IKA STARVISC 200-2.5 control measuring stirrer, viscosity measurement, 200 Ncm, 0025003604

More than just stirring: the IKA STARVISC 200-2.5 control measuring stirrer

The IKA STARVISC 200-2.5 control (MPN 0025003604) defines a new class of laboratory equipment: the measuring stirrer. Whilst conventional overhead stirrers are primarily used to homogenise liquids, the STARVISC also functions as an intelligent analytical instrument. It enables the viscosity of the medium to be monitored and recorded during the stirring process. This makes it an indispensable tool in process development, polymer research and the scaling up of formulations where structural changes in the sample (e.g. curing, gelation) need to be detected in real time.

Precise torque measurement for viscosity trends

At the heart of the STARVISC is its high-precision torque measurement. The instrument measures the resistance exerted by the sample against the stirring tool with the utmost accuracy. What does this mean for your application?

• Real-time viscosity: The display shows not only the torque (in Ncm) but also the calculated viscosity.
• Process monitoring: You can track live how the viscosity changes during a reaction – for example, during polymerisation or whilst an emulsion is cooling.
• Trend display: The modern TFT display visualises the progression of the measured values graphically, allowing you to identify critical points (e.g. the gel point) immediately.

Please note: The STARVISC is not a substitute for a high-precision rotational viscometer under defined conditions (ISO/DIN), but it is the perfect tool for relative viscosity measurements under real process conditions in a beaker or reactor.

Powerhouse for highly viscous media

With a maximum torque of 200 Ncm, the STARVISC 200-2.5 control is extremely powerful. It can handle stirring tasks that standard stirrers cannot manage.

• Volume: Up to 100 litres (H₂O) can be reliably mixed.
• Viscosity: Media up to 100,000 mPas (e.g. viscous pastes, bitumen, polymer melts) are processed powerfully and consistently. Even under extreme load fluctuations, the intelligent control system maintains the set speed (0/6 – 2,000 rpm) absolutely constant.

The IKA “control” concept: WiCo and connectivity

Like all top-of-the-range IKA agitators, the STARVISC also features the detachable WiCo (Wireless Controller) control unit.

• Safety: Operate the stirrer from a safe distance, e.g. when the unit is located in a fume cupboard or when working with hazardous vapours.
• Convenience: You can monitor all parameters (speed, torque, timer, temperature) on the handheld unit.
• Software connectivity: The STARVISC can be connected to the labworldsoft laboratory software ® via USB or RS 232. This allows you to run complex ramp profiles, document all data comprehensively and control automated test series.

Versatility in detail

• Temperature measurement: A connection for a PT 1000 temperature sensor is integrated. This allows you to correlate changes in viscosity directly with temperature.
• RESPONSE: You can set threshold values (e.g. ‘If torque > 150 Ncm, then reduce speed’). This protects your equipment and the sample from overload.
• Versatility: Thanks to the push-through stirring tool and the standard chuck, you can use almost any existing stirring instrument.

The IKA STARVISC 200-2.5 control is the ideal investment for researchers who want to gain a deeper insight into their processes. It eliminates the need for a separate sampling step for viscosity measurement and delivers data directly from the reactor.
