IKA Eurostar Digital Overhead Stirrer T_2072600025

Overview

The IKA Eurostar Digital Overhead Stirrer T_2072600025 is a high-performance, microprocessor-controlled mechanical stirring system engineered for precision and reproducibility in demanding laboratory environments. Unlike magnetic stirrers, this overhead design employs direct-drive torque transmission via interchangeable stirrer shafts and impellers—enabling reliable mixing of high-viscosity fluids, heterogeneous suspensions, and shear-sensitive formulations where magnetic coupling fails. Its robust brushless DC motor delivers consistent torque across the full speed range (50–2000 rpm), supporting both low-shear homogenization and high-torque dispersion tasks. The device operates on the principle of rotational mechanical agitation, where torque is transmitted through a vertically mounted drive shaft to an impeller or anchor-type agitator immersed in the vessel—making it suitable for jacketed reactors, glass vessels, stainless-steel tanks, and custom reactor configurations up to 40 L capacity (with water-equivalent viscosity). Designed and manufactured in Staufen, Germany, the unit complies with CE marking requirements and adheres to ISO 9001 quality management standards throughout production.

Key Features

• Microprocessor-based digital speed control with real-time RPM feedback and ±1% speed accuracy
• Brushless DC motor delivering continuous torque up to 80 N·cm, optimized for viscous media up to 50,000 mPa·s
• Digital LED display showing actual rotational speed; no analog dials or manual calibration required
• Integrated overload protection and thermal shutdown safeguarding motor integrity during extended operation
• Ergonomic, compact housing with IP20-rated enclosure for benchtop stability and dust resistance
• Standardized 10 mm universal chuck (T_2072657700S R182) compatible with IKA’s full range of stirrer shafts and impellers (e.g., T_2070741000S R1342)
• Modular mounting system supporting vertical alignment on standard lab stands (e.g., T_2073160100 R1826) and vessel clamping (e.g., T_2073008600 RH3)

Sample Compatibility & Compliance

The Eurostar T_2072600025 accommodates a broad spectrum of sample types—including Newtonian and non-Newtonian liquids, polymer melts, ceramic slurries, pharmaceutical suspensions, and bioreactor broths—provided appropriate impeller geometry and shaft length are selected. It supports glass, stainless steel, and PTFE-lined vessels from 500 mL to 40 L nominal volume. As a standalone drive unit without integrated heating or cooling, it is routinely deployed in conjunction with external temperature control systems (e.g., circulators, jacketed reactors) in GLP-compliant QC labs and GMP-aligned pilot-scale development workflows. All electrical components meet CE, RoHS, and EMC Directive 2014/30/EU requirements. While the stirrer itself does not incorporate data logging or audit trail functionality, its analog/digital interface allows integration into validated process control networks when paired with third-party SCADA or LIMS-compatible acquisition modules.

Software & Data Management

This model operates as a stand-alone instrument with no embedded software or USB/Bluetooth connectivity. Speed settings are configured manually via front-panel controls and retained only during active operation—no parameter memory or recall function is included. For laboratories requiring electronic recordkeeping or 21 CFR Part 11 compliance, external data capture is achievable using optional analog output modules (e.g., 0–10 V signal for RPM) interfaced with validated DAQ systems. IKA’s LabWorldSoft platform does not support the T_2072600025 directly; however, users may integrate it into broader workflow automation via relay-triggered start/stop commands synchronized with other IKA devices (e.g., RV 10 rotary evaporators or C-MAG HS 7 heaters) in multi-step protocols.

Applications

• Scale-down formulation studies for adhesives, coatings, and composite resins under controlled shear conditions
• Preparation of uniform suspensions for analytical reference standards in pharmaceutical QA/QC
• Mixing of high-solids-content battery electrode slurries prior to coating trials
• Homogenization of microbial culture media in bioprocess development labs
• Dispersion of nanomaterials (e.g., graphene oxide, metal oxides) in solvent systems for materials science research
• Batch-wise agitation in ASTM D2196 or ISO 2557-2 viscosity test preparations
• Supporting USP <701> dissolution apparatus qualification through precise rotational consistency verification

FAQ

Does the Eurostar T_2072600025 include a built-in temperature control module?

No. This is a dedicated overhead stirring drive unit without heating or cooling capability. Temperature regulation must be achieved externally via jacketed vessels or immersion circulators.
Is the stirrer compatible with FDA-regulated GMP manufacturing environments?

Yes—when deployed as part of a validated system with documented IQ/OQ protocols, appropriate maintenance logs, and traceable calibration of speed output using NIST-traceable tachometers.
What impeller types are recommended for high-viscosity applications (>10,000 mPa·s)?

Anchor, helical ribbon, or double-helical impellers (e.g., IKA R1342 series) are advised to ensure radial and axial flow with minimal vortex formation and wall scraping efficiency.
Can this unit be mounted on a fume hood or reactor frame?

Yes—its standardized M12 threaded base and modular clamp accessories (e.g., T_2073160100 R1826 stand and T_2073008600 RH3 vessel clamp) enable secure, vibration-damped installation in ventilated enclosures or custom reactor rigs.
Does IKA provide calibration certificates with this model?

Factory calibration is performed per ISO/IEC 17025-accredited procedures; optional UKAS-traceable calibration certificates are available upon request at time of order.
