This video should be mandatory before taking organic chemistry in college. I would have greatly benefited from this video when I took my ochem 1 and 2 labs. The amount of glassware was so overwhelming and I would have preferred to learn what it was all for before stepping foot in the lab.

As a chemist, one of the first things you'll learn is that all lab technicians on duty are all named Igor.

8:07 That is not a dropping funnel... that is a Soxhlet extractor! A dropping funnel is used to add solvents or solutions to a apparatus. A Soxhlet extractor is used to continuously wash a solid material with a solvent to extract some solubile compond.

That was the shortest 16 minutes I've had in a very long time - thorough, interesting and absorbing.

Being a novice borosilicate glass blower, this should be interesting. I've been thinking about taking a couple of classes for technical glass ware. I like the idea of creating something with someone else that no one has ever seen before.

Great start in this outstanding series. I like the fact that i am so familiar with this topic since i prepare all kinds of dyes in my pathology lab

Hi Dave !! :D Awesome video !! These series is going to be amazing. One thing tho.... in 8:07 the glass were shown is not a Dropping Funnel, is the extraction part of a Soxhlet extractor.

Adaptors, capillaries, mass vials, TLC chamber are important too. Great work Prof. Dave

So cool to see this video's process from the beginning, when you first asked for viewers working in labs, to now :)

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.

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

Please do more videos like this! I just watched a few of NileBlue/NileRed's Chemistry videos the other day and was very fascinated to the point of wanting to order some chemistry supplies like the ones in this video lol. But this video was very helpful and brought back that same feeling. I love how you went through each item and methodically laid out what they were for and how they worked. Keep up the great work, my friend!

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

Great video! Will you cover the logic behind adding measurement errors?

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.

Handled most of this equipment many many times throughout the years.

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

I can remember from early A-level chemistry class being taught how to fold filter papers - from the simple double fold to the more intricate "fluted" arrangement (aka concertina folded), which helps when filtering a hot solution by minimising physical contact with the funnel and hence reduces the rate of heat loss. It occurred to me at the time that surely it would save time and effort if you could get filter papers which had been made this way in advance. Later that day, I discovered that you can indeed get those - just from the supermarket, where they are routinely sold as "coffee filters". Because of course doing a solvent extraction of ground coffee beans (which is essentially what automatic coffee makers do) also benefits from keeping the solution hot. So here's my question: Why are "pre-fluted" filter papers available in supermarkets, but not from lab supplies catalogues? Why are coffee drinkers afforded this convenience, while those doing practical chemistry have to make their own? It can't be down to expense, since coffee filters are dirt cheap, and lab filters are way more expensive. Anyone got any ideas?

You always make it easier and enjoyable 😉 ☺ 😊

your glassware model looks like he's having the best day

Excellent stuff, thanks!

Loving the custom made demonstration videos!

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

This really hit me in the "feels" and took me back to high school chemistry and college. For the young folks reading the comments: go to your labs! Seriously. GO TO YOUR LABS! Your companion laboratory curricula can actually be a lot of fun, make for a great way to meet people (especially as an undergrad when you'll be doing lab-partner oriented exercises), and your grade that semester is absolutely dependent on your academic performance AND your lab attendance. Undergrad lab work is just about showing up and learning the basics, folks, it's nothing to be intimidated about, I promise!

Wow, this took me back to myHigh School days. That was soooo long ago

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.

Im going into High School Sophomore Year Honors Chemistry so this is helping out a ton

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

Damn thought you had a coupon code for Thermo and I was stoked to use it at work when ordering reagents LOL

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

That's was very useful video!!

I almost failed in a lab exam when I overfilled the volumetric flask making the concentration of the solution low. This is very bad while doing titration experiments Somehow I calculated how much extra water I added , did the math and the titration(whose values was way beyond actual value) , calculated theoretically and reported those values

13:29 "Spectroscopy needs a container"". That joke will never get old.

Thanks 👍

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

8:57 totally agree

Now I kinda want a video on uncommon glassware.

8:06 This is not a dripping funnel with a pressure equalizing tube, but a Soxhlet extractor. You can recognize the Soxhlet extractor by the siphon on the side next to the glass tube for rising the solvent vapors. In addition, the ground glass joint at the upper end of the Soxhlet extractor is usually much larger than that of a dripping funnel. A Soxhlet extractor does not have a valve at the bottom, so it cannot be used as a dripping funnel. A chemist should already know the difference.

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

8:56 "fun to use" 😁

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

Rotovaps next please!

13:29 "spectroscopy needs a container" Flat earther dave: “I KNEW IT! 😡(buy my expensive stuff)”

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.

This is a really cool episode. I know nothing about chemistry but I like learning about new things.

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

I did a year of chemistry in college, before switching studies. Our student society, when having parties, had the option to drink beer from an erlenmeyer at a small discount. It was horrible to fill on the tap 😂

If you had a borohydride for example, it’s easier to use higher pressures and mechanical engineering, which is because of the low heat. Of course every lab is flexible, but personally you can’t stock up on glassware and expect everything to work. You will most likely encounter issues if it’s new.
