Abstract
Apparatus 1 for sampling the contents of a pressurised vessel 2 comprises a valve 3 having an inlet 4 and an outlet 5. The inlet 4 is in communication with the interior of the vessel 2. A sample-receiving pressure receptacle 7 is connectable to the valve outlet 5 in a sealing manner, and a pressure venting line 8 is provided for equalizing the interior of the receptacle 7 with the atmosphere. When the valve 3 is open, a sample of pressurized vessel contents can enter the receptacle 7. When the valve is then closed, the sample remains in the receptacle 7. A probe 31, operable from outside the pressurized vessel 2, is provided so that, when the valve 3 is open, a sample of the vessel contents can be drawn through the valve and into the receptacle 7.
