Le côté extérieur du conteneur (1) présente une couche intermédiaire (12) dotée d'un orifice d'entrée (13), d'un orifice de sortie (14) et dans laquelle se trouve un corps liquide renfermant un mélange de matériaux absorbant les micro-ondes. Selon le procédé, une fois que les matériaux sont entrés dans le conteneur (1) de la cavité micro-ondes (7), le mélange des matériaux absorbant les micro-ondes permet d'obtenir un corps liquide qui va entrer dans l'orifice d'entrée (13) jusqu'à la couche intermédiaire (12) de manière à former une couche absorbant les ondes périphériques de stérilisation. Le rayonnement micro-ondes agit sur la couche absorbant les ondes et la couche de matériaux de manière à réguler l'épaisseur de la couche de matériaux qui, après stérilisation, sont évacués par l'orifice d'évacuation (4) du conteneur.
