Either way this works pretty good once you change some of the valves

I guess I should have given more information.
I clean my collection and other pieces on my CLS with ethanol. I am not big on scraping so there is substantial leavings in the ethanol
I winterize the ethanol and filter it. When I accumulate a couple of liters I distill it and with the oil that is left my GF processes it into different products such as topicals and tinctures and I get to reclaim the ethanol
I used to use a little extractcraft but it took a shit after 5 or 6 years of service. I picked up a 1 litre rotovap and to reclaim the ethonol and just like the extractcraft the left over oil is dark.
I started thinking about maybe filtering the ethanol before running it through the rotovap. Since I already have a buchner I have been watching videos and gathering up some things that might work
I am just playing around with this, and probably get more enjoyment out of tinkering around with stuff than most would understand
My plan, however misguided, was to pick up a fritted disc to place in the buchner, then a piece of filter psper, the make a bed of some media (probably celite) followed by some AC.
Like I said… for me the intrigue is in the journey, not really the destination
Thanks for the reply!

So it’s not about filtration.
It’s about color remediation.
It’s not misguided, simply not described worth a damn till this point, which made it harder to be helpful 
You are not using AC to filter ethanol.
You are using the butcher to filter the AC out of your tincture.
You would also be using that bed of diatomaceous earth in your buchner to filter out the ac (depth/3D filtration).
I assume you have read EHO Color Remediation
Edit: so when you say “buchner” are you actually referring to one of these?
Because the usalabs “buchner” is a perfectly usable filtration device, but it’s not a buchner. A buchner does not require the addition of a sintered disk.
Buchners, especially glass ones, may have a sintered frit, but if the don’t have one, adding one is not standard practice

Bingo!! I don’t have a buchner funnel I have what USA Labs “calls” a “buchner funnel”. I also don’t really speak the chem language properly or describe my intent and proposed procedure with anything even closing resembling someone who knows what he is doing.
I am closer to 70 than I am to 65 and my last formal instructions in the world of chemistry was in 1972. Needless to say in 1972 my daily activities usually revolved around purple oswley or a bit of white microdot. The only thing I really took away from that class was a D- that Mr. Dunham so generously gave me so that I would vacate the premises.
I love this stuff and I love playing around at a tinkers pace. I also appreciate your reply and then a bit of a concession that even though I don’t know enough to even explain what I want to ask (other than just wanting to know the micron ratings of "fine and “coarse”) That I am not 100% off track, you are for sure one of the exemplary individuals on this site that always comes around to lay down some knowledge to those in need… Thank You!!
The intrigue might be in the journey but the satisfaction is in the destination. Like the man said “Well, I don’t know but I’ve been told
You never slow down, you never grow old” Approaching 70 I take great comfort in those words
Thanks Again
