The Oxford Diffraction Gemini single crystal diffractometer with the CCD detector is available for sample screening, structure analysis as well as other crystallographic experiments with the resolution up to 0.35 A. There are possibilities to investigate crystals at wide temperature range of 15 - 800 K or in Diamond Anvill Cells (DAC) at pressure up to 50 GPa. Mo and Cu radiations give a possibilities to use the diffractometer with all single crystals.
