IKA EUROSTAR 200 control P4 Overhead Stirrer

Overview

The IKA EUROSTAR 200 control P4 is a high-performance, microprocessor-driven overhead stirrer engineered for precision mixing and dispersion tasks in demanding laboratory environments. Designed around a brushless DC motor architecture, it eliminates carbon brush wear and delivers consistent torque output across its full operational range—critical for reproducible rheological behavior in non-Newtonian or shear-thinning systems. Its dual-speed-range capability (Range I: 4–108 rpm; Range II: 16–530 rpm) enables optimal matching of rotational energy to sample viscosity, while the real-time closed-loop speed regulation continuously compares actual shaft speed against setpoint and compensates for load-induced deviations—ensuring stable agitation even during dynamic viscosity shifts. The unit integrates a calibrated PT1000 temperature sensor (DIN IEC 751 Class A) for simultaneous thermal monitoring, supporting process-critical applications where temperature-dependent viscosity or reaction kinetics must be tracked. With a maximum torque output of 660 N·cm and rated torque of 6.6 N·m, the EUROSTAR 200 control P4 is validated for continuous-duty operation (100% duty cycle) in volumes up to 100 L of water-equivalent media, making it suitable for scale-up studies, formulation development, and quality control workflows under GLP-compliant conditions.

Sample Compatibility & Compliance

The EUROSTAR 200 control P4 accommodates a broad spectrum of sample types—from low-viscosity aqueous solutions to highly viscous pastes (up to 150,000 mPa·s). Its universal chuck (0.5–10 mm clamping range) supports standard ISO 867 and DIN 12879-compatible impellers, anchors, and helical blades. For regulatory-sensitive environments, the device meets essential electrical safety standards per EN 61010-1 and electromagnetic compatibility per EN 61326-1. While not intrinsically safe or ATEX-certified, its design complies with general-purpose laboratory use requirements under ISO/IEC 17025-accredited facilities. Data logging via RS232/USB supports audit trails compatible with FDA 21 CFR Part 11 when paired with validated third-party software, facilitating traceability in pharmaceutical, cosmetic, and food-grade QC laboratories.

Software & Data Management

The stirrer communicates natively with IKA’s Labworldsoft platform (v5.0+), enabling remote parameter configuration, real-time graphing of speed/torque/temperature profiles, and automated export of CSV-formatted datasets. All operational events—including error codes, safety interventions, and manual overrides—are timestamped and stored locally on the device’s internal memory. USB mass storage mode allows direct firmware updates and log file retrieval without auxiliary software. For integration into centralized LIMS or MES infrastructures, ASCII protocol documentation is provided under NDA, permitting custom API development. Audit trail functionality includes user ID tagging (via optional RFID login module), change history logging, and electronic signature support where aligned with site-specific 21 CFR Part 11 validation protocols.

Applications

• High-viscosity polymer solution homogenization (e.g., PVP, HPMC, xanthan gum dispersions)
• Emulsion and suspension stabilization in pharmaceutical preformulation studies
• Catalyst slurry mixing for heterogeneous reaction screening
• Thermal curing process monitoring via concurrent torque–temperature correlation
• QC testing of adhesives, sealants, and battery electrode slurries per ASTM D1847 and ISO 2557
• Scale-down validation of pilot-scale mixing processes in biopharmaceutical downstream processing
• Environmental sample digestion (EPA Method 3050B) requiring precise temperature–agitation coordination

FAQ

Does the EUROSTAR 200 control P4 support GLP-compliant data integrity?
Yes—when used with validated Labworldsoft configurations and enabled audit trail settings, it satisfies core ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) for electronic records.
Can the device operate unattended overnight?
Yes, provided ambient conditions remain within 5–40 °C and relative humidity ≤80%; the 100% duty cycle rating and thermal shutdown safeguards enable extended autonomous runs.
Is external temperature probe calibration traceable to national standards?
The integrated PT1000 sensor is factory-calibrated to DIN IEC 751 Class A; users may perform field verification using certified reference baths (e.g., Fluke 724) with documented uncertainty budgets.
What impeller geometries are recommended for >50,000 mPa·s media?
Anchor or helical ribbon impellers with close-clearance clearance (≤5 mm) and low tip speed (<1.5 m/s) are advised to minimize shear degradation and vortex formation.
How is torque measurement validated across speed ranges?
Torque accuracy is specified as ±60 N·cm in Range I and ±10 N·cm in Range II, verified at multiple setpoints using NIST-traceable torque transducers during final QA testing.
