I consider glass to be the best option, but I probably felt differently a few months ago when I dropped a brand new vial of hCG and bac water.

Noticed that some of the research chemicals, even from the same vendor, come in glass while others come in plastic. Wondered if some of the solutions don't do well with plastic or whatever.

same here

i dont think plastic or glass make a differance to the chemical. Id go with plastic and store it in a cool dark place. Cant go wrong.
