ZiQi ZQ-80DH 22L Benchtop Digital Ultrasonic Cleaner with Heating

Overview

The ZiQi ZQ-80DH is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in research laboratories, quality control environments, and industrial R&D settings. It operates on the principle of high-frequency cavitation—40 kHz ultrasonic energy transmitted through aqueous or compatible solvent media generates microscopic vacuum bubbles that collapse violently near surfaces, dislodging particulate contaminants, oxides, oils, and biofilms without mechanical abrasion. Integrated heating (up to 80 °C) enhances cleaning efficacy for viscous residues and accelerates solvent-based processes such as extraction and emulsification. Its 22 L tank volume supports large components, multi-part batches, or volumetric sample processing—making it suitable for applications ranging from optical component decontamination to pharmaceutical equipment cleaning and materials science specimen preparation.

Key Features

• Robust stainless steel tank and housing (304-grade), fabricated via seamless deep-drawn forming—eliminating weld seams and improving corrosion resistance and structural integrity.
• Digital microprocessor control with dual LED displays for independent real-time monitoring and adjustment of temperature (±1 °C accuracy) and timer (1–30 min, 1-min increments).
• High-efficiency transducer array with imported piezoelectric elements ensures uniform energy distribution across the entire 500 × 300 × 150 mm cleaning chamber.
• Integrated sound-dampening lid reduces ambient noise to ≤65 dB(A) during operation and minimizes solvent evaporation.
• Active thermal management system includes an internal cooling fan (standard on ≥10 L models) to accelerate cooldown after heating cycles and extend heater lifespan.
• Manual drain valve located at the tank base enables safe, controlled fluid removal without tilting or lifting the unit.
• Heating power rated at 800 W, enabling rapid thermal ramp-up and stable temperature maintenance within ±2 °C over extended cycles.

Sample Compatibility & Compliance

The ZQ-80DH accommodates a wide range of sample types—including metal parts, glassware, ceramic substrates, printed circuit boards, and laboratory fixtures—provided immersion-compatible solvents (e.g., water, isopropyl alcohol, alkaline detergents, or low-surface-tension formulations) are used. It complies with general electrical safety requirements per IEC 61010-1 for laboratory equipment. While not certified for sterile processing or ISO 13485 medical device manufacturing, its design supports GLP-aligned documentation practices: time/temperature logs can be manually recorded, and process parameters are repeatable under defined operating conditions. For regulated environments requiring audit trails, external data loggers may be interfaced via analog output (optional accessory).

Software & Data Management

This model operates via embedded firmware with no PC connectivity or proprietary software suite. All operational parameters are set and verified locally via front-panel controls and dual digital displays. The absence of network interfaces or USB ports ensures electromagnetic compatibility in sensitive instrumentation labs and eliminates cybersecurity exposure vectors. For laboratories implementing electronic recordkeeping (e.g., FDA 21 CFR Part 11 compliance), users may integrate the ZQ-80DH into validated workflows by pairing it with calibrated external thermometers and stopwatch-based timing protocols, documented in standard operating procedures (SOPs). Optional accessories include stainless steel mesh baskets (custom-fit for 500 × 300 mm footprint) and rack-mounted holders for standardized vial or wafer handling.

Applications

• Removal of machining oils, polishing compounds, and flux residues from precision mechanical assemblies.
• Pre-cleaning of chromatography columns, spectrometer cuvettes, and optical lenses prior to calibration or coating.
• Cell lysis and tissue homogenization support in molecular biology workflows using buffered saline or detergent-based lysis media.
• Accelerated solvent extraction of plant metabolites, polymer additives, or environmental contaminants from solid matrices.
• Degassing of casting resins, adhesives, and nanoparticle suspensions to eliminate microbubbles prior to curing or deposition.
• Supporting ASTM D2621 (ultrasonic cleaning verification) and ISO 14405-1 (geometrical product specifications) pre-test surface conditioning.

FAQ

Is the ultrasonic power output adjustable?
No—the ZQ-80DH delivers fixed 480 W nominal acoustic power at 40 kHz. Output stability is maintained via constant-current driver circuitry optimized for consistent cavitation intensity.
Can this unit be used with flammable solvents?
Not recommended. The heater and internal electronics are not explosion-proof. Only aqueous solutions or non-flammable, low-volatility solvents (e.g., ethanol/water mixtures below 40% v/v) should be used under strict ventilation and supervision.
What is the maximum recommended continuous operating time?
For thermal and transducer longevity, continuous operation should not exceed 30 minutes per cycle. A minimum 10-minute cooldown interval is advised between successive cycles when operating above 60 °C.
Does the unit include a warranty or service support outside China?
ZiQi provides a 12-month limited warranty covering material and workmanship defects. International technical support is available via authorized regional distributors; spare parts (transducers, heaters, control boards) are stocked in EU and North American logistics hubs.
How is temperature calibration performed?
Factory-calibrated at 25 °C and 60 °C using NIST-traceable RTD references. End users may verify accuracy using a calibrated immersion thermometer placed centrally in the tank at operating depth (75 mm); deviation >±1.5 °C warrants service recalibration.
