cbd extractions?

i am currently looking into making a cbd concentrate. my preferred method is low heat bho with vac purge to finish. i have a batch of beautiful harlequin to work with. i am about to have the finished flowers tested to see what #s i have to work with.
has anyone run bho or iso specifically for cbs?
if so, how did it turn out? test results?
please be detailed with timing and temperatures used in method.
is this the same method used for extracting thc?

thanx for the help. i hope to learn alot

Is your CBS a typo and you mean CBD? If so, the same BHO extraction techniques will work for both THC and CBD.

I like 115F at -29.5" Hg if I am using the low heat method to preserve the extraction in carboxylic acid form.

I use 250F in air, if I want it decarboxylated as well as purged.

I pull substantially higher CBD concentrations from my normal level CBD flowers if i add a ~60min butane soak cycle to the process, research the "Thermos" method in this forum for simple directions...

Could you elaborate on what you are comparing the 60 minute extraction to brother P?
 
yes I did mean cbds. hahaha my bad.
I will look into the thermos method this evening. thanx for your help.

what are the differences in return of thc/cbd when u changed to the thermos method?
how is your terpene content with both methods?

I'm not doing anything arcane, GW - just a straight up comparison of the standard Tamisium practice of a single slow wash and adding in a soak (inversion) cycle to the process. Temperatures are kept ~freezing to minimize wax uptake in both cases, and reserve butane is maintained for a final rinse after the inversion.

In that case, I would have to say that adding an inversion cycle to a Lil Terp does the same thing. It takes more than a single wash to come close to getting what is there.

I pick up another 5% or 6% with a thermos over a column, unless I repack and make additional runs.

Both do a good job of extracting terpenes. Holding on to them during purge is where finesse is required.

Yes, the Lil Terp can do the exact same thing, and the Thermos should come close too. What would really be interesting, would be to use the TerpIII in comparative studies to see if the difference is more sensitive to solvent volume or soak period.

I'm also getting indications that there are other good things in the flower that extract more slowly than a straight tube shot can fully render, but research and testing are lagging behind my jollies...

I've had a few hundred hours running a Terpenator, and only a few running the Lil Terp. I primarily designed the Lil Terp to fill the ma and pa niche in the market, who can't afford a Tamisium and a Terpenator is gross overkill. It appeared to me that poorly ma and pa were being ignored, and taken advantage of by some of those who could afford expensive equipment.

I have more passive extraction development work scheduled, but more oriented toward what can be done on fresh frozen material, because David has videos out on how to extract dry material with a Tamisium passive extractor, and a Terpenator pretty much blows away a passive system in every other category.

The Lil Terp fits nicely in our chest freezer, which allows me to keep everything nicely cold throughout the process, while none of the Terpenators will.

I started the Mk I Terpenator at 10 cycles flood cycles and worked backward to find the sweetspot at 3 to 4 cycles for best return before diminshing returns and starting to take on an electric green hue.

The Mk's II and III all take about the same amount of cycles, so we usually call it good at that point, and average between 20 and 25% absolute amber return after winterizing.

We didn't have a GC when we ran those tests, so what I will do, is set up a Mk III Terpenator and analyze each flood cycle separately to see if the content changes as it progresses. The list of question grows, starting with what are the differences between what different solvents extract.

More on that after I've done and seen the results.

Yes, i believe low processing temperatures and quality materials are very important considerations in what you want to extract, as much as they matter later on in the purging process in determining what you retain in your extract.

As a passive system the Tamisium benefits in this regard because of it's excessive weight. It's not difficult to maintain a consistent temperature with such an effective conductor and heat sink.

You can afford questions with an in-house GC set-up! lol

I hope you can perform similar comparisons with the lil'Terp, as i suspect that there is a difference between washing and soaking...

sorry for the small hijack op

grey wolf?
what are you using for your carrier gas? and what column?

btw op, reads like you are near my neighborhood

More a question of affording time than inspiration brother Prune. I fall asleep dead tired every night and still don't come close to everything on the list. I don't move as fast or as far as I once did, even with my new biomechanics.

I will certainly make similar checks on the Lil Terp, and we have associates with Tamisiums, that I'm sure would be more than happy to participate. On the list.

After playing around a bit, we are using H2 carrier gas. We are using a FID detector and I will have to check to see which column our SRI 8610V came with.

It was purchased specifically for cannabis analysis, by Oregon Green Labs, whom I picked it up used from, when they closed their doors.

If you are in the neighborhood, do drop by for tea and crumpets!

haha, the neighborhood was to the op of this thread-near seattle

i'm guessing the column is a restek mxt-500 15meter, 0.53mm , o.15uf coating if it came already to roll
running h2 here also for convenience sake plus it's faster then helium

here's a link for a app that lets peaksimple export the chr and results to a pdf file instead of a hardcopy so it's easier to share. i like number 9... print2pdf and it's free/works good with win7

http://www.freewaregenius.com/the-best-freeware-virtual-pdf-printer-a-comparison/

may need to figure a way to exchange info instead of hijacking random threads :)

fwiw

Thanks for the link! I will definitely check it out and will pass it on to our resident software geek to implement.
 
thanx for the information all. gonna give a thermos type method a shot. a friend of mine does a hybrid method that is very similar.

just got my test results back on my harlequin. tested at nwba in seattle
8% cbd 4.25% thc. Really chocolate smell n sugary flavor
top 3 terpenes myrcene- 50.5% a-pinene 34.65% b-pinene 5.12%

not exactly sure what the terpene #s really mean yet. still looking into it.

not bad for first time with this flower in a brand new environment (not anywhere close to being a dialed in room, but it will be in a couple more weeks hahahaha I hope)
cant wait to try the extract!
I am very curious to see what the return and the flavor is like.
my friend uses N-tane, hmmmm haven't played with that one myself yet. but he swears it tastes better than the others

hit me up if u around here, we can dab n disc golf!
I like tea n crumpets too

Hey Man,

I'm in the Seattle area and work for another test lab. Would love to meet another IC'er and fellow dabber :)

If you've seen the Openvape and/or Sound CO2 around that's me!
 
sounds good to me! don't think I can pm yet. but would love to get together n dab....
how do we get in touch?
I gotta say the flav from this method is hard to beat......
the harlequin tasted like an amazing bouquet of flowers. my friend swears its petunias? never smelled or tasted petunias. so I cant deny or confirm such allegations. none the less its spectacular! super smooth smoke, light expansion on inhale, gentle initial high, about ten min for the kick in the face to occur. have to say I really don't feel any pain after a few dabs. cant wait to make more. too bad itll be a couple months
