ZiQi ZQ-30DH 6L Benchtop Digital Display Heated Ultrasonic Cleaner

Overview

The ZiQi ZQ-30DH is a benchtop heated 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 ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate microscopic implosions in the cleaning liquid, effectively dislodging particulate contaminants, oxides, and organic residues from surfaces without mechanical abrasion. Integrated heating (up to 80 °C) enhances solvent activity and accelerates cleaning kinetics, particularly for viscous or temperature-sensitive samples. The unit features a fully digital interface for independent control of time and temperature, ensuring repeatability across sequential cleaning cycles. Designed for daily use in regulated environments, its robust stainless-steel construction and sealed transducer assembly support long-term operational stability and compliance with general laboratory safety standards.

Key Features

• High-reliability ultrasonic transducers sourced from certified international suppliers, delivering consistent 40 kHz cavitation energy distribution across the tank volume.
• Seamless, one-piece drawn stainless-steel tank (304 grade) with no weld seams—eliminating crevices where contaminants may accumulate and improving corrosion resistance and structural integrity.
• Dual-layer housing: inner tank and outer casing both fabricated from electropolished 304 stainless steel, offering superior chemical resistance and ease of decontamination.
• Digital LED display with independent rotary knobs for precise setting of cleaning duration (1–30 minutes) and bath temperature (ambient to 80 °C) in 1 °C increments.
• Integrated sound-dampening lid reduces airborne noise to ≤55 dB(A) during operation, meeting standard laboratory acoustic requirements for shared workspaces.
• Manual drain valve located at the bottom rear of the tank enables controlled fluid evacuation without tilting or lifting the unit—critical for handling hazardous or temperature-sensitive solutions.
• Thermal cut-off protection and over-temperature alarm prevent dry-run damage and ensure safe operation during extended cycles.

Sample Compatibility & Compliance

The ZQ-30DH accommodates a broad range of sample types—including metal components, glassware, ceramic substrates, printed circuit boards, optical lenses, and biological tools—provided they are compatible with aqueous or mild solvent-based cleaning media. Its 300 × 150 × 150 mm tank dimensions allow immersion of medium-to-large parts (e.g., beakers up to 1 L, Petri dish stacks, or small instrument assemblies). While not certified to specific ISO/IEC 17025 or ASTM D2603 test methods out-of-the-box, the device supports method validation per internal SOPs and aligns with common lab practices referenced in ASTM D4290 (Standard Guide for Ultrasonic Cleaning), USP (Cleaning Validation), and ISO 13485 Annex A (for medical device pre-cleaning). All electrical components comply with CE-marked safety directives (IEC 61010-1), and the stainless-steel construction meets FDA-recommended material specifications for non-product-contact lab equipment.

Software & Data Management

The ZQ-30DH operates via embedded microcontroller logic with no external software dependency. All operational parameters—including set time, actual elapsed time, target temperature, real-time bath temperature, and fault codes—are displayed continuously on the front-panel LED interface. Though it lacks network connectivity or data export capability, its deterministic analog control architecture ensures immunity to firmware corruption, electromagnetic interference, or cybersecurity vulnerabilities—making it suitable for GLP/GMP-aligned facilities where audit-trail simplicity and functional reliability take precedence over digital integration. For labs requiring documentation, manual log entries (time, temp, duration, operator ID) can be recorded in paper or electronic lab notebooks per 21 CFR Part 11-compliant workflows.

Applications

• Routine cleaning of volumetric glassware, pipette tips, and filtration apparatus prior to calibration or analytical use.
• Removal of machining oils, polishing compounds, and solder flux residues from precision mechanical and electronic components.
• Pre-treatment of substrates before coating, plating, or surface analysis (e.g., XPS, SEM).
• Cell lysis and tissue homogenization support in molecular biology workflows using compatible buffers.
• Ultrasonic-assisted extraction of plant metabolites or polymer additives in solvent systems.
• Deagglomeration of nanoparticle suspensions and uniform dispersion of colloidal formulations.
• Degassing of HPLC mobile phases and ultrapure water prior to system priming.

FAQ

Is the ultrasonic power output adjustable?
No—the ZQ-30DH delivers a fixed 180 W ultrasonic power at 40 kHz. Power modulation is not supported; intensity is controlled indirectly via cleaning time, temperature, and solution chemistry.
Can this unit be used with flammable solvents?
No—only aqueous solutions or non-flammable, low-volatility solvents (e.g., isopropanol below flash point, ethanol/water mixtures) are recommended. The heater and transducers are not explosion-proof.
What is the maximum recommended fill level for optimal cavitation?
For best performance, maintain liquid levels between 30 mm and 120 mm above the tank bottom—approximately 4–5.5 L in the ZQ-30DH. Overfilling attenuates ultrasonic energy; underfilling risks transducer overheating.
Does the unit include a stainless-steel cleaning basket?
A stainless-steel basket is available as an optional accessory (part no. ZQ-BKT-30); it is not included in the base configuration.
How often should the tank be descaled?
In hard-water regions, descaling with 5% citric acid solution is recommended every 100 operating hours or biweekly—whichever occurs first—to preserve heating efficiency and transducer coupling.
