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.
