Branson B3510E-MT Ultrasonic Cleaner

Overview

The Branson B3510E-MT Ultrasonic Cleaner is an engineered solution for precision cleaning of small-to-medium components across laboratory, medical device reprocessing, industrial maintenance, dental instrumentation, jewelry fabrication, and academic research environments. It operates on the principle of ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in a liquid medium; upon collapse, these bubbles release localized energy sufficient to dislodge particulate contaminants, organic residues, light oils, oxides, and biofilms from surfaces—including complex geometries, blind holes, crevices, and internal channels inaccessible to manual scrubbing or spray cleaning. Designed as a benchtop, plug-and-play system, it integrates a stainless steel tank, solid-state ultrasonic transducer array, digital control interface, and thermostatically regulated heating—all housed within a durable, non-conductive polymer enclosure compliant with IEC 61010-1 safety standards for laboratory equipment.

Key Features

• Stainless steel tank (304 grade) with seamless construction—eliminates weld seams and porous surfaces that harbor residue or promote corrosion between cycles.
• Digital microprocessor-based controls enabling independent adjustment of ultrasonic power (0–100% in 10% increments), heating temperature (0–70 °C in 1 °C steps), and cycle duration (0–60 minutes in 1-minute increments).
• Integrated acoustic lid reduces ambient noise by >15 dB(A) and minimizes solvent evaporation during heated operation—critical for reproducible cleaning performance and operator safety.
• Thermostatic heating system maintains setpoint stability within ±2 °C across the full 0–70 °C range, supporting temperature-dependent cleaning chemistries per ASTM F3127 and ISO 15883-5 protocols.
• Solid-state ultrasonic generator with no moving parts ensures long-term reliability, low maintenance, and consistent energy delivery—validated for >10,000 hours MTBF under continuous lab use conditions.
• Manual fill-and-drain configuration allows compatibility with a broad spectrum of aqueous and non-flammable solvent-based cleaning solutions—including alkaline, neutral, enzymatic, and chelating formulations.

Sample Compatibility & Compliance

The B3510E-MT accommodates substrates ranging from delicate optical lenses and semiconductor wafers to surgical instruments, printed circuit boards, and precious metal components. Its 5.7 L tank volume and 292 × 152 × 152 mm internal dimensions support immersion of items up to 270 mm in length without compromising ultrasonic field uniformity. The unit complies with UL 61010-1 and CSA C22.2 No. 61010-1 for electrical safety, and its thermal and timing controls meet functional safety requirements outlined in IEC 62304 for Class B medical device accessories. When used with validated cleaning agents and documented SOPs, it supports GLP/GMP-aligned workflows—including traceable parameter logging (via optional RS-232 interface) required under FDA 21 CFR Part 11 for regulated quality control laboratories.

Software & Data Management

While the B3510E-MT operates via standalone front-panel controls, its RS-232 serial port enables integration with external data acquisition systems or laboratory information management systems (LIMS). Parameter settings—including time, temperature, and power level—are retained after power cycling. Optional firmware upgrades (available through Branson Technical Support) may extend audit-trail capabilities, including timestamped event logging for start/stop commands, temperature deviations, and fault codes—supporting compliance with ISO/IEC 17025 clause 7.7 on equipment calibration and usage records.

Applications

• Pre-analytical sample preparation: removal of residual buffers, salts, or protein adhesion from HPLC vials, pipette tips, and microcentrifuge tubes.
• Medical device reprocessing: cleaning of reusable laparoscopic instruments, endoscope components, and orthopedic implants prior to sterilization per AAMI ST91.
• Electronics manufacturing: degreasing of PCB assemblies and removal of flux residues before conformal coating or AOI inspection.
• Jewelry and watchmaking: non-abrasive removal of polishing compounds, wax residues, and tarnish from intricate settings and gemstone mounts.
• Materials science labs: surface decontamination of catalyst samples, powder metallurgy compacts, and MEMS devices prior to SEM/EDS analysis.

FAQ

What cleaning solutions are compatible with the B3510E-MT?
Aqueous alkaline, neutral pH, enzymatic, and low-volatility solvent-based cleaners are suitable—provided they are non-flammable and compatible with stainless steel and polymer housing materials. Avoid strong acids, halogenated solvents, or undiluted oxidizers.
Can this unit be used for sterilization?
No. Ultrasonic cleaning is a pre-sterilization step only. It removes bioburden but does not achieve sterility assurance levels (SAL) required by ISO 11135 or ISO 11137. Autoclaving, ethylene oxide, or hydrogen peroxide plasma must follow cleaning.
Is the stainless steel tank passivated?
Yes. All Branson stainless steel tanks undergo electropolishing and nitric acid passivation per ASTM A967 to maximize corrosion resistance and minimize metallic ion leaching into cleaning solutions.
How often should the tank be descaled?
Frequency depends on water hardness and usage intensity. In hard-water regions, descaling every 2–4 weeks with a citric acid-based solution is recommended to maintain heating efficiency and ultrasonic transmission integrity.
Does the unit include a warranty?
Branson provides a standard 2-year limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use conditions. Extended service plans are available through authorized distributors.
