Abstract
A head for taking liquid samples and intended to be used in a sampling system associated with a nuclear fuel processing installation, includes a sampling tank (10) in which is removably received a needle body (16), which supports a sampling needle, to which can be fixed a vacuum sampling container (46). The needle body (16) has an extension (34) provided with holes, which surrounds the lower part of the needle (18) immersed in a cavity (26) of the sampling tank (10). The lower end (36) of said extension (34) seals a draining passage (32), which opens into the bottom of the cavity (26). This makes it possible to ensure a larger liquid quantity.
