KQ-100VDE / KQ-100VDB / KQ-100VDV Benchtop Dual-Frequency Digital Ultrasonic Cleaner

Overview

The KQ-100VDE, KQ-100VDB, and KQ-100VDV are benchtop dual-frequency digital ultrasonic cleaners engineered for precision cleaning, degassing, dispersion, emulsification, and cell lysis in academic laboratories, R&D facilities, quality control labs, and light industrial settings. These units operate on the principle of acoustic cavitation—where high-frequency sound waves generate microscopic vacuum bubbles in liquid media that rapidly collapse, producing localized shockwaves and intense shear forces. The dual-frequency capability (40 kHz and 80 kHz) enables optimized performance across diverse sample types: lower frequency delivers higher energy for robust particulate removal from machined parts or glassware, while higher frequency provides finer, gentler agitation ideal for delicate biological samples, microelectronics, or nanoparticle suspensions. All models integrate a fully sealed, corrosion-resistant 304 stainless steel tank with precise digital control of ultrasonic power, heating, timing, and thermal regulation—ensuring repeatability and compliance with standard laboratory operational protocols.

Key Features

• Dual-frequency operation (40 kHz / 80 kHz) with independent frequency selection via front-panel interface
• 100 W total ultrasonic output distributed across two 50 W piezoelectric transducers bonded to the tank bottom for uniform energy distribution
• Digital microcontroller-based control system with real-time LCD display of set/actual temperature, elapsed time, power level, and safety status indicators
• Precision temperature control (40–100 °C, ±1 °C accuracy) via 400 W built-in heating element with PID algorithm
• Programmable timer (1–999 minutes) with auto-shutdown and memory retention of last-used parameters
• Comprehensive safety architecture: low-fluid-level detection, over-temperature cutoff, over-voltage and over-current monitoring, and automatic fault logging
• Stainless steel construction throughout—tank, basket (argon-welded 304 SS mesh), and outer chassis—ensuring chemical resistance and long-term structural integrity
• Sound-dampening lid included on KQ-100VDE and KQ-100VDV models to reduce ambient noise (<55 dB(A) at 1 m) and minimize solvent evaporation
• Cumulative operational hour counter (0–999,999 h) supporting maintenance scheduling and GLP-compliant equipment lifecycle tracking

Sample Compatibility & Compliance

These cleaners accommodate a broad range of sample formats—including glass vials, metal fixtures, optical lenses, semiconductor wafers, surgical instruments, and biological tissue specimens—when immersed in compatible aqueous or mild organic solvents (e.g., isopropanol, ethanol, aqueous alkaline or acidic solutions). The stainless steel tank and mesh basket resist corrosion from common lab cleaning agents, including sodium hydroxide, citric acid, and low-concentration peroxides. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the digital parameter logging, tamper-resistant settings, and audit-ready cumulative runtime support alignment with GLP and GMP documentation requirements. Units comply with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity), and meet CE marking requirements for laboratory equipment within the European Economic Area.

Software & Data Management

No external software or PC connectivity is required—the embedded firmware handles all operational logic, parameter storage, and safety interlocks autonomously. All user-defined settings—including frequency mode, temperature setpoint, timer duration, and power level—are retained in non-volatile memory after power cycling. The digital display continuously logs real-time system variables, enabling manual recordkeeping for SOP adherence. For regulated environments, users may document operational parameters (date/time, temperature, duration, frequency) alongside batch or sample IDs in laboratory notebooks or LIMS-integrated spreadsheets. Optional calibration certificates (traceable to NIST standards) are available upon request for temperature and timer verification.

Applications

• Routine cleaning of pipettes, cuvettes, filters, and HPLC components prior to analysis
• Removal of polishing compounds, flux residues, and oxide layers from precision optics and MEMS devices
• Cell disruption and organelle extraction in molecular biology workflows (e.g., bacterial lysis, mitochondrial isolation)
• Accelerated solvent extraction of plant metabolites, soil contaminants, or polymer additives
• Ultrasonic degassing of resin mixtures, coating solutions, and casting media to eliminate microbubbles
• Homogenization of colloidal suspensions, liposomes, and nanomaterial dispersions
• Preparation of reference standards and calibration solutions requiring particle-free solvents

FAQ

What is the difference between the KQ-100VDB, KQ-100VDE, and KQ-100VDV models?
The VDB model features a compact footprint (260×160×260 mm) without a sound-dampening lid; the VDE adds the lid and shares the same dimensions; the VDV offers increased tank depth (130 mm vs. 100 mm) and overall size (340×250×330 mm) for larger or taller samples.
Can these units be used with flammable solvents?
No—these cleaners lack explosion-proof certification and must only be operated with non-flammable or low-volatility aqueous solutions. Use in ventilated fume hoods is recommended when volatile solvents are unavoidable.
Is the heating function independently controllable from ultrasonication?
Yes—temperature can be set and maintained without activating ultrasound, enabling standalone warming or pre-heating of cleaning baths.
How often should the transducers be serviced or recalibrated?
Under normal use, no routine transducer servicing is required. Annual verification of temperature accuracy and timer consistency is advised for GLP-compliant labs.
Does the unit include a drain valve?
Yes—all models feature a manually operated drain valve located at the tank base for efficient solution disposal.
