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.

    Yeah this is why I always had a healthy fear of everything I was doing in chem class, I even missed an important lab day cause I was hungover and it was an HCL lab, shits scary
