96%; Like most people, slipped up with the Schlenk, thinking it was a Straus flask. Isn't the Straus actually a Schlenk Flask anyway, they are for the most part interchangable (Air sensitive reactions) and have the same structure. I didn't expect I'd do half as well as I did

I agree. A great site. I missed a couple that I should have gotten right.

I'd like to point out that Elemental does carry lots of glassware. Selling the Kjeldahl flask for only $20.

Here are pictures of additional glassware that we have in stock. We actually have a lot more, but these are the only pictures I have at this time.

I was about to say the same thing! Maybe in a year or so, a couple of us could drive over to your shop! That'd be fun! I'll be saving up! :)

Occasionally, I run across some glassware in my inventory that I don't recognize. Here are a couple of examples. I assume they are a type of manometer, but the stopcocks and the opening at the bottom of the "U" in the tube have me a bit confused. Anyone have a better explanation?

The opening at the bottom could just be a let-out for mercury (Manometers are filled with Hg, right...? sorry if I'm mistaken), and the stopcock a pressure release.

I got a 96%, but they have one graphic that is terrible, so it should not count. But I had to guess a few of them, but could elimate most answers, so not too hard. But it is an amusing test.


I got a 96% too. Correct me if I'm wrong, but I think the confusing part you're eluding to, and where I got my only one wrong, was trying to distinguish a Schlenk flask from a Straus flask. They looked almost identical. Furthermore, if you look up a Straus flask on Wikipedia, it doesn't have its own entry, but is mentioned - in the entry on Schlenk flasks!

I got an 80 but I also very sleepily said a beaker was an erlenmeyer.

I think I know the graphic your talking about. Those test tubes like images were really screwy. I'd never heard of a "boiling tube" before. Or a Strauss flask. Was fun though :)

73%

Wasn't sure what some of the particular round bottom flasks with extra necks and stopcocks were. I'm also not so familiar with some of the organic chemistry glassware. :(

However, I did get a good laugh at the 119 people who got 0-9% who apparently thought that flasks and beakers were the only glassware used in chemistry. :D

I got 66%.

One thing that is find strange is that when i only clicked the top answer i got 33%:P. Is it even possible to get 0-9 with random guessing?

It took one mouse click and passed thru two questions, twice, so no idea what they were.

Chem quizes like this are awesome, its fun to see what we all do and don't know. If all SM members enjoy these as much as I do, it might be worth doing another one through socrative or something. Socrative is just a website where someone can make and deliver a quiz to anyone who has a 'room number'.

I had a score of 83%. Not bad, given the fact that I do not have any formal education in chemistry besides my high school stuff. My profession is in software engineering and consultancy. I teached myself chemistry and also about different kinds of glassware.
