Sorry if i'm asking old questions, but i'm busy with my first extraction and i'm having a really hard time separating the naptha from the base. I'm extracting from 100g of Mimosa in 1.5 liter of water, and use 75-100ml Naphta for each pull. First i had everything in a 4 Liters glass jar. Because it was so wide, the solvent only reached about 1-2 millimeters above the base so it was quite impossible to separate the solvent without getting any black stuff. So i poured everything in a 2L milk jug. But still, it's pretty hard, especially for the last few millimeters, to get al the solvent out without getting the black stuff.
I know it's probably a frequently asked newbie question, and I just need to have patience and see what works for me best. But I hoped maybe you guys have some tips?

Drain out all the bottom water layer until there is very little left. Then pour that small amount of naptha/water into a glass and seperate it with a 10ml syringe.

Spend thirty bucks on a separatory funnel.

Are you doing a STB or A/B extraction?

I'm doing a STB extraction.

Thanks for the tips

you can freeze separate the stuff.... the basic water will freeze while the naphta will not
