Re: [DIYbio] What are some good, hydrophobic solvents I can LEGALLY buy?

Maybe Simon or someone could weigh in on if this is easily DIYable,
but supercritical CO2 is a great Non-Polar (NP) solvent.

Depending on how edible/toxic you want the stuff to be (i.e. you're
adding it to some cells down the line vs just doing spectroscopy), I
know of quite a few easily obtainable solvents found at camping or
home repair (hardware) or automotive stores.

Gasoline, diesel, kerosene, ethanol, methanol, limonene (sold as 100%
citrus extract air freshener), Methy Ethyl Ketone, Acetone, Naptha,
Toluene, Xylene, Mineral Spirits, White Gas (camping), Brake Parts
Cleaner (acetone, toluene, methanol, CO2)
