Subject says it all. I know about Sigma-Aldrich, at $57 for 10 grams, and other vastly more expensive sources. Does anybody know of a source that
beats Sigma-Aldrich? From their reputation it shouldn't be that hard, but I can't find any other source aside from Alibaba.Dr.Bob - 16-3-2016 at 03:59
Strem sells it for $44/25g, a few others ar even cheaper. Search Google for both EGTA and the CAS number and there are many vendors.DistractionGrating - 16-3-2016 at 09:55
Thank you. I should have figured that out. I usually don't need help doing the Google.chemrox - 16-3-2016 at 17:26
Strem seems like an interesting source. I tried ordering from Acros and got referred to either Fisher - which died on the page or VW&R- no
thanks.. I don't like getting called on by reps. I worked for a company that had an account with VWR and they are too big and corporate for small
business. They do have good microscopes but the salesman tax is about 30%.

I don't think that's accurate. I work for a company with four people and we primarily order from VWR.Dr.Bob - 16-3-2016 at 18:28
Fisher owns Acros now, so that is not too surprising that they would refer you to them. And Alfa, Aeser, Avacado and Lancaster are all one big
company now, which I believe is also owned by Fisher now. So they and Aldrich (Aldrich, Sigma, Fluka, and a number of other companies that they have
bought out) control most of the market now.
Other smaller companies are Carolina Biologics, Oakwood, Matrix Scientific, Combiblocks, and ChemImpex. But most will still require some sort of
business or academic credentials to buy, but not all, so only for certain things. But many industrial and cleaning supply companies sell certain
chemicals as well. I know a few local ones as well as larger companies like Grainger and McMaster Carr. But if you search by CAS number and/or
name, you often will find the best sources. Names can be spelled many ways, often even hyphenation can mess up a search. CAS numbers work best
inside quotes, "12345-67-8" instead of 12345-67-8, which will often create a date or math problem.
