I'm looking for a cold finger now, will have to wait for next paycheck since I already have my 3-neck round bottom flask coming. Kinda want that so I can have a more accurate temp. reading because I know how I have it at the top of the column near the condenser is not accurate enough for my liking at least.
My question is that I see they have some configurations available for leibeg or allihn condensers, would it be advantageous to have the extra condenser? I'm guessing it wouldn't since your emphasis on size but I think maybe you were just referring to the it's size comparatively and not necessarily a comment on requirements of the apparatus as a whole...
This really gave me a good understanding of the process I think:
Cold Finger Sublimation Explained
I was looking at something like this for my setup:
200mm Cold Finger at CtechGlass
Since I have the kinda playschool organic chem. set in that it's actually 24/29 and not the standard 24/40 but when I bought the kit it specifically stated that all parts would work interchangeably with the standard 24/40's out there. So I think I can get something like the above OR something like this:
110mm Cold Finger for Allihn Condensers
and then pickup a standard allihn condenser? I would defn. want one with a vacuum attachment if possible.....
