Ok, thank you guys for this, I really appreciate it.
I just have one more question. It says that it is light sensitive... What does it actually mean?
I am shining light into my petri dish, containing LB + DNP (from microscope, in 5 ml, around 2h), is this damaging its stability, or induces some evaporation? I can work under dark environment, but then also until I weight it out and dilute it, it is not in the dark.
Sorry for such basic questions, but I need to make sure I do everything right.
