Steatite ampules are cylindrical enclosures designed by the Engineers to establish and maintain the controlled environment necessary to store A0-3959x.91 – 15 due to its unstable nature at ambient temperature. The exterior surface of the ampules are engraved with an information placard.
Within the ampules contain four conical-shaped glass phials that contain A0-3959x.91 – 15. This method was used to ensure A0-3959x.91 – 15's ability to retain infectivity and virulence after a prolong period of storage. All ampules are aligned in rows, kept at a distance of 0.9652 meters apart from one another due to the fact that errors in the ampules' temperature stability seems to be amplified with an increase or decrease in this distance.
