Abstract
A method for freezing a liquid located in a container, in particular a liquid drug, includes exposing the container to a cooling element such as cold gas in order to freeze the liquid. The cold gas preferably flows around the container, and/or the liquid is cooled in another way in order to freeze the liquid. The container is insulated at a surface of at least one first volume portion of the container, and the container is cooled nearly immediately at a surface of a second volume portion of the container by the cold gas such that the liquid freezes through later in the at least one first volume portion than in the second volume portion.
Claims18
A method of freezing a liquid drug disposed in a container, the method comprising:
- cooling the container for freezing the liquid drug;
- insulating the container at a surface of a first volume portion of the container by fitting an insulation body on the surface of the first volume portion in a lateral direction;
- and
- cooling the container by applying a cooling element at a surface of a second volume portion of the container, the second volume portion being located at a center of the container and the first volume portion extending from the center of the container to the edges of the container;
- wherein the container is cooled so that the liquid drug freezes therethrough in the first volume portion later than in the second volume portion.
