The X-ray laboratory provides access to state-of-the-art single-crystal and powder X-ray diffraction facilities and offers professional crystallographic advice and services to the members of the Department of Chemistry as well as to external members of the scientific community. The laboratory actively participates in scientific research, crystallography education, and outreach activities.

The single-crystal laboratory is equipped to handle a broad array of organic and organometallic crystals, stable and unstable crystal, and crystals of exceedingly small size. The lab hosts two modern single-crystal X-ray diffractometers and two high-end microscopes.

The powder diffraction laboratory is home to a modern X-ray diffractometer operated by trained users. All trained users can book time on the powder diffractometer.

The laboratory is part of the Paul Bender Chemistry Instrument Center at the Department of Chemistry of the University of Wisconsin-Madison.

New single-crystal X-ray diffractomer

A new state-of-the art single-crystal X-ray diffractometer has become operational. The Bruker D8 VENTURE Photon III four-circle diffractometer with a Cu Kα (λ = 1.54178 Å) radiation source is ideally suited for studies of organic molecules as well as small crystals in a 100–400 K temperature range.
