PROCESS FOR POSITIONING THE LIQUID IN A LIQUID MEDIUM CELL

摘要

The invention relates to a process for positioning the liquid medium in a liquid medium cell and to a corresponding cell. The cell comprises a liquid medium placed between two walls kept spaced from one another, e.g. by shims, and joined along the edge thereof, wherein it comprises first system for producing a first surface tension force in a first area and second system for producing a second surface tension force in a second area, the first surface tension force being higher than the second surface tension force, said systems serving to correctly position the liquid medium between the two walls, the liquid medium then being located in the first area and outside the second area.
