A port and closure device for a vessel that is configured for use with a glove bag. The port comprising includes a first annular flange with an opening, a second annular flange disposed a predetermined distance from the first flange and also having an opening, and a seal ring disposed adjacent the first annular flange and having an additional opening. At least a portion of the openings are aligned so that a path is provided through the flanges and the seal ring. A slideable door is included in the port between the seal ring and the second annular flange. The slideable door has a first position that obstructs the path and a second position that is outside of the path. Springs are disposed between the first flange and the seal ring that urge the seal ring toward the slideable door. To reduce contamination sites, the springs may be sealed within an annular interface between the first annular flange and the seal ring. Alternatively, or in addition, a funnel pipe may be used with the port disposed in the openings of the first and second flange and the seal ring. The port may also include an adapter configured to hold a glove bag thereon.
