Extraction body for lithographic apparatus

An extraction body for a support apparatus of a lithographic apparatus, the support apparatus configured to support an object,

• wherein the extraction body is formed with an opening at a surface thereof,
• wherein a first passageway extends within the extraction body from the opening and the first passageway is configured to fluidly communicate an extraction channel in the extraction body to liquid between the surface and the object,
• wherein, in a use of the extraction body, a first pressure in the extraction channel is less than ambient pressure, and
• wherein at least a part of the first passageway is sized and dimensioned such that when the liquid enters the first passageway via the opening, a second pressure in the first passageway associated with surface tension of the liquid is lower than the first pressure while the first passageway is exposed to the first pressure such that at least a portion of the liquid is retained in the first passageway despite an underpressure in the extraction channel sufficient to remove all of the liquid at the opening through the opening and the first passageway.
