Abstract

Apparatus for the cryofixation of specimens, comprises a tank adapted to contain a cold gaseous medium having an upper boundary with an atmosphere external to the tank, and cooling means having an upper surface, said cooling means being disposed within the tank. The upper surface is movable between a lower level and an upper level which is below the upper boundary. The upper surface is maintained at the upper level for a period sufficient to permit the application of a specimen to the upper surface, and is then lowered to the lower level.
