<p>The present invention concerns a cover (11) for cell culturing vessels and a cell culturing vessel. The cover (11) or the vessel may transit between three positions: sealed (A) for transport purposes, open (C) for extracting or adding to the contents of the cell-culturing vessel; and a vented position (B) which allows communicating of the contents of the vessel with ambient air, for culturing or sterilization purposes, but eliminates contamination caused by gravitation fall of particles from above. The cover of cell-culturing vessels of the invention or the cell-culturing vessel itself may transit between the three positions by a single-handed manipulation.</p> |
