Abstract
A container for culturing a test sample includes a molded monolithic single layer polymeric container body having an upwardly extending, visually transmissive wall with an inner surface and a wall thickness that is between about 0.2 mm and 10 mm. The container also has a thin gas barrier coating comprising silica on the inner surface of the sealed container body and an internal top coating on the gas barrier coating. The gas barrier and top coating are visually transmissive (after curing). The container includes a cap sealably attached to the container body. The sealed container has an oxygen transmission rate (OTR) after autoclaving and aging that is between about 0.0001 to about 0.04 (cc/package/day/atm).
