Having trouble getting my crystals to stick to dish..

Migrated topic.

This is my latest and probably best yield, haven't weighed it out yet but it appears to be almost double what I have been getting. I've been using heavily reused naphtha I think that's what's causing the off-white color. 50g ACRB using Cyb's tek. But I always seem to have this issue where the crystals form and about 30% make it to the dish and the remaining 70% floats in the naphtha. This is after 14 hours in the freezer at -6*f. When it's done evaporating I'll weigh it out.

My problem used to be dissolving crystals while filtering. I can't say for sure if I've found my solution since I only tried it on this extraction but I just let it filter into a jar in the freezer. Those clumps dried out to the nicest looking extraction I've done this far. I guess you can read and read but until you do it for yourself you're gonna run into unforeseen issues.

You mean the crystals are floating in the solvent rather than stuck to the vessel I presume. Just pour through a coffee filter when you decant.

Filter through a coffee filter, save your coffee filters (they will contain a small amount of DMT), then eventually either soak the filters in warm IPA and evap or use them for changa blunts! :thumb_up:

Are you getting a 1%-2% yield?

This one was .743g from 50g of ACRB. So about 1.5%. I have been getting about .05% yield.

How many filters should I save before I try getting some dmt out of them? I have five at the moment.

Ah I just learned something from your thread replies :) I had the problem of the floaty crystals too on my first attempt. I filtered but I ended up with a yellowish crusted filter and couldn't think how to use it. Too bad I threw it out.

From now on I'll soak it in IPA and dissolve. AWESOME! I feel dumb for not thinking of that. Teks should have that method/option in them about filtering floater crystals!

Is this a problem? I find the xstals which don't stick easier to work with as they will dry a lot quick and are easier to get out the dish.

I use a pipette to suck up 90% of the Naphtha, then tip the dish at an angle so all the xstals which float, float to one end of the dish, then slowly tip the dish back so JUST the Naphtha runs to the other side leaving the xstals behind.
Then suck up the remaining naphtha with the pipette and your done.
Your xstals which were floating should dry a lot quick than the ones stuck to the dish, just make sure they don't blow away when you dry!:shock:

Hopefully that helps:thumb_up:

Don't wait to long, in the filters, the DMT has a lot of surface that is exposed to air, accelerating degradation.
You should best wash the filter soon after the naptha has evaporated from it.

You can use any alcohol that evaporates cleanly, but do note that some alcohols are denatured with denatonium benzoate, a substance that is extremely bitter even in very small amounts. I wouldn't want that in my DMT.

Acetone also works for flushing the filters and is generally not denatured with involatiles.

You can save up for as long or as short of a time as you want to, but I prefer to save up for a while so that the yield isn't tiny. I have soaked filters that were a little more than a year old and there was no noticeable loss of potency or change in physical appearance, so if any of the DMT oxidized it was a minuscule amount. Just store them in a sandwich bag or other reasonably airtight container and they'll be fine.

pitubo does have a good point though, my first post was typed under the assumption that everyone knew to check the MSDS before using any chemical. For this application, 99% IPS is not necessarily required, but I tend to stick with 99% for all applications anyways.

On a sidenote, I once recrystallized some plain salt (NaCl) and poored the hot solution through a coffee filter into three jars. I noticed then, that the first jar was noticably more clouded than the other two. There being no difference otherwise between the solution and the jars, I reasoned that the cloudiness must have come from the filter.

Since then, I always wash coffee filters with hot water before making coffee.

I don't know if the stuff that comes out of fresh filters when washed with water is released by naptha, alcohol or other solvents, but I reckon it's worth mentioning anyway.

My guess about the composition of the stuff coming out of coffee filter paper, is that it is likely some form of starch, possibly modified starch, used as a glue in paper making. It should be food safe, but I'm not sure what its effects are when heated/smoked.

This sometimes happens with my extractions too. I just tilt my precipitation vessel and allow the loose crystals to sink to the bottom of the solvent in a corner of the dish, then slowly pour the solvent back into a bottle, through a funnel, for reuse. A few tiny pieces do go into the bottle, but it is negligible, and as I'm reusing the solvent, they've not been lost.

It's also a matter of nucleation sites: scratch (but don't gouge!) the surface of your dish lightly but vigorously with a fork before use, and you should get a nice layer of crystals on the glass with the next attempt.

You only have to do this on the one occasion, and the microscopic irregularities should help promote crystal formation on the dish surface from then on in.

IME the rate of freeze precipitation has something to do with whether it sticks or floats. Straight from warm to deep freeze = mostly floaters. Warm > room temp > fridge > freezer = stuck.

This - slooow cooling - certainly helps for the formation of larger, cleaner crystals. Use an insulated container to help reduce the rate of cooling even more.
