Abstract
A device for taking samples of noxious liquids, notably radioactive liquids. A protective enclosure (7) contains notably a circulation unit (10) in the form of a jet pump supplied by a driving arm (19). The liquid to be analysed is aspirated by an aspiration arm (17) and discharged with a drive liquid via a return arm (18). A sampling flask is pressed under a support plate (9) where the aspiration and return arms (17 and 18) emerge and closes the sampling circuit. This method is recommended above all for viscous liquids, liquid sludges and liquids charged with large size solid particles, since the sample only passes through pipes of an adequate diameter and is not subjected to any mixing or disturbance. A correct sampling is therefore ensured.
