Fluid sampling device comprising a sampling cell provided with a thermal control valve consisting of a plug made from a solid low-melting temperature alloy that is made permeable to the fluid by heating the metal alloy to its melting temperature. The device mainly comprises an intermediate cell with a central channel provided with a plug made from a low-melting temperature alloy which fits into the inlet hole of the sampling cell. A connecting device for connecting the two cells together and an element which connects the intermediate cell via a fine linking tube to a reactor producing the fluid to be sampled.

A mixture containing substances likely to settle or to flocculate is fed into a chamber (1a) of a body (1) delimited by a mobile piston (18) and a closed-circuit circulation of the mixture is established by means of a homogenization turbine (8) driven by a motor (28) associated with magnetic driving means (9, 26). According to the pressure and to the temperature, variations in the conductance of the mixture flowing between two electrodes (1, 16) connected to a measuring device (17) are measured on the one hand and variations in the driving torque applied to turbine (8) under the effect of the concomitant variations in the apparent viscosity of the mixture are measured on the other hand. The cell can be used to study of the conditions of formation of asphaltene deposits or flocculations in petroleum crudes for example.

A cyclone separating device includes a transparent and tapered separator flask, with an upper outlet where a tube provided with seal means and a tubular extension is fastened, and a lateral inlet through a lateral appendix communicating with the inside of the flask through a fine channel offset in order to generate a cyclone effect promoting the separation of the phases and lined with an insert made of a plastic material. The fluid sample is injected, for example, through a septum by means of a hollow needle guided through the insert. The device can be used for processing geologic fluid samples.

Fluids kept under high pressure in one or several balancing cells (C1, C2) inside a thermostat-controlled enclosure (14) at about 200.degree. C. are extracted by introducing into the enclosure a sampling cell (1) capable of withstanding pressures of the order of 150 MPa, fastening cell (1) to a connection element (24) linked to balancing cells, taking samples and removing the cell from the thermostat-controlled enclosure, with all of these operations being easily conducted from outside. After possible weighing of the sampling cell, a transfer device thereafter allows the sampling cell to be communicated with measuring and analysis devices such as a gasometer associated with a separating bottle, a solvent injection means, etc. Operations are synchronized by a programmed microcomputer (MC). The preferred application is processing geological samples.
