Dry compressed air
Dry, compressed air is required for pneumatic grips. Typically, 90 psi air is required with
a water trap/filter.
Water supply
A water supply may be required for some specimen grips and some temperature control
systems.
Liquid nitrogen and carbon dioxide
A liquid nitrogen (LN2) or carbon dioxide (CO2) supply may be required for
environmental chambers with cooling options.
For carbon dioxide, tank pressure must be approximately 725 psi. It must be in a liquid
state when it reaches the valve of the environmental chamber.
For liquid nitrogen, tank pressure must be between 5 and 10 psi, depending upon the
regulator and relief valves that are fitted to the dewar flask. Do not exceed 20 psi.
