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.
