Apparatus and method for storing gas samples |
摘要 |
A vial for the storage of soil gas samples comprises a chamber having a passage extending away therefrom which serially defines a generally annular shoulder and a generally frustoconical surface each facing away from the chamber. A resiliently pierceable septum is positioned against the shoulder and a shaped plug is positioned against the generally frustoconical surface to provide a redundant seal.
