Apparatus and methods for applying a barrier to a medical scope are provided. An apparatus may comprise a source of film and a housing. The housing may comprise a chamber configured to support therein the source of film, and an opening provided through a wall of the housing to permit a portion of the film to extend out of the chamber when the film is dispensed. The housing may comprise a recess located such that the extended portion of the film is permitted to hang freely in proximity to the recess. The recess may be sized to receive a distal portion of the medical scope. The recess may be adapted to allow the extended portion of the film to be applied to the distal portion of the medical scope when the distal portion is placed into the recess with the portion of the film located therebetween.
