Are A/B teks less efficient than StB teks?

Hello,

I've been tinkering with lots of different teks over the years. I settled some time ago on a variation of the Cyb's and ChemisTryptaMan Salt Tek.
If you follow it as described, this tek is a AtB tek, without filtering of the plant material.
Some time ago, I discovered the benefits of filtering the plant (lower volumes to work with, the ability to process more source material at the same time, less chemicals involved, and cleaner pulls).

Recently, I've got some new MHRB and split it with a friend. We both did an A/B tek, and the yields were way lower than expected (a measly 0.1% for my friend). I have no doubt that he must have made a mistake, it was his first A/B, and probably burned some of the plant material, because our source was the same, and I got a low, but decent yield around 1%.

He said he's gonna StB the rest of it, because that worked in the past. And that got me wondering: Are A/B teks less efficient by default? I mean, we're filtering the plant in the first steps. Is there more DMT to extract from there, that we're throwing away too soon?

I'm performing a test StB extraction on the same bark, so I can compare to the A/B results. In the past, I've gotten over 2% using StB, but can't remember how was the A/B yield on the same source material.

My method is not very scientific (no exact side to side comparison, the lenght and temperature of pulls is different), but I'm using the same materials. I'll have a yield number in the next couple of days.

So that's my question for you all: Do you think AtB and StB are less efficient than A/B with filtering? Maybe StB yields are higher because they're less clean?
 
If done to exhaustion they should be the same since the content will not increase nor decrease unless you lose material or burn sensitive alkaloids. With A/B you would do water or acid pulls of the dry material and still save it since you likely have not extracted everything. The acid water can then be filtered and based to pull. Assuming the solubility in acid water is high you should have pulled a large portion then base to freebase and pull with NPS. The starting material you had you can just do a normal 'stb' adding a little extra since you first need to neutralize the acid. You can then pull with your NPS as you normally would.

I personally prefer A/B since I can reduce the volumes and solvents quite a lot compared to STB. The actual yield you get will depend on the quality of the starting material.
 
Well, yes, assuming full exhaustion I know the yields would be the same, but I'm asking in a practical sense of the word. Let's say, 3 acid extractions on the plant material before filtering it out.

Do you think the A/B tek yield almost the same the yield as an StB performed on the same material? Assuming proper technique.

I prefer to do A/B since I first did it, but I may (or may not) be throwing away lots of actives with the plant material.
 
Not all A/B Teks filter. I use max ion and never filter. It's not required by the tek. I do think that filtering will leave actives in what has been filtered out. Thus lower yields. I like the acid phase as, to my understanding, it's a good precursor to release the DMT from the plant matter.

This is the difference (as I understand it) between AtB and A/B. AtB is what Cyb's tek does, but A/B is filtering the plant before basifying.

The practical difference between both is, after filtering, you can reduce the acid phase to a minimal amount, and that emulsions are pretty much impossible if there isn't plant material to cause it.
 
I have new (provisional and unscientific) data points:
- My last extraction (A/B) on this same bark yielded around 1% after 5 NPS pulls.
- This test extraction (AtB) has yielded 1.1% on the first 3 NPS pulls, and I know for sure there is way more to extract from there. (I'm using minimal NPS)

It seems like filtering the plant material after only 3 or 4 acid pulls is not enough to get all (most) of the actives out.

On the other hand, the extract from the A/B tek is as clean as it can be (clean transparent/white crystals), and this AtB extract is also pretty clean crystals, but they have a much darker color.

Interesting. My AtB are typically pretty white and crystalline. I wonder what the difference could be.

I might have overstated the "darkness" of the AtB crystals. They're white/yellow, and crystalline. As I said, pretty clean, I only said it's darker because I'm comparing with my A/B crystals. And those are almost transparent or pure white flakes.

I don't think there is a significant quality difference between both, but they do look different. The smell is also a bit different, the A/B ones smell a little nicer to me. I know, pretty vague and unscientific data points.
