Viscometer

During membrane formation the dope viscosity is a very important parameter. Therefore when spinning hollow fibers the dope viscosity is one of the important quality parameters. The Thermo Scientific HAAKE Viscotester® 550 measures the viscosity of a solution as function of shear stress (τ) shear rate (ϒ) and temperature. The measurement principle is based on the torque required to turn an object in a fluid.
