ABSTRACT:
The invention relates to a transfer mechanism for transferring a specimen (2) from a first position in a first holder (40) to a second position in a second holder (10) and/or vice versa, each holder (10, 40) equipped to detachably hold the specimen, the transfer of the specimen between the holders taking place in a transfer position different from the second position, characterized in that when the specimen is transferred between the holders (10, 40) a mechanical guidance mechanism positions the holders with a mutual accuracy higher than the mutual accuracy in the second position, and said mechanical guidance mechanism not positioning at least one of the holders (10, 40) when the specimen is in the second position. The mechanical guidance mechanism may comprise extra parts (50). At least one of the holders (40) may be equipped to hold a multitude of specimens.
