ABSTRACT:
A sterile housing for the cultivation of micro-organisms has a container closed by a cover with a culture medium within the walls and base. The cover has a bottom forming a base and walls connected to the bottom, and the lid is set on the container and includes a peripheral sealing zone having a flat section recessed relative to the bottom of the container. A concave inner seal is fixed to the peripheral sealing zone of the lid to hermetically seal the box by enclosing the container, enabling the inner seal to be removed without exposing the culture medium.
