Best deal on bulk celite 545?

[Rowan]

Proof33 has celite 545 for $2.20/# shipped

Aghast at canna tax

Indeed I didn’t go in depth looking at that case #

[spdking]

Cass number doesn’t even matter. They are mis used in effect to only divulge the amorphous silica test result. Not really the on depth composition of materials. see certain types of silicas like process silicas are free and void of dust and unneeded particulate. Focused only on an engineered combination and mesh of silicas. Then there are organic ground pulled silica like DE. The issue is at typically those types and part numbers of a sea light 545 is much slower because of the salts and the dust and the powders and the unneeded unused combination of materials that are pulled out of the ground without being pre-processed. I’m a much bigger fan of pre-processed silica’s because they’re clean free from dust they flow faster and they’re more accurate

[Rowan]

Which silicas exactly do you like to use?

Are these types of DE good as filter aides?

Beaker liked the emd millipore stuff on Amazon

Where and what grade of Celite/DE do you guys use?

Celite 545 is definitely faster. Way faster in fact, so much so that it makes no sense to not use 545 as it pays for itself in reduced labor costs rather quickly. I can rough filter (20 microns) at 48L/hr with a Celite bed, with DE I was in the 15L/hr range, winterizing is even slower, so slow that I ended up pouring out of my filter and using a different filter aid.

I like engineered mesh silica.

[spdking]

No, bare organic silicas have dust and small useless particles in them. U want to have a combination of large particles and fine crystals but no dust and Clay’s or salts. Remember de by nature has organic decomposed sodium molecules in it from previous life, that’s diatoms.

cdlinc.ca sells it for $44.50CAD/50lb box

Maple syrup yo!

I’m using that but it’s so slow am I building my filters too thick? How thick do you go?

[Dred_pirate]

I use your celite stuff. It’s surprisingly not a bad price, at all. The disty guy uses it. And I use it to filter out fines.

[Dred_pirate]

I don’t use much, I just fill up the center of my retention ring and flush to the top of it. Not the plate, just the ring

[Rowan]

How big is the filter diameter

[Dred_pirate]

I use a 4 filter plate. Maybe 3" and ⅜ deep roughly.

[square_root_pharms]

Celite in my fritted glass buchner is about .5" thick it’s still slow after the first few mins

[spdking]

Btw proper silica blends never slow down. De and cheap celite will slow down. Silica that’s engineered typically doesn’t slow like that.

[square_root_pharms]

Could be it could also be carbon and bentonite clay the cake on top when they get filtered out

[square_root_pharms]

I think I might try y’alls powders out next

[Apothecary36]

Could you buy one of these cheaper bags and do a demo? So we can see the difference in speed

[Killa12345]

i would love to see a test. you let me know how much celite you would need to perform a test and i can donate it and send it to you on my dime.
