Try doing a really short run, less than 30 minutes, at around 1100-1200psi, and 70-80F. I believe this will pull a nice terpene fraction that you can harvest, then after harvesting the terpenes, put your collection cup back onto the machine, and finish out a complete run at higher pressures and temps just to speed things up. Then, winterize your oil, and after winterizing, you can re-introduce your terpenes back into your oil. The terpene fraction may have some water, and lipids etc. in it, you will need a separatory funnel and maybe a small syringe to remove the water and lipids. I hope this helps a little!So i've been working with a Apeks 5000 20L. If i do my first run as low psi as possible on the extractor i get an oily substance coming out that looks like sludge. a light brown to a dark brown color. anything higher i start getting a mix of this and the crumbly waxy stuff. yesterday i had the first run sent to the lab for a terpene analysis as it's much more fragrant than the higher pressure stuff. how do i refine this first pull stuff? i'm going to try winterizing it and then using the rotovap once i get my cold trap setup as i've noticed i'm losing terpenes when i reclaim my ethanol.
please tell me you got this yield on a apeks 2000 5l........please. i get about half of that and i think I'm rocking it but if i could get that.....those chunks are huge i can't imagine those forming in a 5l but if they did i probably won't sleep until i figure it out.Subcritical...oil in one separator...dry wax/crumble in the other. But it's gonna depend on the CO2 system, not all systems are designed the same.
This is the most complete method of dewaxing and cleaning up extract available without a bunch of spendy gear. It is based on Dry Column Vacuum Chromatography but is deployed in a reverse phase configuration. I USE WATER TO DEWAX! lolHas anyone seen this being advertised? I have seen subcritical extracted CO2, which doesn't have waxes to begin with, but who has seen people able to separate waxes during the extraction? I know Graywolf has that waters machine, and can do it easy, but I wonder if other people understand how. I have also seen EVOlabs using chromatography to remove plant material. Ethanol dewaxing on a large scale is unrealistic. I know how...if anyone wants to discuss it I would love to.

By far the least expensive and conplete method to dewax without winterizing is by use of chromatography techniques. Fractional distillation is WAY out of reach of the vast manority of users, but anyone with a decent vacuum pump and some cheap gear from Amazon can dewax (and in fact fraction the product VERY easily with experience and a bit more effort than just the simple process shown.
60F is probably too cold, depending on what your separator pressure is... If you would like to run at 60F, you will need to lower your separator pressure, which can be achieved by changing your orifice to something smaller. The reason I say you need to lower separator pressure is because if you looked at a phase diagram, you'll see that the reason you created a puck of dry ice, is because you were more than likely creating solid, and/or liquid CO2 in your separators.
Or... if you would like to maintain high flow rates and not put a smaller orifice in your separator, you can just raise extractor temp up to 70-75F, this will maintain a good, high separator pressures which means high flow rates, and you'll still be able to get THCA build up on the walls of your separator. This THCA buildup is what is used for making glass like shatter. Keep in mind, if your plant material is not fresh, or has been decarbed you will NOT be able to make good glass like shatter. Shatter becomes hard, or crystalline, because of THCA's ability to crystallize, whereas THC will not crystallize. I would be happy to speak with you, or anyone else on the phone about this, and we can go into more depth.

I'm surprised no one has mentioned using a heated centrifuge. With one there's no need to winterize at all and it helps preserve the terpenes because they're not becoming separated and dissolved in the ethanol or any other solvent.
I have been searching for info on this method for the past few weeks and this is the first MJ related reference I could find for centrifugal separation. Are you using this method? Any chance you can share what centrifuge you're utilizing?
We are getting the new Apeks 20Lx2 duplex system very soon and I'm looking at any other dewaxing methods I can find. Thanks!
