Abstract:
1. A device for fluid treatment of a plate-like article comprising: a rotary head for holding and rotating a plate-like article around a rotation axis; drive means to suspend and drive the rotary head without contact, the drive means being arranged radially around the rotary head; a first media supply means to supply media to a first side of the plate-like article; a substantially cylindrical wall, which is substantially concentric to the rotation axis, wherein the substantially cylindrical wall is arranged between the rotary head and the drive means and is introduced in the gap between the rotary head and the drive means, wherein the substantially cylindrical wall is part of a closable chamber, so that the plate-like article can be treated at a selectable pressure different to ambient pressure; and axial moving means for axially moving the rotary head and the substantially cylindrical wall along the rotation axis relative to each other, wherein the closable chamber comprises an openable cover sealed against one end of the substantially cylindrical wall for picking and placing the plate-like article onto the rotary head, wherein the axial moving means, the substantially cylindrical wall, rotary head and drive means are arranged relative to each other so that the rotary head can be moved along the rotation axis so that the plate-like article is moved to a position not within the space surrounded by the substantially cylindrical wall and where the plate-like article is accessible for removal from the rotary head.
