Ningbo Scientz SBL-10DT Benchtop Ultrasonic Cleaner

Overview

The Ningbo Scientz SBL-10DT is a benchtop ultrasonic cleaner engineered for precision cleaning in academic, pharmaceutical, clinical, and industrial laboratory environments. It operates on the principle of acoustic cavitation: high-frequency mechanical vibrations (40 kHz) generated by piezoelectric transducers are transmitted through the cleaning medium—typically aqueous or solvent-based solutions—inducing the formation, growth, and violent collapse of microscopic vacuum bubbles. This implosive collapse releases localized energy in the form of micro-jets and shockwaves, enabling effective removal of particulate contaminants, organic residues (e.g., oils, greases), biofilms, and adsorbed layers from complex geometries—including blind holes, narrow lumens, microchannels, and porous surfaces—without mechanical abrasion or surface damage.

Key Features

• Stainless steel tank (304 grade) with 10-liter capacity, designed for chemical resistance and long-term structural integrity under continuous ultrasonic loading.
• Digital touch-screen interface providing real-time display of elapsed time and internal bath temperature (where heating option is installed).
• Programmable timer with adjustable range from 1 to 9999 minutes, supporting both single-cycle and multi-step cleaning protocols.
• Integrated sound-dampening lid to reduce ambient noise levels and minimize solvent evaporation during operation.
• Robust transducer array mounted directly to the tank bottom, ensuring uniform energy distribution across the entire cleaning volume.
• Power-fail memory function retains user-defined settings—including timer value and temperature setpoint—after unexpected power interruption.

Sample Compatibility & Compliance

The SBL-10DT accommodates a broad range of sample types and materials, including borosilicate glassware (vials, flasks, pipettes), polymer-based consumables (centrifuge tubes, microplates), metallic components (surgical instruments, precision bearings, fuel injectors), optical elements (lens assemblies, quartz cuvettes), and delicate artifacts (jewelry, watch mechanisms). Its non-contact cleaning mechanism ensures compatibility with fragile, heat-sensitive, or electrostatically charged substrates. While the base model does not include temperature regulation, optional heating modules (up to 80 °C) support enhanced solubilization of waxy or viscous contaminants. The unit conforms to general electrical safety standards applicable to Class I laboratory equipment (IEC 61010-1) and supports GLP-compliant documentation when integrated into validated workflows. Note: For regulated applications requiring traceability (e.g., ISO 13485, FDA 21 CFR Part 11), external data logging and audit trail systems must be implemented separately.

Software & Data Management

The SBL-10DT operates via embedded firmware without external PC connectivity or proprietary software. All operational parameters—including timer value and (if equipped) heating setpoint—are stored locally in non-volatile memory. No USB, Ethernet, or RS-232 interfaces are provided; therefore, automated data export, remote monitoring, or electronic record retention is not natively supported. Users requiring electronic documentation may integrate the unit into facility-wide environmental monitoring systems using analog voltage outputs (available on select upgraded configurations) or employ third-party time-lapse cameras and calibrated thermistors for independent verification of cycle execution and thermal stability.

Applications

• Cleaning of analytical labware prior to HPLC, GC, or ICP-MS analysis to prevent carryover contamination and ensure measurement reproducibility.
• Preparation of cell culture vessels and surgical tools in biosafety level 2 (BSL-2) facilities, often as a pre-sterilization step before autoclaving or ethylene oxide treatment.
• De-gassing of solvents and reagent solutions to eliminate dissolved air that could interfere with spectroscopic measurements or vacuum-based processes.
• Assisted extraction of intracellular components (e.g., proteins, nucleic acids) from tissue homogenates or microbial pellets under controlled low-energy conditions.
• Maintenance cleaning of optical components where traditional wiping risks micro-scratching or residue deposition.
• Industrial quality assurance tasks such as post-machining deburring of microelectromechanical systems (MEMS) components or flux residue removal from printed circuit board assemblies.

FAQ

Is the SBL-10DT suitable for cleaning delicate optics or semiconductor wafers?

Yes—when operated with low-concentration, low-surface-tension surfactant solutions and at reduced duty cycles, it effectively removes submicron particles without surface etching or coating delamination.
Does the unit meet ISO 17025 calibration requirements?

No—calibration of ultrasonic intensity and cavitation distribution requires specialized hydrophone-based mapping and is performed externally per ISO/IEC 17025-accredited laboratories. The SBL-10DT itself is not supplied with calibration certificates.
Can the cleaning tank be filled with organic solvents?

Only if the solvent is compatible with 304 stainless steel and has a flash point above 60 °C. Acetone, chloroform, and ethanol require explosion-proof variants not offered in this model.
What maintenance is required for long-term reliability?

Transducer coupling integrity should be verified annually; tank interior must be rinsed after each use with deionized water to prevent mineral buildup; ultrasonic generator cooling fans require biannual dust removal.
Is there an option for integrated temperature control?

The standard SBL-10DT lacks heating capability. However, Scientz offers parallel models (e.g., SBL-10DTH) with PID-controlled heating up to 80 °C—these are distinct SKUs and require separate ordering.
