  • Carrier arm seal for a microtome of ultramicrotome
    Patent number: 5299481
    Abstract: A microtome, or an ultramicrotome having the specimen arm operating through an opening in the cryo chamber wall in a manner substantially free of the mechanical influence of a conventional seal is disclosed. An elongated slot permits movement of the specimen arm while minimizing the clearance between the sides of the arm and chamber wall reduces loss. Inner and outer baffles can be used to further reduce loss.
