IKA EUROSTAR 400 control Overhead Stirrer

Overview

The IKA EUROSTAR 400 control is a high-performance overhead stirrer engineered for precision mixing, dispersion, and homogenization in demanding laboratory environments. Designed around a brushless DC motor architecture, it eliminates carbon brush wear, ensuring long-term torque stability, low maintenance, and silent operation across its full speed range of 6–2000 rpm. Its dual-range speed configuration—optimized for both high-torque, low-speed applications (e.g., polymer dissolution or suspension of dense particulates) and high-speed, low-viscosity blending—enables consistent shear delivery under dynamically changing rheological conditions. The unit continuously monitors actual shaft speed versus setpoint and applies real-time microprocessor-based PID regulation to maintain speed constancy—even during viscosity fluctuations exceeding several orders of magnitude. This closed-loop speed fidelity, combined with integrated torque trend analysis, transforms the EUROSTAR 400 control from a mechanical agitator into a quantitative process monitoring tool for reaction kinetics, gelation onset, or emulsion formation studies.

Key Features

• Brushless DC motor delivering 176 W continuous output power and peak torque up to 400 N·cm in low-speed range—ideal for viscous media up to 100,000 mPa·s
• Microprocessor-controlled speed regulation with ±1 rpm setting accuracy and automatic compensation for load-induced drift
• TFT graphical display supporting multilingual interface (English, German, French, Spanish, Chinese), real-time torque trend plotting, and error-code diagnostics
• Hollow shaft design (ID 10.3 mm) enabling simultaneous insertion of temperature probes, pH electrodes, or sampling tubes without interrupting agitation
• Integrated PT1000 temperature sensing (Class A per DIN EN 60751) with ±0.5 K accuracy and extended operational range (−10 to +350 °C) for exothermic/endothermic process monitoring
• Dual communication interfaces (RS232 and USB) compliant with IKA Labworldsoft™ software for remote parameter control, time-stamped data logging, and GLP-compliant audit trail generation
• Programmable timer (1–6000 min), intermittent operation mode, and configurable safety shutdown logic—including overload detection, stall protection, and thermal cutoff
• Modular mechanical design featuring IP40-rated cast aluminum housing, 16 mm diameter extension arm (160 mm length), and chuck-compatible shaft clamping (Ø 3–16 mm)

Sample Compatibility & Compliance

The EUROSTAR 400 control accommodates diverse sample types—from low-viscosity aqueous solutions to non-Newtonian gels, pastes, and filled suspensions—with maximum working volume of 150 L (water-equivalent). Its robust torque delivery supports common laboratory impellers (propeller, paddle, anchor, helical ribbon) and custom geometries mounted on standardized shafts. The system complies with key international safety and electromagnetic compatibility standards, including EN 61000-6-2 (immunity) and EN 61000-6-3 (emission), as well as EN 61010-1 for electrical safety in laboratory equipment. When used with validated protocols and Labworldsoft™ software, the instrument supports 21 CFR Part 11–aligned electronic recordkeeping, including user authentication, electronic signatures, and immutable audit trails required for GxP-regulated environments.

Software & Data Management

Control and data acquisition are fully supported via IKA Labworldsoft™—a Windows-based platform enabling synchronized logging of speed, torque, temperature, time, and calculated parameters (e.g., apparent viscosity trends). All measurement data are timestamped, stored in .csv or proprietary .ikad format, and exportable for statistical analysis or LIMS integration. The software supports method templates, multi-step protocols (e.g., ramp-hold-cool sequences), and automated report generation with customizable headers, units, and metadata fields. RS232 and USB connectivity ensure compatibility with legacy and modern lab infrastructure; no proprietary drivers are required for USB enumeration under Windows 10/11 or Linux kernel ≥5.4.

Applications

• Kinetic studies of polymerization, crosslinking, and sol-gel transitions via real-time torque profiling
• Scale-down mixing validation for pharmaceutical wet granulation and suspension formulation development
• High-shear dispersion of nanomaterials, pigments, or catalysts in solvent-based or aqueous media
• Temperature-controlled crystallization experiments with simultaneous agitation and in situ thermal monitoring
• Batch homogenization of biopharmaceutical buffers, cell culture media, or diagnostic reagents under sterile hood conditions
• Method transfer support between R&D, pilot-scale, and manufacturing environments through torque-based scalability modeling

FAQ

What is the maximum recommended vessel diameter for optimal mixing performance?
For uniform flow patterns and minimal vortexing, IKA recommends vessels with internal diameters between 100 mm and 500 mm when using standard impellers—scaling linearly with shaft length and impeller geometry.
Can the EUROSTAR 400 control be integrated into a PLC-controlled automated workstation?
Yes—via RS232 ASCII command protocol or optional analog I/O module (sold separately), enabling external start/stop, speed setpoint modulation, and status feedback in industrial automation frameworks.
Is the WH 11 wireless controller included with every unit?
Yes—the WH 11 handheld remote is supplied as standard equipment and operates reliably up to 150 m line-of-sight, supporting all primary functions including speed/torque/temperature adjustment and timer activation.
Does the system support calibration traceability to national standards?
Torque and temperature channels are factory-calibrated against certified reference standards; users may perform verification checks using NIST-traceable torque testers and PT1000 calibrators—documentation templates are provided in the user manual.
How is overload protection implemented during high-viscosity startup?
The drive electronics monitor current draw and rotational inertia deviation in real time; if torque demand exceeds 110 % of rated value for >2 s, the system initiates soft-stop deceleration and displays error code E07, preventing mechanical stress on geartrain or shaft couplings.
