Ahh that makes sense, if moisture stays with the butane. âŚ
This is all the used b80 u can see the chlorophyll it pulled and the clean cellite still at the bottomâŚand the spatula used to scrape fats out the wayâŚu can get these poly funnels of amazon for 15 bucks more sturdier than glass
@Intergalactic yes im running nitro p
But still going slow im running it from frozen tube into a 2x24 spool loose packed with t5 celite and silica getting crazy slow flow running 6 lbs material 30 lb solvent @Waxplug1 im running cryo pre filtered threw glass wool prior to filter media im switching to a 4 inch filter stack rig right now hoping fpr better flow product looks amazing just taking for ever
I can see my buchner warp on the bottom fritted part from the vacumn strenght when the fats blind itâŚif they blind it that much nitro pressure still wont be strong enough to push it through
Its surprising theres that much chlorophyll, i was under the impression that butane doesnt pull chlorophyll, are you doing any paper filtration prior to the buchner or?
No and youre right i could prevent some pick up but im doing it at the end either way
Like waxplug stated I believe itâs the waxâs binding? Are you dewaxing?
Hey whatever works for you, i lurk your IG shit looks fire always!
my material seems to be loaded with empty trichomb cells so im thinking about how to setup inline to prevent that from blinding the cake, and possibly catching some fats inline prior to hitting media, using a sleeved spool too keep it all coldâŚ
âAdsorbent scrubs are significantly more effective after the removal of phosphatidesâ
Yea thats why pass through cellite first
Yes running cryo dewax jacket sleeve with dry ice
What a highly interesting thread !
I see lots of experimental research been doing here. I love this.
I can bring some light from clay chemistry.
What you are basically playing with here is sorption of cations onto minerals.
Silica presents some charged sites, but much less âattractiveâ that clays can be.
It is a very good medium for chromatography, as everything will eventually get out of it (at a given rate) by just pulling clean solvent around.
â>This why some of you see green color getting out when reusing this medium.
Bentonites are another deal. They are mainly made of smectite (70-80%), and naturally contain a list of accessory minerals: quartz (=silica), feldspars, carbonates (calcite, dolomite), iron oxides (goethite, hematite ilmenite), sometimes pyrite, other clays and clay minerals⌠Smectite, more especially montmorillonite, is the active ingredient. This look like stacks of tiny platelets, with a layered structure, lots of interlayer space. It present a specific surface area and a cation exchange capacity (CEC) that are order of magnitude above the other minerals. This capacity comes from itâs permanent negative charge. Swarms of cations cover their surface, usually Na, Ca, Mg, and K (varies with their origin and history), which they can exchange with other cations from their environment, In ambient conditions, the exchangeable cations are hydrated. There is thus a kind of âstructural waterâ that is always associated to the clay (20% of total water on earth if I recall well). Usually it is about 7-15 wt.% of the bentonites.
â This is likely why some of you saw better performance and/or end product by drying or preconditioning their bentonite just prior to use.
In addition to their interlayers and basal sites, these minerals also present frayed edges sites, which are even stronger sorption sites, especially regarding metals. These sites consist in a set of oxygen and OH groups, from which the âpH of clayâ come from. They have a certain pH buffering capacity.
Cation exchange consist in replacing the cations sorbed onto the clay by others from the surrounding solution. It is a competitive process. It is a function of the relative affinities of given cations for a given sorption site, and of their concentrations in solution.
(in the following, this are only guess, as Iâm not really aware of plant pigments and industrial procedure behinds manufacturing of these materials and further use, neither of the behavior of smectites in other solvents than waterâŚ)
I think acid activated bentonite are industrially prepared by treated them with acid in order to desorb all metals adsorbed to their edges (the sorption capacity is lowered, and protons replace the occupied sites) on the one hand, removed the metal oxides, and also partly dissolve them in order to increase the number of frayed edge (so more active sites). In addition, they are treated with sodic solution to saturated their surface with Na (easier to re-exchange later for divalent cations). In some case, they are further conditioned back to a more natural pH (7-8) for specific applications.
Then I guess plant pigment are cations, and have a high affinity for clay edges, and also for basal surfaces and interlayers.
It is getting late know⌠I may better go a little bit out. 
I will come back with more details on clay behavior.
Definitely need a wider filter setup. I tried the tall skinny one a couple times and it didnât work well. I like how @Waxplug1 suggests using the celite to catch fats and the media beneath that and then the filters. It works well.
If itâs going slow, just let it happen. Itâll get there sooner or later. Just figure out what got you there and see how to remedy it for the next run
Thanks for the help im on round 2 using 4 inch filter plates like @Dred_pirate said way back giing faster but more color than tall and skinny but using less media
going to put celite on top tomorow
That first cellite pass makes a big difference
Two questionsâŚ
If we wanted to dry our butane would it be sufficient to pass it through a column of activated alumina? Any idea how much alumina to how much butane?
Second, if we did want to do this without a closed loop, which Iâm definitely not recommending, how would you recommend it?
Iâm concerned about violent evaporation and maintaining the integrity of the filter bed. Iâve seen a few posts now talking about manual filtration of butane solutions in a buchner talking about blasting into a container kept in dry ice, then youâd pour into another vacuum flask packed in dry ice, but what keeps the buchner and media cold enough? Would you simply pack dry ice all the way up to the edge of the buchner, effectively burying the flask from view under the dry ice?
Iâm interested in both questions for separate reasons, though the first question does technically apply to the second question in relation to preparing your butane for the next run.
Also, in the scam thread, terppin long ago mentioned using only carbon and celite to produce a clear product. Did anyone ever test that theory or did we all ultimately decide the carbonâs affinity for cannabinoids made it a poor choice when compared to bentonite clays?
This is what my buddy distilled for me from the fats i saved that got caught on top of that first cellite passâŚso basically im making crude and slabs at the same time
