Dear Nicholas,
Three possible solutions that I have seen:
1. A sheet of stainless steel under the filling area over concrete
(I think I saw that at the ESRF).
2. A "throw-away" layer of linolium that you replace every few
months. Sort of like an ablation layer on a heat shield (that's what
we have here in our building, but I'm not sure how well it works; the
lino underneath is also cracked, but that may be due to infrequent
replacement).
3. Hard flooring tiles (ceramic, granite), or just plain concrete.
We have ceramic tiles under a storage dewar in our Proteomics unit,
but I'm not sure how often it's refilled, so it may not get the same
punishment that the area around a filling station would get.
If you find a solution I'd like to hear about it....
Harry
Can anyone recommend a floor coating that passes category 2
containment (ie not wood) that is resistant to liquid nitrogen. Ie
you can fill dewars on without cracking. Various solutions our
estates people have fitted have all proved unsatisfactory.
Bets wishes
Nick
