Ningbo Scientz SB25-12DTD Digital Ultrasonic Cleaner

Overview

The Ningbo Scientz SB25-12DTD is a digitally controlled, general-purpose ultrasonic cleaner engineered for reproducible, non-destructive cleaning of delicate and complex laboratory, industrial, and medical components. It operates on the principle of acoustic cavitation: high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers are transmitted through the cleaning medium—typically aqueous or solvent-based solutions—inducing transient microbubble formation and implosive collapse. This process generates localized pressure differentials exceeding 1000 atm and micro-jets with velocities up to 400 m/s, enabling effective removal of particulate contaminants, organic residues, biofilms, and adsorbed oils from surfaces, crevices, blind holes, and porous substrates without mechanical abrasion or thermal degradation. Designed for continuous operation in regulated environments, the SB25-12DTD complies with fundamental safety and electromagnetic compatibility requirements per IEC 61000-6-3 and IEC 61000-6-4, and its construction supports routine validation under GLP and ISO/IEC 17025-aligned quality systems.

Key Features

• Digital LED interface with real-time display of elapsed/remaining time and actual bath temperature (±1 °C accuracy)
• Adjustable ultrasonic power output (40–100% in 10% steps), enabling optimization for sensitive substrates or heavily soiled parts
• Precise temperature control from ambient to 80 °C, supporting enhanced solubilization of waxy or polymeric residues
• Programmable timer (1–999 minutes), with automatic shutdown and audible alert upon cycle completion
• Integrated sound-dampening lid with safety interlock—halts ultrasonic output when opened during operation
• Stainless steel tank (304 grade) with integrated drain valve and fill port for rapid solution exchange and maintenance
• Power parameter memory function: retains last-used settings (time, temperature, power level) after unexpected power interruption
• Robust transducer array mounted on the tank bottom, using high-reliability imported piezoceramics for long-term stability and uniform energy distribution

Sample Compatibility & Compliance

The SB25-12DTD accommodates a broad range of sample types and geometries within its 22.5 L tank (300 × 240 × 315 mm internal dimensions). Compatible materials include borosilicate glassware (vials, cuvettes, pipette tips), stainless steel surgical instruments, titanium dental tools, quartz optics, silicon wafers, precision bearings, fuel injector nozzles, and polymer-based microfluidic devices. The unit is routinely deployed in applications requiring adherence to ASTM D2603 (ultrasonic cleaning validation for metals), ISO 15883-1 (washer-disinfectors), and USP (analytical instrument qualification). While not certified as a medical device under FDA 510(k) or CE-MDD, its design enables integration into validated cleaning SOPs compliant with ISO 13485 and AAMI ST79. Users performing cleaning validation must establish parameters (e.g., frequency, dwell time, solution composition) per their specific load and contamination profile.

Software & Data Management

The SB25-12DTD operates via embedded firmware with no external software dependency. All operational parameters are stored in non-volatile memory and accessible via front-panel controls only—no USB, Ethernet, or cloud connectivity is provided. For laboratories requiring audit trails or electronic records, integration with external data loggers (e.g., calibrated thermocouple + timer inputs) is recommended to capture temperature/time profiles per FDA 21 CFR Part 11 Annex 11 principles. The unit does not generate raw acoustic data or waveform logs; however, its consistent 40 kHz output and stable power regulation support high inter-run reproducibility—critical for routine QC cleaning validation across batches.

Applications

• Cleaning of analytical labware prior to HPLC, ICP-MS, or trace elemental analysis to prevent carryover and background interference
• Pre-sterilization decontamination of reusable surgical instruments and endoscopes in hospital central sterile supply departments (CSSD)
• Removal of polishing compounds and oxide layers from optical lenses, prisms, and photomasks in semiconductor and photonics R&D
• De-gassing of mobile phases and solvents to eliminate bubble formation in liquid chromatography systems
• Cell lysis and homogenization of tissue samples in molecular biology workflows (when used with appropriate lysis buffers)
• Maintenance cleaning of precision metrology fixtures, gauge blocks, and calibration standards in metrology labs

FAQ

Is the SB25-12DTD suitable for cleaning delicate optics such as microscope objectives?

Yes—when operated at reduced power (40–60%) and with low-surface-tension, non-ionic detergent solutions, it effectively removes fingerprint oils and dust without damaging anti-reflective coatings.
Can this unit be used with flammable solvents like acetone or ethanol?

No—this model lacks explosion-proof certification and is rated for aqueous or mild aqueous-alcoholic solutions only. Solvent use requires intrinsically safe models with vapor extraction and thermal cutoffs.
Does the unit include a heater calibration certificate?

No—calibration is user-responsible. We recommend annual verification using a NIST-traceable PT100 probe and documented procedure per ISO/IEC 17025 Section 6.5.
What is the expected transducer service life under continuous daily use?

With proper maintenance (descaling every 200 hours, avoiding dry operation), the transducers maintain ≥95% nominal output for ≥5,000 operating hours.
Is remote monitoring or network control possible?

Not natively—the SB25-12DTD has no communication ports. Integration with building management systems requires third-party analog signal converters and custom PLC logic.
