Device for determining physical characteristics of a fluid, such as its liquid-vapor equilibrium pressure |
摘要 |
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.
