Definitions

  • the invention relates to a plug for a container for use in freeze-drying, also referred to as lyophilization.
  • a solution with appropriate ingredients is first prepared and this solution then dried in a freeze dryer.
  • the solution is an aqueous solution.
  • the solution is first filled into a container, for example a glass cuvette or glass bottle.
  • a plug is usually inserted into the container in order to completely close it for freeze-drying or after freeze-drying.
  • the plug is designed such that the freeze-drying process, a gas exchange between the container interior and the environment is possible. This can be achieved, for example, in that the plug in the process of Freeze-drying is only partially inserted into the container, and thus the container is not yet sealed. In this way, during the freeze-drying process, the solvent may be removed from the solution to dry the ingredients of the solution. Following the freeze-drying process, the plug is typically pushed further into the container with the aid of a device formed in the lyophilizer, so that the bottle is then sealed tightly thereafter. Often, a fuse closure is then attached to the container to secure the plug. This securing closure may be, for example, a crimp cap or a screw cap.
  • a plug for use in a freeze-drying process is known, for example, from the document DE 20 2011 050 413 U1 known.
