What gasses do I need to run my glovebox? 

In standard applications an inert gas supply of 6bar (80-90 psi) is required for operation of the system. Acceptable gasses for system use are Argon, Nitrogen and Helium.

The systems will also need a forming gas supply for regeneration of the purifier column. The gas should be 3%-10% hydrogen with the balance being the working gas used in the system. The forming gas should be supplied with a low range regulator
(approx: 0-20 psi) so that flow can easily be adjusted when starting the regeneration process.
