Abstract: A device for a cell of an apparatus for wet processing of a planar workpiece, comprises a structure comprising first and second walls. The workpiece is movable in a central plane through a space between the first and second walls in a first direction (y). Apertures for introducing pressurised liquid between the first and second walls are on opposite sides of the central plane and facing the central plane.
