After spending almost a week now locked away reserching. swim has 1 kilo of powdered MHRB
But after reading thread after thread, forum after forum i still am a little hesitaant as to which to use as a solvent ... im thinking of hexane in tetrosyl panal wipe. has any one used tetrosyl before? was it clean, did it yield well?
Also what is the best tek for powdered MHRB using Hexane, with measurments of everything:grin:
Many Thanks In Advance

If yield is what your after, check out the BLAB tek, orange oil aka limonene is used. their are a few extra steps inolved in the extraction process, but well worth it, and bonus is that you will have fumarate for oral use.

ahhh the fresh citrus smell, yummy.

How about Heptane? according to some on here it is just as good as Hexane. i have just bought some and used it in cybs tek for the first couple of pulls. nice solid crystals. Here is the link, £6 for 2 litres delivered! evaps totally clean and is pure Heptane.

So, you can totally substitute Naphtha in Cyb's for that pure Heptane?

I was thinking I may have to do this but I am really too unclear on how to go about it, would you mind clarifying on how you managed it?

I warmed the Heptane, 50ml, and added it instead of the naphtha. I did this twice just as an experiment. The Heptane was then put in a pyrex dish and allowed to evaporate overnight. I scraped together the resulting crystals which were in the main very clean with a slightly yellow residue on the base of the dish. From two pulls i got 612mg using Cybs tek with 50g of MHRB. (I did another 4 pulls with naphtha and these are in the freezer.)

So just substitute the word Heptane for the word Naphtha in the tek and your good to go. I dont know if you can freeze precip Heptane hopefully someone will chime in with this info.

I will be doing Cybs tek again but this time i am going to use isoHexane and i will do all the pulls with this solvent. I will post some pics of this when i do this.

I have just finished re-exing the yeild from the two heptane pulls in 25ml of fresh heptane and ended up with 407mg of pure white crystal shards and a blob of yellow goo.:d

You answered your own question about re-x/freeze precip in heptane, but i'd like to chime in and say it works very well.

I've replaced naptha, with a limo/fasw acid base, then rebase and re-x with minimal hot heptane.

I've gotten ~1g of white crystals out of about 2.2 grams of heavily purified full spectrum fumarates from an limo/fasw acid base extraction on mhrb. You only need ~15-20ml of heptane when its near boiling hot (be careful obviously), to dissolve alot (i'd say about a gram) of dmt.

It will cloud when you blow across the top, or when its cooled. Do it in a glass container, preferable a weighing jar with a g/g top, or a shot glass with something to seal the top with.

Lots of crystals, and easy to recover. Then just evap until cloudy at room temp, and repeat until you have almost no heptane left. Evap that for yellowish waxy crystals that are just as good as the white stuff.

I love heptane, naptha & I never really got along much, and i didn't really get into freeze precips/re-x's until i picked up a quart of heptane.

Hi The day tripper,

i have never freeze precipitated Heptane, i have always evaped then re-ex. I do this by putting all the goods in hot Heptane then decanting the clean heptane into another shot glass leaving behind the yellow goo for later use. The clean heptane is then cling filmed and placed in a hot food flask to cool slowly. This results in very clean crystals which i recover by pouring off the heptane which i use again. I will post a couple of pics of my most successful crystal growing when i get home.

Ah me bollocks... ok just recieved tetrosyl panel wipe and did a msds search for the part number and now i have found that it looks to be naphtha not hexane here is an updated msds
Click to expand...

This is the tetrosyl panel wipe msds, date 2007.:
MSDS Tetrosyl Panel Wipe
Product numbers: NPW005, PWS025, PWS050, PWS201, THIN09, THIN10, MFS050, PWD005, PWD250
It says N-hexane, EC 203-777-6


So this one ^^^ is out dated, thanks for mentioning.
Your file is 2011, Product numbers: NPW005, PWD005, PWD250
Naphta, EC 265-151-9 <--- different product
I've tried to find more about EC 265-151-9 here:
a max boiling point of 60deg C, well that sounds not bad because hexane has a boiling point of 69 deg C, heptane 99 deg C. It looks even more volatile than hexane.
