Hey there!
Silica Stock:
I have a pallet of silica up for grabs, slightly expired (03/16/24). There are 44 bags, 20kg each, and one’s got a tiny tear – consider it a bonus! Selling the entire pallet for just $10 a bag plus shipping.
B80 Batch:
Also, have three-quarters of a pallet of fresher B80. There are 27 bags, each weighing 25kg. Yours for $20 a bag, plus shipping.
Shoot me a message if you’re interested. I’m located in the Portland, OR area and pick up is available.
Is this similar quality powders to carbon chemistry ?
Yes, it is. I cannot be exact about the silica. It was purchased by a lab director before my time, and it was only used for a short period of time. I can tell you this for sure, though: it is ultrafine grain powder, and we never had any problems in our testing. I use some of it as a silica pack for Buchner funnels, and that worked out perfectly…
Do you have a coa for the silica?
I do not have a Certificate of Analysis (COA) for the silica, unfortunately. The previous lab director was not diligent with paperwork."
