[labnetwork] Hydrogen Bromide Seal Compatibility

[John Nicholson]

I'm retiring this month after minding the UMass/Amherst clean rooms solo
since 2008 and have a few last minute equipment configuration issues to
complete.

HBr has been added to our RIE system and the line fitting is a CGA 330
while the tank ordered by a professor is a 634 fitting (nickel seals). I
have a 634 to 330 tank adapter but am unsure whether the Teflon seals used
with the 330 end would be compatible with HBr. Any advice would be
appreciated.

Best regards and thanks for the assistance over the years,
