The lab-scale RheoSAXS system is the combination of two world-class Anton Paar instruments: The renowned SAXSpoint 700 delivers brilliant results on the nanoscale. Combined with the DSR 502 dynamic shear rheometer (based on the MCR rheometers) this makes RheoSAXS a unique setup for studying structural and rheological properties simultaneously in your lab. RheoSAXS resolves the combined information of samples within minutes.

Key features

Unlock new possibilities in RheoSAXS measurements

The RheoSAXS system combines precise rheological control with advanced X-ray scattering capabilities, delivering unmatched performance for complex fluid characterization. With a minimum torque of 10 nNm in rotation and 2 nNm in oscillation, it enables accurate measurements even for low-viscosity, dilute suspensions. The instrument is easy to handle thanks to the quick-coupling mechanism of the upper geometry, allowing fast, reliable setup changes. Clear alignment marks on the flange between the DSR 502 and the X-ray measuring chamber make switching from axial to tangential configurations effortless, ensuring seamless integration of rheology and SAXS analysis in one versatile system.

X-ray-transparent RheoSAXS measuring cell

The RheoSAXS setup enables simultaneous rheological and structural analysis by allowing measurements parallel or perpendicular to the flow direction. This makes it possible to precisely determine the orientation of the sample distribution relative to flow, offering valuable insight into flow-induced structural changes. The system features a cylindrical measuring geometry in accordance with DIN 53019, with a 1 mm gap and components made from X-ray-transparent polycarbonate, ensuring accurate and interference-free data acquisition. With a filling volume of 8 mL and precise temperature control from -10 °C to +90 °C, the RheoSAXS solution provides the ideal environment for consistent, reproducible measurements under realistic process conditions.

Seamless integratation into your SAXS analysis workflow

The RheoSAXS system integrates the DSR 502 measuring head directly into the SAXSpoint 700, ensuring perfect mechanical and optical alignment for simultaneous rheological and structural measurements. System setup and calibration are easily managed through the SAXSdrive™ software, enabling precise positioning and seamless operation. For comprehensive data evaluation, SAXSanalysis™ allows detailed interpretation of the scattering results, while RheoCompass™ provides advanced analysis of rheological parameters. Together, these software tools deliver a fully integrated workflow for correlating structural and rheological behavior in real time.
