Hi all,



I have 200g of ACRB, but for the first extraction, I used:

50g ACRB with Cyb's Hybrid Salt Tek, using lye and vm&p naphtha (kleanstrip).

After 12-18 hours freeze precip., here is the first pull, after pouring off nps.

Beautiful crystals, have a good time. =)

Dried

Lovely!

Bravo, bravo!
Those really look very nice. I hope they bring you somewhere unexpected

I get the excactly the same crystals !

I wonder why they sometimes split halfway along the center ! Btw congrats

Thats some beautiful white goodness. Love this tek, next time i want to try 'max ion tek'.

Thanks for the feedback!

I do seem to be growing an affection for the look, shape, and color of these crystals.

As a side note - I'm not really using heat baths or hot naphtha for pulls.

This was the next pull:

You really should combine all you're pulls to the one dish , it's so much more saturated but good result !!

Thanks for the advice, Earthwalker!

Question: What do you do with the initial pulls while they wait to have the other pulls added? In the freezer?

Remember that with this tek the pulls are about 45 mins apart.

So would it go like this? --->

1. Pull, put in collection dish, place in freezer.
2. 45 mins later, pull again, take dish out of freezer to add pull, put back in freezer.
3. Repeat


Is this what you mean?

Good job OP. I'm really impressed. Keep up the good basics man. That's way cleaner than my first pull.

That's one thing I stumbled upon, too. So how would you masters do it? Put the dish in and out or wait for the last pull and then put it in the freezer.

And generally, what will happen if you don't put the dish in the freezer and let the naphta evaporate at room temperature over let's say some days. The goodies won't evaporate - but will they form xtals or some kind of resin?

Take your pulls, one by one, and store them in a jam jar with the lid on. (either at room temperature OR in the fridge)
You can evap the end result down, to saturate the naphtha further. (if you don't mind wasting solvent)
Then Freeze

If you just Air Evap the naphtha, you will be left with crystals + whatever else is in the mix (oils, colouring NMT etc)

Freeze Precipitation results in the cleanest form of crystal.

OK, got it. Now it's crystal clear

wow. very jealous. great stuff.

Yes exactly what Cyb recommended ,when using ACRB I usually do 6 pulls back to back and store all the pulls in a larger drinking glass and use a glass coaster or lid of some kind and store them next to me on my extraction workbench at room temp
IMHO I don't see the point in refrigerating them then disturbing the cold naphtha which would be preciping extals just to add more naps and then removing from the fridge altogether just to pre evap or to do the mini AB ( defat ) , as follows , when all pulls are together !
I then get a 750ml glass bottle half fill with acidic water then place all my pulls in the acidic solution ph 2-4 shake like crazy at least 6-8 times let seperate fully pipette the old naphtha out and discard as it contains a lot off oils and plant fats and minuet bark dust particles , then add basic solution ph 12-14 the mix will go white strt away ( that's DMT ) add new solvent pull until all the white is gone usually 4 pulls then pre evap atleast half then freeze precipe as normal , end result pure white fluff as shown below !

Wow those are amazing looking collection dishes Earth...

Thanks to you and Cyb for clarifying that.

Now I see what you mean when you say you do a mini A/B on the naphtha. What's the difference in the yield when you don't do that step? Like if you just did what Cyb said and combined all pulls, pre-evapped, and then freeze precip, without the mini A/B? Oil/goo on the dish?

Only remaining question is - when pre-evapping to further saturate, about how long do you evap for? And under a fan?

My first 50g batch yielded somewhat less than I expected, about 650mg. But looking back it makes sense as I didn't adhere to the heat baths, and pulled whiter crystals.

Gonna give the another 50g a go over the weekend and probably include the mini A/B step - I'll definitely post results.

Cyb, it should make you feel awesome that you can provide this for people - thanks a million for teaching a man to fish.

Lets say you have 6 pulls at 50ml each...thats 300ml total...I would evap half that, down to 150ml..then freeze.
You can air evap (takes a while) or a cold fan (ventilated) over your jar (fairly quick) Just put a mark on the jar and stop when it hits the mark

You dont 'have' to do this (saving your solvent for re pulling after the freeze)...you could just freeze 100ml at a time in a flat dish (covered)
It really depends how saturated your pulls were.
The less volume in the freeze...the more likely it is to drop xtals.


Glad to help

Ok,

As instructed, 6 pulls of 50ml each were combined, then pre-evapped with a fan to approx. 150ml.

It took 5 hours to evap half the solvent, so I'd estimate about 30ml of naphtha is evaporated per hour with a fan blowing over it.

Spent 18 hours precipitating in the freezer -> poured off solvent -> put immediately in front of fan for 30 minutes - and now I have this:

Congrats Adjhart , looks like you yielded quite a good amount of crystals there

Well done , it is well worth the extra effort isn't it ?? You've got my vote !!
