Ningbo Scientz DTY Series Quiet Ultrasonic Cleaner

Overview

The Ningbo Scientz DTY 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 mechanical vibrations (40 kHz) generated by piezoelectric transducers are transmitted through liquid media, inducing rapid formation and collapse of microscopic vapor cavities. This implosive action produces localized shockwaves and microstreaming—mechanical forces sufficient to dislodge particulate contaminants, organic residues, and adsorbed films from complex geometries including blind holes, microchannels, and porous surfaces—without mechanical abrasion or thermal degradation. Designed specifically for noise-sensitive applications—including analytical labs adjacent to offices, cleanrooms, dental clinics, and optical assembly areas—the DTY Series integrates structural acoustics and power electronics to achieve sustained operation below 55 dB(A), verified per ISO 3744-compliant third-party testing accredited by CNAS.

Key Features

• Acoustic Noise Suppression: Triple-layer sound-absorbing insulation lining the tank chamber and lid, combined with vibration-isolated transducer mounting and hydraulic-assisted lid actuation, ensures stable operation at ≤55 dB(A) at 1 m distance—meeting stringent occupational health requirements under OSHA 29 CFR 1910.95 and EU Directive 2003/10/EC.
• Intuitive Touch Interface: A 7-inch full-color capacitive touchscreen provides real-time visualization of temperature, time, power level, frequency status, and operational mode; supports multi-language UI (English, German, French, Spanish) and user-defined protocol storage.
• Multi-Frequency Flexibility: While optimized for 40 kHz (ideal for general-purpose cleaning and degassing), select DTY models support programmable frequency switching between 28 kHz, 40 kHz, and 80 kHz—enabling tailored energy delivery for delicate optics (higher frequency) versus heavy particulate removal (lower frequency).
• Robust Generator Architecture: Self-excited ultrasonic generator with digital auto-frequency tracking maintains resonance stability across load variations (e.g., changing liquid levels or viscosity); incorporates over-temperature, over-current, and short-circuit protection plus non-volatile memory for power-loss recovery.
• High-Efficiency Transduction: Zirconium-titanium-lead (PZT) ceramic transducers with Q-factor >1,200 ensure >92% electroacoustic conversion efficiency—minimizing heat generation while maximizing cavitation density in the cleaning bath.
• Seamless 304 Stainless Steel Tank: Deep-drawn monolithic construction eliminates weld seams and crevices—critical for GMP-compliant cleaning validation and residue-free processing of pharmaceutical tools, surgical instruments, and semiconductor wafers.

Sample Compatibility & Compliance

The DTY Series accommodates a broad range of substrates and sample types without surface damage: borosilicate glassware (vials, cuvettes, chromatography columns), stainless-steel surgical tools, titanium dental implants, sapphire watch components, fused silica optics, and polymer microfluidic chips. Its temperature control (ambient to 80 °C) and adjustable power (0–100%) enable optimization per material sensitivity—e.g., low-power/low-temperature cycles for protein-coated surfaces, higher-energy protocols for carbonized metal parts. The system complies with IEC 61000-6-3 (EMC emission limits), UL 61010-1 (safety), and supports IQ/OQ documentation packages aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements for electronic records and signatures.

Software & Data Management

Built-in firmware supports GLP/GMP audit trails: all parameter changes, start/stop events, and error logs are timestamped and stored internally (≥10,000 entries). Optional USB export enables traceable data transfer to LIMS or ELN platforms. Remote monitoring via RS-232 or optional Ethernet module allows integration into centralized lab automation systems. Protocol libraries can be password-protected and assigned to user roles—supporting multi-departmental deployment in QC laboratories subject to ISO/IEC 17025 accreditation.

Applications

• Cleaning of HPLC vials, pipette tips, centrifuge tubes, and filtration membranes prior to trace analysis;
• Degassing of mobile phases and solvents to prevent pump cavitation and baseline drift in LC-MS systems;
• Preparation of nanoparticle suspensions and liposome formulations via controlled cavitation-induced dispersion;
• Decontamination of reusable endoscopes, orthodontic instruments, and implantable device carriers in accordance with AAMI ST91 and ISO 15883;
• Removal of polishing compounds and hydrophobic films from microscope objectives, interferometric mirrors, and laser optics;
• Surface activation of polymeric substrates prior to coating or bonding in microfabrication workflows.

FAQ

Is the DTY Series compliant with international safety and electromagnetic compatibility standards?
Yes. Certified to IEC 61000-6-3 (EMI), IEC 61000-6-1 (EMS), and UL 61010-1. CE marking is provided with Declaration of Conformity.
Can cleaning parameters be validated and re-executed identically across multiple units?
Yes. Each unit stores up to 99 user-defined protocols with full parameter locking; optional calibration certificate includes verification of temperature accuracy (±0.5 °C) and timer deviation (<±0.1%).
Does the system support automated liquid handling integration?
Standard RS-232 interface enables bidirectional communication with external controllers; optional Ethernet module supports Modbus TCP and HTTP API for integration into LabVantage or STARLIMS.
What maintenance is required to sustain acoustic performance over time?
Annual inspection of transducer adhesion integrity and generator output waveform fidelity is recommended; no routine consumables are required beyond periodic tank cleaning with mild detergent.
Is the noise rating measured per standardized methodology?
Yes—third-party CNAS-accredited test report (certification number available upon request) follows ISO 3744:2010 using calibrated Class 1 sound level meter at 1 m distance, 1.5 m height, in semi-anechoic conditions.
