Overview
The KQ-100KDB Desktop Digital Ultrasonic Cleaner is an entry-level, compact benchtop instrument engineered for precision cleaning, degassing, dispersion, emulsification, and cell lysis in academic laboratories, R&D facilities, and quality control environments. It operates on the principle of high-frequency ultrasonic cavitation—generating controlled micro-bubbles in liquid media via piezoelectric transducers bonded to the stainless steel tank bottom. At a fixed frequency of 40 kHz, these bubbles collapse violently near submerged surfaces, producing localized shockwaves and microstreaming that remove particulate contaminants, organic residues, and biofilms from delicate instruments, glassware, optical components, electronic parts, and biological samples without mechanical abrasion. Its integrated digital control system enables repeatable, traceable operation—critical for method standardization in GLP-compliant workflows.
Key Features
- Digitally programmable timer (1–99 minutes) with memory retention for frequently used cleaning cycles
- Independent digital temperature control (20–80 °C) with real-time display and over-temperature safety cutoff
- 100 W ultrasonic power output delivered by a single high-efficiency transducer—optimized for uniform energy distribution across the 2 L tank volume
- Electropolished 304 stainless steel inner tank (150 × 140 × 100 mm) formed via deep-drawing for corrosion resistance and acoustic coupling integrity
- Integrated protection circuitry: over-voltage, over-current, and over-temperature fault detection with LED status indicators
- Front-panel LCD interface with intuitive button navigation—no external software or PC required for basic operation
- Compact footprint (208 × 192 × 210 mm) suitable for fume hoods, laminar flow cabinets, and shared lab benches
Sample Compatibility & Compliance
The KQ-100KDB accommodates a wide range of sample formats including pipette tips, microcentrifuge tubes, watch glasses, crucibles, semiconductor wafers, microscope slides, and small surgical tools. Its non-aggressive cleaning mechanism preserves surface integrity of soft metals (e.g., aluminum, copper), coated optics, and polymer-based substrates. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device supports documentation-driven validation protocols—its stable frequency, calibrated temperature control, and deterministic timer enable IQ/OQ execution per ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricating Oils) and ISO 11578 (Ultrasonics — Characteristics of Ultrasonic Cleaning Equipment). Users performing cleaning validation under GMP or ISO/IEC 17025 must implement supplementary calibration records for time, temperature, and power output.
Software & Data Management
The KQ-100KDB operates as a standalone unit with no embedded data logging or USB/Ethernet connectivity. All operational parameters—including set time, actual elapsed time, target and measured temperature—are displayed in real time on the front-panel LCD but are not stored or exportable. For regulated environments requiring audit trails, integration with external environmental monitoring systems (e.g., Vaisala viewLinc, DeltaTrak) via optional analog voltage outputs (0–5 V DC) is feasible using third-party signal conditioning modules. The absence of network interfaces inherently limits cybersecurity exposure—a design consideration aligned with NIH and EU laboratory cybersecurity guidance for non-networked instrumentation.
Applications
- Routine cleaning of HPLC vials, GC autosampler trays, and ICP-MS nebulizer components prior to trace-metal analysis
- Removal of solder flux residues from PCB assemblies in electronics prototyping labs
- Preparation of nanoparticle suspensions via ultrasonic dispersion in aqueous or organic solvents
- Accelerated solvent extraction (ASE) of plant metabolites from ground botanical tissue
- Disaggregation of bacterial biofilms from titanium implant surfaces for antimicrobial efficacy testing
- Degassing of low-viscosity resins prior to photolithography or 3D printing
- Cell disruption for intracellular protein extraction in microbiology teaching labs (with appropriate lysis buffer optimization)
FAQ
What is the recommended cleaning solution for the KQ-100KDB?
Aqueous alkaline detergents (e.g., Alconox® Liquinox®) or ethanol/water mixtures are preferred for general labware. Avoid chlorinated solvents, strong acids, or undiluted acetone—these may degrade seals or compromise transducer adhesion.
Can the KQ-100KDB be used for sterilization?
No. Ultrasonic cleaning removes bioburden but does not achieve sterility. It is a pre-sterilization step only; autoclaving, dry heat, or ethylene oxide remains required for terminal sterilization.
Is the stainless steel tank electropolished?
Yes—the inner tank surface undergoes electropolishing to reduce micro-roughness, minimize particle entrapment, and enhance cleanability per USP environmental control standards.
Does the unit include a basket or rack?
A removable plastic mesh basket is supplied standard. For high-temperature or aggressive chemistry applications, users should source 316 stainless steel accessories separately.
How often should the transducer be recalibrated?
Transducer output is factory-set and non-adjustable. Annual verification of acoustic power output using calorimetric or radiometric methods (per ASTM E1000) is recommended for ISO/IEC 17025-accredited labs.
