FEATURES AND BENEFITS
Research-level Rosand RH7 and RH10 capillary rheometers provide highly flexible measurement capabilities for materials under high pressure and high shear rate extrusion - from polymer melts to ceramics, and from foodstuffs to inks and coatings.
High force range (up to 100kN) and wide dynamic speed range (up to 400,000:1) allow test correlation with real material processing conditions.
