Abstract
A sealing for a reagent container and provides a sealing plug which can be adapted to the respective reagent container. Within the meaning of the present disclosure the terms plug, and stopper will be used synonymously. A liquid which is deposited in a reagent container like a vial or tube is protected by a plug from both, evaporation, and oxidation by ambient air during its presence in the reagent container. In addition, when the reagent container is provided to the analyser, the plug reduces evaporation and oxidation of liquids like reagents. A system comprising the plug and a method for using the plug are also disclosed.
