08:37 – I’m making up chemicals and filling bottles for forensic science kits today. We have most of what we need to make up 60 more kits. As usual, I’ll put off making up Kastle-Meyer reagent until the last moment. We package it in glass, store it under an inert atmosphere, and refrigerate it until we prepare each kit for shipping, but making it up as late as possible extends shelf life. Actually, I’m not sure why I worry about it so much. I hold back examples of each batch, and periodically test them. I just tested one that I’d made up two years ago, and it still worked properly.
