IKA EUROSTAR 2000 Basic High-Performance Mechanical Stirrer

Overview

The IKA EUROSTAR 2000 Basic is a high-torque, microprocessor-controlled mechanical stirrer engineered for reproducible mixing of low- to high-viscosity liquids in research, quality control, and production laboratories. Designed according to Couette flow principles—where shear rate is defined by rotational speed, impeller geometry, and fluid rheology—the instrument delivers precise, continuous agitation without gear-based speed stepping. Its brushless motor architecture ensures stable rotational output across the full 50–2000 rpm range, with constant torque delivery (60 N·cm) maintained up to 1000 rpm—critical for viscous polymer solutions, suspensions, and emulsions requiring sustained mechanical energy input. The hollow shaft design (11 mm internal diameter) allows insertion of temperature probes or pH electrodes during operation, supporting real-time process monitoring without interrupting agitation. Built to DIN EN 60529 standards with IP 42 ingress protection, the unit operates reliably under standard laboratory ambient conditions (5–40 °C, ≤80% RH) and supports uninterrupted duty cycles (100% S1 rating), making it suitable for extended batch processing.

Key Features

• Microprocessor-controlled speed regulation enabling smooth, stepless adjustment from 50 to 2000 rpm with ±1% speed accuracy
• High-output brushless motor delivering 110 W nominal power and consistent 60 N·cm torque across low-to-mid speed ranges (up to 1000 rpm)
• Hollow stainless-steel stirring shaft (11 mm bore) permitting in-situ sensor integration during active mixing
• Universal chuck with 0.5–10 mm clamping range and quick-release mechanism for rapid impeller exchange
• Analog output (0–10 V) for external speed signal logging or integration into centralized lab control systems
• Integrated thermal and electronic overload protection circuits compliant with IEC 61000-6-2/6-4 EMC requirements
• Compact footprint (80 × 253 × 190 mm) and low-noise operation (<65 dB(A)) optimized for benchtop use in shared lab environments
• Robust aluminum housing with reinforced mounting interface compatible with IKA R 1822 support arms and universal lab stands

Sample Compatibility & Compliance

The EUROSTAR 2000 Basic accommodates aqueous, organic, and semi-solid media up to 40 L volume (water-equivalent) and viscosities up to 50,000 mPa·s—enabling homogenization of hydrogels, ceramic slurries, adhesives, and pharmaceutical suspensions. Its mechanical design conforms to ISO 8573-1 (compressed air purity) for cleanroom-adjacent applications and meets general-purpose safety requirements per EN 61010-1:2019 (Laboratory Equipment Safety). While not intrinsically rated for explosive atmospheres, its non-sparking motor and grounded chassis support safe operation in standard chemical handling environments. The unit is routinely deployed in GLP-compliant labs where traceability of mixing parameters is enforced via analog output logging; however, it does not include FDA 21 CFR Part 11–compliant audit trail functionality natively.

Software & Data Management

This model operates as a standalone analog-controlled device without embedded firmware-based data storage or USB/RS232 connectivity. Speed setpoints are indicated via calibrated analog dial (no digital display), and operational parameters are recorded externally using compatible chart recorders or DAQ systems interfaced via the 0–10 V analog output port. For laboratories requiring digital parameter capture, IKA recommends pairing the EUROSTAR 2000 Basic with third-party data acquisition hardware and validated software platforms such as LabVIEW or MATLAB, configured to sample analog voltage signals and convert them to RPM values using the provided linear scaling factor (10 V = 2000 rpm). No proprietary drivers or cloud synchronization are supported.

Applications

• Preparation of high-viscosity formulations in pharmaceutical development (e.g., ointments, gels, and sustained-release suspensions)
• Mixing of catalyst slurries and metal-organic frameworks (MOFs) in materials science synthesis workflows
• Homogenization of food-grade thickeners, starch pastes, and dairy emulsions under controlled thermal conditions
• Standardized dispersion of nanoparticles in solvent matrices prior to DLS or TEM analysis
• Batch-wise dilution and reconstitution of lyophilized biologics in QC release testing
• Supporting ASTM D2196 and ISO 2557-2 viscosity benchmarking protocols when coupled with standardized impellers and calibrated vessels

FAQ

Does the EUROSTAR 2000 Basic include a digital display or programmable memory?

No. It features an analog speed dial with fixed calibration marks and no internal memory or user-programmable profiles.
Is the unit compatible with IKA’s R 182 clamp and R 1822 support arm?

Yes. It mounts directly to the R 1822 vertical extension arm (200 mm length, 16 mm diameter) using the integrated M10 threaded base.
Can the hollow shaft accommodate PT100 or thermocouple probes during operation?

Yes—standard 6 mm-diameter probes fit within the 11 mm bore; ensure probe sheath material is chemically compatible with the process medium.
What impeller types are recommended for viscosities above 20,000 mPa·s?

Helical ribbon or anchor-type impellers (e.g., IKA 2657700S) are advised to maximize axial flow and minimize vortex formation in highly viscous systems.
Does the device meet CE marking requirements for export to the European Economic Area?

Yes. It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), verified by TÜV Rheinland test report number available upon request.
