Abstract: The invention relates to containers for the drying, especially the freeze-drying, of material. In particular, the invention relates to a lid of a drying container, said lid enabling to close the container body of the drying container so as to avoid i) contamination of the material to be dried inside the container and ii) spills of airborne solid particles of said material from the container to the environment. The lid comprises a lower and an upper frame with a vapor permeable sheet positioned in between. The invention further provides methods for the drying, especially the freeze-drying, of material.
