Abstract
The present invention concerns a device for the transfer and in-situ reactions under a controlled atmosphere, of specimens for transmissive electron microscopy, characterized in that it is additionally provided with a means (7) for guiding and locking in transport and analysis positions of the rod (1) provided with the grid holders (2), the said rod (1) being advantageously integrated by screwing with the corresponding end of the traction bar (5) which is guided in the cover (3), of which the opening (9) of the front part (3') of lesser diameter is extended over a portion of the length of this front part (3'), on both sides, by longitudinal grooves (10), the said front part (3') being connected to the rest of the cover (3) by screwing of a shouldered portion (11), a gasket (13') effecting the sealing at the level of the screwed assembly.
