TA Instruments DHR3 Rheometer

Bard Hall B56

The DHR3 can be used to measure: viscosity, shear stress, storage and loss modulus, strain, and phase angle – with respect to: time, temperature, shear rate and frequency.  It can also be used for transient testing such as creep and stress relaxation, and UV cure kinetics.  Available geometries include: 40 mm parallel plate, 25 and 40 mm 2° cones, and cup and rotor with options of vaned or conical rotor. It has three heating system options, Peltier plate, Peltier concentric cylinders, and an environmental test chamber.

Rheometer use during COVD19: 

Physically distanced training is now available for the DHR3 rheometer in combined forms including video training, remote live session and a brief in person session.  Researchers who are interested in training on the DHR3 Rheometer can begin by watching the Rheometer training video.  The video can be viewed as many times as needed and it is expected that the researcher will be able to answer questions pertaining to the material presented in the video.  Once users feel that they understand the material in the training video they can contact the instrument manager for next steps.
