Abstract
Apparatuses for evaluating the integrity of a container seal and methods of using same are provided. The apparatuses include a sealed container having a conductive fluid and a first probe therein, a conductive solution bath having a second probe therein, a conductivity meter and a pressurized fluid supply. A pressurized fluid is supplied from fluid supply to an interior of the sealed container through the first probe until the seal on sealed container ruptures, first and second probes create an electrical circuit, and the conductivity meter detects a flow of electrons between the two probes. In this manner, apparatuses of the present disclosure are able to quantify the amount of internal pressure in the container at the time the container seal ruptures.
