Plateau border, definition

After the measuring cell is filled with foam to a specified level it is covered with the lid in order to ensure a vapour saturated atmosphere. Then the space under the filter is connected through a glass cock with the buffer in which a definite reduced pressure is created and controlled by the vacuometer. The liquid draining from the foam is collected in trap 7. Thus a definite reduced pressure in the Plateau borders is established.
