NEW DEVELOPMENTS IN THE
LABORATORY FOR EXPERIMENTAL RHEOLOGY
AT THE UNIVERSITY OF MASSACHUSETTS AT AMHERST

We are building a micro rheometer for very, very small samples


The rheometer has evolved from the shearing device of Müller et al. (1996), see paper by Müller JA, Stein RS, Winter HH (1996) Rotation of liquid crystalline macromolecules in shear flow and shear induced periodic orientation patterns. Rheologica Acta 35:160-167



This is our new high pressure rheometer/mixer for work with polymers in supercritical solvents. The rotating mixing element in the center will be enclosed by the housing (on right) and closed with a lid (bottom left). The sample will circulate through a high pressure view cell (left) for light scattering measurements.
