I had also read that DOW had the best grease, but had a hard time finding it. I am actually glad I couldnt get it as I believe the Haynes is the better option for this application.
Partially burned material aught to be partially decarbed. Stuff closer to your mouth isn't going to get hot enough.Hey Eskander.
Yes, almost painful. I can distill a liter in about 1.5hrs. Not as fast as a rotovap. But kicks the dog shit out of the ST.
Now that I have this still kinda figured out, I am somewhat regretting ordering a $3600 rotovap! It should be here by the end of next week. I might have been better off just buying a bigger still and cold trap. Use the rest of the loot on other equipment and supplies. I could have got a short path still as well. The money was an inheritance and not expected. So it doesnt hurt too bad.
With the Molykote, I first only applied it as you described. I couldnt get a seal so I plasterd it on. Still no seal but grease thin enough, it was getting pulled thru. The joints all felt seated. Discouraged, I left it for a few days to ponder. Then I had a 'duh' moment. You got other grease to try fuckstick! I tried the Haynes. Night and day difference in vacuum performance. And as you described, just a light coating.
Funny you mention the Sous Vibe. I was looking into that. A buddy had suggested it. I am still considering it. I will go with the Polyscience unit likely. It seems the most robust. Another option I was looking at is an actual lab unit. I have a J-Kem 210 Temp controller coming I got off ebay. Tired of being disappointed with cheap Chinese junk and deceitful listings. I got 2 different heating mantles off Amazon. Both garbage. The second one I got, actually had a brand name soI though it would be safe. NOT! Avoid Labasics.
I am presently distilling 1700mls of roach solution. This is the 2nd round. After the first distillation, it still grossly smelled like ass. So I poured it all back together. I added some fresh solvent and 2 heaping tablespoons of charcoal to it. Thru it in the freezer for another day and filtered thru Celite and charcoal once again. It actually smells not bad now. About 400mls to go.
EDIT: I am thinking I will raise the temp in still to just under 120C towards the end. Maybe I will get lucky and have fully decarbed oil. Maybe not. Its roaches so makes for a good experiment. But given it is roach material, would it not already be decarbed from the heat of the doobie?
I don't really understand all that your doing? but can I ask if you could clean it up with charcoal power? I've seen videos of people doing that? would it help or does it remove to much THC?So after decarb the was done, it was about 2/3rds black oil and 1/3rd solids that resembled asphalt when cooled. Far and away the worst looking shit I've ever made lol.. So obviously that needs some clean up. I redissolved in EtOH and filtered which got out this:

The white is the coarse filter paper on to of the DE cake. It usually doesn't do much for filtration but keeps the cake from being disturbed when pouring solutions into the funnel.
Still pretty funky shit so I did some small scale tests with hexane. The best result was 1:1:1 EtOH:Hexane:DI Water which is what SkunkPharm recommends. The hexane pulls everything lipid soluble out of the ethanol since once it is diluted to 50:50 it isn't nearly as good at dissolving canabanoids. The crud that ends up in the interface between the organic and aqueous layers aren't soluble in either but was soluble in EtOH.

Scaled up shaken thoroughly and left to settle for 12 hours (because the interface is slow to collapse outside a centrifuge) got me this:

I'm sure for all you RSO fans the black shit at the bottom here is what has all the magical properties. Certainly looks like something that would be great for you...

So that is still pitch black which I don't really care about in of itself, but since I'm just playing here I'm going to do a few Hexane/Saline washes and see if anything else comes out. I've saved some small samples of each step so I can run them on TLC. I'll update as I progress.

This actually went through charcoal once already. At the time I was unaware of quite how much canabanoid loss that would result in but MoeRed and literature suggest it is between 1 and 50% with the 1% guys typically coming from people selling carbon products. I'll run TLC on some before and after samples and see what I'm loosing. In any case, a lot of what I'm scrubbing out now would not come out in charcoal anyway. Initial extracts that come out green don't just have canabanoids, terpenes and chlorophyll, if they are green they have picked up plant sugars, proteins, waxes and other random pytochemicals too.I don't really understand all that your doing? but can I ask if you could clean it up with charcoal power?

There are things that can selectively remove most or all of some of those undesirables. Winterizing drops out the waxes. Hexane/Saline washes drops out sugars, protiens, some of the phytochemicals and because of the partial polarity of chlorophyll, it will slowly wash that out too. The first rinse with saline was so laden with random crap that the aqueous layer came out with the consistency of applesauce. This is kind of a pain in the ass and it does take a damn long time as the layers especially early on can take 12 hours or longer to fully separate but the results are are solid improvement in the extract quality with little loss of desirables. Once enough saline washes have been done to get as much crap out as you want, you need to distill or boil off the hexane and then thoroughly purge out the remaining hexane as it is toxic.
I'm mostly just playing around seeing if I can take the 5 pounds of low quality trim and refine something decent from it. The reality is that this amount of effort is in no way worth my time but it has been a fun to play with.

I'm no expert but I think it can remove oils? I do my QWISO then after I add 1/8 tsp to my QWISO then filter again through the Buckner, If it's still green I'll do the same again, Before I'm done I'll run clean ISO through the Buckner in a hope to recover any oil that the Charcoal is holding. I don't use any DE because I use the Buckner filter paper as the filter.@Eskander
I am a bit confused now. So using charcoal as a filter medium can actually result in a loss of THC? I have been mixing liberal amounts into the solution prior to winterization as well as a layer in Buchner Funnel in tandem with DE post winterization.
Could I be harming my extract?
Thanks for the reply Godfish.I'm no expert but I think it can remove oils?

I have very little experience with this and I'm reading like I have a test the next day, but from what I've seen DE is just an extra layer of filter? works like the filter paper, The Charcoal is what is removing color and taste. To be on the safe side, I use as little Charcoal as I can get away with to remove most of the green.Thanks for the reply Godfish.
I really hope it isnt a significant amount. Because as I said, I have been using liberal amounts. I wasnt concerned about charcoal wastage. I was more concerned with end result. Same as when I am using DE. So I really hope I havent been compromising THC/CBD content potential.
And as you said, I too run a rinse thru the Buchner with fresh solvent at same sub zero temp to reclaim residual. I am using a cereamic Buchner with filter paper and filter medium(s), not a fritted funnel. Is a fritted funnel better? DE scrubs as well does it not? That is why I have been using it.
So if you want bulletproof decarb after, boil off the solvent and then put the oil in one of these and put it in a pressure cooker and once at pressure cook it for 20min. 121C for 20min is a complete decarb. The only issue is that the off gassing of CO2 can pop the bag which limits how much can be put in each pouch. 25ml in the largest sized pouch seems to be about the right limit.Do you know if it's better to decarb before QWISO or decarb the oil after? I'm having lots of issues with the decarb after, Not knowing if I'm going long enough or to long, My thinking now is to just decarb before at 240/40.
I sure this question has been answered before, but because BRO Science and what I suspect "censoring" it's hard to find an answer? The best info I could find was from "Media Bros" <--- LOL more BRO Science? they say it will adsorb cannabinoids and terpenes. So it's better to use as little Charcoal as possible?I can test loss with charcoal on a fairly small scale by dissolving some extract in 2ml of ethanol and then dividing that, adding activated charcoal to one and shaking it for a bit then centrifuging both tubes down, purging both tubes on some preweighed parchment and then weighing them both. To be fair I need to wash the charcoal tube at least once to limit loss from adsorption and I might as well purge that separately so we can see if a meaningful amount is just in matrix. After that I'll TLC them side by side so we will have the mass difference as well as concentration difference.
If the charcoal is a perfectly selective filter then the total extract mass will drop while concentration of THC goes up and the mass of the THC in both stays the same. I don't expect that.

I just suck it into a syringe with a blunt needle. It is hot enough that it flows freely and is easy to collect from the corners of the bags. Depending on your use, you could just toss a ml of MCT in the bag after you get what you can directly and then collect what dissolves in the MCT too.Thanks for the tip on the pressure cooker bags, but at the amount I process (2oz every 2weeks) I'm not sure how to handle the small amount of goo in a bag?
Hello Eskander, have you been able to test the Charcoal?I can test loss with charcoal on a fairly small scale by dissolving some extract in 2ml of ethanol and then dividing that, adding activated charcoal to one and shaking it for a bit then centrifuging both tubes down, purging both tubes on some preweighed parchment and then weighing them both.

Lucky you, I've never gotten anything topical to work.Hello Eskander, have you been able to test the Charcoal?
I made some pain cream with trimmings and leafs, it works, I think?..

I played with it a bit after I had an accidental exposure that floored me. Dosing is hard to control and the effect is enduring so if you go over, you are on that train for a while. Decided it wasn't worth pursuing unless I had someone that couldn't smoke, vape or take an edible which seemed unlikely. Dosing a delicate area seems to speed it up but the first time I got hit it was handing a shitload of edibles without gloves on so it clearly will go through fairly thick skin. Bear in mind the effect was like an edible, there was no discernible localized effect.Lucky you, I've never gotten anything topical to work.
I used a paper shopping bag of leaf and trim, ground it all, ending up with 2000ml of plant matter, QWISO, distilled and decarbed it, added it to 237ml coco oil and 40g Bees wax, added Eucalyptus and Spearmint for smell.Lucky you, I've never gotten anything topical to work.
