More apparatus and glassware videos plz! Hell, I'd watch one just going through all the types of condensers and their uses/advantages.
I recently got a clevenger apparatus. I'll probably make a video on it as soon as i can get over the name that sounds like a superhero pornstar.
Oo, kinky. Looking forward to it!
Right?! Glassware is probably deep down the whole reason I got interested in home science/chem. The solvents, unique reactions, and whatnot are just the perfect excuse to "play" with the glassware. :D
+tjbtech yes. so yes.
@NurdRage I feel like I've watched that anime before...
Been awhile since i last did a lab equipment video. As for the topic: I admit, i didn't fully understand the concept for many years. I'm pretty sure i still don't fully understand it even now.
Anyway, my sodium silicate video had some errors in it so i took it down and i'll reupload in a few days once i fix it.
NurdRage No notification.
I don't understand it either, when I see "distillation", I think of Whisky... :P

do you have the bell turned on?
Maybe next time you'll talk about fume hoods, heating mantles and burettes... Hint Hint
Degradation, and decomposition is something I would've brought up too. @nurdrage check my insta: @thaorganicmechanic
Make more videos on lab equipment please, these are so thorough. I actually just got one of these in a box of assorted glassware. The box had about 32 pieces of glassware for $25, best deal I have ever found. I already knew what it was because I watched this video a year ago. Thank you for your content!
Always great to see an equipment/technique video! It helps a ton for amateurs just starting off in chemistry.
Am I the only one who love the word "apparatus"? Whenever I hear it, it just sound like plain science. :)
Caught you on VICE! Nice work man. Power to the people!
A 14 jointed short path distillation apparatus was always permanently in my syringe tray in the oven during my PhD. It's really convenient when you want to quickly purify a couple of ml of reagent for finicky reactions. The true significance of the "short path" never occurred to me! We would invariably use a kugelröhr for sensitive high-boiling compounds.
Thanks for the videos. They're very informative!
I had no idea about the advanced function.... Glad i watched this!
Wonderful! I sometimes thought about evaporation as a distilling technique but then I thought "meh, if I haven't heard anything about it, it means that it can't be done".
Also, I thought that there wasn't a real need for it since there is vapor current distillation.
Nice to know that I was wrong, you learn lew things everyday.
Well explained about Distillation of essential oils and solvents recovery. Short path distillation widely used in determination of boiling point of mixtures also recovery . Very nice explanation given .
Awesome ! I bought one of these a year ago because it was cheap. Never really knew what to use it for - until now !
thanks.
I saw one on my old workplace and never figured out why it was special until almost ten years later. It's one of those subtle things you almost never think about until someone tells you.
Best thing i can say about it so far (never having used it) is that it's small enough not to get in the way ;)
According my experience this accounts for most special lab glassware. If I have a look in our lab I'll encounter quite a lot of deviating glassware pieces, most of it was custom designed for a special purpose. When the project is finished and the experimenter gone, hardly anyone remembers whats its exact purpose was :-) An experienced lab worker can reason what its purpose is but e.g. at most Uni's people come and go and so does its practical knowledge.
Some method of pumping gently the vapour and residual gas might help quite a lot. Perhaps putting on a stirrer might have great benefit, as it also agitates the gas. Flowing a tiny bit of gas to near the surface through the thermometer hole may also work.
I love your videos about lab equipment
Thanks for making videos!
Cool, I once came across a dealer that sells it, originally I thought it’s for extreme small scale reaction....
Im a glassblower, but havnt worked the torch in a couple years. This makes me wanna get back at it and make some lab toys
beautiful piece of glassware. That must have taken a decent bit of work.
I did not receive a notification even though I have clicked the bell icon and gotten notifications on all NurdRage videos before this one since I clicked it...
Thanks for the lesson! I've an idea kicking around in my head for awhile that basically amounts to distillation at sub-boiling temperatures, but wasn't sure if it was possible, or if it would accomplish what I had in mind.
Pointing out the benefits of a short path, and using vacuum to increase the mean free path (if that's the right term) for the molecules we want to distill, gives me a much better idea of how I might set up some experiments.
research: "film distillation", "film evaporation" and "molecular distillation". There is advanced equipment out there that takes this concept to the extreme. They're expensive though, so i'll never be able to afford one for my videos. But they're out there.
NurdRage Thanks! I'll look into it. I have found that ebay can be a good source for deals on equipment. Unusual stuff and truly good deals take a ton of time and some luck to find - it's not a big market - but I have gotten some embarrassingly good deals on expensive glassware. I can keep an eye out if there's anything you'd like to find.
I wish I knew about this a few years ago for solvent removal with a very temperature sensitive product.
cool bong my man
dude inhaling combustion products is so 2001..
﴾ ﴿ Water pipes can be used with vapor. That’s mainly what dab rig style bongs are. As well as convection style vapor generators with water whips, etc,.
Cool Hand Luke that's what I thought to
Well that was neat as neat gets!
you can also use 2neck flask and introduce inert gas flow to speed up evaporation
Superb
Don't forgot it's also used for the production of high purity acid. I routinely do this to produce trace metal quality HF, HNO3, etc, for total digestions; naturally, this is done in PTFE in place of glass. Saves ALOT of money when compared to buying the acids outright!
We used short-path distillation when purifying dithiothreitol (DTT) under vacuum.
I would love to see a video on essential oils. I have been trying to find out how they extract aroma from coconut but I couldn't find anything. Maybe some aromas can't be extracted? Also can essential oils be used in chemistry to make desired compounds?
Some "essential oils" are made synthetically. They synthesize key molecules and mix them up. For real essential oil extraction people usually use steam distillation or a water/alcohol mixture
Cool :) I know NurdRage mention that the Short Part Distillation Apparatus could be used for essential oils. So when is it better to use this one over steam distillation? I feel the whole world with aroma and perfume is kind of hidden and you can't really find that much DIY videos about it. Could the coconut aroma be extractable as an essential oil? How do you separate coconut oil from the essential oil?
@@nattsurfaren i'm not chemist but i've been playing with a spd for a few days and I discovered that some terpenes have low boiling point, like 40°C... so If you catch all vapors, you may get water+oils and then can separate easily by freezing. cheers
Did you know the coconut Terpene is believe is actually mango🥭
Nice kit. I really want one for home remedies
We can provide complete short path distillation with vacuum pump and chiller.Just send us an inquiry.kedayq.en.made-in-china.com/product/oNSmWOcGnlVx/China-Portable-Short-Path-Distillation-for-Cbd-Oil-Extraction.html
Thanks
And I never knew such a thing existed. Now I know what to use when my traditional distillation apparatus doesn't perform as desired.
In the future could you do a "lab equipment" series video on vacuum pumps? I'd like to own one but haven't yet purchased one because I'm uncertain about the complete setup. I've read that solvent traps are supposed to be used to keep the vacuum pump safe, but I've never seen someone break down their entire vacuum setup so I don't know if additional equipment besides just the pump and tubing are required.
Nice!!!
Diffusion... or an aquarium pump circulating the air in the system. Think of it as a solar still with a blower.
The pump can pull from the vacuum port on the short path still, and bubble into the boiling flask via a tee and diptube. The circulating air (or other gas) can carry plenty of vapor well below the boiling point.
Very cool.
Dead ass looks like the most dope bong downstem ever.
I went thru almost the whole video wondering why you weren't saying to tilt the boiling (vaporizing?) flask. Finally you mention it at the end... :-) I'm gonna guess that you intend this for use with tertiary alcohols. Does this mean you have some more of that action in mind?
Dammit! I alredy have a need for one, but all of my Uni's glassblowers are in vacation for at least two weeks!
Nice .
yes
Yay 😍
No way! I used that apparatus today in the organic lab course! I was very afraid of breaking it because it's the most expensive piece of glass in our lab to break, about 300€ ! :D
what were you distilling?
I was separating three unknown organic substances apart that was part of our course. One was amine, one was neutral solid and third was neutral liquid. I got the amine distilled with short path distillation apparatus under vacuum. 63C/12,4mbar. A few drops was all I got. Now I'm trying to determine what that substance is.
amazing! i wish you all the best in your analysis.
Thank you! Scratching my head with IR spectrum right now. :D Seems to have an aromatic ring at least...
I like how you pronounce "sodium hydroxide".
Sounds ideal for concentrating peroxide.
Nuovoswiss well that's what I was banking on, hook up the vacuum adapter so there's less risk of decomposing the peroxide by heating.
I know I didn't word or explain my thoughts well enough to indicate that I would only want to remove the water, and not distill it off for collection. I was looking to shorten the drying time into hours instead weeks through passive evaporation. If that makes sense.
I'm really curious to know if you can use alcohol and dry ice to run through the condenser or would this be too cold and cause more issues I'm a little nervous to try it myself but I'm curious if it would work in some situations never seen anyone do it
We have the same extension clamps
I have one question for you, In the potassium chlorate video you made you said that you were going to make a more efficient cell, is this something you still plan to do? Thanks
It's called "short path" because it is possible to have a mean free path that is considered short (i.e will collide with the vessel before another molecule). Having said that it is almost impossible for that to happen in a short path head. In fact you'll notice the vigreux on the column section and this clearly indicates that there is some vapor interplay. That's ok though because it is a great tool for separation of high boiling point materials. The column section provides more separation capabilities than a true short path.
Is short path distillation viable for azeotropic distillation?
Because given that you use it at lower temperatures, how would you determine what azeotrope is condensing over?
Is there a way to jerry rig a condenser at home? Maybe a glass tube inside a bigger plastic pipe would work. The difficult part is to connect it to the apparatus.
This is by far the most informative distillation video I’ve ever seen and I’m on almost daily searching and watching videos. Much respect!! I’m going to hit you up soon. I’m jay @cannabis_miamor. So happy I found you
Can you do a video on “piranha” acid? I know it’s basic chemistry but it seems as though it’s less widely known for its ferocious appetite. I’m curious to see just what it will eat up
It'll eat pretty much anything with carbon in it.
If I try elimination ethanol of one extract with a low temperature I will break my pump?
I wanna make it because I don't wanna buy a rotary evaporator too. It's so much expensive.
A pretty common set up among cannabinoid distillers.
Go on...
Seems like you could extend/lengthen the condenser section if you wanted
what is the lowest temperature you can distill water with all of your equipment
You can distill at almost any temperature. I.e. 5 deg C at atmospheric pressure. It will be just very slow. You can make it work maybe one or two degree below melting point, but this requires rather extreme pressure conditions. Not available in most of the labs.
unable find apparatus you show us at the glassware link.
who proof-views these vid's pre-release for completeness ?
I always thought that it was only useful for distilling things under such a vacuum that boiling point and melting point come very close, so that you can use cool enough water to condense it, but don't give it enough time to freeze. When I distilled phenol under vacuum with a regular Liebig condenser, I had to keep my water at 50C to avoid freezing, but 50C cooling water is quite inefficient when your compound boils at below 70C...
whats the rough surface on the glass near the entry? is it an ice holder?
Would one be able to distill sulfuric acid using this setup?
Molecular distillation made easy :)
Can you give an example of when you would NEED short path distillation and steam distillation wouldn’t be sufficient? I know steam distillation requires the product to be immiscible with water, but it seems like there should always be at least one low boiling solvent that is immiscible with the product.
Would this be good for destilling sulfuric acid?
number 7!
Can a carrier gas be added to help flush vapor to the condenser? A slow flow of argon into the distilling flask while pulling vacuum on the collection flask or similar?
unreasonablescissors I'm thinking very slow flow a few tens of mL per minute
Man can you help me. I have a distillation set up with a 10/30 thermometer slot in the top. I want to use a thermocouple in a well adapter but am not sure what part to search for. Can you help. This has grounded me for the moment.
Do you happen to have a video on the cow bell receiver? It's a turn to make your cuts kind of situation not each component will automatically separate out into each flask right? 😂
Would this be a viable option for concentrating hydrogen peroxide?
I am still waiting on someone to do a more involved video of the one ChemPlayer started, producing nitrogen tetroxide. This time, without nitric acid. :-\
I have a question. Can pure H2 gas be used as a catalyst?
Can you make a video on how to extract ammonia from fish tank water to use it in chemical reactions
It can also be used for making phenol . It tends to crystallize and you need to shortest possible path possible in actually pump hot water through the condenser to keep it from packing salad with phenol crystal. I've never tried to do it with vacuum however vacuum would probably mess it up pretty badly.
I ended up moving before I was able to do the phenolic plastic experiment that I wanted to so I got a boiling flask full of the crystal sealed in three bags somewhere. I've moved twice since then. The chick kind of scares me
I'm an electrical engineer and I've been watching your channel for a long time because I love the science, but lets be real here man... That shit is for weed.
Would this work for CBD/ THC extraction never seen it on a small scale? Had privlage to see the roots sciences thin film and have used a 5 litre mantle with a much larger head. This would be awsome.
We are a Chinese manufacturer of short path distillation,2~20L,and ancillary equipment vacuu pump and cooling chiller.Just send an inquiry.kedayq.en.made-in-china.com/product/nCgENLovhWkx/China-2L-5L-10L-20L-Portable-Cbd-Oil-Extraction-Short-Path-Distillation.html
would a rotavap be comparable (but more expansive and bulky overall) since you can heat bellow the boiling point under vaccum then consense in another flask
Barnesrino Kripperino a roto is much more efficient and if you have to reclaim a lot of solvent, a short path is not appropriate
is there a evaporation point like boiling point ?
Neat! I'd never really realized that evaporation-based distillation was something that could be done, though I suppose it's kind of obvious in hindsight. Would it be possible to speed up a distillation like that by continuously pumping some gas into the flask to push the evaporated molecules through?
There is actually a super advanced version that uses a rolling film. Basically you carefully drip the liquid down one side of the apparatus and it evaporates but it immediately condenses on the other side of the apparatus which is cold. The distances between the two sides is just a few centimeters. No need for pumping or gas pushing.
But that piece of equipment is highly advanced and costs many thousands of dollars. I'll probably never be able to get my hands on one.
Na
Yep! It exists! It's called vapor current distillation. You boil water in a separate flask, and then the vapor passes in the distilling flask with your compound(s) in it.
The water vapor pushes with itself minuscule droplets of the high-boiling compound.
Beginner here - Is this a suitable setup for ethanol recovery from a crude oil?
All the percolation! MasterBong here lol
I do this all the time with acid such as HNO3, HCl, and HF. We have a different system for the HF and the other acids, but it's always some sort of short path low temp distillation. Our lab made system is also 100% teflon because of the HF requirements. One last thing is that our distillation systems are typically 100% sealed off from the rest of the world. In other words, not atmospheric.
Does this work for eg sulfuric acid?
Diffusion... or an aquarium pump circulating the air in the system. Think of it as a solar still with a blower.
What is Distillation Cow Receiver used for?
Thanks in advance!
That's used for fractional vacuum distillation. If you're running a vacuum distillation that will have multiple fractions, you will need to switch to a different receiver flask as the new fractions come over. A cow receiver lets you rotate to a new flask without having to stop the vacuum and disconnect/reconnect a new one.
P.S. There are a couple different types of cow receivers, the kind that looks like a bulb with three male joints is the most popular one, but I hate that one, because you have to rotate it so far that the flask attached to the far side gets pushed up to the side, so you can only use like 1/5th of the volume or else it spills over. I like the kind that has 4 male ground glass attachments, all of which are down stream from the vacuum adapter. Here's an example of what I mean: amzn.com/B0776N94BB
Thank god for the spoon fed information of youtube because reading is moy difcil. Que es un Dissociative Asparagus, Dr. Rage?
Would love to see essential oil videos as that’s what I’ll be distilling. Probably not the coolest chemistry stuff but essential oils is what I’m trying to make
The drip tip on the short path head is upside down.
Got any shaards bra.
sorry after seeing that i couldn't help it,.
dude nice bong
Ikr
When I type "Short Path Distillation Apparatus" into the alchemysupply site search box and hit return all I get is a page that showing the word "literature."
alchemy supply doesn't sell them as far as i know, it's too specialized.
That explains it. Thanks.
Need this for my bong
Bro can i just use it as budget distillation
Now for molecular distillation..
wait, wait wait wait wait. What the fuck. I've never thought about this "condense water less than its boiling point" thing. Oh my god how many things have I overlooked in my life like this
Sadly "Chem Player" was closed i can't access to get some video from that channel
" Ce compte a été clôturé en raison du non-respect du Règlement de la communauté TH-cam. "
looks like a BONG
ok video
Looks like bong a to me
Here's a basic flow chart for distillation systems!!

Glad covered especially for essential oils! Great channel, just a support comment. See shill tube isn’t all propaganda and censorship!
Looking for coverage of cow adapters! 😃
What’s the cost for this piece?
Our 5L short path distillation 110V is only 436$ not including vacuum pump and chiller.Just send us an inquiry.kedayq.en.made-in-china.com/product/nCgENLovhWkx/China-2L-5L-10L-20L-Portable-Cbd-Oil-Extraction-Short-Path-Distillation.html
Brought here by the short path condenser E and R broke.
God damn ad on this vid gave me a tremendous craving for waffles. Sons of bitches!
I could think of several more "uses" for that glass.... other than distillation....LoL
