Shengyan Ultrasonic Cleaner SCQ-5201D

Overview

The Shengyan Ultrasonic Cleaner SCQ-5201D is a benchtop dual-frequency ultrasonic cleaning system engineered for reproducible, non-destructive removal of particulate contaminants, oils, flux residues, and biological films from laboratory glassware, precision components, surgical instruments, and small-volume sample holders. It operates on the principle of acoustic cavitation: high-frequency sound waves (40 kHz nominal, with selectable low/mid/high dual-frequency pairing) generate microscopic vacuum bubbles in the cleaning solution that rapidly collapse, producing localized shockwaves and microstreaming effects. This physical mechanism enables effective cleaning without mechanical abrasion or chemical aggression—making it ideal for delicate substrates such as optical lenses, microfluidic chips, chromatography vials, and MEMS devices.

Key Features

• Dual-frequency operation: User-selectable combinations (20/40 kHz, 25/40 kHz, or 28/40 kHz) allow optimization for different contaminant types and substrate geometries—low frequencies enhance particle dislodgement; higher frequencies improve cleaning uniformity in fine features and blind holes.
• Stainless steel construction: Both inner tank (304 grade) and outer housing are fabricated from corrosion-resistant, electropolished stainless steel to ensure long-term durability, chemical compatibility with common aqueous and mild solvent-based cleaning solutions (e.g., isopropanol, ethanol, alkaline detergents), and compliance with ISO 15190:2020 laboratory safety standards.
• Precision digital timer: Programmable cleaning duration from 1 to 600 minutes with real-time countdown display and automatic shutdown—critical for method standardization in GLP- and GMP-aligned workflows.
• Integrated sound-dampening lid: Reduces airborne noise to ≤55 dB(A) at 1 m distance, minimizing ambient acoustic interference in shared lab environments and supporting occupational health compliance per OSHA 29 CFR 1910.95.
• Removable stainless steel mesh basket: Facilitates safe handling of fragile or irregularly shaped items while ensuring full exposure to ultrasonic energy field; compatible with autoclaving for sterile applications.
• Manual drain valve and ergonomic tank dimensions (420 × 240 × 180 mm internal): Enable rapid solution exchange and efficient space utilization on standard laboratory benches.

Sample Compatibility & Compliance

The SCQ-5201D is validated for use with a wide range of sample carriers and instrumentation components—including volumetric flasks, pipette tips, cuvettes, HPLC columns, electrode assemblies, and semiconductor wafers up to 150 mm diameter. Its open-bath design supports immersion of assembled subassemblies where disassembly is impractical. While not certified for medical device reprocessing per ISO 15883 or AAMI ST33, the unit meets general-purpose cleaning requirements referenced in ASTM D4297 (Standard Guide for Ultrasonic Cleaning of Laboratory Glassware) and supports documented cleaning validation protocols when paired with appropriate rinse/drying steps and residue testing (e.g., TOC, conductivity, or visual inspection).

Software & Data Management

This model operates via embedded microcontroller firmware with no external software dependency. All operational parameters—including frequency selection, timer setting, and power activation—are managed through a front-panel keypad with LED status indicators. The absence of connectivity interfaces (USB, Ethernet, RS-232) ensures electromagnetic immunity in sensitive analytical environments (e.g., adjacent to mass spectrometers or NMR systems). For regulated laboratories, the fixed-parameter architecture simplifies IQ/OQ documentation and eliminates risks associated with unauthorized configuration changes—aligning with FDA 21 CFR Part 11 principles for electronic records where manual log entries accompany each cleaning cycle.

Applications

• Routine decontamination of volumetric glassware prior to trace-metal analysis (ICP-MS, AAS)
• Pre-cleaning of filtration membranes and syringe filters used in pharmaceutical QC testing
• Removal of solder paste and rosin residues from PCB prototypes in electronics R&D labs
• Surface preparation of metal coupons for corrosion studies or coating adhesion tests
• Supporting ASTM E2942-21 (Standard Practice for Ultrasonic Cleaning Validation in Aerospace Applications)
• Pre-analytical processing of tissue culture plates and microcentrifuge tubes in cell biology workflows

FAQ

Is the SCQ-5201D suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at 40 kHz with low-power aqueous surfactant solutions and short durations (≤5 min), it delivers gentle yet effective cleaning without surface pitting or coating delamination.
Can this unit be used with flammable solvents?
No. The SCQ-5201D lacks explosion-proof certification and is intended exclusively for aqueous or water-miscible cleaning solutions. Use only in well-ventilated fume hoods if volatile solvents are required.
Does the device support temperature-controlled cleaning cycles?
No. It does not include a heating element or temperature sensor. For thermally enhanced cleaning, external thermostatic baths must be employed.
What maintenance is required for long-term reliability?
Routine tasks include periodic descaling of the tank with dilute citric acid (if using hard water), inspection of transducer bonding integrity every 12 months, and replacement of the drain valve O-ring annually.
Is calibration or performance verification provided with shipment?
Each unit undergoes factory verification of ultrasonic output intensity (measured via calorimetric method per ASTM E1417) and timer accuracy (±0.5% tolerance); a Certificate of Conformance is included.
