distilled water, lab grade ethanol, a couple drops of limonene, and there you go
Sadly the Erlenmeyer flask was previously used for some nasty water soluble compounds and just looks clean.
rinse -> acetic acid -> rinse -> Acqua regia-> Rinse -> Pirahna solution -> Rinse -> 500°C oven -> Rinse
I would then drink from it without even worrying
Is NileRed then too cautious when he only uses fresh breakers for stuff he is going to eat?
Don’t forget the phase-change cooling from the addition of solid state H20.
lab grade ethanol
That’s usually methylated spirit. It probably won’t kill you, but you’ll lose your vision.
methylated spirits are the ones used for cleaning, lab grade ethanol needs to be just ethanol or some reactions might fail, however in some badly managed labs you might find mislabeled stuff and have contaminants
still, you shouldn’t drink it anyways, as some producers use the highly carcinogenic benzene to make pure 100% ethanol, as distillation with water can only get you up to the 95,6% azeotrope, and some benzene might make it’s way in the product
