Abstract
A well fluid sampling tool (5) having a sample chamber (315) at least partly contained within an at least partially evacuated jacket (160, 165, 170), the outermost wall (160) of the jacket (160, 165, 170) being adjacent to or forming an outermost wall of the tool (5). In such a tool (5) the evacuated jacket (160, 165, 170) acts to maintain the sample as originally retrieved, e.g. in single phase form (at original temperature).
