Lab screw ups

My o-lab always reeked of acetone, i actually got nasues once or twice every lab and woulf take a break in the bathroom

Pro tip: she was aware you did nothing and would have felt bad if she mentioned how useless you were. In fact she probably ranted to her bf about how shitty her lab partner was and how she does all the work. I've been in that situation before (minus,the qt bf)

I used the wrong pipette and contaminated one of the stocks for the entire Orgo lab. I was the first one to get the solution, so everyone else after me ended up getting no reaction, and yet they never found out who contaminated the stock.

Oh come on it can't be that bad, aren't freezers insulated anyway? Did you like ruin a lot of rare samples or something? Surely they would have freezers like this with a dedicated un-unpluggable electrical supply, so i doubt a freshmans could fuck it up

Oh man! tell us again!

Nothing too major.

Dumped 8000 psi of air into a 2000 psi max pressure gauge because I grabbed the wrong dial. Tooted like a train whistle and fucked all the mechanisms up. $500 to replace.

Also I put a tray of rock plugs into the 100C oven instead of the 60C humidity oven, which dehydrated them and collapsed the clays, fucking the porosity.

Mining lab, btw.

I leaned on the emergency power switch and delayed an experiment by an hour. Not a big deal honestly.

Chlorosulfuric acid

Never again

I could buy the fume hood not working, but to have it vent into another room in the lab? Bullshit.

All the hoods would be connected to the same extract system, so if the whole system was down then vapours from one hood would diffuse into the ducts and down everywhere else, presumably.

Depends what the timescale was.

Physicists and chemicals seem to be a bad combination, I've heard of one lab where they needed to clean a lot of silicon wafers for surface functionalisation, so somebody decided to make up a nice big bottle of pirahna solution and then tightly stopper it and keep it for storage...
