Overview
The Zhonghuanbeifang ZC-190D Desktop Digital Ultrasonic Cleaner is an entry-level benchtop ultrasonic cleaning system engineered for precision and repeatability in routine laboratory, quality control, and light industrial applications. It operates on the principle of cavitation—generated by high-frequency (40 kHz) acoustic energy transmitted through a liquid medium—to dislodge particulate contaminants, organic residues, and loosely adhered films from submerged components. The transducers are integrated into the bottom of a seamless, one-piece deep-drawn 304 stainless steel tank, minimizing structural seams and enhancing long-term corrosion resistance and leak integrity. Designed for consistent performance across variable load conditions, the unit delivers stable ultrasonic energy output at 360 W nominal power, with independent digital control over both cleaning duration and solution temperature—critical parameters influencing cavitation intensity and solvation efficiency.
Key Features
- Digital microprocessor-based control panel with LED display for real-time monitoring and precise setting of time (0–99 minutes) and temperature (ambient to 80 °C)
- Robust 304 stainless steel tank formed via single-stage deep drawing—eliminates weld seams, improves structural rigidity, and ensures superior fluid containment integrity
- Acoustically optimized lid with integrated damping material to reduce airborne noise emissions and prevent solvent evaporation during operation
- High-efficiency piezoelectric transducers operating at 40 kHz, tuned for broad-spectrum contaminant removal without excessive surface erosion
- Stainless steel housing constructed from brushed-grade 304 SS, providing mechanical durability and compatibility with common lab cleaning agents and mild disinfectants
- Optional argon-welded stainless steel mesh basket (304 grade) available for improved part suspension, uniform energy distribution, and enhanced rinsing efficiency
Sample Compatibility & Compliance
The ZC-190D accommodates a wide range of sample geometries and materials—including glassware (vials, cuvettes, pipette tips), metal tools (tweezers, forceps, surgical instruments), ceramic substrates, and polymer components—provided they are chemically compatible with aqueous or mild solvent-based cleaning solutions. Its 19 L tank volume (internal dimensions: 330 × 300 × 200 mm) supports batch processing of multiple small-to-medium-sized items simultaneously. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device’s digital setpoint logging capability (time/temperature) supports basic GLP-aligned documentation when paired with external audit trails. It complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity standards) for laboratory environments.
Software & Data Management
The ZC-190D operates via embedded firmware with no external software dependency. All operational parameters—including elapsed time, set temperature, and active heating status—are displayed continuously on a dual-segment LED interface. No data export, remote control, or PC connectivity is provided; however, the digital timer and thermostat retain user-defined setpoints across power cycles, supporting procedural consistency in standardized cleaning protocols. For regulated environments requiring electronic records, integration with external environmental loggers or manual SOP-based documentation is recommended to fulfill traceability requirements under ISO/IEC 17025 or GMP Annex 11.
Applications
- Routine cleaning of analytical glassware prior to HPLC, GC, or spectrophotometric analysis
- Preparation of semiconductor wafers and MEMS devices for inspection or coating processes
- Decontamination of reusable laboratory tools between experiments (e.g., electrophoresis combs, gel trays)
- Removal of flux residues from printed circuit boards (PCBs) in electronics prototyping labs
- Supporting ASTM D2247 (standard practice for testing corrosion resistance of coatings) via controlled pre-test substrate cleaning
- Assisting USP <797> and <800> compliance workflows by enabling reproducible cleaning of compounding equipment surfaces
FAQ
Is the ZC-190D suitable for cleaning delicate optics or coated lenses?
Yes—when operated at lower temperatures (20–40 °C) and shorter durations (3–10 min) with low-surfactant aqueous solutions, it is appropriate for non-abrasive cleaning of optical components. Avoid chlorinated or highly alkaline solvents.
Does the unit include a drain valve for easy solution disposal?
No—this model does not feature a built-in drain port. Solution removal requires manual decanting or siphoning.
Can the ultrasonic power output be adjusted during operation?
No—the ultrasonic power is fixed at 360 W. Only time and temperature are digitally adjustable.
What safety certifications does the ZC-190D carry?
It meets CE-marked EMC and LVD requirements per EN 61326-1 and EN 61010-1 for laboratory electrical equipment. No UL or CSA listing is provided.
Is the stainless steel tank passivated post-manufacture?
While not explicitly documented in the specification sheet, the use of 304 stainless steel and one-piece draw-forming process inherently minimizes free iron contamination; users performing critical applications should verify passivation status per ASTM A967 if required.
