Sad day dude.

I may well cry if/when i break one of my distillation rigs.
The glass work is Artful. Truly beautiful.

I can only say you should of checked the solvent compatibility charts that are online. http://www.wilkersoncorp.com/brochure/FRL-TEC-600.pdf it says pyridine is not compatible believe it or not :P:o
Im sorry that it happened though.

I just was doing something with potassium permaganate and I added an excess. After the reaction was done i doused it with water.... My whole concrete outside was purple. I got all of my hydrogen peroxide and made the pink go away. Then i realized that that just made manganese dioxide (even worse). I managed to scrape it up though.

I broke my last test tubes. Not a big deal, just really annoying.

Funny, I have way too many test tubes, but am at a lack of larger equipment and glassware. I had been given one of those beakers that has a glass tube sticking out of it's side for distilling and condensing (Can't remember the name), but dropped it when I was about 12 (2 years ago, when I knew almost nothing of chemistry). Pity, I had no use for it then, now I need one! :) Lab life...

It's not a big deal because I rarely use test tubes, I doubt it was Pyrex. I bought a 12 pack, and in three months, they have all broken from thermal shock.

A disaster happened in my lab today. I just had transferred my pyridine from my ground glass bottle to a 30 ml polycarbonate bottle. When I came back today after school, the bottle was non-existent and "luckily" for me, all the other bottles under it where made of polycarbonate... The bottles melted up.

About 20 of my reagents are too messed up to be recovered, mixed with melted polycarbonate, pyridine and other reagents that where aside of them...

That was a shitty day, at least I will know polycarbonate is a no-no for solvents...

I'm quite disappointed, I mean, it is like 300$ of chems destroyed... most of which that were very exotic, like vanadium pentoxide etc.


Damn, dude! Sorry to hear that. Must have smelled horrid.

Glass bottles only! With proper caps (teflon or polycone for boston round bottles). I always wrap the outside of the caps with electrical or metal tape for an extra seal.

Yes, at least I guess it smelled horrible. Better luck next time I guess.



I never asked for this.

That first link is SO funny :) Very specific needs. Side note: I accidentally sniffed some fuming sulfuric acid about a day ago. I know it's a big deal, but are the effects delayed more than 24 hours?

today, my organic extract was in an rbf on the rotovap, which fell off before I could pull a vacuum.

So I had to re-wash, etc.

But when I went to pour the contaminated organic layer in my sep funnel, the bottom was open.

Today was full of cursing.

the worst day ever


I was drying out Epsom Salt in a 2L flask with my heating mantle. I rigged up a glass tube to pump air into the flask, and it was drying nicely. I went upstairs to talk with my wife for a few minutes, which turned into an hour. When I came back the hard angles of the flask were glowing this weird deep red color. It was very strange to see black body radiation! The mantle melted the flask into the glass webbing. It was a super thick nice flask and the nichrome wire had come through the webbing and had become integrated with the bottom of the flask. Somehow it had melted into the glass and then hardened this way. I literally had to cry for a few minutes.

I feel the pain you feel I accidently let a solution of sulfuric acid and 2-napthol-sulfonate boil over and it completely destroyed a 300 dollar heating mantle, makes you sick doesn't it.

So, today was a pretty shitty day. My brother was helping me with a simple distillation, while I was away. Everything went fine... For a while. While he was gone, it somehow fell down and was completely destroyed - well both adaptors survived, but the condenser and both RBF's where goners. Luckily I didn't use a thermometer that time, because that would have been a big loss in it self. The whole day was a pisser to be honest.
While I was away, I was playing football with some friends, I generally go all out as that's my favorite sport. Anyway I dived at a bad pass to me, caught it with one hand, and used the other to brake my fall. I twisted it (my wrist) pretty bad. I don't give up easily (not for "minor" injuries,) so I continued playing after several minutes because I can catch quite well with one hand. It was my left wrist that I hurt, and I'm right handed, so I could pass it as well as usual. About 30 minutes later, I (stupidly) did nearly the same thing!:o Dived, and landed on my wrist. The only differences where, I didn't catch it, and I sprained it this time. So, my left arm is in a lot of pain, and close to useless.:mad: The day, went on with several more disappointments. All in all, Today sucked donkey balls. I guess it's not as bad as plante1999's Shit day.

I'm guessing it was ground glass? Sucks, man. That's at least $30 in replacement costs, assuming you make some damn good deals.

Yeah, ground glass. I'll buy a new one from Dr. Bob if he has any left. I don't want to buy another whole setup, since the adaptors are intact. They are 24/29, which isn't all that common, so my hopes aren't up about him having any, but I'll check.

Damn, that really sucks… The same thing almost happened to mine once. I stupidly left it outside and a big gust of wind knocked it over. Luckily I had other stuff on the table that prevented it from falling over completely. Nothing was broken.
