Abstract
In a method for freezing a liquid located in a container, in particular a liquid drug, the container is exposed to a cold gas in order to freeze the liquid. The cold gas preferably flows around the container, and/or 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.
