Short Description: Image plate diffractometer equipped with molybdenum sealed-tube source and focussing monochromator. Allows collection of low- and high-angle data in a single setting. Very high contrast. Allows very fast routine structure determination. Ideally suited for electron density studies.		Picture of the Equipment $Small Molecule X-Ray Diffraction II$
Available Experiments/Techniques: Single crystal X-Ray diffraction (routine) Single crystal X-Ray diffraction (high angle&charge density)
Special Equipment: Equipped with an Oxford Cryostream 700 crystal cooling device (90 - 400K). Custom apparatus for low-temperature (-120°C to RT) crystal mounting under inert conditions is available. Binocular polarizing microscope with digital camera is available for crystal mounting/evaluation.
Measurements on the equipment are currently done by:		Students after extensive training Trained scientific service personal
