I carbon filter every run (with diatamacious earth), and I never see color change that drastic… are they using salesman tricks? Should I use more carbon? Should I grind mine fine like theirs? I use pellets right now, but I’ve got fiber flakes on the way…

If I recall correctly, Beaker no longer uses carbon isn’t that right sir? This is just the cryo solution through Celite 545 and nothing else.
The results you get from Carbon are going to depend on the ratios, residence & agitation time, and temperature. Carbon does adsorb Cans so it is important to tightly control time, temp, agitation, and ratios to limit the amount of loss.
First pic: pre carbon, 2nd: post carbon. Total loss was 15% by weight. Potency increased almost 5%.

If you look at how much carbon he added the ratio of filtrate to carbon is very high, probably 20+% carbon. That is crazy high and would result in a ton of loss. The loss is not a loss in volume rather a loss in mass due to the adsorption of desired compounds like terps and canns.
Additionally if the solution being scrubbed has a high concentration of chlorophyll and low concentration of Canns the color reduction is going to be dramatic. For example a cryogenic quick Ethanol was, which has very low concentrations of chlorophyll and other plant matter, will have less dramatic color reduction compared to a room temperature 10-20 min soak that has much higher concentrations of plant matter like chlorophyll.

I got rid of the green tint with a warm carbon scrub, then a vac assisted buchner filtration using a celite 545 cake on bottom.
Went from green to the exact color in the video.

Now, just my opinion, I did lose thc weight from the carbon scrub. Only tell I have is my finished extract weight from the starting material weight. Again just a guess.
Heres my thread you guys helped me with.

Good afternoon everyone,
This is my first real posting of any kind, so I hope I have chosen the appropriate place to ask my (hopefully not too silly) questions. Your patience is appreciated 
Our lab is trying charcoal and celite filtration for the first time. We are using a 2.5 micron filter in our funnel and I can still see evidence of celite and charcoal making it into my solution. How concerned should I be about this? I know I can likely get a finer filter and remove more, but do I need to? The solution will ultimately go through short path distillation. Will the trace filtering media cause problems with the distillation run, or will it simply end up in the tails with no problem?
Also, is it OK to conduct this filtration on the winterized tincture after the waxes have been filtered out? This seems like the most optimum time as the solution is not yet thick. I have tested on a small omount of winterized tincture, and the color changes alot! I know that is what it is supposed to do in general, but I want to ensure I am not just filtering out product.
Thanks in advance for all replies
Are you simply using a 2.5um filter paper/screen or are you using a 3D filtration media on top of that filter?
We are using the filter media on top of the 2.5 micron filter. We are doing this in a medium sized ceramic Buchner funnel.
charcoal
celite
filter paper
stacked like that
Hmm… Where are you sourcing your charcoal? Do you see carbon particles under microscope or are you just seeing it in solution after the filter?
I just checked my last fitration after cleaning everything up a bit. We don’t have a microsocope here at the moment. I don’t feel there is charcoal now (by eyeball), just some celite, so I have some improvement since my first post. I see what looks like a very small amount of celite. do I need to filter that out before short path?
Our charcoal is the best value vacs product shown in the video at the top of the thread
The celite should stop any and all fines from getting into your filtered product. Thats the job of celite 545.
How thick is your celite bed?
In my 600ml buchner funnel, i use a fitted disc, then 1" celite bed. Then IF i must do a color remediation, i use AC mixed in the ethanol wash and in the buchner funnel.

Thanks coppertop and Demontrich for the clarification!

We started using 500 ml glass Buchner funnel with fritted disk similar to your description. This works very well, so my original problem was I was just using the wrong equipment. No AC unless color remediation needed. We work with CO2 crude only so far so color has not been an issue.
Regarding the celite, how many filtrations do you perform before changing to a new celite layer? We are using to filter liters of material and changing to new layer when the ability of the vacuum pump to pull through the filter starts to diminish. Not sure if that’s correct. Maybe we should be changing more often.

I scrape the top layer of fines after every 2000ml filtered. Then top off new celite as needed.

I have been trying to use the celite 545 an ac to clean some Qwet an some bho but no matter what I do I always get cloudy oil after mixing with terps why is the ethanol oleoresin absorbing the DE? An how do I fix this?
I run bho then Winterize then I use bleachless coffee filters an a 6 micron qualitative as vase then make the de puck on that then do just like the bvv video but every time it’s cloudy after vac purge ? What’s up any help would be great
Hey, I’m a total newbie and just stumbled across this thread last night. Would you be able to message me or point me in the right direction for a step-by-step tutorial for this particular tek?
If you search my screen name, I’ve posted many times the ways of the “demon”. Plenty of pics to go as well.
