GoldBio VS. Sigma-Aldrich -- any thoughts?

[Ryan Hammond]

Hi all, I'm looking at some prices on the antibiotic rifampicin. SIGMA-ALDRICH sells it for $107.00 / g while I found another website I'd never heard of (Goldbio.com) that sells it for only $27.00 / g. That's a pretty significant difference in price -- anyone ever use goldbio.com or heard anything about the quality of their products??

GoldBio is legit. I buy odds and ends from them. Don't ever buy from Sigma. They'll sell ice to an eskimo and mark it up 800 fold.

I agree with Sebastian.

Goldbio is legit, I buy from them quite a bit, specifically for antibiotics. High quality, recommended.

Sigma is only good for chemicals or supplies you CANNOT find anywhere else.

 Under $16/g from Phytotech, but there's a larger minimum quantity.

The stuff from Sigma probably goes through more rigorous QA/QC, comes with a CofA and so forth.
