Oscillating rheometer. (Instrument).The RheoWave 1 OSC-Rheometer (RW1) is said to be an economically priced instrument for advanced rheometric characterization of fluids and melts. The RW1 is available in two torque ranges. The fluids version comes with two interchangeable in·ter·change·a·ble adj. That can be interchanged: interchangeable items of clothing; interchangeable automotive parts. in , low inertia inertia (ĭnûr`shə), in physics, the resistance of a body to any alteration in its state of motion, i.e., the resistance of a body at rest to being set in motion or of a body in motion to any change of speed or change in direction of , parallel plates which cover a wide range of thin fluids such as polymer solutions, stabilizers, thickeners, weak suspensions, emulsions, foams, etc. Zero shear viscosity can be determined with a creep recovery test. The melt version of the RW1 uses standard cones/plates and provides five times higher torque for testing medium to high viscosity materials. This version uses dynamic oscillation Oscillation Any effect that varies in a back-and-forth or reciprocating manner. Examples of oscillation include the variations of pressure in a sound wave and the fluctuations in a mathematical function whose value repeatedly alternates above and below some to get both viscosity and elasticity data. Creep tests can be performed to check for practical yield points or to get the low shear viscosity. Measurements at elevated temperatures up to 350 [degrees] C determine G', G" of polymer melts over a wide range of frequencies, according to according to prep. 1.
