And I guess I was trying to get at, if your not using cryo, you’re not getting almost all dewax
I say partial because most people here let me know that no dewaxing column will get all the wax out
Also I don’t if any terps are really like water… When it’s in the jar still and still have tons butane it looks really thin like water then, but after you pour, cap, then purge the terps that are left they are really really runny compared to the thick honey it would have been if you just purged down instead jarring
How much solvent did you recover? You want around a lbs of mother solution, when poured in a 24oz jar it be around the 350-400ml line roughly. Then cryo at that level.
Single solvent dewax will not remove all the waxes. You can confirm this by winterizing a small sample with etoh and watching for waxes to precipitate. You can cut down greatly on waxes being picked up, but can’t eliminate it with butane. I prefer to run good material cold and send it to the oven or a miner. I save the etoh for its own thing.
I remove up to an ounce in a 2 lbs system using a dual stage. Can’t image there is much more in there…and I never see any fat layer in my jars. Waxes really vary by strain, some have a ton some have minimal.
Dry Ice & Isopropanol should yield the same -78C as dry ice Acetone.
until I went looking for it, I was under the impression that Ethanol/Dry ice would also yield -78C. not so. There are at least a couple of sources putting it at -72C.
Are they talking about a pure ethol though, the water in the 91% most use cause any issues you think…
When I use denatured alcohol it stays thinner and seems to be able to handle more dry ice without freezing the alcohol up, but denatured stinks like holy hell…I imagine acetone does too
All else being equal I’d rather use iso than acetone in my cooling bath. if there were 15C in it, I might go with acetone. denatured 190 ethanol vs iso? I’ve always just used what was closest at hand. I’m not sure that 8C is a big enough temp difference to change that practice, but it might be…at least after I’ve confirmed it for myself.
Going to have to dig out my k-type thermocouples at take some measurements next time I get into the lab
too much? I wouldn’t say that. sufficient seems better.
I would also accept “more than enough” and have to admit that that sounds more like “too much” than “just right”.
just like any amount of ice in your glass of water should give 0C, any amount of dry ice in Acetone should yield -78C, until all the CO2 sublimes and is no longer absorbing heat by doing so.
