Abstract: A fluid container has a container body defining an interior volume, a port providing access to the interior volume, and a dry break attached to the port for forming a dry break coupling with a second device. The fluid container can be part of a closed fluid transfer system that includes the fluid container and a closed system transfer device. The dry break on the fluid container defines a first passage in fluid communication with the port. A first septum seals the first passage. The closed system transfer device has a housing configured to receive at least a portion of the dry break. A carrier is movable in the housing. The carrier defines a second passage and includes a second septum that seals the second passage. A cannula is at least partially disposed in the second passage.
