The RHEOGRAPH is a modular High-Pressure Capillary Rheometer in accordance with ISO 11443. It is used to determine the flow behavior and viscosity of thermoplastics and rubbers. This capillary rheometer is the result of more than 50 years of experience gained by GÖTTFERT with the previous model generations in the field of capillary rheometry. Besides viscosity measurements over an extremely broad range of shear rates, our capillary rheometer is the basic instrument for a wide range of Add-Ons for advanced polymer characterization, e. g.: Contifeed, thermal conductivity, PVT-measurements, counter pressure chamber, elongation measurements, die swell measurements and shark-skin measurements.
