IKA EUROSTAR 60 control Advanced Digital Overhead Stirrer

Overview

The IKA EUROSTAR 60 control is a high-precision, microprocessor-driven overhead stirrer engineered for reproducible mixing, dispersion, and homogenization tasks in research laboratories, quality control environments, and pilot-scale development workflows. Based on brushless DC motor technology, it delivers stable torque output and closed-loop speed regulation—continuously comparing actual shaft speed against setpoint and dynamically compensating for load-induced deviations. This ensures consistent rotational energy delivery even during viscosity transitions (e.g., polymer dissolution, emulsion formation, or thermal gelation), making it suitable for kinetic studies where shear history must remain controlled. Its robust cast aluminum and thermoplastic housing provides mechanical stability while meeting IP40 ingress protection for typical laboratory environments. Designed and manufactured in Staufen, Germany, the unit complies with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards, and conforms to EN 61010-1 for electrical safety in laboratory equipment.

Key Features

• Brushless DC motor architecture enabling maintenance-free operation, extended service life, and low acoustic emission (<55 dB(A) at 1 m)
• Closed-loop speed control with real-time deviation correction—maintains set speed within ±1 rpm (n > 300 rpm) despite changing medium viscosity or density
• Integrated torque trend monitoring function for indirect viscometric profiling; displays dynamic torque response over time on the TFT screen
• Programmable timer (1–6000 min) with intermittent stirring mode and automatic shutdown
• PT1000-compatible temperature input (–10 to +350 °C) with Class A accuracy per DIN IEC 751; supports external probe integration for reaction temperature correlation
• Wireless WH 11 controller with 150 m operational range (line-of-sight), enabling remote parameter adjustment and status monitoring without physical access to the unit
• Hollow shaft design (11 mm inner diameter) permitting insertion of temperature probes, pH electrodes, or sampling needles during operation
• Overload protection circuitry with automatic motor shutdown upon stall or excessive torque demand (>60 N·cm)
• RS232 and USB interfaces supporting bidirectional communication with PC-based lab software for method storage, parameter logging, and GLP-compliant audit trails

Sample Compatibility & Compliance

The EUROSTAR 60 control accommodates a broad range of sample types—from low-viscosity aqueous solutions to highly structured non-Newtonian systems (up to 50,000 mPa·s). Its universal chuck (0.5–10 mm clamping range) accepts standard glass, PTFE-coated, or stainless-steel impellers—including propeller, anchor, paddle, and turbine geometries. The unit is certified to EN 61010-1:2010+A1:2013 for safety in laboratory use and meets electromagnetic compatibility requirements per EN 61326-1:2013. While not intrinsically safe or explosion-proof, its design excludes ignition sources and complies with cleanroom-compatible material specifications (non-shedding thermoplastic surfaces, anodized aluminum housing). It supports method validation under ISO/IEC 17025 and aligns with GMP-relevant documentation practices when used with compliant data acquisition software.

Software & Data Management

Via RS232 or USB, the EUROSTAR 60 control integrates with IKA Labworldsoft™ (v5.0+) or third-party SCADA/HMI platforms supporting ASCII protocol commands. All operational parameters—including speed, torque, temperature, elapsed time, and error codes—are timestamped and exportable in CSV or XML format. Audit trail functionality records user logins, parameter changes, and system events—meeting FDA 21 CFR Part 11 requirements when deployed with appropriate electronic signature and access control configurations. Firmware updates are performed via USB stick, ensuring long-term adaptability to evolving regulatory expectations and laboratory informatics infrastructure.

Applications

• Kinetic studies of polymerization, crosslinking, or crystallization requiring constant shear rate under variable viscosity conditions
• Preparation of stable suspensions, colloids, and nanoemulsions in pharmaceutical formulation development
• Controlled dissolution testing per USP and Ph. Eur. 2.9.3, especially when coupled with inline temperature and turbidity monitoring
• Bioreactor seed train mixing and buffer blending in upstream bioprocessing
• Standardized ASTM D2196 or ISO 2557-2 viscosity screening using defined impeller geometry and rotational profiles
• Material compatibility testing of coatings, adhesives, and sealants under thermal ramping protocols

FAQ

Does the EUROSTAR 60 control support continuous duty operation?
Yes—it is rated for 100% duty cycle under specified ambient conditions (5–40 °C, ≤80% RH) and load limits (≤60 N·cm torque, ≤50,000 mPa·s viscosity).
Can external sensors other than PT1000 be connected?
No—the analog input is configured exclusively for PT1000 resistance thermometers conforming to DIN IEC 751 Class A tolerances.
Is firmware update capability available in the field?
Yes—updates are delivered via USB flash drive and require no service technician intervention.
What safety certifications does this unit hold?
It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and complies with EN 61010-1:2010+A1:2013 for laboratory electrical equipment safety.
How is data integrity ensured during PC communication?
All transmitted parameters include CRC checksums; Labworldsoft™ enforces role-based access control, electronic signatures, and immutable audit logs aligned with 21 CFR Part 11 Annex 11 principles.
