Overview
The Ningbo Scientz SBL-108DT is a high-capacity, temperature-controlled benchtop ultrasonic cleaner engineered for reproducible, non-destructive cleaning of delicate and complex components across research laboratories, quality control facilities, and regulated manufacturing environments. It operates on the principle of acoustic cavitation: piezoelectric transducers convert high-frequency electrical energy (40 kHz) into mechanical vibrations transmitted through the stainless-steel tank wall into the cleaning medium. These vibrations generate transient microbubbles that grow and collapse violently—producing localized pressures exceeding 1000 atm and liquid-phase jet streams up to 400 m/s. This hydrodynamic shear effect efficiently removes particulate contaminants, organic residues (e.g., oils, greases, proteins), and biofilms from surfaces—including recessed features, blind holes, microchannels, and porous substrates—without mechanical abrasion or thermal degradation. Unlike fixed-power units, the SBL-108DT integrates closed-loop temperature regulation and digitally modulated ultrasonic output, enabling process standardization critical for GLP-compliant cleaning validation and ASTM F312-22 (Standard Test Methods for Cleaning Verification).
Key Features
- 108-liter capacity stainless-steel tank (304 grade) with reinforced corner welds and integrated transducer mounting for uniform energy distribution
- Precise temperature control from 5 °C to 80 °C via dual-mode thermal management: resistive heating element + thermoelectric (Peltier) cooling module
- Digitally adjustable ultrasonic power output (1–99% in 1% increments), supporting optimization for sensitive substrates (e.g., optical lenses, MEMS devices)
- Programmable timer with 1–9999 minute resolution; supports multi-step protocols (e.g., pre-rinse → main clean → post-rinse)
- Motorized, acoustically damped lid with safety interlock—automatically halts ultrasonics upon lid opening per IEC 61000-6-4 EMC and EN 61000-3-2 harmonic compliance
- Touchscreen HMI with real-time display of elapsed time, setpoint vs. actual temperature, and active power level
- Power interruption recovery: retains all user-defined parameters (temperature, time, power) after AC loss and resumes operation upon restoration
Sample Compatibility & Compliance
The SBL-108DT accommodates a broad range of sample geometries and material classes: glassware (volumetric flasks, cuvettes, NMR tubes), polymer-based consumables (centrifuge tubes, microplates), metal components (precision bearings, fuel injectors), medical instruments (endoscopic channels, dental scalers), and optoelectronic assemblies (lens mounts, sensor housings). Its cleaning efficacy has been validated against ISO 15883-5 for washer-disinfector performance and aligns with USP guidelines for cleaning verification of laboratory equipment. The system supports audit-ready documentation when paired with optional RS-232/RS-485 or Ethernet interfaces for integration into LabVantage or Thermo Fisher SampleManager LIMS platforms.
Software & Data Management
The embedded firmware supports CSV export of operational logs (timestamp, setpoints, actual values, fault codes) via USB host port. Optional Scientz ControlSuite™ software (Windows-based) enables remote configuration, protocol library management, and electronic signature–enabled batch record generation compliant with FDA 21 CFR Part 11 requirements. All parameter changes are timestamped and logged with operator ID (when network-authenticated), satisfying ALCOA+ data integrity principles for GMP-regulated labs.
Applications
- Cleaning of analytical glassware prior to trace-metal analysis (e.g., ICP-MS, AAS) to eliminate carryover contamination
- De-gassing of HPLC mobile phases and cell culture media to prevent pump cavitation and bubble-induced detector noise
- Preparation of nanoparticle suspensions via ultrasonic dispersion in solvent matrices
- Surface preparation of semiconductor wafers and photomasks prior to lithography
- Restoration of antique optics and museum-grade artifacts without solvent exposure
- Validation of cleaning processes per ASTM E2997-21 (Standard Practice for Determining Cleaning Effectiveness Using Surface Analysis)
FAQ
What is the maximum recommended operating temperature for aqueous cleaning solutions?
The system is rated for continuous operation at 80 °C with water-based detergents meeting ASTM D4169 stability criteria. For solvent-based media, consult material compatibility charts and observe flash-point safety limits.
Can the unit be integrated into a centralized lab automation network?
Yes—via Modbus RTU over RS-485 or TCP/IP (optional Ethernet module), enabling status polling, command execution, and alarm forwarding to BMS or SCADA systems.
Is calibration traceable to national standards?
Temperature sensors are factory-calibrated against NIST-traceable references; users may perform field verification using Class A PT100 probes per ISO/IEC 17025 requirements.
Does the system meet international electrical safety standards?
It complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking under the EU Low Voltage and EMC Directives.
