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?
The cost of a fresh beaker is worth mitigating the risk.
That could be argued, but where does it stop? New stir bars? New thermometer probe every time?
he's lucky to have a big enough channel to be able to afford 40000$ NMR machines, so a couple beakers aren't that much of an expense for much more safety
but as a home chemist, there is NO WAY I'm getting new beakers every time I wanna do edible chem, especially pyrex branded ones like Nile does. Lab equipment, even basic glassware, is ridiculously overpriced
Don't forget the phase-change cooling from the addition of solid state H20.
H2O, not H20.
No, they're talking about a ridiculously high mass isotope of Hydrogen. Turns out it has some wacky properties.
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
I see. I've only used ethanol for disinfection, and it was always methylated.
