A method of installing a flexible bioprocess container in a bioprocessing system having a rigid housing with an interior compartment and extending between a top and an opposing base. The method includes coupling a first surface of the flexible bioprocess container to a moveable platform positioned within the interior compartment of the rigid housing; coupling a second surface of the flexible bioprocess container to the base of the rigid housing; and moving the movable platform relative to the rigid housing and toward the top of the rigid housing so as to at least partially expand the flexible bioprocess container within the interior compartment of the rigid housing.
