Overview
The Ningbo Scientz DTS Series Quiet Ultrasonic Cleaner is an engineered solution for precision cleaning, degassing, emulsification, dispersion, and sample homogenization in regulated laboratory and industrial environments. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy is converted into mechanical vibrations via piezoelectric transducers bonded to the stainless-steel tank wall. These vibrations propagate through the cleaning medium—typically aqueous or solvent-based solutions—inducing transient microbubble formation and violent implosive collapse. The resulting localized shockwaves and microstreaming generate shear forces sufficient to dislodge particulate contaminants, organic residues, and biofilms from complex geometries—including blind holes, capillary channels, and microstructured surfaces—without mechanical abrasion or thermal degradation.
Unlike conventional ultrasonic cleaners, the DTS Series integrates a comprehensive noise-mitigation architecture. Its three-dimensional acoustic insulation system—comprising multi-layer eco-acoustic damping foam bonded to internal tank walls and structural reinforcements—reduces operational sound pressure levels to <55 dB(A), verified per ISO 3744:2010 by CNAS-accredited third-party laboratories. This enables continuous operation in shared lab spaces, QC suites, and cleanroom-adjacent preparation areas without compromising auditory comfort or regulatory compliance with occupational health standards (e.g., OSHA 29 CFR 1910.95).
Key Features
- Acoustically Optimized Design: Integrated sound-dampening lid with hydraulic gas-strut assist ensures smooth, quiet opening/closing while maintaining consistent cavity sealing during operation.
- High-Efficiency Transduction: PZT-based transducers with high electromechanical coupling coefficient (kp) and Q-factor deliver superior energy transfer efficiency (>85% electroacoustic conversion) and extended service life under variable load conditions.
- Intelligent Generator System: Self-excited solid-state ultrasonic generator with real-time frequency tracking, over-current/over-temperature protection, and power-loss memory retention ensures stable output across fluid level changes and temperature gradients.
- Full Parameter Programmability: Touchscreen interface supports independent configuration of ultrasonic duration (1–999 min), power intensity (0–100% in 1% increments), and heating setpoint (ambient to 80 °C ±1 °C).
- Corrosion-Resistant Construction: Seamless one-piece 304 stainless-steel tank fabricated via deep-drawing process eliminates weld seams and crevices—preventing residue accumulation and facilitating ISO 13485-aligned cleaning validation.
- Dual-Mode Operation: Switchable ultrasonic cleaning and degassing modes optimize energy delivery for either contaminant removal or dissolved-gas elimination in solvents and reagents.
Sample Compatibility & Compliance
The DTS Series accommodates a broad range of sample types and containers, including glassware (vials, flasks, cuvettes), polymer-based consumables (centrifuge tubes, microplates), metallic components (surgical instruments, dental tools, optical mounts), and delicate substrates (quartz optics, MEMS devices). Its non-contact cleaning mechanism preserves surface integrity—critical for applications requiring trace-metal-free processing or low-particulate environments (ISO Class 5–7). The unit complies with IEC 61000-6-3 (EMC emission limits) and meets CE marking requirements for laboratory equipment safety (EN 61010-1:2010). Optional documentation packages support GLP/GMP workflows, including factory calibration certificates, IQ/OQ protocols, and audit-ready electronic logs compatible with FDA 21 CFR Part 11-compliant data management systems.
Software & Data Management
The full-color capacitive touchscreen provides intuitive navigation and real-time visualization of all active parameters: elapsed time, current temperature, applied power percentage, and operational mode status. All user-defined programs are stored in non-volatile memory with timestamped execution history. While the base firmware does not include remote connectivity, the RS-232 port enables integration with centralized lab information systems (LIMS) or programmable logic controllers (PLCs) for automated batch logging and SOP enforcement. Audit trails record parameter modifications, start/stop events, and fault alerts—supporting traceability requirements under ISO/IEC 17025 and CAP accreditation frameworks.
Applications
- Life Sciences: Cleaning of pipette tips, PCR plates, electrophoresis combs, and cell culture flasks; degassing of cell culture media and HPLC mobile phases.
- Clinical Diagnostics & Dentistry: Decontamination of reusable endodontic files, orthodontic brackets, and surgical handpieces per ANSI/AAMI ST91:2023 guidelines.
- Materials Science: Removal of polishing compounds from metallographic specimens; dispersion of nanomaterials in colloidal suspensions.
- Optics & Precision Engineering: Particle-free cleaning of microscope objectives, laser optics, and semiconductor wafer carriers.
- Jewelry & Watchmaking: Non-abrasive restoration of fine gold, platinum, and gemstone settings without micro-scratching or alloy leaching.
FAQ
Is the DTS Series suitable for use with flammable solvents?
Yes—when operated in degassing mode without heating, and with proper ventilation and explosion-proof auxiliary equipment per NFPA 30 and ATEX Directive 2014/34/EU.
Can multiple tanks be synchronized for parallel operation?
No—the DTS Series is a standalone unit; however, identical models can be operated independently using identical program settings for reproducible inter-unit comparability.
What maintenance is required for long-term reliability?
Routine inspection of transducer bonding integrity, periodic descaling of the tank interior using citric acid solution, and annual verification of temperature sensor accuracy against NIST-traceable references.
Does the unit support validation documentation for regulated environments?
Yes—Scientz provides optional IQ/OQ documentation kits, calibration records, and CNAS-verified acoustic performance reports upon request.
How does the automatic frequency tracking improve cleaning consistency?
It continuously monitors resonant frequency drift caused by temperature rise or fluid composition changes, dynamically adjusting drive frequency to maintain optimal cavitation intensity and prevent transducer detuning-induced efficiency loss.
