Looking for liquid liquid extractor
I'd like to make some absinthe, amongst other isolations of natural compounds and I really want to get my hands on a good (but affordable)
liquid-liquid extractor.
Anyone know the least expensive / good supplier, or perhaps have one of their own up for sale?

What's wrong with conventional techniques, like distillations and use of separating funnels for extractions?

Distillations are sometimes hard to obtain smaller amounts - coating the glass walls.
Nothing is really wrong with either of these, but I'd like to just set it up, walk away and have it continuously extracting all the time. Minimal
work.
I think it would be funner to work with this too  it is probably more
reproducible as well than sep. funnel
OOPS! My bad I'm looking for a solid-liquid extractor. sorry was not thinking and typing at the
same time. i.e. a soxhlet

Do you mean a Soxhlet extractor?

Soxhlets can be found on eBay all the time at affordable prices. Especially if you're looking for the ones with US tapers.
This just in: 95,5 % of the world population lives outside the USA

Does anyone know the average volume of one of these? Is it around 250? 500 mL? I've never had one before and Laboy doesn't specify.

I checked the one that we discussed in PM, a 55/50. Volume in the extraction "cup" up until the point where the solvent drains is 200ml. The sidearm
carrying the boiling solvent vapors into the soxhlet is at the 300ml mark. You could comfortably pack the extractor to probably 250ml, though the
upper material would not be as well extracted since it wouldn't be immersed in solvent, just wetted from dripping solvent and cooling vapors.
