Abstract
A method for centering a drop of liquid on a given point on a surface. The inventive method consists in forming a bell-mouthed recess, whereby said recess has a curvature at any point at the limit of contact between the drop and the recess that is lower than or opposite to the curvature of a circle (TC) that is tangent to the surface of the recess to said point and at a symmetrical point (CP) of said surface.
