Reliable single-crystal diffractometer for molecules/proteins, low background, 137° 2θ.
STADIVARI
● Flexible goniometer (Eulerian cradle and various fixed chi setups)
● Sphere of confusion of less than 0.005 mm radius
● Ultrafast hybrid pixel detector (full EIGER and PILATUS detector range)
Being conceptualized to offer a wide scope of applications, the STOE STADIVARI can be set up vertically as well as horizontally. It can be used for single crystal as well as powder diffraction, with the open Eulerian cradle offering enough space for high pressure cells, high- or low-temperature devices or other accessories.
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.
Moreover, the STADIVARI is fully integrated in the well-established STOE X-AREA software package.
