IKA Eurostar Power Control Overhead Stirrer

Overview

The IKA Eurostar Power Control is a high-performance overhead stirrer engineered for precision mixing and dispersion of medium-to-high viscosity samples in research laboratories, quality control environments, and pilot-scale development workflows. Designed around a brushless DC motor architecture and microprocessor-based closed-loop speed regulation, this instrument delivers consistent rotational performance independent of load fluctuations—critical when processing shear-thinning or thixotropic fluids such as polymer solutions, suspensions, pastes, and emulsions. Unlike gear-driven systems, its electronic speed control enables true stepless adjustment across the full 50–2000 rpm range, eliminating mechanical wear and ensuring long-term repeatability. The unit’s robust torque delivery—up to 60 N·cm at low speeds—is maintained even under sustained overload conditions, supporting continuous operation (100% duty cycle) without thermal derating. Its compact footprint, quiet operation (<65 dB(A)), and integrated safety features—including automatic torque cutoff, stall detection, and fail-safe circuitry—make it suitable for unattended use in regulated laboratory settings.

Key Features

• Microprocessor-controlled, brushless DC motor with real-time speed and torque feedback
• True infinitely variable speed control (50–2000 rpm) without mechanical gear shifting
• Dual-display LCD showing setpoint and actual speed, plus dynamic torque trend visualization
• Integrated analog output (0–10 V) and RS232 interface for external data logging and remote parameter adjustment
• Hollow shaft design (11 mm inner diameter) enabling simultaneous insertion of temperature probes, pH electrodes, or sampling needles during operation
• Self-centering chuck with 0.5–10 mm clamping range; compatible with standard ISO 8687-1 stirring elements
• IP42-rated enclosure providing protection against solid objects >1 mm and vertically falling water droplets
• Full torque monitoring with overload indication and automatic shutdown at preset thresholds
• Stainless-steel support arm (16 mm Ø, 200 mm length) with universal mounting interface for integration into fume hoods or custom rigs

Sample Compatibility & Compliance

The Eurostar Power Control accommodates a broad spectrum of sample types—from low-viscosity aqueous buffers to highly viscous non-Newtonian materials up to 50,000 mPa·s. Its stable torque curve across speed ranges ensures reliable homogenization of heterogeneous mixtures, including ceramic slurries, pharmaceutical gels, food pastes, and battery electrode slurries. The device complies with DIN EN 60529 (IP42), EN 61000-6-3 (EMC emissions), and EN 61000-6-2 (immunity). When used with validated labworldsoft® software, it supports audit-trail-enabled operation aligned with GLP and GMP documentation requirements. While not intrinsically rated for hazardous areas, its electrical isolation and thermal management meet general-purpose laboratory safety standards per IEC 61010-1.

Software & Data Management

The stirrer integrates seamlessly with IKA’s labworldsoft® software via RS232 connection, enabling full remote control, parameter scripting, and time-synchronized acquisition of speed, torque, and elapsed runtime. Data export is supported in CSV and XML formats for downstream analysis in MATLAB®, Python, or LIMS platforms. The analog output channel permits direct interfacing with chart recorders or PLC-based process controllers. All configuration changes are timestamped and logged within the software environment, satisfying traceability needs for ISO/IEC 17025-accredited labs. Firmware updates are performed over serial link, preserving calibration integrity and ensuring continued compliance with evolving regulatory expectations.

Applications

• Rheological conditioning of polymer melts and thermoplastic resins prior to extrusion or injection molding trials
• Homogenization of active pharmaceutical ingredient (API) suspensions in oral liquid formulations
• Dispersion of nanomaterials (e.g., graphene oxide, metal oxides) in solvent matrices under inert atmosphere
• Preparation of uniform catalyst slurries for fixed-bed reactor testing
• Controlled agitation during crystallization studies where nucleation kinetics are sensitive to shear history
• Batch-scale mixing of cosmetic emulsions requiring precise temperature and shear profile control
• Environmental sample preparation—including sediment resuspension and leachate homogenization—for EPA Method-compliant analysis

FAQ

Is the Eurostar Power Control compatible with third-party software?
Yes—through its standardized RS232 protocol and documented command set, it can be integrated with custom LabVIEW, Python, or C# applications using ASCII-based SCPI-like instructions.
Can the hollow shaft accommodate PT100 sensors during operation?
Yes—the 11 mm internal diameter allows standard 6 mm OD PT100 probes to be inserted while stirring, provided the probe is chemically compatible and mechanically secured.
Does the unit require periodic recalibration?
No routine recalibration is required; torque and speed sensors are factory-calibrated and drift-compensated in firmware. Verification against NIST-traceable reference standards is recommended annually in regulated environments.
What is the maximum permissible ambient humidity for continuous operation?
Operation is rated for up to 80 % relative humidity at 31 °C, non-condensing, per DIN EN 60529 IP42 specifications.
How is overload protection implemented?
A real-time current-monitoring algorithm detects excessive motor load; if torque exceeds 60 N·cm for >2 seconds, the drive enters safe stop mode and displays an error code on the LCD.
