Come see them in our open house on Tuesday, November 14th from 12:30 pm to 3:30 pm. Enjoy some finger food and a Moche. See a Moche in the environmental SEM!

RELMS , our scheduling system is in full swing and it has really helped streamline our billing. As of April 1st, RELMS was the platform that will be used for booking Quanta 600, Quanta 3D, Titan and Helios.

At this time masks are not required

And as always, we strive to treat all nationalities and ethnic backgrounds with respect and equity.


In addition to an FEI Titan with ChemiSTEM technology, we have staff that are experts in sample preparation and imaging to help you solve your problem. A walk through of the OSU Electron Microscope Facility is available by clicking on the links above.

The facility is supported from the Office of Vice-President for Research and the facility's client colleges. The facility is located in Suite 145 in Linus Pauling Science Center.
