ABSTRACT:
A rheometer and method for determining rheological characteristics of a composition, the rheometer including: a housing member; a helical flange disposed on an inner surface of the housing member; a rotor disposed concentrically within the helical flange and abutting the helical flange while maintaining sliding contact with the flange, wherein the rotor and the helical flange form a helical channel; a mechanism for rotating the rotor; a mechanism for introducing a sample of the composition into one end of the channel; a mechanism for controlling removal of the sample from the other end of the channel; and a mechanism for measuring a pressure difference of the sample between an upstream location and a downstream location in the channel.
