Function: Analytical/Synthesis

Department: CLAS Research Technical Services


The Electron Microscopy (EM) division of the CLAS Bioimaging Facility is supervised by Associate Professor Robert Roberson and laboratory manager David Lowry. The laboratory is located in a purpose-designed suite in the sub-basement of the Life Sciences C-wing building. The entire lab area of more than 1400 square feet has a vibration-isolation floor, which is critical for EM analysis. Interior space consists of 5 rooms containing microscopes and ultramicrotomes, a preparation lab with fume hood for chemical procedures and sample processing, and a room which houses a specialized instrument designed for high-pressure freezing of samples at liquid nitrogen temperatures. In addition to the life sciences community, the lab provides services to both on-campus and off-campus researchers from various disciplines that may require EM. Please refer to our Resources below for a detailed list of microscopes and associated instruments currently available for use in the lab. The EM Facility is part of the CLAS Bioimaging Facility.
