A hermetically sealed vial for liquids is provided by the present invention. The liquid can be a calibrant or a reference fluid for gas analysis where the liquid has dissolved gas or medication or medicaments. The vial is a glass container means with at least one opening. The dimensions of the opening range from that which is just effective for the addition and removal of fluids to that which is the smallest side of the container. A flange circumferentially extends about the opening. The vial has the liquid that does not fill the vial to leave room for a head space. The head space is present in an amount of the volume percent of the vial ranging from 1 to 99 compared to the amount of the liquid. The vial is sealed with an air impermeable bilaminate seal comprised of an adhesive polymer contacting the vial and a metal surface facing externally from the vial. Before the vial is sealed by heat or induction sealing a securing means like a cap or chemical coupling agents are used to hold the seal on the vial. When the cap is a snap cap a gasket can be present between the cap and the seal. The vials can be sterilized and processed as a plurality of vials during heat and induction sealing…
