The Philips CM12 was a general purpose analytical transmission/scanning transmission electron microscope (TEM/STEM). It was used to visualize the structure, chemical composition, and arrangement of atoms in thin, extraordinary small specimens. This microscope was installed in 1989 and has been used for 21 years. The microscope was funded by The M. J. Murdock Charitable Trust and the OSU Research Office. The microscope was sold in 2012 to Semion, a small company in Hillsboro Oregon.
