  1. Ah, thank you all for your feedback. I'm probably just going to discard all of the bottles that were already open and hope this doesn't become an ongoing problem.
  2. Hello, I was trying to find information online about whether or not isopropyl alcohol has any fluorescent properties but haven't had much luck. From what I can tell, it seems not to. However, I have encountered an issue where I am using a fluorometer to measure aflatoxin levels and I noticed yesterday that all of my results were coming out unusually high. So today before I did some re-tests, I did a blank check of my solvents and my cleaning supplies, and the alcohol that I use for disinfecting (70% IPA) has been giving me pretty high readings. I find it hard to believe that the alcohol is actually contaminated with aflatoxins so I'm just wondering if there is something in the alcohol that is causing it to fluoresce or if I am just missing something here. Thanks!
