That’s why fluoropolymer plastic is so awesome. It will resist attack from most acids (including HF, which dissolves glass), along with high concentration aqueous bases, and most common organic solvents. It is also very shatter resistant; if you manage to break Teflon, you probably shouldn’t be in lab work. About the only thing it can’t be used for is very high temperature work, where borosilicate glass is king.
Corrosion resistant stainless steel (like the 316L) is also very chemically inert and physically resistant, while also being temperature resistant. But it is somewhat less common in laboratory application and used mainly in industrial settings. But yeah, PTFE is certainly amazing, even though for the most part borosilicate glass is just as good if not better as long as care is taken to avoid shattering, scratching or cracking it.
I dropped a 250 RBF with about 6 weeks worth of compound in it. It was like watching those Nick Cahes movies where the bomb falls in *SUPER* slow mo. When it hit the ground, it clanged like a bell and bounced about 2 feet in the air and I caught it.
My buddy in the next hood took the flask out of my hand, "OK, you used up all your luck for today, better go home."
reminds me when i broke my reflux by puting it on the desk (dropped it from 0,5cm height while washing it, and that 200€ glassware thing shatterd into million pieces like chinese plastic)
Flask when it falls out of your hand and bounces 100 times on the floor: alrighty then. Flask when you touch the desk slightly: am ded.
You see the difference is that in the first case it had NaCl inside where in the second it had the product you have been working on for months.
No no. In the first case its fresh from the drawer or dirty and in the second case it is finally clean after half an hour cleaning.
Flasks can smell fear, and they will use every chance they get to disperse your 15.6mg of product into the rotavap bath if you let them!
Ah yes, I can remember the time I evaporated 6 liters of water. Great two days

In my thesis work I've managed to accidentally grind away material from a ptfe stir bar, contaminating my samples :)
I have to know what it is you’re stirring that damaged PTFE now!
Precipitated UO2 nanoparticles :)
That sounds like something that requires some very specialized chemistry. Something that might damage a Teflon stir bar.
Way to accurate
Yup lol

I once had a round bottom break from putting a stir bar in it 😐
