The Physica MCR501 is a state-of-the-art controlled shear-rate (CSR) or controlled shear-stress (CSS) rheometer for offline rheology or in-situ Rheo-SANS measurements. Rotational speeds range from 10-6 to 3000 rpm, approximately corresponding to shear rates from <10-5 to 15000 s-1. In oscillatory mode frequencies between 10-5 and 100 Hz are possible. The maximum normal force is 50 N.

Offline the instrument may be used with parallel plate, cone-and-plate, or Couette measuring geometries, but Rheo-SANS experiments can only be performed with a special Searle-Couette (rotating stator) measuring geometry because of the relatively large diameter of the collimated neutron beam.

We have SANS Couette cells manufactured in synthetic quartz and Grade-V Titanium depending on the temperature requirements of the experiment.
