The fastest and most flexible way to explore reciprocal space

With the possibility to be set-up vertically as well as horizontally, the STADIVARI increases its scope of application. The STADIVARI can be used for single crystal and powder diffraction. The Open Eulerian Cradle offers enough space to add high pressure cells, high- or low- temperature devices or other chambers.

Product Description

In the dual beam setup, all combinations of tubes and microfocus BDS are possible: two sealed tubes, one sealed tube and one microfocus BDS or two microfocus BDS.

As the youngest member of the long line of STOE diffractometers, the STADIVARI is fully integrated in the well-established STOE X-Area software package.


  • Flexible goniometer (Eulerian cradle and various fixed chi setups)
  • Sphere of confusion < 0.01mm
  • State of the art interface
  • Various sources (Microfocus BDS etc.)
  • Ultrafast hybrid pixel detector
