ZiQi ZQ-30H 6L Benchtop Mechanical Knob-Controlled Heated Ultrasonic Cleaner

Overview

The ZiQi ZQ-30H is a benchtop heated ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in academic laboratories, industrial R&D facilities, and quality control environments. It operates on the principle of high-frequency ultrasonic cavitation—generated at a stable 40 kHz frequency—to produce microscopic implosions in the cleaning medium, effectively dislodging particulate contaminants, oxides, and organic residues from surfaces and complex geometries. Integrated resistive heating enables temperature-controlled cleaning between ambient conditions and 80 °C, enhancing solvent efficacy for stubborn soils or low-volatility media. With a 6-liter stainless-steel tank (300 × 150 × 150 mm internal dimensions), the ZQ-30H supports medium-volume batch processing of larger components—including optical lenses, metal fixtures, printed circuit boards, and laboratory glassware—without requiring continuous media replenishment.

Key Features

• Robust 180 W ultrasonic transducer array with imported piezoelectric elements, delivering consistent energy distribution across the entire tank volume.
• Seamless, one-piece drawn stainless-steel tank construction eliminates weld seams—reducing corrosion initiation points and improving long-term fluid integrity and leak resistance.
• Dual mechanical controls: a rotary timer dial (1–30 min) and independent temperature knob (20–80 °C), enabling intuitive, non-digital operation without software dependencies or calibration drift concerns.
• Integrated sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance, supporting compliance with occupational health guidelines in shared lab spaces.
• Front-mounted manual drain valve facilitates rapid, tool-free media exchange—critical for multi-step cleaning protocols involving sequential solvents or aqueous/organic transitions.
• High-efficiency thermal management system maintains stable bath temperature during extended cycles; external cooling fins and optimized heater placement prevent localized overheating near transducers.
• Full 304 stainless-steel construction for both inner tank and outer chassis ensures chemical compatibility with common aqueous detergents, alcohols, and mild alkaline solutions.

Sample Compatibility & Compliance

The ZQ-30H accommodates a broad range of sample types—including metallic, ceramic, polymer, and glass substrates—without risk of surface etching or dimensional distortion under standard operating parameters. Its fixed 40 kHz frequency is optimized for general-purpose cleaning rather than high-resolution particle removal (e.g., sub-micron semiconductor wafers), making it suitable for QC labs, maintenance workshops, and preparatory workflows in materials science and life sciences. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its mechanical-only interface inherently satisfies audit requirements for traceability simplicity in GLP/GMP-aligned facilities where electronic logging is not mandated. All electrical components meet IEC 61010-1 safety standards for laboratory equipment; CE marking applies per EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).

Software & Data Management

As a purely electromechanical instrument, the ZQ-30H does not incorporate embedded firmware, touchscreen interfaces, or data export capabilities. This design philosophy prioritizes operational reliability, service longevity, and minimal failure modes—particularly advantageous in environments with limited IT support, electromagnetic interference, or strict cybersecurity policies. Process parameters (time and temperature) are set via tactile knobs with physical detents, ensuring repeatable settings without reliance on memory retention or battery-backed clocks. For laboratories requiring documentation, users may integrate external calibrated thermometers and stopwatch logs into SOPs compliant with ISO/IEC 17025 clause 7.7 (measurement traceability) or ASTM D2603 (ultrasonic cleaning validation protocols).

Applications

• Removal of machining oils, polishing compounds, and flux residues from precision machined parts prior to metrology or coating.
• Pre-analytical cleaning of HPLC vials, GC liners, and autosampler needles to prevent cross-contamination in chromatographic workflows.
• Cell lysis and homogenization support in molecular biology—when used with appropriate buffers and controlled duration to avoid nucleic acid shearing.
• Degassing of viscous solvents (e.g., silicone oils, glycerol-water mixtures) prior to viscosity or refractive index measurements.
• Extraction of active compounds from botanical matrices in natural product research, leveraging thermal enhancement of mass transfer kinetics.
• De-bubbling of casting resins and dental impression materials before curing to eliminate void defects.

FAQ

Is the ultrasonic power output adjustable?
No—the ZQ-30H delivers a fixed 180 W nominal acoustic power. Output stability is maintained via regulated transformer supply and thermal cutoff protection.
Can the unit be operated without the sound-dampening lid?
Yes, though operation without the lid increases audible noise and reduces cavitation efficiency due to surface wave dissipation; lid use is recommended for optimal performance and operator comfort.
What is the maximum recommended liquid level for safe operation?
Fill the tank to within 30 mm below the top rim (approx. 5.5 L capacity) to ensure adequate transducer immersion and prevent overflow during active cavitation.
Does the heater have overtemperature protection?
Yes—a redundant bimetallic thermal cutoff switch interrupts power if internal temperature exceeds 90 °C, independent of the main thermostat.
Is the drain valve compatible with standard laboratory tubing?
The outlet features a 1/4″ BSP female thread, allowing direct connection to Tygon® or Viton® tubing using a standard compression fitting (not supplied).
