ABSTRACT:
The invention concerns an apparatus for preparing monolayers of cells. The apparatus comprises a container (6) for a cryosubstitution system and an insert (1) for the container, the insert (1) having a surface (1a) and a plurality of orifices (3). An SCS (2) together with a cellular monolayer (20) is insertable into each of the orifices (3). The SCS (2) is thus arranged perpendicular to the surface (1a) of the insert (1).
