A container for biological liquids such as a culture medium comprises a hollow body of elastomeric material including a tubular intermediate part, rounded ends and a portion perforable by a cannula for introducing the biological liquid and hermetically resealing itself once the cannula is removed. The interior and exterior surfaces of the hollow body are smooth and curved throughout and the portion perforable by the cannula is thick walled and is preferably provided at one or both ends of the hollow body. The container may comprise two half shells joined together or a blow extruded member. The interior surface is advantageously coated to eliminate asperities.
