A device used for the transformation of large volumes of sterile saline into icy slush in a chilled environment is provided. The sterile saline is provided in commercially available containers and the device has a movable assembly with a plurality of compartments, each sized and configured to receive one or more containers of sterile saline. The movable assembly is operable between an unactuated state and an actuated state so as to agitate the sterile saline in the containers during its transformation into slush. The partitions of the compartments are spaced away from one another to allow movement of the containers in their respective compartments. A method for transforming sterile saline into icy slush for medical, laboratory and surgical applications is also provided.
