Separatory funnel makes separation of layer take a couple of seconds without needing to worry about accuracy with the pipette, and you can get it down nearly to the last drop isntead of always having to leave a bit that you cant accurately separate with a pipette. Also one thing is if youre doing a 100g extraction with 100ml solvent to pippette out, but it would become much harder if youre trying to extract some mescaline with a larger amount of volume, or makig a bigger mimosa extraction like 500g or whatever and with a large amout of solvent to pippette out.
And if you do some acqueous salting and/or washing of solvent, again it will save you more time and work. I would suggest getting a large one already, like a liter, not less....
Personally I think its great, and im sure you can find some things for cheap, maybe there's something in our suppliers section, or look through ebay, or just search around. Though Ive worked for years without one, so if yu dont have money and feel already good with your technique, then yeah maybe its something to leave for later.
Good work there with the equipment you got, im sure its nice to see it all set up on your extraction table
