ZiQi ZQ-40DHL 10L Benchtop Digital Ultrasonic Cleaner with Adjustable Power, Heating & Timer

Overview

The ZiQi ZQ-40DHL is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, dispersion, emulsification, and cell disruption in laboratory, R&D, and quality control environments. 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 balance between cleaning intensity and sample integrity, making it suitable for delicate components as well as robust industrial parts. The unit integrates three independently controllable parameters—ultrasonic power (100–240 W), heating temperature (ambient to 80 °C), and cleaning duration (1–30 minutes)—all displayed and adjusted via an intuitive LED digital interface. Its 10-liter capacity accommodates larger samples or multiple small parts simultaneously, supporting throughput-critical workflows without compromising reproducibility.

Key Features

• Continuously adjustable ultrasonic power output (100–240 W) enables method optimization across diverse sample types—from optical lenses to metal substrates—without over-cavitation or insufficient energy transfer.
• Digital temperature control (ambient to 80 °C) ensures consistent thermal conditions during cleaning or solvent-assisted extraction, critical for temperature-sensitive protocols such as enzymatic decontamination or polymer dissolution.
• Precise timer function (1–30 min) with automatic shutdown prevents overexposure and supports unattended operation under validated SOPs.
• One-piece, seamless stainless steel tank formed via deep-drawing—eliminating weld seams that compromise corrosion resistance and long-term structural integrity.
• Integrated sound-dampening lid reduces airborne noise to ≤55 dB(A) at 1 m distance, meeting occupational safety guidelines for shared lab spaces.
• Front-panel LED display provides real-time feedback of set values and operational status; all controls are tactile and glove-compatible for use in cleanroom or protective-gear environments.
• Manual drain valve facilitates rapid, residue-free tank emptying—essential for solvent switching, maintenance, or compliance with chemical handling regulations.

Sample Compatibility & Compliance

The ZQ-40DHL is compatible with aqueous, alcoholic, and low-viscosity organic solvents (e.g., isopropanol, acetone, ethanol), provided they fall within flash point and material compatibility limits of 304 stainless steel construction. Its design adheres to general-purpose laboratory equipment safety standards (IEC 61010-1) and incorporates grounding continuity, over-temperature cutoff, and dry-run protection. While not certified for medical device reprocessing per ISO 15883 or sterilization per ANSI/AAMI ST79, it supports GLP-aligned cleaning validation when paired with documented parameter logs and traceable calibration records. Users performing regulated work (e.g., pharmaceutical QC per USP , ASTM D2603 for ultrasonic cleaning efficacy) may integrate external data loggers for audit-ready temperature and time verification.

Software & Data Management

This model operates as a standalone instrument with no embedded software or network connectivity. All operational parameters are stored locally in non-volatile memory and persist through power cycles. For laboratories requiring electronic recordkeeping, the ZQ-40DHL supports manual entry into LIMS or ELN systems via its deterministic, repeatable settings—each combination of power, temperature, and time constitutes a defined cleaning protocol. Optional accessories—including calibrated PT100 temperature probes and third-party USB data loggers—enable traceable monitoring compliant with FDA 21 CFR Part 11 when deployed with appropriate procedural controls and user access management.

Applications

• Removal of particulate contaminants, oils, and flux residues from precision optics, semiconductor wafers, and microfluidic devices.
• Accelerated solvent-based extraction of plant metabolites, nucleic acids, or lipids in analytical chemistry and natural product research.
• Cell lysis and homogenization for protein isolation, particularly where mechanical shear must be minimized relative to bead-beating methods.
• Degassing of viscous solutions prior to casting, coating, or vacuum impregnation processes.
• Pre-cleaning of HPLC vials, GC autosampler trays, and pipette tips to reduce carryover and background interference.
• Supporting ASTM E1728 and ISO 12103-1 test dust removal validation in materials science labs.

FAQ

Is the ultrasonic frequency adjustable?
No—the ZQ-40DHL operates exclusively at 40 kHz, a frequency selected for broad-spectrum cleaning efficiency and stable cavitation field distribution across the 10 L tank volume.
Can this unit be used with flammable solvents?
Only under strict engineering controls: ventilation, explosion-proof environment, and exclusion of ignition sources. The heater and transducers are not intrinsically safe; consult local EH&S policies before solvent selection.
What is the maximum recommended operating temperature for continuous use?
80 °C is the upper limit for sustained operation. Prolonged exposure above 70 °C may accelerate transducer aging and reduce long-term power stability.
Does the unit include a stainless steel basket?
A stainless steel mesh basket is optional and sold separately; the standard configuration includes only the tank, lid, and drain valve.
How often should the tank be descaled?
Frequency depends on water hardness and usage intensity. In hard-water areas, descaling every 2–4 weeks using 5% citric acid solution is recommended to maintain transducer coupling efficiency and temperature uniformity.
