Shengyan Ultrasonic Cleaner SCQ-5211D

Overview

The Shengyan Ultrasonic Cleaner SCQ-5211D is a fixed-frequency, general-purpose benchtop ultrasonic cleaning system engineered for consistent removal of particulate contaminants, organic residues, and loosely adhered films from laboratory glassware, metal components, precision instruments, and small-volume sample holders. It operates on the principle of acoustic cavitation—where high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers bonded to the stainless steel tank base induce rapid formation and collapse of microscopic vapor cavities in the cleaning solution. This implosive energy releases localized shockwaves and microstreaming forces that dislodge surface-bound debris without mechanical abrasion or thermal degradation. Unlike variable-frequency models in the SCQ series, the SCQ-5211D delivers stable, repeatable output at 40 kHz—a frequency widely validated for balanced penetration depth and surface cleaning efficacy across aqueous and mild solvent-based media. Its 14 L tank volume supports standard beakers (up to 1000 mL), crucibles, pipette tips, filtration housings, and small optical components, making it suitable for QC labs, R&D facilities, and academic teaching environments requiring reliable, low-maintenance cleaning performance.

Key Features

• Stainless steel tank (300 × 240 × 200 mm internal dimensions) and outer housing for corrosion resistance and structural integrity
• Digital timer with precise 1–60 minute programmable range and automatic shutdown
• Integrated sound-dampening lid to reduce airborne noise (typical SPL < 72 dB(A) at 1 m distance) and minimize solvent evaporation
• 320 W nominal ultrasonic power output delivered via high-Q piezoelectric transducers mounted on the tank bottom
• Robust control circuitry using industrial-grade ICs compliant with IEC 61000-4 immunity standards
• Manual fill-and-drain interface with integrated drain valve and ergonomic positioning for sink-line compatibility
• Standard stainless steel mesh basket included for sample suspension and protection against direct tank contact

Sample Compatibility & Compliance

The SCQ-5211D accommodates a broad range of non-porous and moderately porous substrates—including borosilicate glass, stainless steel, titanium alloys, ceramic filters, and anodized aluminum—provided they are compatible with the selected cleaning medium (e.g., deionized water, alkaline detergents, or low-volatility solvents such as isopropanol). It is not recommended for use with delicate MEMS devices, soft polymers (e.g., PDMS), or heat-sensitive biological samples unless validated per application-specific protocols. The unit conforms to electromagnetic compatibility requirements under EN 61000-6-3 (emission) and EN 61000-6-2 (immunity), and its construction meets material safety criteria outlined in ISO 10993-5 for short-term indirect contact with laboratory consumables. While not certified to GLP or GMP Annex 11, its digital timer log and mechanical repeatability support documentation of cleaning cycles for internal SOP compliance.

Software & Data Management

The SCQ-5211D features a dedicated microcontroller-based interface with no external software dependency. All operational parameters—including elapsed time and remaining cycle duration—are displayed on a high-contrast LED screen. No data export, remote monitoring, or audit trail functionality is provided; however, the timer’s deterministic behavior enables manual logging in laboratory notebooks or LIMS-integrated workflows. For regulated environments requiring traceability, users may integrate external timers or barcode-scanned cycle initiation logs to satisfy FDA 21 CFR Part 11 alignment when paired with documented procedures.

Applications

• Routine cleaning of volumetric flasks, burettes, syringes, and HPLC vials prior to calibration or analysis
• Preparation of metal coupons for corrosion testing or surface morphology studies (SEM/EDS sample prep)
• Removal of solder flux residues from PCB prototypes in electronics prototyping labs
• Cleaning of reusable filtration membranes and filter housings between sterilization cycles
• Decontamination of reusable pipette tips and centrifuge tubes in molecular biology workflows
• Supporting ASTM D2240 (durometer calibration) and ISO 12103-1 (test dust preparation) sample conditioning steps

FAQ

Is the SCQ-5211D suitable for cleaning delicate optical lenses?

No—this model lacks temperature control and frequency modulation required for fragile coated optics. Use only with uncoated fused silica or BK7 substrates immersed in low-surface-tension solvents, and limit exposure to ≤5 minutes.
Can I operate the unit continuously beyond 60 minutes?

No—the timer enforces a hard stop at 60 minutes to prevent transducer overheating. For extended cleaning, allow ≥15 minutes cooling interval between cycles.
Does the unit include heating capability?

No—SCQ-5211D is a non-heating model. For thermally enhanced cleaning, consider the SCQ-5211DH variant (available separately).
What maintenance is required for long-term reliability?

Transducer coupling integrity should be verified annually via impedance sweep testing; tank interior must be rinsed after each solvent use to prevent residue buildup.
Is the drain valve compatible with standard laboratory sink fittings?

Yes—the 1/2-inch NPT outlet accepts common rubber hose adapters and can be connected directly to floor drains or waste collection vessels.
