Brookfield B5510E-DTH Ultrasonic Cleaner

Overview

The Brookfield B5510E-DTH Ultrasonic Cleaner is a precision-engineered laboratory cleaning system designed for reproducible, non-destructive removal of particulate, organic, and ionic contaminants from delicate instrumentation, glassware, surgical tools, and analytical components. It operates on the principle of high-frequency acoustic cavitation—where controlled 40 kHz ultrasonic energy induces rapid formation and collapse of microscopic vapor bubbles in aqueous or mild solvent-based cleaning media. This transient cavitation generates localized micro-jets and shear forces capable of dislodging sub-micron residues without mechanical abrasion. Engineered for routine QC/QA laboratories, R&D facilities, and regulated environments—including those adhering to ASTM D2603, ISO 13485, and USP guidelines—the B5510E-DTH delivers consistent energy distribution across its 9.46 L polypropylene tank via Brookfield’s proprietary spherical wave propagation design. Its robust architecture integrates thermal stability, electrical isolation, and user-centric ergonomics to support daily operation under GLP/GMP-aligned workflows.

Key Features

• Polypropylene (PP) tank and housing engineered for chemical resistance against dilute acids, bases, and common lab solvents—ensuring long-term structural integrity in aggressive cleaning protocols.
• Langevin-type metal-ceramic transducers mounted vertically using aerospace-grade adhesive bonding—minimizing delamination risk and sustaining resonant efficiency over extended duty cycles.
• Dual-mode digital control interface with real-time LED display: simultaneously monitors actual bath temperature and user-defined heating setpoint with ±0.5 °C stability across the 0–70 °C range.
• Intelligent sweep-frequency modulation maintains uniform acoustic energy distribution throughout the entire tank volume—eliminating standing-wave dead zones and enhancing cleaning homogeneity.
• Vertically oriented internal PCB layout with conformal coating provides enhanced moisture and condensation resistance—critical for humid lab environments and repeated thermal cycling.
• Ergonomic top-mounted control panel positioned above the tank rim prevents liquid ingress during operation and simplifies calibration verification and parameter entry.
• Hinged acoustic lid functions both as noise-dampening enclosure (reducing ambient sound pressure by up to 15 dB(A)) and removable drip tray—with integrated quick-release drain valve enabling full tank evacuation in under 30 seconds.
• Precision water-level indicator etched into the tank interior ensures optimal coupling between transducers and cleaning solution—maximizing energy transfer efficiency at the standard operating fill height.
• Reinforced plastic-overmolded power switch rated for >100,000 actuation cycles—designed to withstand frequent use while maintaining IP54-rated ingress protection.

Sample Compatibility & Compliance

The B5510E-DTH accommodates a broad spectrum of sample geometries and material classes, including stainless steel instruments, borosilicate glassware (vials, cuvettes, pipette tips), ceramic substrates, silicon wafers, and polymer-based microfluidic devices. Its 292 × 241 × 152 mm chamber supports standard rack configurations (e.g., 100-mm test tube racks, 96-well plate holders) and permits immersion of multi-component assemblies up to 140 mm in height. The unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61010-1 (safety requirements for laboratory equipment). Optional accessories—including ultrasonic baskets, beaker holders, and degassing trays—are certified compatible and documented per ISO 17025 traceability standards. For regulated applications, the device supports audit-ready documentation when paired with Brookfield’s optional data logger module (sold separately), enabling timestamped temperature/timer logs compliant with FDA 21 CFR Part 11 requirements.

Software & Data Management

While the B5510E-DTH operates as a standalone benchtop instrument with no embedded firmware or network connectivity, its digital control system records all operational parameters—including elapsed time, final temperature, and cycle completion status—in volatile memory for immediate visual verification. For laboratories requiring electronic record retention, Brookfield recommends integration with validated third-party environmental monitoring systems via analog voltage output (0–5 V DC proportional to bath temperature) or dry-contact relay signals (for timer end-of-cycle notification). All configuration changes are logged locally on the front-panel display; no password protection or user-level access controls are implemented, consistent with Class I non-networked instrumentation per GAMP5 Annex 11 guidance.

Applications

This ultrasonic cleaner serves critical roles in pharmaceutical manufacturing (pre-sterilization cleaning of filling needles and stopper contact surfaces), clinical diagnostics (decontamination of hematology analyzers and PCR prep stations), materials science (removal of sputtering residues from TEM grids), and academic research (cleaning of quartz crystal microbalance sensors and AFM probes). It is routinely deployed prior to surface characterization (XPS, SEM, contact angle measurement), coating adhesion testing, and high-purity solvent recovery processes. Its stable 40 kHz frequency and optimized power density (19.5 W/L) make it especially suitable for removing biofilm matrices, solder flux residues, and colloidal silica without inducing micro-scratches or thermal degradation.

FAQ

Is the B5510E-DTH suitable for cleaning delicate optical components?

Yes—when operated with low-concentration, non-ionic surfactants and deionized water at temperatures ≤45 °C, the unit reliably cleans lenses, mirrors, and fiber-optic connectors without surface etching or coating delamination.
Can the heater and ultrasonics operate independently?

Yes—the control system allows simultaneous, sequential, or isolated activation of heating and ultrasonic modes, enabling cold sonication for thermally sensitive samples or hot rinse cycles without cavitation.
What maintenance is required for long-term reliability?

Routine tasks include quarterly inspection of transducer bond integrity, biannual descaling of the heater element using 5% citric acid solution, and annual verification of timer accuracy against a calibrated stopwatch.
Does the unit include validation documentation for IQ/OQ protocols?

Factory-installed units ship with a Certificate of Conformance and basic performance verification report. Full IQ/OQ protocol templates and on-site qualification support are available through Brookfield’s Professional Services division.
Is the tank drain valve compatible with standard laboratory floor drain fittings?

The 1/4″ NPT female outlet accepts standard laboratory-grade flexible PVC tubing (ID 6 mm); adapters for 3/8″ or 1/2″ municipal drains are available as optional accessories.
