Overview
The IKA EUROSTAR 20 High-Speed Digital Overhead Stirrer is an engineered solution for precise, reproducible mixing and dispersion tasks in research laboratories, quality control environments, and small-scale production settings. Designed around a brushless DC motor architecture, it eliminates carbon brush wear—ensuring long-term torque stability, minimal maintenance, and consistent rotational performance across its full 150–6000 rpm speed range. Its conical seat shaft interface guarantees axial alignment and concentricity during high-speed operation, reducing vibration-induced mechanical stress on both the drive unit and vessel contents. With a maximum output torque of 20 N·cm and rated power delivery of 125 W at the shaft, the EUROSTAR 20 supports demanding applications involving viscous media up to 10,000 mPa·s—such as polymer solutions, suspensions, emulsions, and ceramic slurries—while maintaining thermal stability under continuous duty.
Key Features
- Brushless DC motor technology for extended service life, zero brush dust contamination, and stable torque output across the entire speed range
- High-resolution LED display with 7-segment readout providing real-time feedback of actual rotational speed (±1 rpm setting accuracy)
- Stepless electronic speed control with dynamic compensation: measurement deviation remains within ±1 % above 300 rpm and ±3 rpm below 300 rpm
- Integrated overload protection system enabling short-term overtorque operation without hardware interruption or thermal shutdown
- IP 42-rated housing (per DIN EN 60529) combining cast aluminum structural integrity with thermoplastic polymer impact resistance and chemical splash resilience
- Low-noise mechanical design optimized for shared laboratory environments—acoustic emissions compliant with IEC 60704-1 for lab-grade equipment
- Error code diagnostics displayed directly on the LED panel, supporting rapid fault identification and operational continuity
Sample Compatibility & Compliance
The EUROSTAR 20 accommodates standard laboratory vessels from 50 mL beakers to 20 L stainless steel or glass reactors via its interchangeable clamping system and 16 mm extension arm (220 mm length). It interfaces seamlessly with IKA’s full portfolio of impellers—including propeller, anchor, paddle, and turbine types—as well as third-party ISO-standard stirring shafts. The unit complies with CE marking requirements, RoHS Directive 2011/65/EU, and electromagnetic compatibility standards IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emission). Its electrical safety conforms to IEC 61010-1 for laboratory equipment, supporting integration into GLP-compliant workflows where traceability and instrument qualification are mandated.
Software & Data Management
While the EUROSTAR 20 operates as a standalone digital stirrer without embedded PC connectivity, its analog-compatible 0–10 V control input enables integration into centralized process monitoring systems using external PLCs or data acquisition modules. All operational parameters—including setpoint, actual speed, error status, and runtime—are accessible via front-panel display and retained through power cycling. For laboratories requiring audit-ready records, optional IKA Labworldsoft™ software (via RS232 adapter) provides time-stamped logging, user-access control, and exportable CSV reports—supporting FDA 21 CFR Part 11 readiness when deployed with appropriate system validation protocols.
Applications
- Routine homogenization of aqueous and non-aqueous solutions in pharmaceutical formulation development
- Dispersion of nanomaterials and pigments in R&D-scale colloid synthesis
- Controlled agitation during titration, dissolution testing, and buffer preparation
- Mixing of high-viscosity adhesives, sealants, and composite precursors in materials science labs
- Stirring under inert atmosphere in glovebox-integrated reaction setups (compatible with optional gas-tight mounting kits)
- Accelerated aging studies requiring extended-duration constant-speed agitation at elevated temperatures
FAQ
Is the EUROSTAR 20 suitable for use in explosion-proof environments?
No—the unit is not certified for ATEX or IECEx hazardous area classification. It must be operated in general-purpose laboratory spaces meeting standard electrical safety codes.
Can the stirrer be mounted vertically on a fume hood sash?
Yes—its compact footprint (86 × 325 × 208 mm) and integrated clamp system support secure vertical or horizontal mounting on standard lab frames, fume hood rails, or modular support columns.
Does the device support external speed programming via analog signal?
Yes—via the 0–10 V input port, enabling synchronization with temperature controllers, pH meters, or automated reactor platforms.
What is the recommended calibration interval for speed accuracy verification?
IKA recommends annual verification using a traceable optical tachometer; no internal recalibration is required due to the sensorless brushless motor architecture.
Is firmware upgrade capability available?
Firmware updates are performed exclusively by authorized IKA service centers using proprietary diagnostic tools—no end-user flash functionality is provided.
