Re: [DIYbio] Re: GoldBio VS. Sigma-Aldrich -- any thoughts?

 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.

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.

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??
