Shengyan (Lucky) SCQ-5201 Benchtop Ultrasonic Cleaner

Overview

The Shengyan (Lucky) SCQ-5201 is a benchtop ultrasonic cleaner engineered for precision cleaning of delicate and complex components in research laboratories, quality control environments, and industrial maintenance settings. It operates on the principle of acoustic cavitation—high-frequency sound waves (25, 40, or 60 kHz) generate microscopic vacuum bubbles in the cleaning solution that implode with localized energy, dislodging contaminants from surfaces, crevices, blind holes, and microstructures without mechanical abrasion. Designed for reproducible, non-destructive cleaning of sensitive substrates—including optical lenses, semiconductor wafers, surgical instruments, and precision machined parts—the SCQ-5201 delivers consistent performance across diverse aqueous and mild solvent-based solutions. Its robust stainless steel tank (300 × 240 × 150 mm), integrated sound-dampening lid, and stable 300 W transducer system ensure operational reliability and operator safety in continuous-use laboratory workflows.

Key Features

• Stainless steel construction (SUS304 inner tank and outer housing) resistant to corrosion from water, alcohols, and low-concentration alkaline or acidic cleaning agents.
• Selectable ultrasonic frequency options (25 kHz for heavy-duty degreasing; 40 kHz for general-purpose cleaning; 60 kHz for fine-detail removal on fragile substrates).
• Precise digital timer (1–60 minutes) with automatic shutdown to prevent over-cleaning and solution overheating.
• Integrated sound-dampening lid reduces ambient noise by up to 15 dB(A), meeting ISO 140-3 laboratory acoustic guidelines for shared workspaces.
• Manual drain valve and fill port enable rapid solution exchange without disassembly—critical for multi-step cleaning protocols requiring sequential solvents or rinse stages.
• Compact benchtop footprint (approx. 350 × 300 × 320 mm) optimized for space-constrained labs while accommodating standard labware such as beakers, Petri dishes, and instrument trays.

Sample Compatibility & Compliance

The SCQ-5201 is compatible with a broad range of sample types, including but not limited to: glassware (volumetric flasks, cuvettes, pipettes), metal components (stainless steel surgical tools, bearing assemblies, fuel injectors), ceramic and quartz optics, printed circuit boards (PCBs), and polymer-based filters. It supports cleaning protocols aligned with ASTM D2603 (Standard Test Method for Sonic Shear Stability of Hydraulic Fluids) and ISO 13485–compliant device reprocessing workflows when used with validated detergents. While the unit itself does not incorporate heating or programmable ramping, its design facilitates integration into GLP- and GMP-aligned cleaning SOPs—particularly where temperature-controlled baths are external or where ambient-temperature ultrasonic treatment is specified (e.g., USP environmental surface decontamination validation). The absence of adjustable power or temperature controls ensures fixed-parameter repeatability, supporting audit-ready documentation under FDA 21 CFR Part 11 when paired with electronic logbooks.

Software & Data Management

The SCQ-5201 is a standalone hardware platform with no embedded software, firmware, or network interface. All operational parameters are controlled via front-panel tactile buttons and a 3-digit LED display. This architecture eliminates cybersecurity risks associated with connected instrumentation and ensures long-term compatibility with evolving IT infrastructure. For laboratories requiring traceability, manual logging of cycle parameters (frequency selected, duration, solution batch ID, operator initials) satisfies basic ALCOA+ data integrity principles. Optional third-party USB data loggers (e.g., HOBO UX120-compatible units) may be deployed externally to record ambient temperature and acoustic output stability over time—supporting preventive maintenance scheduling per ISO/IEC 17025 Clause 6.4.2.

Applications

• Pre-analytical sample preparation: removal of organic residues from HPLC vials, GC autosampler syringes, and ICP-MS nebulizer components.
• Biochemistry & cell biology: gentle dissociation of adherent cells from culture plates prior to lysis; degassing of agarose gels and electrophoresis buffers.
• Materials science: cleaning of sputter targets, TEM grids, and MEMS devices prior to coating or metrology.
• Maintenance engineering: restoration of carburetors, hydraulic valves, and turbine blades contaminated with carbon deposits or machining oils.
• Educational use: demonstration of cavitation physics, sonochemistry fundamentals, and surface tension effects in undergraduate physics and chemistry labs.

FAQ

Is the SCQ-5201 compliant with CE or UL safety standards?
The SCQ-5201 meets GB 4706.1–2005 (Chinese national standard equivalent to IEC 60335-1) for household and similar electrical appliances. CE marking is not applied; users requiring CE-compliant operation must verify local regulatory acceptance or pursue third-party certification.
Can I use flammable solvents such as acetone or ethanol in this unit?
No. The SCQ-5201 lacks explosion-proof construction, intrinsically safe transducers, or vapor recovery systems. Only aqueous or non-flammable, low-volatility cleaning solutions (e.g., Alconox®, Tergazyme®) are recommended.
Does the unit include a degassing function?
No dedicated degassing mode is provided. However, initiating a 5–10 minute ultrasonic cycle with fresh solution at 40 kHz achieves effective air removal from both liquid and submerged parts prior to critical cleaning steps.
What maintenance is required for long-term reliability?
Monthly inspection of the drain valve seal integrity, biannual cleaning of transducer mounting surfaces with isopropyl alcohol, and annual verification of timer accuracy using a calibrated stopwatch are advised per manufacturer service guidelines.
Is the stainless steel tank passivated per ASTM A967?
Yes—the SUS304 tank undergoes nitric acid passivation post-fabrication to enhance corrosion resistance in chloride-containing solutions, consistent with ASTM A967 Method A.
