Shengyan SCQ-8201H Split-Type Ultrasonic Cleaner

Overview

The Shengyan SCQ-8201H Split-Type Ultrasonic Cleaner is an industrial-grade, benchtop-compatible cleaning system engineered for high-efficiency particulate and organic contaminant removal from precision components, laboratory glassware, medical instruments, and semiconductor substrates. It operates on the principle of cavitation-induced mechanical energy transfer: at a fixed frequency of 20 kHz, high-intensity acoustic waves generate transient microbubbles in the cleaning solution that collapse violently near solid surfaces—producing localized shockwaves, microstreaming, and intense shear forces. This physical mechanism enables effective removal of sub-micron residues without chemical abrasion or thermal degradation. Designed for sustained operation in QC labs, R&D facilities, and production cleanrooms, the SCQ-8201H features a modular split architecture—separating the ultrasonic generator from the tank assembly—to optimize heat dissipation, simplify maintenance, and enhance electromagnetic compatibility in sensitive instrumentation environments.

Key Features

• Robust 22.5 L cleaning tank fabricated from 2.0 mm-thick SUS304 stainless steel, ensuring long-term corrosion resistance against alkaline, acidic, and aqueous cleaning solutions.
• Dedicated 1440 W ultrasonic output delivered via 24 high-reliability piezoelectric transducers (60 W each), mounted on the tank bottom for uniform energy distribution and minimized standing-wave interference.
• Precise digital timer (1–600 minutes) with auto-shutdown function, supporting repeatable process validation under defined cleaning protocols.
• Integrated heating system with PID-controlled temperature regulation from ambient to 80 °C—enabling thermally assisted cleaning for waxy, greasy, or polymer-based contaminants.
• Acoustically damped hinged lid minimizes airborne noise emission (<75 dB(A) at 1 m) and prevents solvent evaporation during heated operation.
• Manual fill-and-drain configuration with rear-mounted drain valve facilitates safe handling of hazardous or regulated cleaning media under local exhaust or fume hood conditions.
• Generator-tower design isolates high-voltage electronics from the wet environment, reducing moisture ingress risk and extending service life in high-humidity laboratories.

Sample Compatibility & Compliance

The SCQ-8201H accommodates a broad range of sample geometries—including beakers, Petri dishes, syringe filters, surgical tools, optical lenses, and printed circuit boards—within its 500 × 300 × 150 mm internal chamber. Its non-aggressive, non-contact cleaning action preserves dimensional integrity and surface finish of delicate substrates. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the system supports documentation-ready operation when integrated into validated cleaning SOPs compliant with ISO 15883-1 (washer-disinfectors), ASTM D2603 (ultrasonic cleaning performance testing), and USP (cleaning validation for pharmaceutical equipment). Optional calibration certificates for temperature and timer accuracy are available upon request for GLP/GMP-aligned workflows.

Software & Data Management

The SCQ-8201H operates via an embedded digital control panel with LED display—no external software or PC interface is required. All operational parameters (time, temperature, and power activation status) are logged locally in non-volatile memory with timestamped entries, supporting basic audit trails for routine QA verification. For facilities requiring electronic record retention, third-party data loggers can be connected via analog voltage outputs (0–5 V) corresponding to real-time temperature and timer countdown signals. The absence of network connectivity ensures immunity to cybersecurity vulnerabilities—a critical consideration for regulated lab environments.

Applications

• Pre-analytical cleaning of HPLC vials, autosampler needles, and ICP-MS sample introduction components to eliminate trace metal carryover.
• Decontamination of reusable surgical instruments prior to sterilization in accordance with AAMI ST79 guidelines.
• Removal of photoresist residues and etch byproducts from silicon wafers and MEMS devices in microfabrication cleanrooms.
• Routine cleaning of electron microscopy grids, TEM holders, and AFM probes to prevent imaging artifacts.
• Extraction support for environmental analysis—e.g., PCBs from soil matrices or PAHs from sediment samples—via ultrasonically accelerated solvent leaching.

FAQ

Is the ultrasonic frequency adjustable?
No. The SCQ-8201H operates exclusively at 20 kHz, optimized for high-power macro-cavitation suitable for heavy-duty cleaning tasks.
Can the unit be integrated into automated lab workflows?
Not natively. It lacks RS-232, Ethernet, or PLC-compatible I/O ports; however, external relay control of power-on/off and timer start/stop is possible using dry-contact inputs.
What is the expected transducer service life under continuous operation?
Rated for ≥10,000 hours of cumulative operation when operated within specified temperature and duty-cycle limits (≤80 °C liquid temperature, ≤50% duty cycle for extended runs).
Does the system include a degassing function?
No dedicated degas mode is provided. Users should manually deaerate the cleaning solution by operating the unit at room temperature for 5–10 minutes before initiating heated or timed cycles.
Is validation documentation available for IQ/OQ/PQ protocols?
Yes—Shengyan provides template test protocols and blank calibration logs. Full qualification support requires collaboration with the customer’s validation team and may involve third-party metrology services for temperature uniformity mapping and cavitation intensity profiling.
