Abstract: An apparatus comprising a culture dish and a removable lid, wherein the culture dish comprises a main body having a side wall defining a reservoir region for receiving a quantity of liquid media, and the removable lid is arranged to cover the reservoir region during normal use, wherein the lid comprises a gas permeable material and includes an engagement portion formed of a resilient material adapted to cooperatively engage with the side wall of the main body of the culture dish so as to compress a part of the engagement portion of the removable lid against the side wall to form a vapour-tight seal for the reservoir region when the removable lid is coupled to the culture dish. The lid fitted to the culture dish enables a substantial portion of the culturing media to remain in the environment enclosed between the reservoir and the lid without use of a cover media to limit evaporation while allowing gaseous exchange therethrough.
