Various embodiments are generally directed to fluid container adapters that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. Several embodiments are particularly directed to a fluid container adapter that punctures a fluid container to couple with and gain access to the contents of the fluid container. In one embodiment, for example, a platform may be used to support a fluid container as one or more penetration members attached to a crossmember are advanced into the fluid container along rails connected between the platform and the crossmember. In such embodiments, the one or more penetration members may include lumens to enable a tubing set to access the contents of the fluid container.
