inert gas bubbler question
Here's the type of bubbler I'm thinking of replacing the balloon with. If I use this how do I apply a high vacuum before admitting gas without
pulling oil into the system?

If I where you i wouldn't bother with those expensive bubblers, just use a cheap gas outlet tap like this one:
and use some tubing to connect it to a small wash bottle with some oil in it, or a small simple bubller.
You can then just close the tap when pulling vacuum, shut vacuum and apply inert gas (with another bubbler) until the flow starts to slwo down, an
dthne open the exit tap to the bubbler. The oil will always be saturated with argon, so no problem on that side.
That's what I have always done, and never had any problems. The type of bubbler you posted in the kind that is used on solvent stills, where vacuum is
very rarely applied, but there is a constant flow of nitrogen.

Use a torion or whatever then lead that to a safe-purge valve (link below) they are life savers, expecially for evacutating a vessel and back flushing
with N2.
