IKA EUROSTAR 200 control Overhead Stirrer

Overview

The IKA EUROSTAR 200 control is a high-performance overhead stirrer engineered for precision mixing, dispersion, and homogenization tasks in research laboratories, quality control environments, and pilot-scale production settings. Designed around a brushless DC motor architecture, it eliminates carbon brush wear—ensuring long-term torque stability, reduced maintenance, and enhanced operational reproducibility across extended duty cycles. Its dual-speed-range configuration (6–400 rpm and 30–2000 rpm) enables optimal adaptation to both high-torque, low-speed viscous applications (e.g., polymer melts or pastes) and high-shear, low-viscosity processes (e.g., emulsification or catalyst suspension). The device operates with full 100% continuous duty capability and integrates real-time torque and temperature monitoring via a calibrated PT1000 sensor interface—supporting closed-loop process control where thermal feedback directly informs speed modulation strategies.

Key Features

• Brushless DC motor delivering consistent 84 W output power and peak torque of 200 N·cm (Range I) or 40 N·cm (Range II), ensuring stable rotational performance under variable load conditions
• High-resolution TFT display with multilingual support, showing real-time values for speed, torque, temperature, elapsed time, and system status codes
• Stepless electronic speed control with ±1 rpm setting accuracy and traceable speed measurement deviation (±1% above 300 rpm; ±3 rpm below)
• Hollow shaft design (10.3 mm internal diameter) permitting insertion of temperature probes or sampling tools without interrupting agitation
• Integrated timer function (1–6000 minutes) supporting programmable intermittent operation sequences for reaction kinetics studies or controlled shear history experiments
• Dual communication interfaces (RS232 and USB) enabling seamless integration into laboratory information management systems (LIMS) and automated workflows
• IP40-rated enclosure constructed from cast aluminum and thermoplastic polymer—optimized for mechanical rigidity, thermal dissipation, and chemical resistance in standard lab environments
• WH 11 wireless controller included as standard, enabling remote operation up to 150 m (line-of-sight dependent), reducing operator exposure during hazardous or high-temperature procedures

Sample Compatibility & Compliance

The EUROSTAR 200 control accommodates vessels from small beakers (≥50 mL) to large reactors (up to 100 L water-equivalent volume), compatible with glass, stainless steel, and chemically resistant polymer containers. Its clamp system accepts stirring shafts from 0.5 mm to 10 mm diameter—including PTFE-coated, glass, and Hastelloy variants—supporting applications involving aggressive solvents, elevated temperatures (–10 °C to +350 °C), or abrasive suspensions. Temperature measurement complies with DIN EN 60751 Class A specifications, ensuring metrological traceability for GLP/GMP-aligned documentation. While not intrinsically rated for explosion-proof zones, its electrical architecture meets IEC 61010-1 safety requirements for laboratory equipment. The device supports audit-ready data logging when paired with IKA Labworldsoft software, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user authentication and event-trail logging.

Software & Data Management

When connected to a host PC via USB or RS232, the EUROSTAR 200 control is fully controllable and monitorable using IKA Labworldsoft—a validated platform for method development, parameter archiving, and export-compliant reporting (CSV, PDF, XML). All operational parameters—including speed ramps, torque thresholds, temperature setpoints, and timer events—can be preconfigured, saved as reusable methods, and recalled with one click. The software enforces role-based access control, generates timestamped audit trails for all parameter changes and manual interventions, and supports automated calibration certificate generation per ISO/IEC 17025 guidelines. Raw data streams (speed, torque, temperature, time) are continuously logged at user-defined intervals (down to 100 ms resolution), facilitating post-hoc rheological analysis or correlation with inline spectroscopic measurements.

Applications

• Viscosity-dependent process optimization in pharmaceutical suspension formulation and tablet coating slurry preparation
• Controlled crystallization studies requiring precise shear rate modulation and in situ temperature feedback
• Homogenization of nanocomposite dispersions where particle agglomeration must be minimized through gentle yet consistent agitation
• Chemical synthesis under reflux or inert atmosphere, leveraging hollow-shaft probe insertion for real-time reaction monitoring
• Quality assurance testing of adhesives, sealants, and greases per ASTM D2196 or ISO 2557 standards
• Bioreactor inoculation and media blending where sterility maintenance necessitates minimal vessel opening and remote actuation

FAQ

Can the EUROSTAR 200 control operate continuously at maximum torque?
Yes—it is rated for 100% continuous duty at full output, provided ambient conditions remain within 5–40 °C and relative humidity does not exceed 80%. Thermal management is ensured by passive convection from its cast-aluminum housing.
Is the PT1000 temperature sensor included in the base configuration?
Yes—the H 67.60 probe is supplied as standard equipment, calibrated to DIN EN 60751 Class A tolerance limits.
Does the device support external analog signal input for cascade control?
No—only digital communication via RS232/USB is supported; analog input for external PID feedback loops is not implemented.
What is the maximum permissible shaft length for stable operation?
For optimal dynamic balance and bearing longevity, IKA recommends limiting total shaft length (including extension arm and impeller) to ≤600 mm when operating above 1000 rpm.
How is overload protection implemented?
The unit features hardware-level current limiting and thermal cut-off circuitry that triggers immediate deceleration upon sustained torque exceeding 200 N·cm (Range I) or 40 N·cm (Range II), followed by error-code display and audible alert.
