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

Not every viscosity test should be carried out separately from the stirring process. When mixing dispersions, paints or adhesives, it is often more practical to monitor the viscosity directly whilst stirring, rather than taking a sample and measuring it separately. The STARVISC 200-2.5 control is an overhead stirrer with integrated torque and viscosity measurement; not a stand-alone precision rotational viscometer like the ROTAVISC series, but a stirrer that provides viscosity as a process parameter.

Mixing and viscosity in a single step

During the mixing and production process, the device calculates and displays the viscosity directly on the screen, without the need to take a separate sample. This is particularly useful in product development when, during ongoing test series, it is necessary to check whether a mixed substance has reached the desired consistency. The maximum measurable viscosity value is 100,000 mPas.

Power and torque for viscous fluids

The brushless DC motor draws 130 W and delivers 84 W to the stirring shaft, with a permissible duty cycle of 100 %. Two speed settings cater for different requirements: setting I delivers 6 to 400 rpm with a maximum torque of 200 Ncm, whilst setting II delivers 30 to 2,000 rpm with a maximum torque of 40 Ncm. The rated torque is 2 Nm; the mixing capacity for water is up to 100 litres per mixing point. The chuck accommodates tools ranging from 0.5 to 10 mm.

Detachable WiCo display for the remote control

The WiCo control display can be detached from the drive and transmits control commands back to the drive unit from a communication range of up to 150 m, depending on the building. Anyone wishing to monitor or control the stirring process from a safe distance, for example, during reactions where there is a risk of splashing, will benefit from this separation between the drive and the control unit. A PT-1000 sensor is provided for the temperature connection; the measuring range extends from -10 to +350 °C, with a resolution of 0.1 K.

Power supply and connections

A lithium-polymer battery (3.7 V, 7.4 Wh) is permanently fitted in the drive unit; the device is otherwise powered by 230 V. According to IKA, other voltage options are available. An RS-232 port and a micro-USB interface are provided for connection to laboratory software; the housing is made of coated cast aluminium and thermoplastic.

Typical applications

The device is suitable for use wherever viscosity is monitored in real time whilst stirring, rather than being measured separately afterwards.

• Product development with continuous viscosity monitoring during the mixing process
• Mixing dispersions, paints, adhesives and similar mixtures
• Remote control via the detachable WiCo display for operations requiring a greater safety distance
• Mixing tasks requiring high torque at low speed (Stage I)
• Temperature monitoring of the sample via the PT-1000 connection

Regulatory information

This device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG). The WEEE registration number of the manufacturer, IKA, is DE 66784213. Information on the return of old appliances can be found on our page Environment and disposal.

Warranty and procurement service

IKA manufacturer’s warranty: 2 years; extended to 3 years upon registration at ika.com/register within 90 days of purchase. For pure, precise viscosity measurement without the need for stirring, a rotational viscometer from the ROTAVISC range is an option, for example for samples that have already been mixed and simply need to be tested. On the other hand, if you need both stirring and viscosity measurement in a single step, the STARVISC is an option. Stirring elements, stands and other IKA accessories for overhead stirrers can be viewed in our viscometer section. For bespoke combinations of stirring tools, stands and temperature probes, we advise you through our procurement service.
