I agree with Bob. Conflat seals are good for very impressive vacuums.

Hi Dave,

This looks like standard conflat UHV gear to me.  The typical gasket used for 
conflats is a fairly thick copper ring that is sealed by compression between 
knife edges turned into the conflat faces.  In absence of a description of a 
special gasket material, I would presume it is the standard copper gasket.

Interesting results.  One question I have is what material is used as a gasket 
between the end flanges and the SS reaction chamber?  It is hard to believe 
that nothing is required to prevent leaks.

With further reading I see that some thin gasket was used.  I answered my own 
question.  Of course the type of material is very critical for anyone wanting 
to replicate the experiment.

The reactor definitely uses metal gasket seals. I couldn't remember what
metal, but copper sounds right.

There's all kinds. See:
