Rosand Capillary Rheometer

The NETZSCH Rosand capillary rheometer is a powerful platform for measuring the flow behavior of polymers and highly viscous materials under real processing conditions. Designed to simulate industrial manufacturing environments, Rosand provides accurate rheological data at high shear rates, pressures, and temperatures relevant to extrusion, injection molding, compounding, and additive manufacturing.

Rosand enables characterization of shear viscosity, extensional viscosity, melt strength, die swell, and processing stability, helping researchers and manufacturers optimize formulations, improve processability, and predict material performance during production. The system supports a wide range of capillary dies, piston configurations, and advanced accessories for comprehensive polymer melt analysis.

With local support from Prisma Scientific, customers benefit from application expertise, method development assistance, operator training, and ongoing technical service for demanding rheological applications.
