IKA Eurostar 60 Digital & Control Stirrers

Overview

The IKA Eurostar 60 series comprises two high-precision laboratory stirrers engineered for reproducible mixing and dispersion across diverse sample matrices—from low-viscosity aqueous solutions to highly structured non-Newtonian fluids. Both the Digital and Control variants operate on a brushless DC motor architecture, eliminating carbon brush wear and ensuring long-term speed stability, low electromagnetic interference, and maintenance-free operation. The core control principle employs microprocessor-based closed-loop feedback: real-time comparison of actual shaft speed (measured via integrated optical encoder) against user-defined setpoints enables continuous torque compensation—critical for maintaining consistent shear rates during viscosity transitions. This dynamic regulation is essential for applications requiring strict process fidelity, such as polymer dissolution, suspension homogenization, or kinetic reaction monitoring where rheological changes directly impact mass transfer and reaction yield.

Key Features

• Brushless DC motor with 126 W mechanical output power and 60 N·cm maximum torque—optimized for sustained load handling up to 50,000 mPa·s.
• Closed-loop speed control with ±1 rpm setting accuracy above 300 rpm and ±1% deviation below 300 rpm—ensuring compliance with GLP documentation requirements for parameter traceability.
• Hollow shaft design (11 mm internal diameter) allows in-situ insertion of temperature probes, pH electrodes, or sampling needles without interrupting agitation—enabling true simultaneous measurement and mixing.
• Digital variant features LED 7-segment display, overload safety circuitry, error-code diagnostics, and silent operation (<50 dB(A)) in compact footprint (86 × 248 × 208 mm).
• Control variant adds full-featured TFT touchscreen interface with multilingual support, programmable protocols (including ramp profiles and hold steps), real-time torque trend visualization, and integrated timer (1–6000 min).
• RS232 and USB interfaces enable bidirectional communication with LIMS or custom LabVIEW/Python scripts for automated data logging, remote start/stop, and audit-ready export of timestamped speed/torque/temperature histories.
• Robust housing constructed from powder-coated die-cast aluminum and thermoplastic polymer—designed for chemical resistance and mechanical durability in ISO Class 8 cleanroom-adjacent environments (though not certified for ISO 5 or higher).

Sample Compatibility & Compliance

The Eurostar 60 accommodates standard laboratory vessels ranging from 10 mL beakers to 40 L jacketed reactors. Its universal chuck (0.5–10 mm clamping range) secures common stirring elements—including PTFE-coated rods, dissolving impellers, anchor paddles, and turbine blades—without slippage under transient load spikes. While not intrinsically safe or ATEX-certified, its IP40 ingress protection meets basic laboratory dust resistance per DIN EN 60529. For regulated environments, the Control model supports 21 CFR Part 11-compliant workflows when paired with validated software: electronic signatures, audit trails for parameter modifications, and immutable export of raw torque/time/temperature datasets are achievable through IKA’s labworldsoft platform (v5.0+). All units comply with EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.

Software & Data Management

The Eurostar 60 Control integrates natively with IKA labworldsoft, a GxP-aligned desktop application supporting method creation, execution scheduling, and real-time graphing of torque vs. time—a proxy for relative viscosity evolution during gelation or crosslinking. Data exports conform to ASTM E2500-13 (Standard Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems) via CSV or PDF reports with embedded metadata (operator ID, instrument serial number, calibration status). USB mass storage mode permits direct firmware updates and configuration backup without proprietary drivers. No cloud dependency: all processing occurs locally, preserving data sovereignty required by GDPR and HIPAA-aligned institutions.

Applications

• Quality control of pharmaceutical suspensions and emulsions (USP <701> uniformity of dosage units).
• Rheological profiling of adhesives, coatings, and battery slurries during formulation development.
• Controlled dissolution testing per USP Apparatus II (paddle method) with precise shear-rate replication.
• Bioreactor seed train preparation where oxygen transfer efficiency depends on consistent vortex geometry.
• Materials science labs performing solvent-based nanoparticle dispersion prior to DLS or SEM analysis.
• Academic research in colloid chemistry requiring uninterrupted 100%-duty-cycle operation over multi-hour kinetics experiments.

FAQ

Does the Eurostar 60 support reversible rotation?
No. Rotation is unidirectional only, optimized for standard impeller hydrodynamics and torque consistency.
Can the Digital model accept external temperature sensors?
No. Temperature sensing is exclusive to the Control variant via its PT1000 input port.
Is continuous operation at maximum torque rated for indefinite duration?
Yes—rated for 100% duty cycle at ambient temperatures ≤40 °C and relative humidity ≤80 %, provided adequate ventilation around the base unit.
What is the minimum detectable torque change on the Control model?
The system resolves torque increments of 0.1 N·cm, with full-scale measurement uncertainty of ±6 N·cm per DIN ISO 376 calibration standards.
Are replacement chucks and shafts available as spare parts?
Yes. IKA offers standardized accessories including stainless steel hollow shafts (Cat. No. 0000000001), quick-release chucks (Cat. No. 0000000002), and autoclavable PTFE-coated impellers—each supplied with CE-conformity declarations.
