Abstract
An automatic loading apparatus (12) for specimens (1) for high-pressure cryosubstitution is disclosed. The automatic loading apparatus (12) is connected to a high-pressure freezing device (40). Specimens (1) are inserted in a holder (2). By means of a slider (4), the specimens (1) and holders (2) are conveyed to the automatic loading apparatus (12). The guidance element (26) allows exact positioning of the holder (2) in the clamping element (14). The automatic loading apparatus makes possible rapid transfer of the holder (2) having the specimen (1) from, for example, an optical microscope to the high-pressure freezing device (40).
