FLUKO EU50 PRO Multifunctional Electric Laboratory Stirrer

Overview

The FLUKO EU50 PRO Multifunctional Electric Laboratory Stirrer is an engineered solution for precise, reproducible mixing and dispersion across a broad spectrum of viscosities—from low-viscosity aqueous solutions to highly structured non-Newtonian systems up to 40,000 cP. Designed for R&D laboratories, quality control units, and pilot-scale formulation development, it employs a high-efficiency brushless DC motor coupled with real-time torque sensing and closed-loop speed regulation to maintain consistent shear input under variable load conditions. Its modular architecture supports integration into automated workflows via standardized communication protocols, while its robust mechanical design—including adjustable-height stainless-steel support column, IP30-rated enclosure, and thermally protected motor—ensures long-term operational stability in regulated environments compliant with GLP and ISO/IEC 17025 requirements.

Key Features

• Brushless DC motor delivering continuous torque output up to 50 N·cm with thermal and overload protection
• Real-time dynamic torque monitoring and display, enabling correlation between rotational energy input and rheological response
• TFT LCD interface with intuitive touch buttons and rotary encoder for one-handed operation and parameter recall
• Precise speed control across 30–2000 rpm range with ±1 rpm resolution and digital feedback stabilization
• Integrated temperature measurement capability via optional PT1000 probe (−50 to 400 °C), supporting exothermic/endothermic process monitoring
• Programmable timer (0–99 h 59 min 59 s) with automatic shutdown and memory retention for repeatable batch execution
• Automatic tilt detection: immediate motor cutoff upon ≥30° inclination, enhancing operator safety and equipment integrity
• Reversible rotation mode with programmable dwell intervals, facilitating deagglomeration and suspension homogenization
• USB Type-C and DB-9 serial interfaces for bidirectional data exchange with external controllers or LIMS platforms
• Modular mounting system compatible with standard lab stands and optional gas-spring height-adjustable workstations

Sample Compatibility & Compliance

The EU50 PRO accommodates vessels from 50 mL beakers to 30 L jacketed reactors, supporting common laboratory geometries including cylindrical, conical, and flat-bottom containers. Its four-blade helical impeller—fabricated from electropolished SS316L—resists corrosion and minimizes particle adhesion during high-shear dispersion of pigments, nanoparticles, or polymer melts. The device complies with electromagnetic compatibility standards IEC/EN 61000-6-3 (emissions) and -6-4 (immunity), as well as electrical safety standard EN 61326-1. Optional software EU Control enables audit-trail generation and user-access logging, aligning with FDA 21 CFR Part 11 requirements for electronic records in regulated pharmaceutical and biotech applications.

Software & Data Management

When paired with the optional EU Control software suite (Windows-based), the EU50 PRO transforms into a data-enabled endpoint within digital lab infrastructures. The software provides remote configuration, real-time graphing of torque vs. time and temperature vs. speed profiles, and CSV export of timestamped datasets—including RPM, torque %, measured temperature, and elapsed runtime. All parameter changes are logged with user ID, timestamp, and value delta, fulfilling traceability mandates under ISO 17025 Clause 7.7 and GMP Annex 11. Data synchronization supports both local storage and networked database ingestion via ODBC-compliant drivers.

Applications

• Formulation development of emulsions, suspensions, and colloidal dispersions in pharmaceutical, cosmetic, and food R&D
• Preparation of electrode slurries and battery electrolyte blends requiring controlled shear history
• In-process viscosity tracking during polymerization or crosslinking reactions
• Homogenization of cell culture media containing heat-sensitive additives
• Dispersion of nanomaterials (e.g., graphene oxide, metal oxides) where torque transients indicate agglomerate breakdown
• QC testing of industrial lubricants and coatings per ASTM D2196 or ISO 2557
• Teaching labs demonstrating Newtonian/non-Newtonian fluid behavior through controlled ramp-and-hold protocols

FAQ

Does the EU50 PRO support regulatory-compliant data archiving?
Yes—when used with EU Control software, it generates ALCOA+ compliant audit trails, including electronic signatures, immutable logs, and version-controlled method files.
Can the stirrer operate continuously for extended durations?
It is rated for continuous duty at ambient temperatures ≤40 °C and relative humidity ≤80 % RH, with built-in thermal cut-off at 75 °C motor winding temperature.
Is third-party calibration supported?
Torque and speed sensors are factory-calibrated; users may perform periodic verification using NIST-traceable reference standards and documented SOPs.
What impeller types are compatible beyond the standard SS316L helix?
The 0.5–10 mm chuck accepts custom impellers—including anchor, paddle, turbine, and disperser types—provided they meet dynamic balance specifications for ≤2000 rpm operation.
How is firmware updated?
Firmware upgrades are delivered via USB Type-C connection using EU Control software, with checksum validation and rollback capability.
