    Or iso or MEK. I guess you need the Pepsi solvent dispenser for those.

    This image is a reference to things like this, where you send dry (containing low water content) solvent through a column of activated alumina to make it even more dry.

    It doesn’t really work as well with some solvents. The one I used in grad school had DCM, toluene, THF, and acetonitrile. If we needed dry DMSO, DMF, DMAc, acetone, MEK, or alcohols they had to come from a sealed bottle.

    Mmm THF. In another life I had a sample I was preparing using THF as a solvent, and I didn’t know how these tiny black specks got into it. Took a moment to realize the THF had dissolved the adhesive that held the numbers and markings on the glass pipette I used to draw it from the bottle 😅

    Oof, did you have to start over? What do you even put old thf in when you're done with it

    Yeah I had to start over or the synthesis would have been botched 😅

    Also we had to dispose of the bottle the THF came in, since the pipette graduations were now floating around in there.

    How did we dispose of it? Poured it all back into the bottle and labeled/kept it as waste.

    "The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. And I knew we’d get into that rotten stuff pretty soon. Probably at the next gas station. We had sampled almost everything else, and now— yes, it was time for a long snort of ether. And then do the next hundred miles in a horrible, slobbering sort of spastic stupor. The only way to keep alert on ether is to do up a lot of amyls—not all at once, but steadily, just enough to maintain the focus at ninety miles an hour through Barstow."

    We are closer to having McSoylent non-free-refill fountains.

    Many flavours, not just green.
    They all taste the and tho, but there is choice™.

    Where's phosphoric acid? That's the OG teeth solvent.

    The coca cola dispenser didn't even need to be edited. I've used that stuff as a solvent for engine block corrosion more times than I can count

    Ether would be good as gin and tonic, sub for tonic.
