Aalto University, School of Chemical Engineering, Department of Bioproducts and Biosystems is seeking a High-Pressure Capillary Rheometer that will be used to measure visco-elastic fluids under high shear stress and shear rate. The majority of samples will be non-Newtonian polymer melts and solutions or suspensions of one or several biopolymers. The equipment must allow the measurement at temperatures of at least up to 300 °C and at shear rates of up to 10^4 s^-1 for systems with a zero shear viscosity of 10^5 Pa.s.
A more detailed description of requirements is in the Annexes.
