A device is provided for taking samples of a pressurized gas or liquid product, comprising a first through flow duct for the product to be sampled, a second through flow duct for a carrier gas or liquid, a communication conduit between said two ducts and a controllable means for normally closing and temporarily opening said communication passage. For injecting and vaporizing a liquid in analysis circuit, the device further comprises means for heating at least the downstream part of said communication conduit, i.e. that by which this latter is connected to said second duct through which said carrier gas or liquid flows.

Automatic pressurized fluid micro-sampling and injection device

Rheometer for effecting measurement of rheological properties in a medium, comprising a hollow body (2) having an inner chamber (3) with a lower zone (3A) and an upper zone (3B) of enlarged diameter. An inner shaft (9) is located in the inner chamber (3) and is driven by a magnetic coupling (12A-13) through a cap (4) for hermetically sealing the hollow body (2). A rotor (18) is provided on the inner shaft (9) and is displaceable in a longitudinal direction between an upper position where it is located in the upper zone (3B) and a lower position where it is located in its position for measurement. A stirrer (10-11) is keyed to the lower part of the inner shaft (9) and is receivable within the rotor (18).

Rheometer for measuring high pressure and high temperature with sampling

This device comprises (a) a removable compact cell which can be accurately weighed. A sample is introduced into this cell, with the cell equipped with a magnetic stirrer and with at least one measuring gauge. This cell has a sliding cover plate for varying its volume. The device includes (b) a pressurizing unit whose temperature can be controlled and which is provided with a housing for receiving the cell. In combination with the above, there is provided (c) a calibrated hydraulic press operatively associated with the sliding cover plate to compress the fluid contained in the cell.
