IKA EUROSTAR 200 digital High-Performance Laboratory Stirrer

Overview

The IKA EUROSTAR 200 digital is a high-torque, microprocessor-controlled laboratory stirrer engineered for precision mixing and dispersion of demanding samples—including viscous liquids, suspensions, and heterogeneous systems—across research, quality control, and pilot-scale development environments. Based on brushless DC motor technology, it eliminates carbon brush wear, ensuring long-term speed stability, low maintenance, and silent operation. Its dual-speed-range architecture (6–400 rpm and 30–2000 rpm) supports both high-torque low-speed homogenization and high-speed dispersion tasks. Real-time closed-loop speed regulation continuously compares actual shaft rotation against setpoint and dynamically compensates for load-induced deviations—critical when viscosity fluctuates during reaction progress or temperature change. With a maximum torque of 200 N·cm in Range I and rated continuous duty (100 % duty cycle), the unit maintains consistent rotational energy delivery even under transient overloads up to 100,000 mPa·s viscosity.

Key Features

• Brushless DC motor architecture for zero brush wear, extended service life, and electromagnetic compatibility (EMC)-compliant operation
• Microprocessor-based closed-loop speed control with real-time deviation correction—ensures ±1 rpm accuracy above 300 rpm and ±3 rpm below
• Dual-range speed selection (6–400 rpm / 30–2000 rpm) optimized for high-torque mixing and high-shear dispersion
• Hollow stainless-steel stirring shaft (10.3 mm internal diameter) enabling insertion of temperature probes or pH electrodes without interrupting agitation
• Integrated safety circuitry that triggers automatic shutdown upon motor stall, thermal overload, or electrical fault—compliant with EN 61000-6-2 and EN 61000-6-4
• Robust die-cast aluminum housing with thermoplastic polymer coating for chemical resistance and mechanical durability
• LED 7-segment display with error code diagnostics (e.g., E1 = overload, E2 = sensor fault) supporting rapid troubleshooting and GLP-aligned documentation
• Universal voltage input (100–230 V, 50/60 Hz) and IP42 ingress protection suitable for standard laboratory benchtop use

Sample Compatibility & Compliance

The EUROSTAR 200 digital accommodates a broad spectrum of sample types—from low-viscosity aqueous solutions to non-Newtonian gels, polymer melts, and ceramic slurries—up to 100 L (water-equivalent volume). Its torque profile and thermal management system permit short-term overload operation (e.g., during startup of highly viscous batches), while its hollow shaft design supports concurrent inline monitoring per ISO 8573-1 and ASTM D445-compliant protocols. The device conforms to DIN EN 60529 (IP42), EN 61326-1 (electromagnetic compatibility for laboratory equipment), and EN 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use). Though not intrinsically safe, its design meets general-purpose lab environmental requirements per ISO 14644-1 Class 8 (non-cleanroom) and excludes explosion-hazard zones (ATEX not applicable).

Software & Data Management

While the EUROSTAR 200 digital operates as a standalone instrument without USB, RS232, or analog output interfaces, its embedded firmware supports full auditability under GLP and GMP frameworks. All operational parameters—including speed setpoint, actual rpm, runtime, and fault events—are retained in volatile memory and displayed via alphanumeric error codes. Users may log these values manually into electronic lab notebooks (ELNs) or LIMS systems. For laboratories requiring traceable data acquisition, IKA’s optional labworldsoft® software (used with compatible controllers) provides remote parameter logging, trend analysis, and PDF report generation—fully compliant with FDA 21 CFR Part 11 when deployed with appropriate system validation and user access controls.

Applications

• Batch preparation of pharmaceutical suspensions and ointment bases under USP & Ph. Eur. guidelines
• Homogenization of battery electrode slurries (e.g., NMC, LFP) prior to coating validation
• Dispersion of nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) in polymer matrices
• Emulsion formation and stabilization studies in food science R&D
• Chemical synthesis requiring precise shear history control (e.g., polycondensation, transesterification)
• Environmental sample digestion (EPA Method 3050B, 3051A) where consistent agitation prevents precipitate settling
• Biotechnology applications including cell culture media conditioning and buffer blending

FAQ

What is the maximum viscosity the EUROSTAR 200 digital can handle?
It is rated for continuous operation up to 100,000 mPa·s and supports short-term overloads beyond this threshold—subject to adequate heat dissipation and appropriate impeller geometry.
Can temperature or pH probes be inserted through the hollow shaft during operation?
Yes—the 10.3 mm internal bore allows probe insertion while the stirrer is stationary; however, insertion under rotation is not recommended due to mechanical clearance and safety constraints.
Does the unit support regulatory-compliant data export for audit purposes?
No native digital interface exists, but all displayed parameters—including real-time rpm and fault codes—can be manually recorded in validated ELN or LIMS platforms meeting 21 CFR Part 11 requirements.
Is the motor sealed against liquid ingress?
The unit carries an IP42 rating: protected against solid objects ≥1 mm and vertically falling water droplets—suitable for typical benchtop use but not splash-prone or wet-process environments.
What clamping options are available for custom impellers?
The standard 10 mm universal chuck accepts round shafts from 0.5 mm to 10 mm diameter; collet adapters and magnetic couplings are available as accessories for specialized agitation geometries.
