Shengyan SCQ-9201A Digital Ultrasonic Cleaner

Overview

The Shengyan SCQ-9201A Digital Ultrasonic Cleaner is an industrial-grade benchtop cleaning system engineered for reproducible, high-intensity cavitation-based decontamination in regulated laboratory and light manufacturing environments. It operates on the principle of ultrasonic cavitation: high-frequency acoustic energy (25–80 kHz) induces rapid pressure fluctuations in aqueous or solvent-based cleaning media, generating transient microbubbles that collapse with localized energy densities exceeding 5,000 K and 1,000 atm. This physical mechanism enables non-contact removal of particulate contaminants, organic residues, biofilms, oxides, polishing compounds, and microbial agents from complex geometries—including blind holes, capillary channels, and microstructured surfaces—without mechanical abrasion or chemical aggressiveness. Designed for routine use in QC labs, R&D facilities, and maintenance workshops, the SCQ-9201A delivers consistent cleaning performance across diverse sample types while maintaining compliance-ready operational transparency.

Key Features

• 30-liter full 304 stainless steel tank (500 × 300 × 200 mm internal dimensions) fabricated via argon arc welding for structural integrity and corrosion resistance.
• Digital LED timer with precise 1–600 minute programmable range, supporting repeatable process validation and SOP adherence.
• Multi-frequency selection (25 / 28 / 40 / 59 / 60 / 80 kHz) allows optimization for varying contaminant adhesion strength and substrate sensitivity—lower frequencies for heavy particulates, higher frequencies for fine particulate or delicate components.
• 600 W total ultrasonic output distributed across multiple high-efficiency piezoelectric transducers (50 W nominal per unit), ensuring uniform energy distribution and minimized standing wave interference.
• Integrated ceramic heating system with temperature capability up to 80 °C; heater activation is manually initiated and monitored via analog dial (no digital setpoint control).
• Sound-dampening hinged lid reduces ambient noise to <65 dB(A) at 1 m distance, improving workplace ergonomics and meeting ISO 14001 environmental management considerations.
• Manual bottom drain valve facilitates safe, residue-free media exchange; compatible with standard lab floor drains and waste containment protocols.
• PCB board conformally coated to IPC-CC-830B Class 3 standards for long-term reliability in humid or chemically exposed environments.
• Stainless steel mesh basket included (SUS304, 0.8 mm wire diameter, 2 mm aperture) for optimal part suspension and acoustic coupling.

Sample Compatibility & Compliance

The SCQ-9201A accommodates a broad range of sample formats including glassware (vials, flasks, cuvettes), metal components (surgical instruments, precision gears, calibration standards), semiconductor wafers (pre-photolithography), optical lenses, printed circuit boards, and porous ceramics. Its open architecture supports custom fixtures and immersion racks. While not certified to IEC 61000-6-3 (EMC) or UL 61010-1 out-of-the-box, the unit meets baseline electrical safety requirements for Class I equipment operating at 220 VAC / 50 Hz. For GLP/GMP applications, users may implement supplementary documentation controls—including logbook entries for time/temperature/frequency settings—and integrate manual verification steps into cleaning validation protocols aligned with ASTM D4167, ISO 13485 Annex A.3, and USP Cleaning Validation of Laboratory Equipment.

Software & Data Management

The SCQ-9201A is a standalone hardware platform with no embedded firmware, network interface, or data export capability. All operational parameters are set and verified manually: timer duration via rotary encoder, frequency selection via toggle switch, and heater activation via dedicated power switch. This design eliminates cybersecurity risks associated with connected devices and simplifies audit readiness—every parameter change is physically observable and operator-logged. For laboratories requiring electronic records, integration with external environmental monitoring systems (e.g., Vaisala viewLinc or DeltaTRAK) is achievable via dry-contact relay outputs (optional accessory). Audit trails must be maintained manually per FDA 21 CFR Part 11 Subpart B §11.10(a) for systems lacking electronic signature functionality.

Applications

• Mechanical engineering: Removal of rust inhibitors, machining oils, carbon deposits, and filter media blockages from engine assemblies and hydraulic components.
• Medical device reprocessing: Pre-sterilization cleaning of endoscopes, biopsy forceps, and laparoscopic instruments per AAMI ST91 guidelines.
• Electronics manufacturing: Residue removal from SMT stencils, solder paste dispensing nozzles, and bare PCBs prior to AOI inspection.
• Pharmaceutical R&D: Cleaning of dissolution apparatus vessels, HPLC injection vials, and tablet punch tooling to prevent cross-contamination.
• Academic research: Decontamination of electron microscopy grids, NMR sample tubes, and microfluidic chips prior to surface characterization.
• Jewelry and optics: Gentle yet effective removal of polishing compounds, skin oils, and atmospheric particulates from precious metals and coated lenses.

FAQ

Is the ultrasonic frequency selectable during operation?
Yes—the unit provides six fixed-frequency options (25, 28, 40, 59, 60, and 80 kHz) selected via front-panel toggle switch prior to initiating the cleaning cycle.
Does this model support automatic temperature regulation?
No—it includes a ceramic heating element capable of reaching up to 80 °C, but temperature is not digitally controlled or feedback-regulated; users monitor and adjust manually.
Can the SCQ-9201A be used with flammable solvents?
No—this unit is designed exclusively for aqueous solutions and water-miscible detergents. Use with flammable or chlorinated solvents poses fire, explosion, and material compatibility hazards.
What is the expected service life of the transducers under continuous operation?
When operated within rated duty cycles (≤8 hours/day, with ≥30-minute cooldown intervals), the transducers exhibit typical lifespans exceeding 10,000 operational hours, consistent with IEC 60512-11-20 vibration endurance specifications.
Is validation documentation provided with the instrument?
Factory test reports include basic functional verification (timer accuracy ±1%, heater stability ±3 °C at 60 °C); full IQ/OQ/PQ documentation must be developed by the end user per ISO/IEC 17025 Clause 5.5.2.
