The Pressure Cell
Overview
WARNING: TA Instruments' Pressure Cell is designed for use at temperatures up to 150°C
and pressures up to 138 bar (2000 psi). At all times during the use of the cell, wear safety
glasses and clothing that afford adequate protection against the sample under test, and
the temperature and pressure used. At other than ambient temperature, the outer
surfaces of the cell may become very hot or cold. When operating at these temperatures,
wear gloves that afford adequate protection against the surface temperature of the
pressure cell and its fittings.
The Pressure Cell is used with the standard concentric cylinder, Peltier-controlled, heating jacket. A copper
sheath is fitted to the cell to ensure good heat transmission between the jacket and the cell.
The Pressure Cell may be used either in self-pressuring mode, in which the pressure is produced by the volatility
of the sample, or in external pressurization mode, with an applied pressure of up to 138 bar (2000 psi). In this
chapter, the pressure cell assembly and operation for both modes are described.
NOTE: For external pressurization, the user of the cell is required to provide a high-pressure
source, and suitable pressure-rated connections to a 1/8-inch or 1/4-inch NPT female fitting.
