  • Device for preparing thin specimens
    Patent number: 4513537
    Abstract: A mechanical grinding device is provided for preparing very thin specimens such as transmission electron microscopy specimens. The specimens are held on the end of a long rod which is pressed against a spherical tool by the weight of the rod. The opposite end of the rod extends through a hole in a pivot plate which is spaced above the tool. The tool is mounted on a tool holder which is eccentrically positioned on a rotating base by a pivot. As the base rotates, the tool holder moves and a concave surface is ground in the specimen, thus thinning it.
