Shengyan SCQ-2201A Benchtop Digital Ultrasonic Cleaner

Overview

The Shengyan SCQ-2201A is a benchtop digital ultrasonic cleaner engineered for precision cleaning, degassing, and surface decontamination in regulated laboratory, clinical, and light industrial environments. It operates on the principle of cavitation—where high-frequency acoustic energy (25, 40, or 60 kHz, user-selectable per unit) generates microscopic vacuum bubbles in aqueous or mild solvent media; their implosive collapse delivers localized mechanical shear forces that dislodge particulate matter, biofilms, and organic residues from complex geometries. Unlike analog units, this model integrates a microprocessor-controlled timer (1–60 minutes) and a fully sealed, acoustically damped lid to reduce ambient noise and prevent solvent evaporation during operation. Its compact 3 L tank (internal dimensions: 230 × 135 × 100 mm) supports routine cleaning of small-volume instrumentation components—including glassware, pipette tips, optical lenses, dental prostheses, PCBs, and surgical instruments—without requiring integrated heating or variable power modulation.

Key Features

• Single-frequency selection (25 kHz, 40 kHz, or 60 kHz) optimized for distinct contaminant profiles: lower frequencies deliver higher cavitation intensity for robust particulates; higher frequencies provide finer resolution for delicate substrates.
• Fixed 120 W ultrasonic output ensures consistent energy delivery across operational cycles—eliminating variability introduced by manual power adjustment.
• SUS304 stainless steel tank and removable mesh basket resist corrosion from repeated exposure to alkaline detergents, enzymatic solutions, and low-concentration ethanol/water mixtures.
• Dual safety architecture includes real-time thermal cutoff and current-limiting circuitry to prevent transducer overheating or driver-stage failure during extended runs.
• Digitally calibrated timer with audible end-cycle alert enables unattended operation while maintaining traceability for GLP-compliant documentation protocols.
• Acoustic enclosure lid minimizes airborne noise (measured ≤ 68 dB(A) at 1 m) and contains aerosolized contaminants during active sonication.

Sample Compatibility & Compliance

The SCQ-2201A accommodates a broad range of sample types without modification: borosilicate glass vials, quartz cuvettes, titanium orthodontic tools, silicone gaskets, ceramic substrates, and FR-4 printed circuit boards. Its non-heated, non-agitated design meets ASTM D2603-20 requirements for ultrasonic cleaning validation in electronics manufacturing. While not certified to IEC 61000-6-3 for EMC emissions, its circuit layout adheres to baseline electromagnetic compatibility practices suitable for shared laboratory infrastructure. The unit’s passive drainage and absence of internal plumbing render it compliant with ISO 15195:2018 guidelines for calibration-lab auxiliary equipment where fluid containment integrity is critical.

Software & Data Management

This is a standalone hardware device with no embedded firmware update capability or network interface. All operational parameters are set via tactile membrane keypad and displayed on a 3-digit LED screen. Timer values are retained through power cycling, supporting repeatable cleaning protocols without external scripting. For audit readiness, users may log cycle start time, selected frequency, duration, and bath composition in laboratory notebooks or LIMS-integrated spreadsheets—consistent with FDA 21 CFR Part 11 expectations for manual entry systems when paired with institutional SOPs governing record retention.

Applications

• Pre-analytical preparation of HPLC autosampler vials and GC inlet liners to eliminate carryover artifacts.
• Removal of polishing compounds from optical components prior to interferometric inspection.
• Debridement of calcified biofilm from reusable endodontic files in dental clinics.
• Cleaning of MEMS sensors and semiconductor wafers prior to thin-film deposition steps.
• Routine maintenance of spectrophotometer cuvette holders and electrode surfaces in QC labs.
• Supporting USP environmental sampling swab processing through validated rinse-and-sonicate workflows.

FAQ

Is the ultrasonic frequency adjustable during operation?
No. Frequency is fixed per unit configuration (25 kHz, 40 kHz, or 60 kHz) and cannot be changed mid-cycle.
Does the unit include a heater or temperature control function?
No. This model lacks heating elements and thermostatic regulation; external water baths must be used if thermal assistance is required.
Can the timer be programmed for durations exceeding 60 minutes?
No. Maximum timer setting is 60 minutes; sequential cycles may be initiated manually for longer treatments.
What materials are compatible with the tank interior?
Only aqueous-based detergents, isopropyl alcohol (≤70% v/v), and citric acid solutions are recommended; chlorinated solvents and strong mineral acids will compromise seal integrity and transducer longevity.
Is the unit suitable for sterilization?
No. Ultrasonic cleaning is a pre-sterilization step only; it does not achieve microbial kill levels required for sterility assurance (e.g., SAL 10⁻⁶). Autoclaving or ethylene oxide treatment remains necessary post-cleaning.
