Hi guys, I just did a series of pulls during an extraction. I did the solvent pulls and i believe it turned out well ( blowing on the solvent would make creamy white pools swirl amongst the yellow solvent ) .
I then left the precip container on my kicthen bench to evap.
I got distracted and left it for about an hour, Came back to it and most of the liquid had evapped. I could see a thin film of the creamy dmt settled at the bottom of the tray.
Now at this point is it okay to just put in the freezer ? Or do you need more liquid for xtals to form ??
( i always hate this part of extractions by the way, If i don't evap at all then i find that xtals never form in my precip tray after precip. )
I always gotta evap to see results, Today it just happened to evap the solvent faster than i thought leaving me with a tiny amount of solvent liquid. ( my precip tray has like 4 thimbles worth of liquid in it, The rest of it evapped into the white filmy layer ).
I assume that the white filmy layer is dmt. I also assume that i might get goo after freeze precip because of the white filmy layer, But i guess I'll wait and see.
Is this all okay or did i evap too much ?? ( without pictures i know it might be difficult for you guys to give an opinion ) .
So i guess my question is -after you've done your solvent pulls, Is it possible to evap it too much and have it negatively impact yield or possibly ruin an extraction ??
I chose to just put my precip tray in the freezer and see how it pans out.
I have a gut feeling that i might have made a big mistake by letting most of the liquid evap, But then again i could be wrong. ( normally i let about 50% of the pulls liquid evap, Today it evapped about 90% )
Thanks - As soon as i can do extractions with consistent results then I'll stop asking these beginner questions.
Hopefully my freeze precip turns out great tomorrow - i guess its still a pertinent question though as other people could run into the same problem. The guides on the nexus are great, But sometimes experience comes into it.
Cheers.
