An apparatus and system for transferring a liquid, such as an anesthetic, from the outlet port of a reservoir to a machine while effectively and conveniently minimizing the release of anesthetic. In one embodiment, the apparatus and system can include a first valve movable between a first position and a second position; a first housing surrounding the first valve; a second valve slidably connected to the first valve and movable between a third position and a fourth position; and a second housing which surrounds the second valve; wherein the apparatus defines a first opening, a second opening, and a receiver passage between the first and second openings. In another embodiment, a movable plunger can be slidably connected to the second valve.
