Small-molecule single-crystal X-ray diffractometer using an HFMR-007 rotating-anode generator to produce copper Kα radiation. The diffractometer is equipped with an Osmic Varimax HF ArcSec monochromator and XtaLAB P200 HPAD detector. An Oxford Cryosystems Cobra cryocooler enables data-collection between 80 and 500 K, with data routinely collected at 125 K.
