This device takes a liquid sample from three different locations within a vessel, all at the same time. The sample is therefore more representative of the total content of the vessel being sampled. If any separation of solids and solvents has occurred during vessel storage, this sampling device prevents collection of an incorrect sample, for example, as would occur when the sample is taken off the top of the vessel. Sample fixture 10 is inserted into bottle or drum 11, and secured in place. This operation is done with the drum in the vertical position (not shown). The drum is then tilted to the horizontal position, as shown. Liquid 12 now flows through tubes 13, 14 and 15 and is poured into sample container 16. The liquid is thus sampled from three different areas of the drum at the same time.
