Abstract
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.
Claims10
A device for determining physical characteristics of a fluid, such as its liquid-vapor equilibrium pressure or its volumetric mass, said device comprising in combination:
- (a) a removable compact cell (1) adapted for being accurately weighed, said cell (1) comprising means (6) for introducing the fluid and means (8,9) for homogenizing and stirring the fluid contained therein, at least one measuring gauge (7), and said cell having a slidable wall (2);
- (b) a pressurizing unit (10) adapted for having its temperature controlled, and provided with a housing (19) for receiving said removable cell (1);
- and
- (c) means for reducing the internal volume of said cell (1) comprising calibrated compression means (33) associated with said pressurizing unit (10) and operatively associated with said slidable wall (2) of said cell (1) for compressing the fluid contained therein.
