FLUKO FA40D Digital High-Shear Dispersing Emulsifier

Overview

The FLUKO FA40D Digital High-Shear Dispersing Emulsifier is an industrial-grade laboratory disperser engineered for reproducible, scalable processing of demanding colloidal and multiphase systems. Based on the principle of rotor-stator high-shear homogenization, the FA40D generates intense hydrodynamic cavitation, turbulent flow, and extensional deformation within the working head—enabling efficient particle size reduction, droplet breakup, and interfacial stabilization in emulsions and suspensions. Its core architecture integrates a high-efficiency brushless motor delivering 1800 W nominal output, capable of sustaining stable operation across its full speed range (2,500–23,500 rpm) under load. With a maximum tip speed of 40 m/s and torque-optimized gearless drive, the system achieves consistent energy input density even at elevated viscosities up to 8,000 cP—making it suitable for applications ranging from nanoemulsion development to high-solid-content pigment dispersion.

Key Features

• Digitally controlled variable-speed operation with real-time RPM feedback via integrated LED display—ensuring precise process parameter documentation and repeatability.
• Modular rotor-stator working head (standard 40M configuration) fabricated entirely from electropolished SS316L, offering superior corrosion resistance and compliance with ISO 8502-3 surface cleanliness standards for pharmaceutical and cosmetic R&D.
• PTFE-lined shaft seal assembly providing chemical inertness and low-friction rotation, minimizing heat generation and extending service life during prolonged batch operation.
• Robust vertical support stand with dual-axis adjustable clamping mechanism, accommodating vessels from 500 mL beakers to 15 L jacketed reactors without reconfiguration.
• IP20-rated motor housing with thermal overload protection and automatic shutdown logic—designed for continuous-duty laboratory environments operating within 5–40 °C ambient temperature and ≤80% relative humidity.
• Tool-free head exchange system enabling rapid adaptation to alternative geometries (e.g., 25M for low-volume screening or 60M for high-throughput dispersion), all sharing identical mounting interface and torque coupling.

Sample Compatibility & Compliance

The FA40D accommodates a broad spectrum of sample types including aqueous and non-aqueous emulsions, polymer solutions, ceramic slurries, battery electrode pastes, and biopolymer hydrogels. Its SS316L wetted path meets USP Class VI and ASTM F899 material certification requirements for contact with pharmaceutical intermediates. While not intrinsically compliant with FDA 21 CFR Part 11, the instrument supports audit-trail-ready operation when integrated with validated LIMS or ELN platforms—allowing timestamped RPM logging, operator ID tagging, and electronic signature capture for GLP/GMP-aligned workflows. All electrical components conform to IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards.

Software & Data Management

The FA40D operates as a standalone analog-controlled instrument with digital readout; no embedded firmware or proprietary software is required. However, its analog 0–10 V speed control interface enables seamless integration with external programmable logic controllers (PLCs) or data acquisition systems (e.g., LabVIEW, MATLAB, or Delta Tau PMAC). Users may log RPM, duration, and batch ID via external DAQ hardware, supporting traceability frameworks aligned with ISO/IEC 17025 clause 7.7 (result reporting) and ASTM E2500-13 (verification of equipment performance). Optional RS-485 communication modules (sold separately) permit remote speed setpoint adjustment and status polling in automated reactor networks.

Applications

• Formulation development of oil-in-water and water-in-oil emulsions (e.g., topical creams, functional beverages, agrochemical concentrates).
• Rapid dispersion of nanomaterials (graphene oxide, TiO₂, SiO₂) into polymeric matrices without agglomerate reformation.
• Cell lysis and subcellular fractionation in bioprocessing where mechanical shear must exceed enzymatic methods in throughput and consistency.
• Preparation of stable pigment dispersions for inkjet inks and automotive coatings requiring <200 nm D90 particle distribution.
• Homogenization of high-viscosity lithium-ion battery cathode slurries (NMC, LFP) prior to coating validation per ISO 18562-2 biocompatibility testing protocols.
• Scale-down modeling of production-scale inline homogenizers—leveraging constant tip speed and power-per-unit-volume correlations defined in ISO 13320 Annex B.

FAQ

What is the recommended maintenance interval for the FA40D’s rotor-stator assembly?

Routine visual inspection and cleaning after each use are mandatory. Full disassembly, dimensional verification of rotor runout (<0.02 mm), and PTFE seal replacement are advised every 500 operational hours or annually—whichever occurs first.
Can the FA40D be used under inert atmosphere or vacuum conditions?

No. The standard design lacks pressure-rated sealing and is rated only for ambient atmospheric operation. For glovebox or vacuum-compatible dispersion, FLUKO offers the FA40D-V variant with modified shaft feedthrough and Viton O-rings.
Is calibration of the digital RPM display traceable to national standards?

Yes. FLUKO provides optional NIST-traceable calibration certificates (ISO/IEC 17025 accredited) upon request, covering both display accuracy (±0.5% FS) and actual shaft speed deviation measured via laser tachometer.
Does the FA40D comply with CE marking requirements?

The unit meets CE directives 2014/30/EU (EMC) and 2014/35/EU (LVD) when supplied with EU-spec power cord and certified by TÜV Rheinland (certificate #RHE-2023-XXXXX).
What safety certifications apply to the electrical system?

The motor drive complies with UL 61010-1 Ed.3 and IEC 61010-1:2010 for laboratory electrical equipment, including dielectric strength testing at 1500 V AC for 60 seconds and creepage/clearance distances verified per pollution degree 2.
