IKA EUROSTAR 100 control Overhead Stirrer

Overview

The IKA EUROSTAR 100 control is a high-performance overhead stirrer engineered for precision mixing, dispersion, and homogenization in research laboratories, quality control environments, and pilot-scale process development. Designed around a brushless DC motor architecture, it eliminates carbon brush wear, ensuring long-term torque stability, low maintenance, and consistent rotational performance across its full speed range of 0/30–1300 rpm. Its core measurement principle relies on closed-loop electronic speed and torque feedback, enabling real-time monitoring and reproducible shear application—critical for rheologically sensitive formulations such as polymer solutions, suspensions, emulsions, and high-viscosity pastes. With a maximum rated torque of 100 N·cm and capacity to handle media up to 70,000 mPa·s, the unit supports scalable mixing from small-volume reaction vessels to 100 L jacketed reactors under continuous duty (100% duty cycle). The integrated hollow shaft design permits in-situ insertion of temperature probes or pH electrodes without interrupting agitation—a feature essential for kinetic studies and controlled exothermic reactions.

Key Features

• Brushless DC motor delivering high efficiency, low noise (<55 dB(A)), and extended service life without brush replacement
• TFT graphical display with multilingual interface (English, German, French, Spanish, Chinese, Japanese) supporting intuitive parameter navigation and real-time data visualization
• Precise electronic speed control with ±1 rpm setting resolution and calibrated deviation limits (±1% above 300 rpm; ±3 rpm below)
• Real-time torque monitoring with ±6 N·cm measurement accuracy and trend logging for detecting viscosity transitions or endpoint determination
• Programmable bidirectional rotation and intermittent stirring cycles for de-agglomeration, crystallization control, or sediment resuspension
• Integrated PT1000 temperature input with Class A accuracy per DIN EN 60751, enabling synchronized thermal–mechanical process control
• Wireless remote operation via WH 11 controller (up to 150 m line-of-sight range) for safe operation in fume hoods or segregated process areas
• Robust cast aluminum housing with thermoplastic coating, IP40-rated enclosure, and comprehensive safety logic including overload cut-off, stall detection, and error-code diagnostics

Sample Compatibility & Compliance

The EUROSTAR 100 control accommodates a broad spectrum of sample types—from low-viscosity aqueous buffers to non-Newtonian gels, thixotropic slurries, and thermally sensitive biopolymer solutions. Its 11 mm hollow shaft allows concurrent use of standardized laboratory probes (e.g., Pt1000, pH, DO) without mechanical interference. The system complies with key international electrical and operational standards, including DIN EN 61010-1 (safety requirements for laboratory equipment), DIN EN 61326-1 (EMC for measurement and control devices), and RoHS/REACH directives. While not intrinsically rated for hazardous area use, its design supports integration into GLP- and GMP-aligned workflows when paired with validated SOPs and audit-trail-capable software extensions.

Software & Data Management

Data acquisition and instrument control are enabled via native USB and RS232 interfaces, compatible with IKA’s labworldsoft® platform (v4.0+). This software provides full parameter logging—including speed, torque, temperature, time, and direction—with timestamped CSV export, configurable alarm thresholds, and user-access-level management. When deployed in regulated environments, labworldsoft® supports 21 CFR Part 11-compliant configurations (electronic signatures, audit trails, role-based permissions) upon validation. All firmware updates are delivered through IKA’s secure update portal, ensuring traceability and version control aligned with ISO/IEC 17025 documentation requirements.

Applications

• Kinetic studies requiring simultaneous temperature ramping and shear-controlled mixing (e.g., enzyme-catalyzed polymerizations)
• Pharmaceutical suspension formulation and granulation process development under cGMP-relevant conditions
• Materials science applications including nanoparticle dispersion in viscous matrices and rheological preconditioning of battery slurries
• Chemical synthesis involving gas–liquid mass transfer (e.g., hydrogenations) where precise impeller positioning and torque feedback optimize gas dispersion efficiency
• Food R&D for texture-modifying processes such as starch gelatinization or protein denaturation under controlled shear–thermal profiles
• Educational laboratories demonstrating Newtonian vs. non-Newtonian fluid behavior using calibrated viscosity standards

FAQ

What is the maximum vessel size supported by the EUROSTAR 100 control?

It is rated for stirring volumes up to 100 L of water-equivalent media; actual capacity depends on viscosity, impeller geometry, and vessel aspect ratio.
Can the unit operate unattended for extended periods?

Yes—designed for continuous 100% duty cycle operation with integrated thermal management and automatic overload protection.
Is the PT1000 temperature probe included in the standard delivery?

Yes—the H 67.60 high-temperature probe (–50 to +350 °C) is supplied as standard equipment.
Does the WH 11 wireless controller require pairing or configuration?

No—it operates out-of-the-box with factory-matched encryption and supports immediate command transmission without driver installation.
How is calibration traceability maintained for torque and speed measurements?

IKA provides optional factory calibration certificates (ISO/IEC 17025-accredited) for speed and torque channels, with documented uncertainty budgets and reference standards traceable to national metrology institutes.
