Abstract
To take a sample of liquid and/or gaseous hydrocarbon at the surface or down an oil well, use is made of a flexible bag suspended by a tube from a top region of a wall of a closed receptacle. The bag and the tube are made of a flexible material that is leakproof and inert relative to the sample to be taken, such as a cross-linked polymer. The volume of sample admitted into the bag is controlled so as to avoid stretching the wall of the bag.
