In this video we discuss the Clevenger Apparatus, a useful type of Dean-Stark apparatus that can be used in both light return and heavy return modes.

The Clevengers are taking on their most difficult opponent yet: the supervillain known as Stopcock!!
I wish someone would make a comic book based on the names from chemistry. This week... Clevenger vs the deadly salt creep.
Underrated comment. 👍
Stopcock does the lab boy after having an oil bath. Only the cold finger saved the flat bottomed flask from beiing vacuumed to death.
Maybe it's time to study arsoles a bit more: https://en.wikipedia.org/wiki/Arsole
Hmmm... Any other apparatus you want me to go over? As long as it's not ludicrously expensive.
+NurdRage
spinning-band column lol ^^
24 kt gold vacuum jacketed variable reflux distillation head?
Seriously though, apart from condensers I think you covered the main important glassware for the amateur. Maybe column chromatography columns and the technique in general, although it is a ludicrously expensive method of separation for the amateur given the quantities of solvent needed. Or thin layer chromatography but its no really glassware.
Eventually I'm sure you'll get a rotary evaporator, and when you do you definitely should demonstrate it.
As someone who understands 10% of your videos.... I love the lab equipment vidsthe best and o don’t know why watching chemistry is so entertaining:)
There are a few absolutely essential and very cheap ones you’re missing: the NMR and the XRF spectrometers!
Its expensive but its cool: The Snyder column (for fractional distillation).
So, the clevenger has a stopcock, huh.... strange super-power
I would love to see you distill lavender oil
Archimedes, Newton, NurdRage !
Cody sent me.
They say that if you have lived a goodly life of strict lab safety you are rewarded by spending eternity talking about labware and with both nurdrage and nilered, each said to be cloaked in blinding white light.
I've also heard that if you're reckless you go to Utah where Cody makes you taste test various substances. There you will remain until you can correctly guess 4 in a row. No hints, no repeats.
Coloured liquids, multiple tubes of ~Stuff~.
Use of Science confirmed.
Nurd! Could you please do a quick video on how to measure the viscosity of fluids? I am in need of this knowledge and it's hard to find any quality content about it. :(
caramba LP using an Ostwald viscometer? There are plenty of write ups about it online.
what kind of fluids ? liquids/gases ? very viscous or not ?
poke hole in bottom of cup time how ling it takes to run out, compare to fluid of known viscosity.
I have been always wondering what the side tube was for , those glasswares are surprisingly cheap on Alibaba (range from $20-40)
Kain Yusanagi When you're working in a lab, where the safety of an entire staff, and potentially an entire building of college kids, are at stake, you've got to use high quality gear with traceability. A lab is a dangerous enough place to add another variability of safety. They don't price their gear for the person doing stuff in their garage. Also, the price that is visible to you and me is not the price that research institutions pay. They have separate accounts where they get discounts for buying 10-1000 units at a time.
Aussie Chemist I cannot believe that any serious chemist/researcher/professor would put their trust in some Chinesium garbage when the safety of other human beings is at stake...
Would it be easy to run a max P / max T / max delta test on budget glassware to get reasonable confidence in it?
I bought one, and what was delivered wasn't a Clevenger Apparatus.
They ripped you off?
"Almost impossible to understand" was a bit harsh... We've been watching your videos for years now
Shape is oddly reminiscent of a Thiele tube ^^ Literally never heard of this apparatus before you mentioned it. Thanks NurdRage!!
super hero porn star
"Sounds like a hero superstar". I had a weird, silly feeling about that name; I'm glad you managed to translate it into words...
"I will Clevenge you!!"
Thanks... now I know the name of that thing! ;)
I got one off ebay for very cheap. I don't remember the price, but it was below 50€. I bought it because I suspected to work as you described here from the pictures.
The name of this device makes me think when the inventor put this together someone in the lab said 'That's clever what do you call it?' but I'm easily amused.
I blow glass but have almost no chemistry background. it's great to see these running
Thank you for the apparatus series!
For some reason I feel like this is pronounced cleven-ger, instead if cle-venger
I love this video thank you for this I hope for more equipment videos too.
Does Illadelph make lab equipment too? Cause I love their scientific glass :P
I've always heard these called Dean-stark trap/apparatus
If this apparatus had a stopcock on the middle glass piece, it could operate as both a clevenger apparatus (when opened) and a dean-stark apparatus (when closed), right? That would be neat!
I doubt im the firat to think of that, so it probably exists.
That was freaking NEAT!!!
2:24 nice rig setup
Would it be a good idea to add another output on the side of the collecting tube, so that you can drain the light phase (continuously, even) without having to drain the heavy phase first?
I love discovering your videos early, late at night
Always remember folks, was this apparatus in an ice bath. Because Clevenge is a dish best serviced cold!
Groooooan. :*
More apparatus videos, please :)
I wonder if there is any version of this that enables you to use a Cow Adaptor to separate the phases - easier then switching out beakers
Damn I'm early
Ive seen these before but never saw it in use. I always thought it was a dean stark apparatus with a piece of glass in the middle for support... Didn't realize it wasn't solid, haha. Thanks!!
Can bismuth be retrieved from dyes, or the medicine using bismuth subsilicate?
Without buying to much equipment, what is the best join size to start standardizing with?
...I read the 24/40? Thanks!
nice that´s just perfect
Once upon a time i'd have rushed off to ebay to buy one.
good ol' deschem or ben0315 or someone will have them.
Very good! Some essential oils have higher SG than water - eg cassia oil (from Cinnamomum cassia , mainly used for cola flavours)
"Herbalist" 😜
I have a Layboy brand dean stark trap. :)
Is lab equipment like porn for chemists ?
Yes. I could go into more detail but this isn't the place. :?
How on earth do they make such complex pieces of glassware?
Really Nice!
It looks like it needs a second drain to the right just above the return to collect the light fraction.
The expensive models have that.
Dean Stark, better known as Glass Man, is the brother of Tony Stark, and a member of the team of superheroes known as the Clevengers.
i like these types of videos too
Ive seen other Youtubers put referral links to equipment they use in the video so that viewers can find it easily. Additionally the Youtuber gets a cut from any purchases made through the link. You ever consider doing that?
As soon as someone gives me a cut, sure.
can you make sodium methoxide from sodium oxide and cooled anhy.methanol? you can get Na2O by calcining Na2CO3.
please explain chittick apparatus for comparison of effervesent granules
NerdRage is Canadian confirmed! 2:00

Wait. Wait. Wait. You say "clevenger apparatus" makes you laugh because it sounds like a superhero porn star, yet you can say "stopcock" moments later without even a giggle. People, this is the difference between a serious chemist and an amateur porn star, I mean chemist.

You can get a peek of his condenser if you search Dr. N. Butyl Lithuim on pornhub.
