What condenser for chemical reflux?

[xbnmx]

What kind of condenser would I require in order to boil chemicals at reflux while still being able to stir them (for example lysergic acid and diethylamine)?

You might try a liebig on the 2nd arm of a claisen adapter, putting your teflon stirrer-bearing in the first one.
Be careful with that example there, I hear in some places they'll burn you as a witch for stuff like that.

I'd use the longest condenser available, preferably one designed specifically for reflux.  Also, I'd use magnetic stirring unless there is some reason not to (like iron filings as a reactant maybe?).
