SR20 & SR50 Capillary Rheometers

The Instron® capillary rheometer systems of the SmartRHEO Series are specifically designed for R&D and advanced quality control of thermoplastic materials, accurately determining the rheological properties of polymer samples over a wide range of shear rates and testing conditions.

The SmartRHEO Series is a popular product line for capillary rheometry, meeting market demand for compact, stiff, reliable, and technically advanced instruments in the testing field.

The capillary rheometer systems are available in either single or twin-bore barrel configurations. The twin-bore configuration allows two simultaneous, independent rheological tests, with direct comparison of the behavior of two different samples or two lots of the same material. With a wide range of available accessories, testing capabilities expand to include the determination of fundamental properties like melt strength, die swell, and PVT (pressure-volume-temperature) behavior, allowing users to simulate processes such as injection molding, extrusion, blow molding, and film blowing.
