An outer sleeve 36 is secured to the member 26 and defines therewith an annular cooling chamber 30. Coolant, e.g. water, is supplied via conduit 40 and discharged via conduit 41. The member 26 adjacent its other end is provided with an inlet 68 for an inert gas, e.g. nitrogen. In use, the apparatus is secured by means of flange 31 to the wall 17 of the vessel with the channel section 44 positioned within the vessel. A sample of the material falling within the vessel will enter the channel section and subsequent movement of the pusher plate 56 in direction A will cause the sample to be displaced along the member 26 and through the outlet 50 into a container 53 detachably secured thereto. |
