Crystallographic Facilities at Otterbein University

The Department of Chemistry at Otterbein University has extensive equipment for the study of materials by X-ray diffraction, including both single-crystal and powder diffraction instrumentation.


External Users: How do I prepare and submit a sample for analysis? See the Sample preparation and submission page for information about how to arrange to have your sample analyzed.


Remote Access: See the SMART X2S Remote Access Info page for information about how to set up remote access, run an experiment, and process the resulting data.


Bruker SMART X2S Benchtop Single-Crystal X-ray Diffraction

Bruker SMART X2S Benchtop Single-Crystal X-ray Diffraction

The Bruker SMART X2S was purchased as part of an NSF-supported grant project (CCLI #0942850) to incorporate experimental structural chemistry into the undergraduate curriculum. The instrument has been used in General Chemistry, Inorganic Chemistry, and also to support undergraduate research. Some example structures are posted in the Structure Gallery. A video demonstrating the SMART X2S is below.

Oxford Cryosystems Desktop Cooler

 

 

Oxford Cryosystems Desktop Cooler

The Oxford Cryosystems Desktop Cooler (DTC) allows us to easily collect diffraction data down to 170K with no need for cryogens. We have used this feature to study the solid-solid phase transition in certain metal halide cluster salts (see Johnston, D.H.; Brown, C. M.; Yu, A. S.; Gallucci, J. C. Acta Cryst. 2010, C66, m303-306).

 

 

Zethus Software CyberLab

 

Zethus Software CyberLab Remote Access

The remote access and storage capabilities of the Zethus CyberLab system allow users to remotely control experiments, view resulting structures, and download reports and/or full data sets. It also provides automatic storage of all generated datasets.

 

Rigaku Miniflex II Powder Diffraction System

 

Rigaku Miniflex II Powder Diffraction System

The Rigaku Miniflex provides an additional tool for the characterization of organic and inorganic materials. We have used this instrument in our General Chemistry laboratory (characterization of sol-gel embedded gold nanoparticles), Inorganic Chemistry laboratory (synthesis of a superconductor) and for undergraduate research.




Demonstration of the Bruker SMART X2S (YouTube)

Note - the best part is right around 2:10, when it shows how the sample is automatically mounted and aligned on the goniometer.
