The subject of the invention is a container for storing dehydrated biological material under a controlled atmosphere, especially at ambient temperature, and more particularly for storing DNA, comprising an envelope (12) made from a material that is impermeable to gases, characterized in that the envelope (12) is made from a metallic material and is of cylindrical shape sealed at one end and comprises a stopper (16) joined in an impermeable manner to by welding to said envelope at peripheral edges. The envelope and stopper and each monolithic and come from mechanical deformation by drawing.
