Source for C-18?

Looking for a steady good source of C18 silica. Other then @Shadownaught (called and they were out), any suggestions on suppliers from our gang out there?

I’m gonna start keeping a stock pile soon. I should starting in a week have at least 10kg on hand at all times. Just waiting for them to replenish stock. Once I gauge the interest. I’ll stock more.

I know your frustration as a lot of my clients are in the same spot. I’ll try to buy enough to put a little less strain on carbon chemistry. It’s something we have talked about me keeping stock of c18 as it’s getting more popular


I was talking to Dave at USA Labs today about it. I’d like to figure out how it’s made. Finally got a 6x48 glass fritter column that I’m converting to do DCVC with. Just need MORE C-18!!!

That shits more elusive then Bigfoot. Hate going the China route but do you have any experience with any from there?


What particle size do you need/use for your process?

If you approach any real scale then you will lose dramatic amounts of money…which can be remedied.
This type of t-remediation is like using a 500ml boiling flask to make distillate.
That actually may be too generous of an example. If you’re using c-18 it’s like selling green rso as the new thing.

Dcvc — also would be better to do positive pressure with pumps that won’t pulse.

I’m actually going to be doing a slight nitro push with the diaphragm pump to ensure consistent pressure/vac and having a three way air valve to control vac.

Nothing over 60 size

Is c18 the only functionalized sorbent thats useful for THC remediation?

No, but it is the most widely trusted for THC remediation

Send me your last quote. I have c18 typically and the lowest price.

im always $1500 kg shipped with insurance (as this aint cheap) anywhere in the lower 48! hopefully when i start buying mass quantities like other absorbents i sell we can knock that down a little.


That would be awesome! I think this is going to be my new pleasure. Between putting on the classes and consults, it’s going to be in high demand.

Do you sell personally or do you have a company you sell through?

Yes I have a company. C18 is not listed on my website but my company is

You will see me listed under carbon Chemistry distributors. It will be carbon chemistry c18. I just buy several tons of absorbents a month and able to pass that buying power on to my customers. That wasn’t a misprint either. Several metric tons a month.

I dont do that sent me your lowest invoice and ill beat thing either. I post up my lowest price for everyone to see. If someone can beat it…great! But i dont have a list price of $1750 and work down from there trying to milk every penny from the sale. I post a price im happy with the margin and thats it.


C-18 is now available at ChemChix Supply Co. :smiling_face_with_three_hearts: :partying_face:
