Cyb, thank you for this! I particularly appreciate the last two sections explaining the chemistry of how extractions work since my technical knowledge covers many areas, but not so much chemistry, yet.

Peace.

Cyb I don't see how you ever have any time to enjoy the fruits of your labor. Just one extraction tek after another.

Just finished with this extraction a few days ago myself. Worked great, got a nice yield!

Cyb you're a gentleman and a scholar, keep up the great work.

Currently using this tek on 125 grams of ACRB, will update once I have a yield, should be pulling tomorrow as I am in the freezing stage atm.

Cheers.

Wow, this is very well thought out and put together. Thanks a ton!

Just finished with this tek on 50g mhrb. Yielded a solid 1gram of nice white xtal after re-x.

Very nice tek, much kudos to you.
I'm not experienced with extractions but i will use this tek as a guidance in my first experiments with some ACRB and even if you say its for experienced extractors its very informative and detailed.
Something that would be very nice to know is when it is safe to take breaks in the procedure as it all cant be made in one go.
In some stages you don't want to let the mix stand for a longer period of time.
It´s a very well written tek with a much appreciated explanation section what is really happening chemically.
I will report back my results, starting with a small amount of ACRB, maybe 50 to 100 grams.

Very much thank you.

You can take a break at any time except when the naphtha is pulling.
Leaving it in the mix for a long time will pull a fair bit of yellowing.

Other than that, if it's your first time, I would try my first tek (in signature) to start.
The pictorial will explain further.

One more question.
I'm a novice at this so bear with me but i must ask, you say in the explanation section that the (optional) defat procedure should be done with the same solvent as the extraction.
Do you mean the same "type" of solvent or the same actual solvent used later but cleaned of the fats?
If same solvent, how you clean the fats out?
I guess you mean same "type" but i want to be sure.

Grower

Yes the same type.
If you use heptane for your pulls, use heptane for the defat...same goes if you use naphtha.
The small amount of naphtha from the defat is discarded as it will have pulled some un wanted oils from the acidic solution.

Very thanks.
You say i should check out the tek in the signature, that is the Cybs' Hybrid ATB 'Salt' Tek you are referring to?
I have not read it but doesnt an A/B with defat and salt work better for an Acacia Confusa powdered material?

Grower

It isn't an A/B...it's an ATB.
See Here
You can add in a quick defat with that tek if you wish. (It was designed with Mhrb)
With Acrb it may be advisable.

Very thanks.
I try with a small amount of ACRB powder first to see results.
I have a kilo and can obtain (edited as we don't talk of procuring here) more but i want to get my procedure working good and understanding it 100% before doing bigger experiments.
I'm also new to the effects but i am very experienced with shrooms and similar things so i have no doubt i will find this great.

Edit:
I have read about STB and A/B and i get all of how it works, but there is nothing like personal experince.
This i have learned from other experiments.
One can always be sure there is some stage of the procedure witch will cause doubts.
Emulsions are one, how to handle these?
I know to check the PH is right but other than that i dont know.
I guess i will have to handle all problems as they arise.
I have got some nice gear as 1l sep. funnel, a high quality hotplate/stirrer and vacum filtration equipment.

Grower

I the beginning one should put the material in an container and add 300-400ml of filtered water (i have powdered material).
Heat this for an hour, gently at not so high temps, 40-50 degrees C or?
When done and allowed to cool to room temp in the freezer it goes.
When its frozen you should thaw it.
Does "thaw" mean just let it melt or should i break the ice in a blender to speed up the melting or similar?
Then freeze again and thaw x 3.

Just curious about the definition of "thaw", it just says let melt.
Maybe its better to speed the process by crushing the ice and it might be good for breaking cell walls also.

Edit: I'm not of English language originally so i have little difficult with words as "Thaw".

Thaw (un freeze) to room temperature after the freeze, you can speed up the process with a heat bath. (refer to the pics for this)
Then freeze again etc.

Be careful if you have a glass container as stressing the glass with rapid temperature differentials can cause breakages.
Patience is key with this tek.

Thanx a lot.
No more questions.
I report my results.
Thanks for sharing your extensive knowledge, im so happy.

Cyb i have a question... how much distilled vinegar i have to add to a 50ml of ditiller water?

Really not sure how to answer that particular question lobo.
Care to expand?

In the tutorial you said:

"Transfer material to your glass extraction vessel and add a small amount of distilled vinegar OR ascorbic acid (vit C) OR citric acid to a minimal amount filtered water (approx 50ml) and the pour into the vessel."

This small amount... how much?

sorry but my english is not good enough...

Perhaps this sentence could have been constructed better...
It should mean 'add a small amount (approx 50ml) of vinegar (or other acid) to a minimal amount of water'...

Oh! now i understand !

Thanks Cyb, in a few days ill post the result...
