RHEOMETRIC ARES RHEOMETER (1996)

Controlled strain for both oscillatory and steady shear measurements in parallel plate and cone-and-plate geometries. Used primarily for high viscosity liquids (such as polymer melts), with viscosities exceeding 10 Poise, between -100 oC and 400 oC under nitrogen.

The lower plate is driven by a motor, in either steady rotation or oscillation, while the upper plate is connected to a transducer, which measures torque and normal force. This rheometer is used to study entanglements in polymer melts and solutions, gels and branched polymers, miscible polymer blends, and structured fluids.
