IKA Eurostar 100 Digital & Control Stirrers

Overview

The IKA Eurostar 100 series comprises two high-performance laboratory stirrers—Eurostar 100 Digital and Eurostar 100 Control—engineered for precision mixing, dispersion, and homogenization of low- to high-viscosity liquids in research, quality control, and pilot-scale development environments. Both models employ brushless DC motor technology, delivering consistent torque output, extended service life, and minimal electromagnetic interference. The core operating principle relies on closed-loop speed regulation via microprocessor-based feedback control: real-time comparison between setpoint and actual shaft speed enables continuous correction, ensuring rotational stability even during dynamic viscosity shifts (e.g., polymer dissolution, emulsion formation, or temperature-induced rheological changes). Designed for robustness and operational safety, the Eurostar 100 integrates a hardware-level safety circuit that triggers immediate shutdown upon motor stall or thermal overload—compliant with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. Its compact footprint (under 250 mm height), cast aluminum housing with thermoplastic polymer coating, and optimized acoustic damping support integration into fume hoods, glove boxes, and regulated lab spaces where space, noise, and material compatibility are critical.

Key Features

• Brushless DC motor with 136 W maximum shaft output power and 100 N·cm peak torque—enabling reliable operation up to 70,000 mPa·s viscosity
• Closed-loop speed control with ±1 rpm setting accuracy (>300 rpm) and ±1% deviation (<300 rpm), maintaining setpoint stability under load variation
• Hollow stainless steel stirring shaft (11 mm internal diameter) allows simultaneous insertion of temperature probes (PT1000), pH electrodes, or sampling needles—even when stationary
• Dual-clamp compatibility: universal chuck accepts stirring elements from 0.5 mm to 10 mm diameter; accommodates overhead stirrers, anchor, paddle, and propeller geometries
• Digital model: LED 7-segment display, IP40-rated enclosure, silent operation (<55 dB(A)), and error-code diagnostics for rapid troubleshooting
• Control model: Full-color TFT touchscreen interface with multilingual support (EN, DE, FR, ES, CN), programmable ramp profiles, timer (1–6000 min), reversible rotation, and intermittent mode
• Integrated torque trend monitoring (Control model only)—provides real-time graphical representation of torque evolution, serving as an indirect indicator of viscosity change or reaction progress
• Wireless remote operation (up to 150 m line-of-sight range) and dual communication interfaces: RS232 and USB for data logging, parameter synchronization, and external system integration

Sample Compatibility & Compliance

The Eurostar 100 is validated for use with aqueous, organic, and semi-solid media across diverse chemical, pharmaceutical, and materials science applications. Its design supports ISO 8573-1 Class 4 compressed air compatibility (when used with pneumatic accessories), and its non-explosion-proof configuration aligns with standard laboratory environments per EN 60079-0. While not certified for cleanroom use (ISO 14644-1 Class 5+), its smooth, non-porous housing surfaces facilitate GMP-aligned cleaning protocols. All electrical components conform to CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). The Control model’s data logging functionality—including timestamped speed, torque, and temperature values—supports audit-ready documentation in GLP and 21 CFR Part 11-compliant workflows when paired with validated software (e.g., IKA Labworldsoft).

Software & Data Management

The Eurostar 100 Control integrates natively with IKA Labworldsoft v5.x—a validated PC application supporting method creation, multi-parameter acquisition (speed, torque, temperature), and export to CSV, PDF, or XML formats. Data integrity safeguards include electronic signatures, user access levels, and immutable audit trails for all parameter modifications and run events. Raw serial data streams (via RS232 or USB CDC class) are compatible with third-party platforms such as LabVIEW, MATLAB, or Python-based automation frameworks using standard ASCII command protocols (e.g., “SPEED=1200”, “TORQUE?”). No proprietary drivers are required for USB connectivity. Temperature measurement utilizes PT1000 sensors meeting DIN IEC 751 Class A tolerances (±0.5 K at 0 °C), with full-range capability from –10 °C to +350 °C and resolution of 0.1 K.

Applications

• Pharmaceutical formulation: Suspension stabilization, granulation fluid dynamics studies, and dissolution testing under controlled shear conditions
• Chemical synthesis: Exothermic reaction mixing, catalyst dispersion in viscous monomer systems, and polymerization initiation control
• Food & beverage R&D: Emulsion development (mayonnaise, dressings), starch gelatinization kinetics, and yeast propagation consistency testing
• Materials science: Nanoparticle dispersion in resins, ceramic slurry homogenization, and battery electrode slurry preparation
• Quality assurance labs: Reproducible viscosity benchmarking per ASTM D2196 or ISO 2557, batch-to-batch consistency verification, and equipment qualification (IQ/OQ)

FAQ

What is the difference between the Eurostar 100 Digital and Eurostar 100 Control models?

The Digital model features LED-based speed display and basic closed-loop regulation. The Control model adds a TFT touchscreen, bidirectional rotation, timer, torque trend visualization, wireless remote operation, and full RS232/USB data connectivity.
Can the Eurostar 100 be used for continuous 24/7 operation?

Yes—both models are rated for 100% duty cycle under ambient conditions of 5–40 °C and ≤80% relative humidity, provided adequate ventilation and mechanical load remain within specified torque and viscosity limits.
Is the hollow shaft compatible with all standard temperature probes?

It accepts any rigid probe with outer diameter ≤10.5 mm and sufficient rigidity to avoid deflection; PT1000 sensors with M6 or ¼” NPT threading are commonly deployed.
Does the device support GLP-compliant data archiving?

When used with IKA Labworldsoft under configured user roles and electronic signature settings, it fulfills core ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and supports 21 CFR Part 11 readiness through optional digital certificate integration.
What maintenance is required for long-term reliability?

No routine lubrication or carbon brush replacement is needed due to the brushless motor architecture. Annual verification of speed/torque calibration using traceable reference standards is recommended for regulated environments.
