<p>Plastics material-containing closed containers (e.g. elastomer-stoppered vials) for contrast agents and contrast agent precursors which incorporate or are adapted to incorporate a volatile substance (e.g. a gaseous halocarbon such as a perfluorocarbon), where the plastics material is pretreated by exposure to the volatile substance. Such containers may enhance the storage stability of the contrast agent or precursor content.</p> |
