  • Single tilt rotation cryotransfer holder for electron microscopes
    Patent number: 6410925
    Abstract: A cryotransfer holder for side entry transmission electron microscopes is provided. The cryotransfer holder design permits a specimen to be rotated about its axis as well as tilted while being maintained at a low temperature. The holder allows two sets of tilt data, preferably perpendicular to one another, to be collected from a single frozen specimen.

  • Double tilt and rotate specimen holder for a transmission electron microscope
    Patent number: 6388262
    Abstract: A side-entry specimen holder for transmission electron microscopy is provided. The specimen holder is capable of rotating a specimen and tilting it in two axes. The specimen, when mounted in the holder, can be tilted in the plus/minus direction of the X-axis, the plus/minus direction of the Y-axis, and simultaneously have the ability of 360° rotation in the axis of the electron beam to permit alignment of microstructural features of the specimen for optimal viewing and analysis.
