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.

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 of less than 0.01 mm
  • Different source solutions (Standard sealed tubes, Microfocus, MetalJet or synchroton)
  • Ultrafast hybrid pixel detector
  • Various non-ambient attachments (high and low temperature, high pressure)

X-ray fibre optics

On STOE’s Imaging Plate Diffraction Systems IPDS II, IPDS 2T and the STADIVARI with the DECTRIS PILATUS detector the normal pin hole collimator can be exchanged against an X-ray fibre optic. The use of this optic provides a gain in intensity  depending on the anode material (eg. factor 2 for Mo Kα, better for Cu Kα), sample dimension (and sample-to-detector distance).

  • In this way the well known accuracy of the data sets can now be obtained in 1/2 of the exposure time with Mo radiation.
  • The data quality stays the same or is even better while no significant raise in the background is observed.
  • No broadening of peak halfwidths could be detected.

The X-ray fibre optic is an effective and inexpensive alternative to a rotating anode at the STOE Imaging Plate Diffraction System IPDS II, IPDS 2T and the STADIVARI with the DECTRIS PILATUS detector.

Goniometer heads

STOE provides the suitable goniometer head for each task, whether large, standard or small, lockable x,y,z or fully height adjustable, all STOE goniometer heads are of excellent precision, have the standard IUCR mount and are delivered with the necessary equipment.

Temperature attachments

Low Temperature
O.E.M. attachments like the Oxford Cryosystems coolers can easily be mounted on each STOE single crystal diffractometer. The low cost and low maintenance Desktop Cooler (DTC) can be used as well as the traditional Cryostream or the non-liquid nitrogen Cobra.

As non-ambient methods are becoming increasingly popular, STOE provides a powerful high-temperature attachment for its single crystal diffractometers, the HEATSTREAM.
– Temperature range from RT to 1000 K
– Temperature accuracy within +/- 1 K – Heating medium N2
– No limitation in 2Θ, ω or &phi
– Vertical gas flow for optimal sample heating
