An apparatus includes means for providing one-way degassing valves to be installed on corresponding containers; means for placing a viscous liquid in each of the plurality of one-way degassing valves to provide a corresponding plurality of installable one-way degassing valves; means for capturing an image of at least a portion of at least some of the plurality of installable one-way degassing valves; and control means for automatically and non-destructively determining for the at least some of the plurality of installable one-way degassing valves, prior to installation on the corresponding containers, by using the image, whether the viscous liquid has been properly placed.
