That’s the email I used and received the response from. Doesn’t sound like you guys can help unfortunately since the vials have no markings on them and vial caps are random colors but i do appreciate you responding, my bad for not following the opening procedures to figure out which vial was what.Better send me an email to tracy@sigmachemical.com.cn
my assistants can't help you that much.
I (Tracy in person) don't answer the sigma/whatsapp emails anymore, only customer service issues via tracy@sigmachemical.com.cn
Would be nice in the future if you guys put the identifying numbers on the styrofoam that holds the vials or on the vials themselves. But now that I know the proper opening procedure I won’t make the same mistakes again.
