Ningbo Scientz SB-120DT Digital Ultrasonic Cleaner with Heating

Overview

The Ningbo Scientz SB-120DT is a digitally controlled, heated ultrasonic cleaner engineered for precision cleaning and auxiliary sample preparation tasks in research laboratories, quality control environments, and clinical support facilities. It operates on the principle of acoustic cavitation: high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers are transmitted through an aqueous or solvent-based cleaning medium, inducing the formation, growth, and implosive collapse of microscopic vacuum bubbles. This transient cavitation event produces localized shockwaves and microstreaming effects—mechanical forces sufficient to dislodge particulate contaminants, organic residues, and adsorbed films from complex geometries including blind holes, narrow lumens, porous surfaces, and microstructured substrates. Unlike manual scrubbing or immersion soaking, ultrasonic cleaning delivers uniform energy distribution without mechanical abrasion, preserving surface integrity of delicate items such as optical lenses, quartz cuvettes, microfluidic chips, and surgical instruments.

Key Features

• Digital timer with 1–99 minute programmable range and real-time countdown display
• Integrated heating system with precise temperature control from ambient up to 80 °C, enabling temperature-assisted dissolution of waxes, greases, and biofilms
• Large backlit LCD screen showing both set parameters and real-time bath temperature
• Automatic power-off protection and parameter memory function—retains last-used time and temperature settings after power interruption
• Sound-dampening lid reduces airborne noise and minimizes solvent evaporation during extended operation
• Stainless steel tank (3 L capacity) constructed from corrosion-resistant 304-grade stainless steel, compatible with common aqueous detergents, ethanol, isopropanol, and mild alkaline solutions
• Transducer assembly utilizes imported piezoceramic elements for stable output and long-term reliability under continuous duty cycles

Sample Compatibility & Compliance

The SB-120DT is validated for use with a broad spectrum of laboratory and industrial samples, including but not limited to: borosilicate glassware (vials, pipettes, Petri dishes), polypropylene centrifuge tubes, stainless steel forceps and scalpel handles, titanium dental implants, sapphire watch components, and fused silica optics. Its cleaning efficacy aligns with standard operating procedures referenced in ISO 15883-1 (washer-disinfectors), ASTM D4299 (ultrasonic cleaning verification), and USP (cleaning validation guidance). While the unit itself does not carry CE or UL certification out-of-box, its design conforms to IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for laboratory equipment). Users performing GLP/GMP-regulated cleaning must validate cycle parameters—including temperature stability, cavitation uniformity, and residue removal efficiency—using standardized test soils (e.g., bovine serum albumin, carbon black, or silicone oil) per internal SOPs.

Software & Data Management

The SB-120DT is a standalone hardware platform with no embedded firmware-based data logging or network connectivity. All operational parameters are configured via front-panel push-button interface; no external software, drivers, or cloud integration is required. However, the device supports audit-ready documentation through manual logbook entries or integration into facility-wide electronic lab notebook (ELN) systems. For regulated environments requiring traceability, users may pair the unit with external calibrated thermometers and stopwatch validation tools to generate raw data packages compliant with FDA 21 CFR Part 11 when combined with appropriate procedural controls (e.g., operator ID entry, cycle signature, timestamped printouts).

Applications

• Routine decontamination of reusable labware prior to sterilization or reuse
• Removal of residual solvents, coupling agents, or photoresist residues from semiconductor wafers and MEMS devices
• Pre-analytical sample preparation: cell lysis, nanoparticle dispersion, homogenization of tissue suspensions
• Mobile phase degassing for HPLC and UHPLC systems to reduce baseline noise and prevent pump cavitation
• Cleaning of endoscopic channels, orthopedic drill bits, and orthodontic appliances in clinical reprocessing workflows
• Restoration of optical clarity in microscope objectives, interferometer mirrors, and laser cavity components

FAQ

Is the ultrasonic power output adjustable?
No—the SB-120DT delivers a fixed 120 W nominal acoustic power at 40 kHz. Power modulation is not supported.
Can this unit be used with flammable solvents?
Only under strictly controlled conditions and with additional explosion-proof ventilation. The heater and electronics are not intrinsically safe; aqueous or high-flashpoint solvents (e.g., >60 °C flash point) are recommended.
Does the tank include a drain valve?
No—drainage requires manual decanting or siphoning. No inlet or outlet ports are integrated.
What is the typical cavitation intensity distribution across the tank?
Maximum cavitation occurs near transducer mounting zones (typically bottom-center); optimal loading practices recommend partial submersion and rotation of parts during extended cycles to ensure uniform exposure.
How often should the cleaning solution be replaced?
Solution replacement frequency depends on soil load and chemistry—typically every 4–8 hours of cumulative operation or upon visible turbidity, odor, or reduced cleaning performance.
