I think u need to do more research
Heres a description of my first setup.
I dont break vac at any point.
This is a pic of my set up now. (Its always changing)
I swivel the three way adapter the reciving flask is attached to upwards when I start. I actually have a second drop down after now. The first is attached to a jacketed recieving flask so I can bump heads out of it while distilling. The second is to catch my heads after the terp fraction. Terp fraction gets tossed and heads and tails gets thrown into a bucket. When the bucket fills up, I run it
So u start with both facing up, then after terp fraction (166C on bf) I swivel the second one down to collect heads. Then when I hit main body (178C on BF) and theres no heads streaking across, I drop the jacketed recieving flask.
I have been advised against ln2 in the dewar because it doesnt work aswell as dry ice slurry and isnt the safest with glass. If u go with an SS cold trap go for it.
Yes David has the 24/40 to kf25 adapters, tell him u want them like I ordered second. (His bore size on the second version was identical or slightly larger than the beaker and wrench one I got awhile ago, and his are atleast half the price)
@strange Good idea on the freeze dryer, but since you will be sucking water out of there, I would advice getting a wide bore bottom. Something that doesnt narrow down to 24/40
I’ll have my second pump, and diffusion pump rigged up by the end of the month, with 3 cold traps between system and pumps. I’ll post pics and show progress, buying from David, saved me enough money to upgrade everything else in my system!
I saved another 1.5k last week from him!
