Branson B2510E-MTH Ultrasonic Cleaner

Overview

The Branson B2510E-MTH Ultrasonic Cleaner is a benchtop, general-purpose cleaning system engineered for precision laboratory and light industrial applications. It operates on the principle of high-frequency acoustic cavitation: at 40 kHz, piezoelectric transducers generate ultrasonic pressure waves in the cleaning solution, inducing controlled microbubble formation and implosive collapse near submerged surfaces. This transient cavitation delivers localized mechanical energy sufficient to dislodge particulate contaminants, organic residues, oils, and biofilms from complex geometries—including blind holes, crevices, and microstructured surfaces—without mechanical abrasion or surface damage. Designed for reproducible, non-destructive cleaning of delicate instrumentation, optical components, analytical glassware, printed circuit boards (PCBs), and surgical tools, the B2510E-MTH integrates thermal control, programmable timing, and acoustic uniformity optimization into a compact, CE-compliant platform.

Key Features

• Corrosion-resistant polypropylene (PP) tank construction with chemical resistance to common aqueous and mild solvent-based cleaning solutions
• Langevin-type transducer assembly featuring metal-ceramic composite elements for long-term stability and consistent energy coupling
• Spherical wave propagation design ensures homogeneous cavitation distribution across the full tank volume (241 × 139 × 101 mm internal dimensions)
• Intelligent sweep-frequency modulation maintains continuous acoustic output and prevents standing-wave node formation
• Vertically oriented internal PCB layout with conformal coating for enhanced moisture and condensation resistance
• Ergonomic control panel mounted above the tank rim to minimize liquid ingress risk during operation
• Digital dual-display interface showing real-time bath temperature and user-set target temperature (range: 0–70 °C)
• Precise timer function with adjustable duration from 1 to 99 minutes in 1-minute increments
• Integrated sound-dampening lid with hinge-mounted flip mechanism—doubles as a drip tray and incorporates a manual drain valve for rapid fluid evacuation
• Optimized fill-level indicator line ensuring maximum ultrasonic energy transfer efficiency at standard operating volume (2.8 L)

Sample Compatibility & Compliance

The B2510E-MTH accommodates a wide range of sample types, including glass vials, stainless-steel fixtures, ceramic substrates, silicon wafers, and polymer-based medical devices. Its 40 kHz frequency provides an optimal balance between cleaning intensity and surface safety for most non-porous substrates. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61010-1 (safety requirements for electrical equipment used in laboratory environments). While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, it supports GLP-aligned cleaning validation protocols when integrated into documented SOPs. Users are advised to select compatible cleaning chemistries validated for material compatibility and residue removal efficacy under ASTM F3262 and ISO 15883-5 guidelines.

Software & Data Management

This model operates via embedded firmware without external software dependency. All operational parameters—including time, temperature, and power level—are stored in non-volatile memory and retained after power cycling. The digital interface logs last-used settings for immediate recall but does not support audit trail generation, remote monitoring, or data export. For laboratories requiring electronic record integrity under 21 CFR Part 11, integration with third-party environmental monitoring systems (e.g., via RS-232 or analog voltage output modules) is feasible through optional hardware adapters—subject to site-specific validation.

Applications

• Routine decontamination of HPLC vials, pipette tips, and electrophoresis combs prior to analytical use
• Preparation of electron microscopy specimens by removing hydrocarbon contamination from metal grids
• Cleaning of optical lenses and laser optics where solvent wiping risks micro-scratching
• Removal of flux residues from assembled PCBs in electronics QA/QC workflows
• Surface preparation of titanium and cobalt-chrome dental prostheses before passivation or coating
• Supporting ISO 14644-1 cleanroom component cleaning verification protocols
• Pre-analytical sample handling in clinical labs—including hematology slide racks and centrifuge buckets

FAQ

What is the recommended cleaning solution for this unit?
Aqueous alkaline or neutral pH detergents formulated for ultrasonic use are preferred; avoid halogenated solvents unless explicitly approved by Branson for PP tank compatibility.
Can the unit operate continuously beyond 99 minutes?
No—the maximum timer setting is 99 minutes; extended cycles require manual restart or integration with external programmable controllers.
Is the heating function independent of ultrasonic activation?
Yes; temperature control operates independently, allowing pre-heating of the bath prior to sonication initiation.
Does the B2510E-MTH include degassing functionality?
It lacks automated degas mode; however, the sweep-frequency algorithm and initial 5–10 minute low-power warm-up period effectively reduce dissolved gas content in fresh solutions.
How often should transducer performance be verified?
Branson recommends annual verification using calibrated aluminum foil erosion testing per ASTM E1758, especially in regulated environments where cleaning efficacy must be documented.
