SUGGESTIONS!?!
I have:
I saw @Apothecary36 ‘s post on hotter scrubbin’. Summit’s SOP says 42C…
Is there an obvious move here?
The Hotter scrub makes sense.
And the Summit is a Proprietary SOP for their carbon A…
not conflicting… but… Hmmm…

You can press it… it won’t hurt my feelers… too much… sniff
BUT IF YOU DO… post the secret sauce I’ma missing in exchange. Remember, one day YOU were a FNG… Yea, of course, not anymore… That’s not the point!
I’m always told that carbon works better with heat
Also, a carbon filtration usually removes the nasty darknesss from the etho washes. I don’t see that nasty darkness in the original post.
It seems like your color is not improving significantly. I would either try sub micron filtration (like .4 or .2 micron) and/or utilize the citric acid degumming. If your color is still dark after that then you can mail it to me and I will dispose of it properly for you 
I believe shadownaught said something about how carbon chemistry’s t-41 clay and mag/sil products are meant to be used in conjunction with one another.
IIRC the idea is that you don’t have to perform a degumming step if you use the acid activated t-41 because the acid in the t-41 reacts with the phospholipids in solution, the ph can then be readjusted back to neutral with mag/sil.
What is the difference between doing a cold or a warm scrub?
The way the oil and the adsorbent will interact…many factors are at play like what your oil is dissolved in…butane,ethanol,pentane etc. Also I noticed the ratio of solvent to oil plays a role…using more solvent to oil ratio will allow the adsorbent to be more effective
Wait, wait, wait ; what if you made it so that you have a little bit of activated charcoal inside a mixture that was inside a round bottom flask and had a 500ml fractional column on the flask and applied a vacuum with a cold trap regulating the vacuum @ room temp? Would.it help the a.c. Mix into the mixture?
Where would I obtain a filter that with that small of um?
Syringe filters are some of the best I’ve used, but I’ve only done it a handful of times when the clarity wasn’t as expected and I was overly paranoid about contaminants.
Be forewarned it is a long and painful process unless you have a good syringe as the filters get overloaded quickly.
Were the ones I used, I also got some chinese ones that worked equally well but took significantly longer to arrive. I would do research before just ordering something
Has anyone tried rigging these up to a vacuum manifold to do more than one at a time.
Any chance I can use this picture on my blog discussing distillate coloration?
I read t-5 isn’t bad.
Could get a sintered disk filter from hfs. They have stainless 0.5um disks
