You could buy a 50 liter heating mantle, and put it on top of a 50 liter magnetic stirrer. You said you already found a stirrer, here is a listing for
a 50 liter mantle:
For a steam distillation at that scale, I would recommend a fabricated metal still, a motorized mechanical stirrer, and a oil or sand bath for
heating. If you get a metal still, then you could also heat by direct flame.

Why stir a vacuum distillation when you could just use an ebulliator? Pull a very thin tip on piece of glass tube (probably 3 of them for 50L) and
keep them submerged in the liquid and the other end open to the atmosphere. The vacuum will pull air through the tube at a very slow rate (assuming
you made the tip small enough) and prevent bumping.

Yes, exactly! I have had good results just using a Pasteur pipette. And the clamp is used to control the gas flow. This can easily be used with an
inert gas, if needed.
