KQ-100DA Desktop Digital Ultrasonic Cleaner (4 L)

Overview

The KQ-100DA Desktop Digital Ultrasonic Cleaner is a compact, benchtop-grade ultrasonic cleaning system engineered for precision and reliability in laboratory, academic, and light industrial environments. It operates on the principle of high-frequency ultrasonic cavitation—generating microscopic vacuum bubbles in liquid media at 40 kHz, which collapse violently to produce localized shockwaves and microstreaming. This physical mechanism enables effective removal of particulate contaminants, organic residues, oxides, and biofilms from delicate substrates—including glassware, metal parts, optical components, semiconductor wafers, and biological samples—without mechanical abrasion or chemical aggression. Designed for consistent performance across small-batch applications, the KQ-100DA integrates digital control logic with robust electromechanical architecture to support critical tasks such as degassing solvents, accelerating extraction protocols, facilitating cell lysis, and preparing surfaces for analytical or coating processes.

Key Features

• Dual 50 W piezoelectric transducers mounted directly to the stainless steel tank base, delivering uniform 40 kHz energy distribution and stable cavitation intensity across the full 4 L working volume.
• Full digital interface with real-time display of set and actual temperature, elapsed/remaining time, ultrasonic power level, and cumulative operational hours (retained in non-volatile memory).
• Precision temperature control (ambient to 80 °C, ±1 °C) enabled by a 200 W heating element and PID-regulated feedback loop—critical for temperature-sensitive cleaning, enzymatic reactions, or solvent-based extractions.
• Integrated safety architecture including automatic shutdown upon low liquid level detection, thermal cutoff at >90 °C, and electronic protection against voltage surges and current overload.
• 304 stainless steel tank and housing ensure long-term corrosion resistance, compatibility with aqueous and mild solvent-based cleaning solutions, and compliance with ISO 13485-aligned lab equipment durability requirements.
• Removable, argon-welded stainless steel mesh rack optimized for sample stability and acoustic transparency—minimizing shadowing effects and ensuring uniform exposure to ultrasonic energy.
• Built-in drain valve with leak-proof brass body and food-grade silicone gasket for controlled, spill-free solution disposal—reducing operator exposure and enabling rapid bath replenishment.

Sample Compatibility & Compliance

The KQ-100DA accommodates a broad range of sample geometries and material classes, including but not limited to borosilicate glass vials, quartz cuvettes, stainless steel tools, aluminum fixtures, ceramic substrates, and polymer-based microfluidic chips. Its 4 L capacity supports standard laboratory vessels up to 100 mm in height and 80 mm in diameter. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity), and its construction meets RoHS Directive 2011/65/EU restrictions on hazardous substances. While not certified for sterile processing per ISO 13408 or FDA 21 CFR Part 820, the KQ-100DA is routinely deployed in GLP-compliant laboratories for preparatory cleaning steps preceding validated sterilization or analytical workflows.

Software & Data Management

The KQ-100DA employs an embedded 8-bit microcontroller with onboard EEPROM storage, eliminating external software dependencies. All user-defined parameters—including time (1–99 min), temperature setpoint, and ultrasonic power level—are retained after power cycling. The cumulative hour counter logs total operational lifetime with second-level resolution, supporting preventive maintenance scheduling and audit-ready usage records. No USB, Bluetooth, or network connectivity is provided; data integrity relies on hardware-level memory redundancy and watchdog timer supervision—aligning with environments where cybersecurity constraints preclude connected instrumentation.

Applications

• Routine cleaning of HPLC columns, syringe filters, and autosampler vials prior to chromatographic analysis.
• Degassing of mobile phases and calibration standards to eliminate bubble formation in flow systems.
• Cell disruption and organelle isolation in molecular biology workflows using buffered saline or detergent-based lysis media.
• Surface preparation of electrodes, sensors, and MEMS devices prior to thin-film deposition or electrochemical characterization.
• Extraction of phytochemicals, lipids, or nucleic acids from plant or tissue matrices under controlled thermal-acoustic conditions.
• Removal of polishing compounds and machining oils from precision optics and metrology artifacts.

FAQ

What is the recommended cleaning solution for general laboratory use?
Deionized water or 1–2% laboratory-grade detergent (e.g., Alconox® or Liquinox®) is suitable for most non-critical applications. Avoid halogenated solvents unless confirmed compatible with 304 stainless steel and O-ring materials.
Can the KQ-100DA be used for sterilization?
No. Ultrasonic cleaning removes contaminants but does not achieve microbial kill levels required for sterilization. It serves as a preparatory step before autoclaving, ethylene oxide treatment, or hydrogen peroxide plasma processing.
Is the unit compliant with FDA 21 CFR Part 11 for electronic records?
No. The KQ-100DA lacks audit trail generation, electronic signature capability, or user access controls required under Part 11. It is intended for use in non-GxP or early-stage R&D settings.
How often should the tank be descaled?
Frequency depends on water hardness and usage intensity. In hard water areas, descaling with 5% citric acid solution every 2–4 weeks is advised to maintain transducer efficiency and temperature sensor accuracy.
Does the unit include a lid or noise-reduction cover?
The KQ-100DA model does not include a lid. For noise mitigation (<65 dB(A) at 1 m), users may install third-party acrylic enclosures rated for ultrasonic transmission—though this may slightly attenuate cavitation intensity.
