FLUKO FA90-241-E Pilot-Scale High-Shear Dispersing & Homogenizing System

Overview

The FLUKO FA90-241-E is a pilot-scale high-shear rotor-stator homogenizing system engineered for process development, scale-up validation, and small-batch manufacturing in pharmaceutical, chemical, cosmetic, and food R&D facilities. It operates on the principle of controlled hydrodynamic cavitation and intense mechanical shear generated between a rapidly rotating inner rotor and a precisely engineered stationary stator—commonly referred to as the “90F” working head. This geometry ensures uniform energy input across the entire processing volume, enabling reproducible particle size reduction, droplet breakup, dispersion stabilization, and interfacial area maximization in liquid–liquid and solid–liquid systems. Unlike laboratory-scale homogenizers, the FA90-241-E bridges the gap between benchtop feasibility studies and full production line integration, supporting consistent batch-to-batch performance under GMP-aligned operating conditions.

Key Features

• Robust 1500 W brushless motor with frequency-inverter-based speed control (600–3600 rpm), delivering precise torque response and stable rotational output across viscosity ranges up to 8000 cP.
• Digital RPM display with real-time feedback, ensuring traceable operational parameters for SOP compliance and audit readiness.
• Electrically actuated vertical lift column (400 mm stroke) with adjustable positioning lock, facilitating safe and repeatable immersion depth control during batch processing.
• Modular rotor-stator architecture: Interchangeable 90F standard head (SS316L) optimized for general-purpose emulsification and dispersion; compatible with optional high-efficiency geometries (e.g., fine-gap, multi-stage, or high-flow variants) for specialized applications.
• Full wetted-path construction using electropolished SS316L and chemically inert PTFE shaft sleeves—designed to meet USP Class VI and FDA-compliant material requirements for non-reactive contact surfaces.
• IP54-rated motor housing with integrated thermal and current overload protection, suitable for continuous operation in ambient environments between 5–40 °C and ≤80% RH.

Sample Compatibility & Compliance

The FA90-241-E accommodates batch volumes from 10 to 50 L of aqueous, solvent-based, or semi-viscous formulations—including oil-in-water and water-in-oil emulsions, pigment dispersions, polymer suspensions, nanoparticle slurries, and protein-containing biopharmaceutical intermediates. Its sealed, low-turbulence design minimizes foaming and volatiles loss during extended processing cycles. The system conforms to ISO 13485 design principles for medical device-associated equipment and supports GLP/GMP documentation workflows through configurable operator access levels and electronic log generation (when paired with optional data acquisition modules). While not intrinsically certified for hazardous area use, it complies with IEC 61000-6-2/6-4 EMC standards and meets CE marking requirements for machinery safety (2006/42/EC).

Software & Data Management

The FA90-241-E operates as a standalone instrument with embedded firmware governing motor dynamics, thermal monitoring, and lift actuation sequencing. For enhanced process traceability, FLUKO offers optional USB- or RS485-enabled interface modules that export time-stamped RPM, torque, and runtime data to external SCADA or LIMS platforms. When deployed in regulated environments, these interfaces support 21 CFR Part 11–compliant audit trails—including user authentication, electronic signatures, and immutable parameter logging—provided the host software infrastructure implements appropriate security controls. No proprietary cloud service or vendor-hosted platform is required; all data remains under end-user control.

Applications

• Pharmaceutical: Preparation of nanoemulsions for oral or topical delivery, active pharmaceutical ingredient (API) suspension stabilization, and pre-formulation screening of excipient compatibility.
• Chemical: Carbon black dispersion in rubber compounds, catalyst slurry homogenization, and silicone emulsion synthesis.
• Food & Beverage: Mayonnaise and dressing base development, plant-protein isolate dispersion, and functional ingredient incorporation into viscous matrices.
• Materials Science: Graphene oxide dispersion in polymer precursors, ceramic nanoparticle suspension for coating formulations, and battery electrode slurry conditioning.
• Academic Research: Shear-rate-dependent rheological profiling of complex fluids, mechanistic studies of emulsion inversion, and structure–property correlation in soft matter systems.

FAQ

What is the maximum recommended viscosity for continuous operation?
The FA90-241-E is rated for sustained processing of Newtonian and pseudo-plastic fluids up to 8000 cP at mid-range speeds (1800–2800 rpm); operation above this limit requires reduced speed and intermittent duty cycling to prevent thermal overload.
Can the 90F working head be sterilized in place (SIP)?
No—this is a batch-processing system intended for clean-in-place (CIP) protocols only; steam sterilization is not supported due to PTFE component limitations and lack of pressure-rated sealing.
Is the electric lift mechanism programmable?
Standard configuration provides manual initiation of ascent/descent with position locking; programmable lift sequences require integration with an external PLC or FLUKO’s optional HMI controller module.
Does FLUKO provide IQ/OQ documentation packages?
Yes—validated installation qualification (IQ) and operational qualification (OQ) templates are available upon request, aligned with ASTM E2500 and ISO/IEC 17025 guidance for analytical instrument qualification.
What maintenance intervals are recommended for routine operation?
Biannual inspection of rotor-stator clearance, bearing preload, and electrical connections is advised; annual recalibration of speed feedback circuitry is recommended for GLP-critical applications.
