There is one advantage I see using a soxhlet, and that is for an acid/water boil. It has the benefit of separating you bark from the liquid, simplifying the filtration part of the process. But soxhlet money would be better spent on a vac filtration/sep funnel setup.

I have them both, soxh, buchner apparatus and separatory funnel.
I had the same idea 1ce. Why not? what do you think about 12/13 soxh's cycles with acetic acid acq (1 N) ?
