Common Scientific Glassware and the Undergraduate Chemistry Laboratory

Excellent stuff, thanks!

Thanks for the video Professor Dave.
I took chemistry a few years ago and this will help me remember everything again

What you call a Dropping funnel is actually a Soxhlet Extractor. It is used over a refluxing flask of solvent, and fitted with a condenser in order to extract a natural product that is placed in a paper thimble inside the extractor.

these tutorial videos are very usefull..thank you so much

Well done... I am missing my inorganic lab after seeing this video.

They used the watch glass instead of the paint trays because I'm dumb!

Some of my students probably used their hand instead of the mortar and postal for calcium bicarbonate because of my personality!

I hated the sep funnel as an undergrad and never taught it as a grad

The medical hemp bar looks like an e cigarette but it makes you stoned and sleepy. Pretty funny!

Man I wanted to show them vacuum filtration through the erlemneyer with the arm but Mike disabled all gas feed streams and vacuum stream out of the lab. Buckner yeah that's the word.

Some students broke a few test tubes.

I think most students prefer grad cylinder to beaker for volume of liquid measurements

1l beaker was the biggest my students had

I know it is summer break but what you need to know is that when I came back to school it was hard on me so I need to learn as much as possible.I thank God I passed my test but I will study. This video will help me a lot thank you sir

great, now i know the names of the pieces of equipment i need to set up my meth lab. you're the man, dave!

Werner Heisenberg is impressed.

Subscribed 😊 amazing video

isnt the dropping funnel a soxhlet extractor?
might look similar but are so different in use

Brings back memories of high school chemistry

The video presentation dude's stare is unnerving. 😰
Like brooo I'm not gonna nab anything stop staringggg

"It's just basic chemistry yo"

Who uses a separatory funnel as an addition funnel? That sounds weird!

Good

Excellent video! I am slowly building a small lab for fun and education.

Chili P

send jamal my love!! we love you jamal!!

I am teaching pharmaceutical chemistry to undergraduate pharmacy students in Kenya and I have found this video invaluable for introducing the students to the proper language of the chemistry lab and the purpose of each piece of equipment and glassware

I'm not saying Dave is wrong but i have never heard anyone pronounce Buchner like that.

And always use Pyrex glass

Sir !In which subject do you expert??
Can you explain curvilinear coordinates?

Nice channel

Good video Professor Dave. When are you going to do one about microscopes? That would be great

Actually a Soxhlet extractor is shown when you talk about a dropping funnel.

Well, we were taught what some of these were in middle/high school science. I'm used to a 'round-bottom flask" being called a Florentine Flask though.

Man that silly intro is always great 😂👌

Thanks 👍

I love the charisma of the guy showcasing the items, give him my complements

That's not a dropping funnel, it's the bottom half of a soxhlet extractor

U

You are so brilliant sheldon... however just stick with science and leave the philosophy

I love the way how you explain things...😊.can u plz make videos on laser

If you break the flask, then it becomes a face shredder. In all seriousness though, do wear your safety glasses because glass can get in your eyes when broken

Even though i have no affinity with this whatsoever, it was very easy to follow and interesting.
Great job 👍

Prof dave. Will there be video about characterization equipment in the future?

This is giving me a severe PSTD. While pursuing biochem, my labwork teacher forced me to memorize about a hundred different abreviations (with 0 logic to them) for various types of glassware, or she'd fail me. Anyway, in the end I somehow managed, but with couple more challenges like that down the line, I lost my passion for biochem and motivation to learn, and eventually dropped out of the university during the last year of study.

No such equipment on early earth, e? :P
