It should come off on the rot. evap. if the pressure on yours goes to close to 0 mbar. Turn the water bath up to ~70oC and add a *Ignore me, I am impatient* trap between your flask and the rot. evap. itself, under those conditions it should be pulled as far as the *Ignore me, I am impatient* trap at least before condensing. But make sure others don't mind you using the rot. evap. under those elevated conditions and wash it afterwards if for nothing else than to get rid of the smell.

And would someone like to tell me why the post was edited? Would have been nice to at least have been informed..

This is automatic. Kind of an easter egg. One day I might dig into the details and remove it.

LOL...I thought that "Ignore me, I am impatient trap" is a pretty good description of the role of the, errr, blump trap, in  this description.

I admit I had to check what was the word that was replaced. "bumр" is being censored as it is usually used by people bumрing their threads that didn't get an answer yet.
