The Pressure Cell
The Pressure Cell is a sealed vessel that can be pressurized up to 138 bar (2000 PSI) over a temperature
range of –10 to 150°C. It can be used either in self-pressurizing mode, in which the pressure is produced by
the volatility of the sample, or by externally applying the pressurization, typically with a high pressure tank
of air or nitrogen gas. All necessary plumbing and gauges are included as a manifold assembly. The
Pressure Cell is ideal for studying the effect of pressure on rheological properties, as well as studying the
materials that volatilize under atmospheric pressure. This option is available for the AR-G2 and AR
2000ex rheometers.
Refer to the Pressure Cell Getting Started Guide for additional information.

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.
