The invention relates to a method for the application of at least one voltage pulse to at least two containers fitted with electrodes, by means of which at least one voltage pulse is applied to at least one container, while at least one other container is subjected to a preparation or a post-processing. According to the invention the method comprises mutual exchange of the respective positions of the container to which a voltage pulse has already been applied and the further container. Furthermore, the invention relates to a device (1) for making electrical contact with at least one container fitted with electrodes, with at least one receptacle (3, 7) upon which at least one container can be set, and with at least one contact appliance (8) for making contact with the electrodes of the container. According to the invention at least two receptacles (3, 7) are provided, wherein one receptacle (7) is located at or inside the contact appliance (8), and wherein both receptacles (3, 7) and/or the contact appliance (8) can be moved such that after completion of the movement the other receptacle (3) is located at or inside the contact appliance (8).
