Interesting thank you! What percentage of my t5 for the run would you recommend trying on the top of silica?
You need a 1/2" bed underneath your silica for it s filtration property so any thing more you use can go on top
Do I need that 1/2” even if I’m using celite on the bottom?
Well you probably don t but if you can you should silica is a tough powder to keep out in my experience and bentonite Clays once settled are great filtering media for particals

Sweet thanks for the help will post update tomorrow

My 2 pennies but if you add some extra filters it will fit tighter but a compression ring is extremely helpful. At the very minimum at the top.
Is your silica silica 60a?
What temps you running? The media works best when the solution is warmed
Yes 60a is what I’m using. Also I’ve just attached the crc on to the end of my column and it does get cold because I dewax my column with a slurrry. The weird thing is I was having great results doing the same exact thing with cold column just a different order I just think I was getting silica in there. I’m going to try and vacuum the stuff down today and just run a 1/2” of t5 under the silica and the rest on top.

Calcination is a process which uses high heat- often to bring about a specific morphology within a matrix. I have some experience making different sulfated metal-oxide catalysts and calcination was a necessary step to ensure the catalyst (more importantly, its active sites) were effective in facilitating the desired reaction

We just did another run. The color came out much lighter but is very red. We ran 4 lbs material and from 5 um sintered disk up a 2.5 um filter paper, inch of celite, 11um filter paper, 82 g of t5, then 82g of silica and 82g t5 and then 11 um filter paper. Does anyone have any recommendations to remove the red pigmentation?

Yes the CRC is inline at the bottom of column. You can kinda see it in the pic.
Poured a little out and the color looked good. I think it was just so thick in there that it looked red

Any specific strain or yust old biomass ?
Got me worried guys. We might to ban papers only
This needs serious attention by the powers that have the ability to check their stuff to verify

The opaque tranclucence gives me stress Place a drop in 3 drops of etho
And tell me if it s clear see treu after 30 minutes

Do you think powders slipped through? So just put one part oil to 3 parts ethanol?
Yes and leaf standing for a bit
Relax i am stressed easily 
Also we put a 2.5 micron filter after the sintered disc and it didn’t catch anything that I can see with the naked eye or rub off with my fingers. Not sure if that means anything. It really seems like we should invest in a microscope. Does anyone know what magnification we would need to get to see the silicate particles?
