Soxhlet extractors are often coupled to a specifically designed condenser with a very large lower joint.
Is this inherent to it's function as a condenser in the apparatus or only because the Soxhlet Extractor part underneath it needs a big upper joint to get stuff in and out? In other words, is there any drawback to using an adaptor and replacing the condenser by a longer (but thinner) graham condenser?
Preventing flooding might be another reason (for high boiling solvents mainly?).
