Rheometer AR 2000 (TA Instruments)
This state-of-the-art rheometer is a highly versatile instrument, capable of operating in many control modes: flow, oscillation, creep, stress relaxation, etc. as well as recent developed operation modes like parallel superposition and multi-wave testing. Being basically a controlled-stress rheometer, the super- fast Mobius drive makes the AR 2000 perfectly suitable for performing strain-controlled experiments. Due to the air bearing, the low inertia drag cup motor and rotational mapping, the instrument has a high sensitivity and is capable of detecting tiny differences in viscosity.
(Viscosity range: from 5 mPa.s to 104 Pa.s ) The Peltier temperature control allows very fast heating and cooling rates in the temperature range from -15°C up to 200°C. Cone/plate, plate/plate geometries and double gap peltier cylinder system are available.
