Claim Text:
1. A process for producing culture sample containers, comprising: introducing a colorimetric sensor material into a molded container body of a single monolithic layer of polymeric material, the container body having a container shape with a bottom and an upwardly extending wall; introducing growth media into the container body; introducing a gas or gas mixture into the container body under vacuum to define a headspace gas in an upper portion of the container body; attaching a stopper to the container body with the sensor material; sealing the container body with the stopper with the growth media and the headspace gas enclosed therein to form a sealed culture sample container; then sterilizing the sealed container; then applying a fluid gas barrier material to an exterior of the sterilized sealed container body to form a gas barrier coating as an exterior surface of the sealed culture container so that the sealed container has an oxygen transmission rate (cubic centimeter/container/day/atm air) that is between 0.00001 and 0.1; and providing the sealed container with the applied gas barrier coating as the exterior surface as a ready to use sealed culture sample container that is shelf stable and does not undergo post-gas barrier coating autoclaving.
