More naptha for easier pulls?

[witchdr11]

I see alot of people having issues with their naptha layer being thin and difficult to extract the Spice layer from the top without getting in basified liquids too. Couldn't someone just use more naptha than required to make the pulls easier, at least for the first few pulls?

I understand that most freeze precip, but if easier pulls were more important for individual circumstance like container width/size making pulls of thin layer difficult, couldn't one just evap off a bit more naptha before freeze precip?

Another question/observation. I have seen another issue which is after precip, people pour off over filters and the now warming naptha dissolves the crystals again. Could this be averted by pouring off the naptha and letting it strain through at a lower temperature, like in the freezer? Thanks !

Sounds like good advice to me. I am listening

[real_psily]

I think it is better to add more basic polar solvent to elevate the non-polar solvent into an area of smaller diameter. like raising the point of interface into the neck of a volumetric flask then the organic layer is much easier to remove. If you need to you could transfer the last little bit-o-organic layer with some of the polar solvent into a test tube or other tall thin cylinder for easier separation.
As for the second part you lost me a little. mostly the xtals stick to the glass and the solvent can be decanted off leaving xtals behind. If you were to filter you would do it cold. Then to free the xtals from the filter you could use fresh warm naptha and recrystal from there.
hope that helps

To clarify I mean people who are pouring crystals and naptha onto a coffee filter. Are the crystals easily removed from the coffee filter despite it having some of the solvent on the filter?

You will be able to get most of the crystals off the filter (SWIM drys on the filter then moves on to purification/storage) There will be a small amount of spice infused into the filter. Guess you could smoke the filter. IMHO using excessive solvent won't be an issue as far as yield. Just added expense and time to evaporate.

Red Lobster used to have these great plastic novelty cups that had a great bulbous base and a loooong thin neck. Someone wishes he still had one as it seems the perfect shape for pulling solvent layers off.

If you wait 30 minutes the filter paper will dry out and the crystals will fall right off. but you do need to filter it cold!! Strait from the freezer to the filter.
I'm always surprised how much is NOT lost in this process!!

I use the same naptha for 3 or 4 extractions and then evap it. There is usually a little more spice there after I evap.

By the way, I got my 500ml seperatory funnel from Ebay for $30.00 with shipping!! I would not think of doing an extraction without it, makes the whole process so easy!!

Yes, This has been suggested in the past...IMO, Adding more naptha on your last pull is the ideal if a 'bottle neck container' isn't what you have.

I understand that most freeze precip, but if easier pulls were more important for individual circumstance like container width/size making pulls of thin layer difficult, couldn't one just evap off a bit more naptha before freeze precip?

If you used extra naptha; this is a must because if you dont evap it down the Naptha won't let go of the DMT and your goodies wont 'fall out'.

Another question/observation. I have seen another issue which is after precip, people pour off over filters and the now warming naptha dissolves the crystals again. Could this be averted by pouring off the naptha and letting it strain through at a lower temperature, like in the freezer?

Yes, that would work out great. But most folks don't have a walk in freezer and the small one they/we do have is less than ideal to work in..

Coyote, thanks for your input, I think you understood all of my questions to the nines.

A shapely bottle if I do say so myself.

me personaly i use arizona tea 1 gallon tea jugs [plastic] i use enough water to leave 4in empty in jug and about 2 in of naptha [2 in because at top of jug it gets narrow ] so when i'm ready to seperate i get a 3 gallon plastic trash can and take my tea jug over the 3g can and squize my tea jug until all of naptha [containing the spice] spills out into the 3 gallon can leaving only a mynute amount of naptha in tea jug as to not spill any black into my 3g seperation can . easy as pie fuck tryin to use turkey baster and suck it out

Using plastic is VERY questionable when performing any kind of chemical
reaction.

not true. if SWIM uses HPDE #2 it perfectly safe to use with a variety of comon solvents...ie...naphtha, xylene, toulene, sodium hydroxide. In some cases it's safer to use than glass. they are chemical resistent, and commonly used in chemical supply storage and chemical warehouses all over the world.

Perhaps it's true, but maybe it's not a good idea to tell a bunch of people
online to use plastic jugs for chemical reactions unless you are specifying
the safety of the plastic as opposed to unsafe plastics.

I don't know much about the lab, but I do know I haven't seen many plastic
containers being used in labs.

[carpet face]

i have used the same plastic tea containers for over 30 pulls each. the only bad thing with the plastic is that while waiting for naptha to seperate , pressure builds up inside so i have to relieve some pressure during seperation[open the tea containertop to expell gasses].never had the plastic melt wear thin or anything negative like that .

[carpet face]

arizona 1 gallon tea container , i use aaa sodium hydroxide, and pure naptha from homedepot or ace or wherever .i do straight to base tek .so only chemicals are water naptha sodium hyroxide and mhrb
i have also used plastic milk containers .never had a problem oh yea i do evap in glass makes for cleaner spice when scraping.[i don't like smoking plastic scrapings my dam self]

your questions were pretty much all answered, i'm just including this tip to aid those without real glass.

sometimes a large syringe can be used to suck up a thin layer. my cat has used an old spore syringe to get that last little bit. it will act like a sep funnel some too so if you pull a little polar up with the naptha it's easy to squirt it out.

[Delafonze19]

I trust plastic like the milk jugs but I do not trust the ruber and plastic in a syringe. I have seen that shit melt.
