Hello, I hope I have posted this in the correct place. I'm trying to post in extraction help so hopefully this is where it will end up. Firstly I'd like to say thanks to all the members and admins for making this one of the best places on the Internet. For the last few Months I have been successfully extracting using Cybs Salt and have been doing 100g extracts from MHRB and just doubling up on the salt/lye etc. I also make sure I have around 1.5 litres of water. I'm looking into buying a 2000ml erlenmeyer conical flask and was wondering if someone could kindly suggest any changes that I should make. Because this is a 2 litre flask I'm wondering if I would get away with doing a 150g extract and am trying to work out what volume of salt/vinegar de ironised water I would need and if it's viable. here is the link to the flask I'm looking at https://www.ebay.co.uk/i...:mW1cGoN0lBxZvwVPPF_XVtg I hope that this is not posted in the wrong place. Thanks in advance for any tips.

I am usually doing 200-250g MHRB extractions using A/B with salt. I am using filtered water (simply passed through a Brita filter).

This is what I do now:

- grind the shredded MHRB using electric coffee grinder
- weigh 200-250g MHRB in a tupperware box, cover with 600 ml water, mix well
- place in a hot bath (80 C) for a few hours
- freeze-thaw three times
- transfer soaked MHRB in a pot, add 600-800 ml water
- add some acid (glacial acetic, vinegar, ascorbic, citric, phosphoric - all these work fine) (this is optional, but maybe ascorbic acid or vit. C will prevent some oxidation; just keep pH around 4.0-4.5)
- heat up to 70 C while stirring (no need to cook!)
- cover with lid and let it sit for an hour or so
- strain to another (larger) pot through sieve (mine has approx 1-2 mm mesh) - the sieve should be fine enough to hold MHRB but large enough so the water is strained easily
- move MHRB from sieve back to pot, cover with 1 200 ml fresh water
- repeat twice (heat up, stir, infuse, strain)
- let the collected water extractions sit for 2 hours (so the sediment can settle)
- filter through wet cheese cloth folded twice (first decant the water, then add the sediment and help the water through with spoon, then add MHRB, close and squeeze the cheese cloth, discard MHRB which is now compact and dry)
- reduce the amount of water to 1 000 - 1 200 ml
- let the MRHB tea sit overnight (finer particles will settle)
- filter through loose cotton plug (vacuum filtration setup works best - avoid sintered funnel or paper filters as these will clog)
- heat the tea a bit, dissolve 80g salt in it
- add 50% sodium hydroxide solution by 5 ml steps with lots of mixing until pH reaches 12.5 (it usually takes 40-80 ml of the solution)
- transfer the basified tea to a container of choice (2L reagent bottle, 2L large Erlenmeyer flask, 2L separatory funnel)
- add 40-60 ml naphtha, gently tilt upside down and back for few minutes
- wait for emulsion to resolve, pipette/separate the naphtha layer
- put naphtha in a Pyrex dish
- evaporate 50-75% of the naphtha (until milky)
- heat up naphtha to dissolve micro-crystals
- leave the Pyrex dish at room temp. for 2 hours
- leave the dish in fridge for 4 hours
- leave the dish in freezer for 12 hours

Now I reuse the naphtha for next pull and heat up the tea to 40-45 degrees centigrade. I don't care about pulling plant oils as the extract usually goes to changa or get recrystallized in n-heptane to get crystals.

The filtering is not that necessary, it works fine even without any filtering and leaving all MHRB in the container. This obviously does not work for separatory funnel where you need filtered solution. Another advantage of filtering is having less trapped naphtha, less emulsion and one can magnetically stir the solution to resolve emulsion quicker.

Three or four pulls are usually enough to get almost all of the alkaloids out.

Wow thanks but I have tbh and say that this tek is a little too advanced for me! I'm just trying to jump from 100 to 150 using Cybs salt and looking for the correct amounts of salt/vinegar/filtered water etc. I know that I will be using 150 caustic and around 15ml water per g of mhrb and just trying to work out if the flask I'm looking at will be able to cope with the volume and extra salt etc. I've not tried the Max Ion tek yet with the freeze/thaw x3. I'm just keeping it pretty basic but would like to be able to extract from larger initial amounts of root bark. Nice one for your tek though bro. If I get a bit more confident in the future (and get a ph meter) it's certainly something I will try.

I would do a simple STB extraction with 150g of bark. First add the bark then fill it to the 1600ml line with water. Add 150g of sodium hydroxide and mix it up. After you mix add a little more water until you get to the 2000ml line then mix again. Don't use any heat and do a re-x at the end.  Cybs Salt tek is great for acacia but its not necessary with mimosa. All heat does is pull junk and by the time youre done cleaning it you basically end up with the same amount of dmt. I've done both STB and A/B salt extractons on mimosa and i get the best results with a simple S/B. If you're working with acacia its best to do a A/B salt extraction with a mini A/B at the end followed by a re-x. DMT extracting doesnt need to be complicating. If you listen to me you'll end up with pretty white DMT and be surprised by the results. Good luck

After you fill it to the 2000ml line let it sit for at least a hour. Add 50ml of naptha and mix for 60 seconds then allow it to separate. Once it separates mix 2 more times. Let it sit for a few hours after the last mix then pull. Do a total of 6 naptha pulls then freeze precipitate. Do a re-x at the end.

Thank you!
