Overview
The Ningbo Scientz SB25-12D is a general-purpose digital ultrasonic cleaner engineered for consistent, non-invasive cleaning of delicate and precision-sensitive components in research laboratories, quality control environments, and industrial maintenance settings. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy is transmitted into the cleaning medium via piezoelectric transducers bonded to the stainless-steel tank bottom. This generates controlled microbubble formation and implosive collapse within the liquid, producing localized shear forces, microstreaming, and transient high temperatures—mechanisms that effectively dislodge particulate contaminants, organic residues, oils, and biofilms without mechanical abrasion or surface damage. Designed for reliability in continuous operation, the SB25-12D delivers reproducible cleaning performance across diverse sample geometries and material classes—including glassware, metal parts, optical elements, and medical instruments—making it a foundational tool in sample preparation workflows governed by ISO 13485, ASTM D4489, and CLSI GP26-A4 standards.
Key Features
- Digital timer with precise 1–600 minute range and real-time countdown display for repeatable process control
- Stainless-steel tank (22.5 L capacity) and exterior housing for corrosion resistance and long-term structural integrity
- Integrated sound-dampening lid to reduce ambient noise and prevent solvent evaporation during operation
- Standard drain and fill fittings enabling rapid solution exchange and compatibility with deionized water, aqueous detergents, or low-toxicity solvents
- Non-adjustable but optimized 40 kHz frequency—selected for balanced penetration depth and cavitation intensity across common lab substrates
- Fixed-power output options: 600 W standard or 720 W high-output configuration (model-dependent), ensuring stable energy delivery without duty-cycle modulation
- Automatic shutdown with power-loss memory function: resumes last-set timer value upon power restoration, supporting GLP-compliant documentation practices
Sample Compatibility & Compliance
The SB25-12D accommodates a broad spectrum of laboratory and industrial specimens: borosilicate glassware (vials, cuvettes, pipette tips), stainless-steel surgical tools, titanium dental implants, quartz optics, MEMS components, and jewelry-grade metals and gemstones. Its fixed-frequency, fixed-power architecture ensures predictable cleaning kinetics—critical for validation protocols under FDA 21 CFR Part 11 (when integrated with compliant data logging systems) and ISO 17025-accredited calibration frameworks. While the unit itself does not provide temperature regulation or programmable power ramping, its mechanical robustness and consistent acoustic output support routine use in GMP-aligned cleanrooms when paired with validated cleaning agents and documented SOPs.
Software & Data Management
The SB25-12D is a standalone hardware platform with no embedded software or network interface. All operational parameters are set via front-panel membrane keys and displayed on a high-contrast LED screen. Timer values, elapsed time, and power status are retained in non-volatile memory. For traceability in regulated environments, users may integrate external time-stamped video recording, manual logbooks, or third-party environmental monitoring systems. The device complies with IEC 61000-6-3 (EMC emissions) and IEC 61010-1 (safety requirements for laboratory equipment), and its construction meets RoHS Directive 2011/65/EU restrictions on hazardous substances.
Applications
- Routine decontamination of volumetric flasks, centrifuge tubes, and HPLC sample vials prior to analytical use
- Pre-analytical degassing of mobile phases and buffer solutions to eliminate air bubbles affecting chromatographic baseline stability
- Surface preparation of optical lenses and laser components prior to coating or metrology
- Cleaning of endodontic files, orthodontic brackets, and implant abutments in dental laboratories per ADA Specification No. 117
- Removal of machining coolants and fine metal particulates from precision bearings and fuel injectors in R&D prototyping
- Assisted cell lysis and nanoparticle dispersion in early-stage formulation development (as a pre-step before sonication with probe-type systems)
FAQ
Does the SB25-12D support temperature control or heating?
No. This model lacks a built-in heater or temperature sensor; it is designed for ambient-temperature ultrasonic cleaning only.
Can the ultrasonic power be adjusted during operation?
No. Power output is fixed at either 600 W or 720 W (depending on configuration); no variable amplitude or duty-cycle control is provided.
Is the unit compatible with organic solvents such as acetone or isopropanol?
Yes—provided appropriate ventilation and explosion-proof precautions are observed. Consult solvent compatibility charts for 304 stainless steel and confirm transducer bonding integrity with prolonged exposure.
What maintenance is required for long-term reliability?
Routine inspection of tank integrity, periodic descaling with mild acidic solutions (e.g., 5% citric acid), and verification of transducer adhesion every 12 months under heavy-use conditions.
Does the SB25-12D meet international safety certifications?
Yes—it carries CE marking per EU Machinery Directive 2006/42/EC and complies with IEC 61010-1:2010 for electrical safety in laboratory equipment.
