IKA EUROSTAR 20 digital overhead mixer with LCD display, up to 25 litres, 0020105154

The IKA EUROSTAR 20 digital overhead stirrer (MPN 0020105154) represents the modernised, highly optimised mechatronic generation of universal laboratory stirrers for simple to moderately demanding mixing tasks. With a footprint reduced by up to 23 per cent compared to its predecessor models, this compact instrument fits perfectly into any flexible laboratory layout. Designed for sample volumes of up to 25 litres (based on water), the system handles viscosities of up to 10,000 mPas with ease. It thus offers the ideal process engineering system solution for routine applications, standard mixing processes and reproducible analytical runs in a professional B2B laboratory environment.

Innovative torque trend measurement for sample monitoring

An outstanding metrological feature of the digital series is the integrated torque trend measurement. The system records transient changes in the medium’s viscosity with an accuracy of ±6 Ncm and displays the relative viscosity trend directly on the clear LCD display. This provides laboratory staff with valuable insights into the current state of the mixing process at all times. Thanks to a sophisticated automatic speed adjustment system covering a wide range from 30 to 2000 revolutions per minute, the stirrer maintains the selected speed absolutely constant even during transient changes in viscosity, thereby ensuring error-free results.

Ergonomic tool change and high operational safety

From a process engineering perspective, the EUROSTAR 20 digital is consistently designed for maximum user-friendliness and process reliability in daily continuous operation. The integrated quick-release chuck allows the user to change stirring tools comfortably with one hand, without the need for any additional tools. A dedicated lock button protects the system during operation against accidental parameter changes by the user. To reliably prevent mechanical damage or hazardous situations, the stirring drive features autonomous safety circuits which trigger an immediate automatic shutdown in the event of an overload or blockage of the stirring element.

Future-proof connectivity and robust housing design

The system’s infrastructure architecture enables straightforward integration into digitised laboratory workstations. Equipped with standard USB-C and RS232 interfaces, the overhead stirrer can be seamlessly connected to a PC and fully controlled and comprehensively documented via the labworldsoft laboratory software ®. The mechanically robust housing consists of a combination of coated die-cast aluminium and sturdy thermoplastic, which meets the demanding IP 54 protection rating. The brushless DC motor operates virtually wear-free, whisper-quiet (52 dBA) and absolutely clean, meaning the system is fully qualified for a 100 per cent duty cycle in continuous operation.
