ZiQi ZQ-40DH 10L Benchtop Digital Display Heated Ultrasonic Cleaner

Overview

The ZiQi ZQ-40DH is a benchtop heated ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in academic laboratories, quality control environments, and industrial R&D settings. It operates on the principle of high-frequency cavitation—generated by piezoelectric transducers bonded to the stainless-steel tank bottom—at a fixed frequency of 40 kHz. This frequency delivers optimal energy transfer for removing particulate contaminants, organic residues, and entrapped air from surfaces of medium-to-large components, including optical lenses, metal parts, glassware, and ceramic substrates. Integrated digital temperature control (ambient to 80 °C) enhances cleaning efficacy for temperature-sensitive solvents or applications requiring thermal activation of detergent chemistry. The unit’s robust architecture supports continuous operation under controlled conditions, making it suitable for routine use in ISO/IEC 17025-accredited labs and GLP-compliant workflows.

Key Features

• Seamless one-piece stainless-steel tank formed via deep-drawing—eliminates weld seams, prevents leakage, and ensures long-term corrosion resistance in aqueous and mild solvent environments.
• Digital LED display with independent controls for time (1–30 min) and temperature (room temp to 80 °C), enabling reproducible parameter setup across users and shifts.
• High-efficiency axial cooling fan integrated into the chassis to maintain stable internal electronics temperature during extended heating cycles.
• Standard sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance, improving ergonomic conditions in shared lab spaces.
• Front-mounted manual drain valve with PTFE-sealed brass fitting allows safe, residue-free fluid evacuation without disassembly.
• Stainless-steel housing (304 grade) and reinforced tank base provide mechanical stability and resistance to accidental impact or chemical splash exposure.

Sample Compatibility & Compliance

The ZQ-40DH accommodates a wide range of sample geometries—including large PCBs, machined metal assemblies, multi-well plates, and irregularly shaped instrumentation components—within its 300 × 240 × 150 mm tank dimensions. Its non-aggressive 40 kHz cavitation profile minimizes surface erosion risk for delicate substrates such as anodized aluminum, coated optics, and polymer films. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity standards). While not certified for medical device reprocessing per ISO 15883, it meets general laboratory equipment safety requirements under GB 4793.1–2007 (Chinese equivalent of IEC 61010-1). For regulated environments, users may implement SOP-based validation protocols aligned with ASTM D2603 (ultrasonic cleaning performance assessment) and internal QA documentation requirements.

Software & Data Management

The ZQ-40DH is a standalone hardware platform with no embedded firmware logging or network connectivity. All operational parameters are set locally via tactile push-button interface and retained only during active power cycles. To support auditability in regulated settings, users are advised to document run parameters manually or integrate external data loggers (e.g., USB-connected thermocouple recorders) for temperature traceability. When deployed within GxP frameworks, the instrument can be included in equipment qualification (IQ/OQ/PQ) protocols—particularly for cleaning validation studies where consistent thermal and temporal profiles are critical. Optional accessories—including calibrated PT100 probe kits and stainless-steel mesh baskets—facilitate repeatable positioning and thermal uniformity mapping per USP Analytical Instrument Qualification guidelines.

Applications

• Removal of machining oils, flux residues, and polishing compounds from precision mechanical parts prior to metrology or coating processes.
• Pre-analytical sample preparation for SEM, XRD, and ICP-MS—ensuring contaminant-free surfaces for accurate elemental or structural analysis.
• Cell lysis and tissue homogenization in life science labs using compatible buffers (e.g., RIPA, Tris-EDTA), leveraging controlled thermal input to enhance membrane disruption efficiency.
• Degassing of HPLC mobile phases and casting resins to eliminate microbubbles that compromise column integrity or optical clarity.
• Ultrasonic-assisted extraction of botanical compounds, where elevated bath temperature improves solute diffusion kinetics without thermal degradation.

FAQ

Is the ultrasonic power output adjustable?
No—the ZQ-40DH delivers a fixed 240 W ultrasonic output at 40 kHz. Power modulation is not supported; intensity is controlled indirectly via solvent selection, load geometry, and immersion depth.
What is the maximum recommended operating temperature for aqueous solutions?
The heater is rated for continuous operation up to 80 °C. For prolonged use above 60 °C, ensure adequate ventilation around the unit and avoid volatile organic solvents due to flashpoint and vapor pressure constraints.
Does the unit include a built-in drain pump?
No—it features a manual brass drain valve only. Pump-assisted drainage requires external peristaltic or vacuum systems.
Can this cleaner be used with flammable solvents?
Not recommended. The ZQ-40DH lacks explosion-proof certification (ATEX/IECEx) and heating elements are not intrinsically safe. Only water-based or low-volatility, non-flammable cleaning agents should be used.
Is calibration documentation provided with shipment?
Factory calibration certificates for temperature and timer functions are available upon request at order stage; they are not included by default but may be added as a value-added service for regulated users.
