Parameters are determined relative to two or three phase fluids. The sample (S) is placed in a tubular rigid sleeve (1), with two end closures (13,14), which also engage an internal elastic sheath (21). Fluids under pressure traverse the sample from two channels (15,16) and the sheath is pressurised (PO), to press radially against the sample. The end closures include detachable plugs, for access to opposite sides of the sample and to pressurise the sheath. Fluids may be circulated by a pump (39), providing a first fluid (e.g. water) and a second fluid (e.g. oil) from an injection column (28). Two burettes (33,36) may receive the displaced fluids from the sample and a supply assembly (43,46) provide gas to the injection column.
