume supports batch processing of up to 30 standard 50 mL centrifuge tubes or six 100 mm Petri dishes simultaneously. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for laboratory electrical equipment). While not certified for Class II biological safety or autoclave sterilization, it serves as a validated pre-sterilization cleaning step in GLP/GMP-aligned workflows when paired with documented cleaning SOPs and periodic performance qualification (PQ) per ISO 13485 Annex A.

Software & Data Management

The KQ-800KDB operates via embedded firmware without external PC dependency; however, its digital interface supports audit-ready parameter logging through manual recording of cycle settings (time, temperature, power mode) in laboratory notebooks or electronic lab notebooks (ELNs). Though it lacks USB/Ethernet connectivity or FDA 21 CFR Part 11-compliant electronic signatures, its deterministic timer and thermal regulation enable repeatable process execution—essential for IQ/OQ/PQ documentation during equipment commissioning. Users may integrate the cleaner into broader validation frameworks by correlating ultrasonic intensity (via aluminum foil erosion test per ASTM E1754) and thermal uniformity (using calibrated NIST-traceable thermocouples) with cleaning efficacy metrics (e.g., residual protein assay per USP ).

Applications

• Removal of polishing compounds and machining oils from precision optics and metrology standards
• Deproteinization of electrophoresis tanks, gel trays, and blotting apparatus prior to reuse
• Deagglomeration of nanoparticle suspensions and colloidal dispersions for DLS or TEM sample prep
• Extraction of intracellular metabolites from cultured cells using chilled buffer sonication (with external cooling bath)
• Cleaning of HPLC injector valves, autosampler vials, and LC-MS ion source components to reduce carryover and baseline noise
• Preparation of SEM/TEM specimens requiring particle-free substrate surfaces

FAQ

Is the KQ-800KDB suitable for cleaning delicate MEMS devices or semiconductor wafers?
Yes—when operated at reduced time (≤5 min) and lower temperatures (25–40 °C) with deionized water or low-surface-tension solvents, it provides gentle yet effective particle removal without mechanical abrasion.
Does the unit include a degassing function?
While not labeled as “degas mode,” the 40 kHz frequency and high-power output effectively remove dissolved gases from cleaning solutions within 2–3 minutes of startup—improving cavitation efficiency for subsequent cleaning steps.
Can the stainless steel basket be replaced with custom fixtures?
Yes—the open-tank design and standardized 500×300 mm footprint allow integration of user-fabricated jigs, racks, or Teflon-coated carriers compatible with 304 SS dimensions and weight limits (max. 8 kg loaded).
What maintenance is required to sustain ultrasonic performance?
Monthly inspection of transducer bonding integrity, quarterly descaling of the heater element using 5% citric acid solution, and annual verification of timer accuracy and thermal sensor calibration using traceable references.
Is technical support available outside mainland China?
Yes—authorized distributors provide English-language operation manuals, application notes, and remote troubleshooting assistance; hardware service is coordinated through regional service centers with certified field engineers.
