Tomorrow I am getting some 1L volumetric flasks, when pulling time comes I will put half of the soup in there and another half on another one, and will pull from there. As its neck is very thin, pulling may be very easy. Will share results.

My friend has a similar problem when he carries out extractions due to his glassware.

He tells me that to get around this, he carefully watches his pulls when he sucks up the solvent. If the pull is clean, it goes directly into the evap. tray. If he gets some base soup in it, it goes into a shot glass. Once the pull is complete, he then pours (or sucks up) the solvent from the shot glass into the evap. tray. It's much easier to separate like that and means the amount of solvent lost is minimal.

Did a second extraction, with all the issues of the first one in mind.

Changed a bit the procedure, made a 3h acid cook before f/t, then proceeded as in the first one, but with the necessary ammount of water and no more. Used a bit more of acetic acid (120mL total), and doubled ammount of salt, in order to scale it to the water volume.



Proceedes as you said, and pulls were way more cleaner. Managed to minimise the total ammount of impurities, so only a small part of the product needed re-x.

Final yield was 1.5%, golden crystals. Then some clear sticky oil strongly smelling of DMT (definetely not goo) was obtained by evapping the solvent. This has been infused onto 0.5g caapi leaves. Thank you all for your comments and advice!

What I use to get the last little bit of solvent is a cheap seperatory funnel bought from an auto-parts store, and a small siphoning ball, also from any auto-parts store.....I use 1/2 gal canning jars, and ran into the same problem because of the width.

Will definetely give the sep funnel a try, have heard good things of it.
