Surplus chemicals available (US only)

BeersLaw - 5-1-2023 at 13:29

Hi folks- I'm new to the forum, so let me know if I'm making all the rookie mistakes (please do, I welcome any feedback).

I am currently helping liquidate a failed R&D business. Most of the more valuable equipment is going through 3rd party resellers. But, I also have lots of glassware and some surplus chemicals. I haven't gotten much into the glassware yet, but wanted to offer access to the chemicals ASAP because we'll be arranging disposal on a fairly quick timeline.

These chemicals are, in most cases, already opened. (in fact many are years old). These were left in the company's chemical stock room (not requiring cold or inert atmosphere conditions). I have the inventory on the website below. I can't guarantee that the inventory is accurate or complete, but if there's something you can use, I encourage you to reach out with an inquiry.

If there's something you're interested in:
1) I will try to locate the item
2) let you know the approximate remaining quantity and observed condition
3) Verify that I can ship following DOT (and shipper's) guidelines for hazardous materials
4) I will ship (donate) for actual shipping costs (US only) plus a reasonable handling fee to cover the effort of arranging proper DOT packaging and shipping docs.

Regardless of what's listed on the inventory, I will only ship chemicals that are stable and don't form dangerous degradation byproducts over time.

Here's where you can find the inventory: https://sites.google.com/view/a-zlabequipment/home

Don't hesitate to make an inquiry for glassware and other lab supplies, I just haven't had a chance to go through everything yet.

Thanks!

It looks like there is some interest already, so I just wanted to add that i'll move as efficiently as i can, in the order of U2U messages received- and i'll update the chem list as things are claimed.

Thanks!

Hi-
My apologies, I guess I was premature when I offered the chemical inventory. It turns out that today the owner of the chemicals informed me that he doesn't want me to offer any of them. He's concerned about potential liability of providing chemicals of uncertain condition and unknown storage conditions. He's not a scientist, and just wants to avoid all potential circumstances associated with the chemicals.

My bad, thanks again for your interest.
-Andy

**admin- I don't see how to remove the original post. (sorry)

Are the other items likely to come up for sale?

Would I be out of line to ask what the R&D was researching? I see a curious trend of metal citrates and oxalates as well as a few selected alcohols. I’m just curious BTW. Would point out that suddenly it’s seems Etsy (at least in the US)has a respectable selection of lab chemicals which I find odd but interesting.
