MCR 702
Rotational rheometer
the MCR 702 rheometer (Anton Paar) shows a higher torque sensitivity than the MCR 301. Additionally it can be driven with one or two motors. With two motors a decoupling of driving the geometry and the measurement of the torque can be achived. Furthermore, counter-rotating of the upper and lower geometry parts leads to a doubled maximum shear rate.
