Bruker D8 Venture Duo X-ray Diffractometer

Bambu Lab X1E 3D Printer

The first is the Bruker D8 Venture Duo single-crystal diffractometer equipped with a Photon III detector, both Mo and Cu microfocus X-ray tubes, and an Oxford Cryostream 800 series N2 gas-stream sample cooler/heater. This instrument is ideal for determining the solid-state structure of new organic molecules, cocrystals, polyoxometalate clusters, or any other material that forms well-ordered single-crystal material with a minimum dimension of 10 µm. While most structures are determined using the instrument’s Mo source, having access to the Cu source on the instrument allows for the determination of the absolute configuration of chiral molecules without the need to synthetically add heavy atoms to your molecule.

The MATFab facility also hosts the Cambridge Database and associated software from the CCDC, which allows for quick determination of known structures and access to structures with similar molecular structures or intermolecular interactions.
