Liquid/liquid extraction equipment uses less solvent but has the overall effect of some of what you've been thinking about.

On left is for lighter than water solvents, heavier than water on right. Some kind of condenser is fitted on top. They've made it deliberately a bit unclear so it's hard to copy a few crucial bits at the top, I think.

There's probably some way of mocking up a similar setup at home if you don't want to spend hundreds of currency units on a brand new piece of laboratory apparatus...
