Ningbo Scientz SB-800DT Digital Heated Ultrasonic Cleaner

Overview

The Ningbo Scientz SB-800DT is a benchtop digital heated ultrasonic cleaner engineered for precision cleaning, degassing, and sample preparation in regulated laboratory environments. It operates on the principle of acoustic cavitation: high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers are transmitted through an aqueous or compatible solvent medium, inducing transient microbubble formation and collapse. This implosive process generates localized pressures exceeding 1000 atm and temperatures up to 5000 K—sufficient to disrupt weak intermolecular bonds, dislodge particulate contaminants, emulsify organic residues, and accelerate mass transfer without mechanical abrasion. Unlike non-heated units, the SB-800DT integrates PID-controlled heating (ambient to 80 °C), which enhances solubility of waxy, lipidic, or polymer-based soils and improves cavitation efficiency in viscous media. Its 30-liter stainless-steel tank (304 grade) supports batch processing of large-volume glassware, multi-well plates, surgical instruments, and optical components—making it suitable for QC labs, pharmaceutical manufacturing support, academic core facilities, and medical device reprocessing workflows.

Key Features

• Digital PID temperature control with ±1 °C accuracy across 0–80 °C range, enabling reproducible thermal-assisted cleaning protocols
• Adjustable ultrasonic power output (0–100% in 10% increments), allowing optimization for delicate optics versus robust metal parts
• Programmable timer (1–99 minutes) with real-time countdown display and automatic shutdown
• Integrated sound-dampening lid with safety interlock—reduces ambient noise to <55 dB(A) and prevents solvent evaporation
• Stainless-steel tank with integrated drain valve and fill port for rapid solution exchange and residue-free maintenance
• Non-volatile memory retains last-used settings (time, temperature, power) after power interruption—ensuring protocol continuity in GLP/GMP-aligned operations
• Over-temperature and dry-run protection circuits prevent heater element damage and ensure operator safety

Sample Compatibility & Compliance

The SB-800DT accommodates a broad spectrum of sample formats: borosilicate glassware (vials, flasks, cuvettes), stainless-steel surgical tools, titanium dental implants, quartz optics, silicon wafers, and polymer-based microfluidic devices. Its cleaning efficacy has been validated against ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricating Oils) and ISO 15883-1 (Washer-disinfectors for heat-labile medical devices). While not certified as a medical device under FDA 510(k) or EU MDR, its design supports compliance with AAMI ST37 and ISO 17664 for pre-cleaning validation in sterile processing departments. The unit meets IEC 61010-1 safety requirements for laboratory electrical equipment and carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).

Software & Data Management

The SB-800DT operates via embedded firmware with no external software dependency. All operational parameters—including elapsed time, set temperature, applied power level, and cycle completion status—are logged to non-volatile memory. Though it lacks USB or Ethernet connectivity, its parameter retention function satisfies basic audit-trail requirements for laboratories operating under GLP or internal SOP frameworks. For full 21 CFR Part 11 compliance, users may integrate the unit into facility-wide monitoring systems via analog output modules (optional accessory) or manual logbook documentation aligned with Annex 11 principles.

Applications

• Routine decontamination of volumetric glassware, centrifuge tubes, and HPLC flow cells prior to analytical use
• Removal of biofilm, protein adhesion, and endotoxin residues from reusable surgical instruments and endoscopes (as part of validated multi-step reprocessing)
• Preparation of nanoparticle suspensions and liposome formulations via sonication-assisted dispersion and homogenization
• Mobile phase degassing for LC-MS and GC systems to reduce baseline noise and improve detector stability
• Cleaning of precision optical surfaces—including microscope objectives, interferometer mirrors, and photomask substrates—without surface scratching
• Extraction of intracellular metabolites from microbial pellets or plant tissues using solvent-assisted ultrasonication

FAQ

Is the SB-800DT suitable for cleaning aluminum or soft metals?

Yes—when operated at reduced power (≤40%) and below 50 °C in neutral pH aqueous solutions, it minimizes pitting and oxidation risk. Avoid chloride-containing solvents.
Can this unit be used for sterilization?

No. Ultrasonic cleaning removes bioburden but does not achieve sterility assurance levels (SAL 10⁻⁶). It serves as a critical pre-sterilization step only.
What is the recommended cleaning solution for optical lenses?

A mixture of deionized water and 0.5% non-ionic detergent (e.g., Liquinox®), followed by two DI water rinse cycles at 35 °C and 30% power.
Does the unit support continuous operation?

Yes—thermal management and transducer cooling allow uninterrupted cycling for up to 8 hours; however, periodic rest intervals (≥10 min every 2 h) are advised for long-term reliability.
How often should the transducers be inspected?

Visual inspection for delamination or corrosion is recommended quarterly; performance verification (cavitation intensity mapping per ASTM E1734) should occur semiannually in GxP environments.
