| abstract |
An apparatus and a process for preparing a material, such as a sample, for analysis, observation, recording or the like, at a high accuracy, by a simple construction and simple operation, which can form a cut face and/or a cut rift while preventing deformation, destruction and denaturing of the material. The process involves embedding a part of the material (11) in a filler (13) in a holder (4) of a holding unit (1) under settling with a settling means (5), holding the protruding portion (11b) of the material (11) by a protruding portion support (7) of a mount (2), freezing the material (11) instantaneously by dry ice placed in dry ice wells (6a, 6b) while effecting a gas phase replacement and cutting the material (11) by a cutter (22) to form a cut face (14) and/or a cut rift (15). |
