Branson M5800-C Benchtop Ultrasonic Cleaner

Overview

The Branson M5800-C is a precision-engineered benchtop ultrasonic cleaner designed for consistent, repeatable cleaning performance in analytical, quality control, and research laboratory environments. It operates on the principle of high-frequency (40 kHz) ultrasonic cavitation—where acoustic energy induces rapid formation and collapse of microscopic vapor bubbles in the cleaning solution—generating localized micro-jets and shockwaves that dislodge particulate contaminants from surfaces without mechanical abrasion. Engineered for reliability and regulatory compliance, the M5800-C integrates Branson’s proprietary power-tracking circuitry and sweep-frequency technology to maintain stable acoustic output across varying load conditions, liquid levels, and transducer aging—ensuring reproducible cleaning efficacy critical for validated processes under GLP, ISO 17025, and FDA-regulated workflows.

Key Features

• Intelligent power-tracking electronics automatically adjust drive amplitude to compensate for changes in tank loading, solution composition, or temperature—preserving consistent cavitation intensity and cleaning uniformity.
• Sweep-frequency operation (±1 kHz around 40 kHz center frequency) eliminates standing wave nodes and ensures homogeneous energy distribution throughout the tank volume, optimizing particle removal across complex geometries and multi-part loads.
• Langevin-type piezoelectric transducers—constructed with ceramic elements bonded to titanium alloy horns—deliver high electromechanical coupling efficiency and extended operational lifetime (>10,000 hours MTBF).
• Vertical PCB mounting and elevated control interface minimize moisture ingress; all electronics are conformally coated and isolated from the ultrasonic tank assembly to enhance long-term stability in humid lab environments.
• Chemically resistant polypropylene (PP) outer housing combined with a seamless 304 stainless steel tank provides robust protection against acidic, alkaline, and organic solvents commonly used in degreasing, descaling, and residue removal protocols.
• Dual-function hinged lid serves as both acoustic dampener and integrated drip tray; built-in drain valve enables rapid, spill-free solution exchange—critical for multi-step cleaning sequences or solvent recovery workflows.
• Precisely calibrated fill line ensures optimal liquid depth for maximum acoustic coupling and energy transfer efficiency, reducing power waste and thermal drift during extended cycles.

Sample Compatibility & Compliance

The M5800-C accommodates a broad range of sample types—including glassware, metal components, printed circuit boards, surgical instruments, optical lenses, and semiconductor wafers—without risk of surface pitting or micro-scratching when operated within recommended parameters. Its 9.5 L capacity supports batch processing of up to 20 standard 50-mL centrifuge tubes or four 100-mm Petri dishes simultaneously. All units comply with electromagnetic compatibility (EMC) and safety standards per IEC/EN 61000-6-3, IEC/EN 61000-6-4, UL 61010-1, CSA C22.2 No. 61010-1, and FCC Part 15 Subpart B. Full TÜV Rheinland certification confirms conformity with stringent electrical safety, insulation integrity, and fault-condition resilience requirements—making it suitable for installation in ISO Class 5–8 cleanrooms and regulated manufacturing facilities operating under 21 CFR Part 11-compliant data governance frameworks.

Software & Data Management

While the M5800-C utilizes an analog electromechanical timer (0–60 min or continuous mode), its hardware architecture supports optional digital upgrade modules—including RS-232 or USB interfaces—for integration into centralized lab equipment monitoring systems. When paired with Branson’s optional LabLink™ software suite (sold separately), users gain audit-trail-enabled cycle logging, time-stamped event records, operator ID authentication, and exportable CSV reports compliant with ALCOA+ data integrity principles. Firmware updates preserve backward compatibility and support future validation documentation packages required for IQ/OQ/PQ protocols in pharmaceutical and medical device QA/QC laboratories.

Applications

This system is routinely deployed in applications requiring non-destructive, residue-free surface preparation prior to spectroscopic analysis (e.g., FTIR, XRF, SEM-EDS), chromatographic injection (HPLC, GC), mass spectrometry sample introduction, or coating adhesion testing. It is widely adopted for pre-sterilization cleaning of reusable surgical tools in hospital central supply departments, removal of flux residues from SMT assemblies in electronics manufacturing, and decontamination of quartz cuvettes and NMR tubes in academic core facilities. Its stable 40 kHz output and sweep functionality make it particularly effective for removing sub-micron particles, biofilms, and dried protein matrices from stainless steel, silicon, and borosilicate substrates.

FAQ

Is the M5800-C suitable for use with flammable solvents?
No—this unit is designed exclusively for aqueous or water-miscible solutions. Flammable solvents require intrinsically safe, explosion-proof ultrasonic systems with certified vapor containment and grounding provisions.
Can the timer be bypassed for continuous operation?
Yes—the mechanical timer includes a dedicated “ON” position enabling uninterrupted ultrasonic output until manually powered down.
What maintenance is required to ensure long-term performance?
Routine inspection of the drain valve seal, periodic descaling of the tank using diluted acetic acid, and verification of transducer bond integrity every 12 months (per manufacturer’s service bulletin SB-M5800-03) are recommended.
Does the unit include a degas function?
No—degassing must be performed externally or via manual cycling (30 sec ON / 30 sec OFF) before initiating critical cleaning cycles to minimize bubble interference with cavitation efficiency.
Is calibration documentation available for GMP environments?
Yes—NIST-traceable calibration certificates for frequency stability and power output verification are available upon request and included in the optional Validation Support Package (VSP-M5800).
