Overview
The Ningbo Scientz SBL-22DT is a benchtop ultrasonic cleaner engineered for reproducible, non-invasive cleaning of delicate and complex laboratory components. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy is transmitted into an aqueous or solvent-based cleaning bath via piezoelectric transducers bonded to the tank bottom. This generates controlled microbubble formation and implosive collapse—producing localized transient pressures exceeding 1000 atm and liquid jet velocities >400 m/s—capable of dislodging sub-micron particulates, organic residues, biofilms, and adsorbed hydrocarbons from recessed geometries including capillary bores, threaded fittings, and porous surfaces. Unlike abrasive or thermal methods, cavitation-based cleaning preserves surface integrity while achieving superior penetration in blind holes and microfluidic channels. The unit integrates a thermostatically regulated heating system (up to 80 °C), enabling temperature-assisted solubilization of waxy or viscous contaminants without compromising transducer longevity or bath stability.
Key Features
- Stainless steel 304 tank (22 L capacity) with reinforced welds and corrosion-resistant finish for long-term compatibility with aqueous detergents, alcohols, and mild alkaline solutions
- Digital touch interface with real-time display of elapsed time, set temperature, and actual bath temperature (±0.5 °C accuracy)
- Precision temperature control (ambient to 80 °C) using PID-regulated immersion heaters; optional cooling module available for low-temperature applications (down to 5 °C)
- Integrated sound-dampening lid with safety interlock—meets IEC 61000-6-3 emission limits for laboratory electromagnetic compatibility
- Drain valve and fill port located at tank base for rapid fluid exchange and residue-free maintenance
- Power-fail memory function retains user-defined parameters (time, temperature) after unexpected shutdown—supports GLP-compliant workflow continuity
Sample Compatibility & Compliance
The SBL-22DT accommodates standard laboratory glassware (e.g., volumetric flasks, centrifuge tubes, HPLC vials), metal components (stainless steel surgical instruments, precision bearings), optical substrates (microscope slides, quartz cuvettes), and polymer-based devices (PDMS microchips, 3D-printed fixtures). Its cleaning efficacy has been validated per ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricants) and ISO 13485 Annex A for medical device reprocessing validation protocols. While not certified as a sterilizer, the unit supports pre-sterilization cleaning steps compliant with AAMI ST79:2017 guidelines when used with validated enzymatic or alkaline formulations. All electrical components conform to CE marking requirements (EN 61010-1) and RoHS Directive 2011/65/EU.
Software & Data Management
The SBL-22DT operates as a standalone instrument with no embedded firmware or network connectivity. All operational parameters are stored locally in non-volatile memory. For audit-trail compliance in regulated environments (e.g., pharmaceutical QC labs), users may integrate external data loggers via RS-232 or analog output (0–5 V) for continuous recording of bath temperature and timer status. The device supports 21 CFR Part 11–compliant documentation workflows when paired with validated electronic lab notebook (ELN) systems—no proprietary software installation required.
Applications
- Routine decontamination of glassware and plastic consumables prior to analytical use (e.g., trace-metal analysis, cell culture)
- Removal of residual photoresist, flux, or solder paste from PCBs and MEMS components
- Preparation of TEM grids and AFM cantilevers by eliminating hydrocarbon contamination
- Deagglomeration and dispersion of nanomaterials (e.g., carbon nanotubes, metal oxides) in suspension media
- Ultrasonic degassing of mobile phases for HPLC and UHPLC systems to prevent pump cavitation and detector noise
- Supporting USP and compounding standards through validated cleaning of isolator gloves and tooling surfaces
FAQ
What cleaning solutions are compatible with the SBL-22DT?
Aqueous alkaline detergents (pH 9–11), ethanol/water mixtures (≤70%), and low-foaming enzymatic formulations are recommended. Avoid halogenated solvents, strong acids (e.g., concentrated HNO₃), or undiluted acetone due to transducer degradation risk.
Can the unit operate continuously for extended periods?
Yes—designed for unattended operation up to 9999 minutes (≈7 days) with thermal cutoff protection at 90 °C. Duty cycle should not exceed 8 hours without bath replenishment in high-contaminant-load scenarios.
Is calibration required before first use?
No factory calibration is needed; however, users must verify temperature accuracy using a NIST-traceable thermometer before initiating GxP workflows. Annual verification is advised per ISO/IEC 17025 clause 6.5.
Does the SBL-22DT meet FDA requirements for medical device cleaning?
It fulfills the physical cleaning performance criteria outlined in FDA Guidance for Industry: Reprocessing Medical Devices in Health Care Settings (2022), provided users validate their specific process—including detergent selection, exposure time, and rinse protocol—per AAMI TIR30.
