No, afaik they're intended to be used dry
<davidc__>
offtopic for here; but azonenberg - you seem to know a bit about vacuum handling gear. How hard is it to take apart and reseal high-vacuum gear? [I bought myself a SEM and am trying to figure out how in hell to move it]
<azonenberg>
davidc__: No more offtopic than lekernel's question :p
<azonenberg>
I've used some vacuum stuff (and seen people abuse it lol)
<davidc__>
Got it for essentially free [and is in known working condition]
<lekernel>
SEM don't have such ultra high vacuum afaik
<lekernel>
it's just viton seals, not those difficult and expensive single-use copper seals
<davidc__>
lekernel: yeah; viton is what they use most everywhere; but the page in the service manual that discusses column disassembly is missing :(
<azonenberg>
davidc__: If it's low vacuum using viton gaskets, you should be good
<azonenberg>
Copper seals are used in UHV and some field emission guns might use them
<azonenberg>
But i would not expect to see them on a tungsten SEM
<lekernel>
at the MBE lab near where I live, they solved the problem of the sample insertion by having a first medium-high vacuum chamber with viton seals, and then some robotic system takes the sample through some special vacuum valve and puts it into the ultra high vacuum area
<davidc__>
Ok; thanks. Just trying to decide if I'm better off taking the column, ODP and baseplate off and moving everything in small manageable chunks; or trying to move it in one go.
<lekernel>
don't you want to see what's inside anyway, if not repair it? :)

lekernel: I want to see whats inside anyways; but I don't want to take it apart before making sure I really understand what I might be misaligning
