does any one out there know a suffiecent way to get more yield?

Use more bark

what will more solvent do??

There is only a certain amount of DMT in the plant material. The teks most frequently used are effective at getting pretty much all of it out of the plant. More solvent doesn't change how much DMT is in the plant, it just means you have more solvent.

Funny you should mention this.

I normally follow the Q21 jimjam tek pretty much to the letter and I normally get a 1% yield.

Last week I used only vinegar and no water, i then allowed the acidification stage to sit for 2 days before basing. I then allowed the base stage to sit for 2 days before doing my normal 3x1hr limonene pulls followed by a 4th 24hr pull.
I stopped at 4 as the 4th yielded only 100mgs.

This resulted in a 1.5% yield. I was very happy

It was the same batch of bark.

Yeah, really it's just a matter of letting your bark acidify/basify for as long as possible, and then doing pulls until you stop pulling anything.

Not a bad idea to keep your bark mixture sitting for a while, agitating occasionally, for some time after you do your first set of pulls. You might get 95% of the DMT in the bark with the first set if you do your tek right, but time always helps scratch out every last bit.

Also, if your interested in the broader spectrum of alkaloids in the bark, using something like xylene and limonene will get you more yield, though perhaps not what you really want.

i always have the hardest time figuring out if the mimosa bark is all used up or im doing somthing wrong and getting a low yeild.

It might help if you describe your procedure in detail as well as your yeilds

well i keep getting really low yeilds like less than a bowl each time and i let the solution sit for about a day agitating it somtimes and then i roll it around and let it reform the 2 layers then i pull the layer off witha pipette and then freeze it for about 24 hours then i pour the solvent into another contanier and put the jar back with the lid off for about and hour and a half then when i com back theres only a couple white crystals.

How much solvent are you putting in the freezer? You want to reduce it via evaporation before freeze precipitation. Your goodies may be stuck in your solvent and just aren't crashing out.

so why is this happening

a very decent amount. more than less

and how should i exaporate this before freezing?

Just let it evaporate... ignore it for a few days and let nature do its thing. Alternatively you could use a fan or heating pad to help speed along the process. Whatever you do don't throw away your solvent because I'm 98% sure it is full of DMT

1.how many pulls do you do ?
2.how much bark,water,lye do you use ?
3.how much naphtha do you add it ?
4.how long do you leave it in freezer ?
5.how cold is your freezer?
6.do you reuse your naphtha or you always use new one ?

i did like 5 i used 30g of mimosa 30g of lye and like 900 ml of water because i have powder and not the root. and i did about 60 ml of bestine i leave it in my freezer for about 20 or so my freezer is a deeper freezer easily freeze ice cream rock hard. i always reuse my solvent.

You are using quite a lot of solvent, so the chances are that the reason you're not getting much from the freeze precip is because the solvent is not saturated enough. Before freezing the solvent, let it evaporate until it goes cloudy. Once the solvent is nice and cloudy then stick it in the freezer and more of the DMT should precipitate out of it. If the solvent was clear when you last done a freeze then that will be why you got so little out of it.

I would use less water for the future. The ratio I use and works well is 1g bark to 15ml water to 1g lye. Next time try less solvent maybe half of it. You can try to heat the solvent before you mix it with your solution. I take it that 20 means 20 hours right ?

if yes that should be enough. as the guy said try to evap a bit till its get cloudy and then put it back to freezer. Or you can evap it all. I would not reuse solvent many times. In fact I do not reuse solvent ever. Once I have done freezprecip I just evaporate all naphtha to get the rest.

There is really no reason not to re-use solvent, it saves money and it is better for the environment

Well I said only how I do it my self. Many people here reuse naphtha. I don't.

Some say naphtha loses potency to pull enough spice after many use unless you distil it and then use again. But this is not my experience.

I know how I do the extraction and it works every time so I must be doing something right.

My advice is from my experience its up to the guy to decide.
