ABSTRACT:
This culture dish comprises an axisymmetric receptacle (1) having a bottom on which is disposed a layer (2) of a culture medium and a movable lid (5), covering the receptacle (1) and having an internal face from which emerges a spreader (9), and structures associated with the receptacle and lid making it possible to transfer the lid (5) from a depositing position in which the spreader (9) is distant from the layer (2) to a spreading position in which it touches the layer (2), and which the structures are arranged such that the transfer requires two movements, in different directions, with respect to the receptacle (1), to be imparted to the lid (5).
