IKA Eurostar 200 Digital & Control Stirrers

Overview

The IKA Eurostar 200 series comprises two high-performance laboratory stirrers—Digital and Control variants—engineered for precision mixing, dispersion, and homogenization of low- to extremely high-viscosity samples in R&D, quality control, and production environments. Based on brushless DC motor technology, both models deliver exceptional torque stability, thermal efficiency, and long-term operational reliability without carbon brush wear or commutation noise. The core operating principle relies on closed-loop speed regulation via microprocessor-controlled feedback: real-time comparison between setpoint and actual shaft speed enables dynamic correction, ensuring consistent rotational velocity even during viscosity fluctuations—critical for reproducible shear history in polymer solutions, suspensions, pastes, and emulsions. With a maximum torque output of 200 N·cm in low-speed range (6–400 rpm), the Eurostar 200 is uniquely suited for demanding applications such as solvent-free resin blending, ceramic slurry deagglomeration, and pharmaceutical ointment formulation—where mechanical robustness and speed fidelity directly impact product consistency and batch-to-batch comparability.

Key Features

• Brushless DC motor architecture ensures maintenance-free operation, low electromagnetic interference, and high energy conversion efficiency (99 W mechanical output from 121 W electrical input)
• Dual-speed-range design: Range I (6–400 rpm) optimized for high-torque, low-speed mixing; Range II (30–2000 rpm) for rapid dispersion and low-viscosity homogenization
• Closed-loop speed control with ±1 rpm setting accuracy (>300 rpm) and ±1% deviation (<300 rpm), enabling GLP-compliant documentation of shear rate profiles
• Hollow stainless-steel shaft (ID 10.3 mm) allows insertion of temperature probes, pH electrodes, or sampling needles without interrupting agitation
• Integrated safety circuit halts operation instantly upon motor stall or thermal overload—compliant with EN 61000-6-2 (immunity) and EN 61000-6-4 (emission) standards
• Digital model features LED 7-segment display, error-code diagnostics, and silent operation (<55 dB(A) at 1 m)
• Control model adds TFT touchscreen interface, multilingual UI (EN/DE/FR/ES), programmable protocols, torque trend visualization, and real-time temperature monitoring via PT1000 input
• Full RS232 and USB connectivity (Control only) supports bidirectional communication with PC-based lab software for automated method execution, audit-trail generation, and 21 CFR Part 11–compliant data archiving

Sample Compatibility & Compliance

The Eurostar 200 accommodates vessels from 50 mL beakers to 100 L jacketed reactors, supporting standard impeller types (e.g., paddle, anchor, propeller, and helical ribbons) via a precision 10 mm keyed chuck (0.5–10 mm clamping range). Its 200 N·cm maximum torque enables stable agitation of non-Newtonian fluids up to 100,000 mPa·s—validated per ISO 2555 for apparent viscosity determination under defined shear conditions. While not certified for hazardous area use (ATEX/IECEx), the unit meets general-purpose laboratory safety requirements per DIN EN 61010-1 and carries CE marking. The IP40 ingress protection rating confirms suitability for standard dry-lab environments but excludes wet-process or washdown applications. All electronic subsystems comply with EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU.

Software & Data Management

The Eurostar 200 Control integrates seamlessly with IKA Labworldsoft® v5.x and third-party SCADA systems via ASCII-based RS232 or USB CDC protocols. Experimental parameters—including set speed, actual speed, torque %, temperature, elapsed time, and fault logs—are timestamped and exportable in CSV or XML formats. Built-in torque trend analysis correlates mechanical load changes with rheological transitions (e.g., gelation onset, yield point detection), supporting ASTM D2196-compliant viscosity profiling. Audit trails record user ID, parameter modifications, start/stop events, and calibration timestamps—fully traceable for FDA 21 CFR Part 11 and EU Annex 11 validation. No proprietary drivers are required; native Windows/Linux/macOS compatibility ensures deployment across heterogeneous IT infrastructures.

Applications

• Pharmaceutical: Wet granulation process development, topical gel base preparation, and suspension stabilization under controlled shear
• Chemicals: Polyurethane pre-polymer synthesis, pigment dispersion in coatings, and silicone elastomer curing kinetics studies
• Food & Beverage: High-solids batter mixing, dairy protein aggregation monitoring, and starch gelatinization profiling
• Academia & Materials Science: Nanoparticle suspension homogenization, hydrogel crosslinking quantification, and rheo-optical coupling experiments
• Quality Assurance: Batch release testing per USP (Viscosity of Semisolids) and ISO 1628-1 (Polymers in solution)

FAQ

What distinguishes the Eurostar 200 Digital from the Control version?

The Digital model provides core closed-loop speed control and LED display, while the Control variant adds TFT touchscreen, temperature monitoring (PT1000), torque trend visualization, programmable timers, RS232/USB interfaces, and full PC integration capabilities.
Can the Eurostar 200 be used for continuous 24/7 operation?

Yes—rated for 100% duty cycle under ambient conditions of 5–40 °C and ≤80% RH. Thermal management is passive; no forced cooling is required.
Is the hollow shaft compatible with all standard probe types?

It accepts any rigid probe with outer diameter ≤10 mm, including calibrated PT1000 sensors, conductivity cells, and optical density probes—provided mechanical clearance and chemical compatibility are verified.
Does IKA provide validation documentation for GMP environments?

Factory-issued IQ/OQ protocols, traceable calibration certificates (ISO/IEC 17025 accredited), and risk assessments are available upon request for regulated users.
What impeller geometries are recommended for >50,000 mPa·s media?

Anchor or helical ribbon impellers with close-clearance design (gap <5% vessel diameter) are advised to ensure bulk motion and avoid stagnant zones in highly viscous systems.
