Overview
The Ningbo Scientz SB25-12DT is a digitally controlled, heating-capable ultrasonic cleaner engineered for reproducible, high-efficiency cleaning and auxiliary laboratory processes in research, quality control, and production environments. 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 base. This generates transient microbubbles that grow and collapse violently under alternating pressure cycles—producing localized shockwaves, microstreaming, and intense shear forces at solid–liquid interfaces. These physical phenomena enable effective removal of particulate contaminants, organic residues, biofilms, and adsorbed oils from complex geometries—including blind holes, narrow lumens, and textured surfaces—without mechanical abrasion or surface damage. Unlike non-heating units, the SB25-12DT integrates precise thermostatic control (ambient to 80 °C), which enhances solubilization kinetics of hydrophobic soils and improves cleaning efficacy for waxy, greasy, or polymeric residues.
Key Features
- 22.5-liter stainless-steel tank (304 grade) with reinforced corners and seamless construction for long-term corrosion resistance and structural integrity
- Digital microprocessor-based controller with dual LED display showing real-time temperature and remaining timer duration
- Adjustable heating function with ±1 °C accuracy across 0–80 °C range; automatic overtemperature cutoff at 90 °C for safety compliance
- Programmable timer (1–99 minutes) with auto-shutdown and power-failure memory retention—preserves last-set parameters after interruption
- Integrated sound-dampening lid with ergonomic handle and viewing window, reducing ambient noise to ≤65 dB(A) at 1 m distance
- Standard drain valve and fill port for rapid liquid exchange; compatible with deionized water, aqueous detergents, and low-volatility solvents
- Overcurrent protection, short-circuit protection, and thermal fuse safeguarding for continuous unattended operation
Sample Compatibility & Compliance
The SB25-12DT accommodates a broad spectrum of labware and industrial components, including borosilicate glassware (vials, cuvettes, pipette tips), polymer-based consumables (centrifuge tubes, microplates), metal parts (surgical instruments, watch mechanisms, fuel injectors), optical elements (lens assemblies, quartz cuvettes), and delicate jewelry. Its cleaning performance aligns with ASTM D2607 (Standard Practice for Ultrasonic Cleaning of Metal Parts) and supports GLP/GMP workflows requiring documented process consistency. While not certified as a medical device sterilizer per ISO 17664 or EN 13060, it serves as a validated pre-cleaning step prior to autoclaving or ethylene oxide treatment in regulated healthcare settings. All electrical components meet CE and RoHS directives; tank materials comply with USP Class VI biocompatibility requirements for indirect contact applications.
Software & Data Management
The SB25-12DT is a standalone instrument without external software connectivity or data export capability. However, its embedded firmware provides audit-ready operational traceability: all parameter changes—including time, temperature, and start/stop events—are logged internally with timestamp resolution to the nearest minute. The digital interface supports manual calibration verification of temperature sensors using NIST-traceable reference thermometers. For laboratories operating under FDA 21 CFR Part 11 or Annex 11 requirements, optional third-party data loggers (e.g., HOBO UX100 series) may be deployed externally to record tank temperature and cycle duration, enabling full electronic record generation and signature support when integrated into validated LIMS or ELN systems.
Applications
- Routine decontamination of analytical glassware and plastic labware prior to HPLC, GC, or spectroscopic analysis
- Removal of residual proteins, nucleic acids, or cell debris from reusable electrophoresis combs, gel trays, and sonication probes
- Preparation of homogeneous suspensions for nanoparticle characterization (DLS, TEM sample prep)
- Accelerated solvent extraction of plant metabolites, soil-bound pollutants, or pharmaceutical actives in R&D labs
- Deaeration of mobile phases and buffer solutions to prevent pump cavitation and baseline drift in chromatographic systems
- Cleaning of precision optics, MEMS devices, and semiconductor wafers where particle-free surfaces are critical
FAQ
Is the ultrasonic power output adjustable?
No—the SB25-12DT delivers a fixed 600 W nominal acoustic power at 40 kHz, optimized for uniform energy distribution across the 22.5 L tank volume.
Can this unit be used with flammable solvents?
Not recommended. The heater and internal electronics are not explosion-proof; only aqueous or high-flashpoint (>60 °C) solvents should be used.
What is the maximum allowable liquid level in the tank?
Fill level must remain between 10 L (minimum operational volume) and 20 L (maximum safe fill line) to ensure optimal cavitation field formation and transducer cooling.
Does the unit include a degassing mode?
Yes—running the device empty for 5–10 minutes at room temperature effectively removes dissolved air from fresh cleaning solution before use.
How often should the transducers be serviced or replaced?
Under normal usage (≤8 hrs/day, proper maintenance), piezoelectric transducers retain >95% efficiency for ≥5 years; no scheduled replacement is specified by the manufacturer.
