- I demonstrate the importance of surface adsorption and use it to produce a clean, low cost type of vacuum pump.
Note: If you ever notice the pressure meter go blank don't worry, there wasn't an issue. The meter automatically turns off to save power.

“Any physical principle can be treated like a hassle or a problem or a challenge...or a tool.”
We had a terrible principal when I was in HighSchool
He seems to have hinted that it could also be used to separate a solvent in an extracted oil?
Could he fill a column with the beads and then run solvent across an organic material like peppermint/garlic, dumping the output into the column full of beads, where the beads will adsorb the solvent letting the oil pass through?
I guess you could weigh all the gear at the start and tell by weight how much separation you got. Hmm.
@@V0S1N0 depends on the physical size of the particles, but it does seem that the process takes time at high concentrations, so you would likely need the molecular sieve to sit in the solution.
This is a common way to purify ethanol to 100% after distillation
And when you have a problem, you have a problem, but _sometimes,_ when you have 2 problems you can use them to solve each other.
he's really layering up the puns in this one. dad level 420 achieved.
Your channel is underspecced.
You deliver a coherent, flawlessly articulated, observably scriptless lecture on whatever you tackle. Astounding!
Thanks!
I have never seen someone know more about so many diverse topics... Love this channel. Keep up the great content 'Tech'.
A modern polymath indeed.
We use cryopumps in my job to pump very large volumes down to high vacuum. They're quite cost effective at that scale, and have an important advantage over a turbopump, in that they can fairly easily deal with gasses that are intentionally released into the vacuum system during a process. Turbos also have trouble with non-gaseous particles, whereas a cryo will not be damaged by such things. Turbos can be much more sensitive also to heavy stuff like noble gasses, where a cryo can just condense whatever you throw at it, within reason. With a pair of pumps, if one becomes saturated, it can be closed from the system with a valve while the other continues to work, and regenerated without compromising the vacuum chamber.
They're definitely more "primitive" than some kinds of vacuum tech, and can have serious drawbacks, but within their niche they are extremely useful.
thank you for that info.I want to learn as much as I can on subject.
Out of curiosity, have you ever experimented with hooking another pump in to regenerate the cryo pump without removing it from the system? I'm personally curious about vacuum ejector systems that scavenge their working fluid from the material to be removed, but the general case is a point of curiosity itself.
@@absalomdraconis By removing it from the system he means closing a valve and not physically taking it out. If you look at how o2 concentrators work that is exactly what they do. They have 2 chambers full of the filter medium (Usually something to filter nitrogen) and while one is working the other is regenerated and then a valve switches over and the other works while that one is regenerated. To regenerate them you just need to heat it (with internal heating elements) causing the gas to expand and boil off. These systems are often used by glass blowers because they need huge amounts of oxygen to "fuel" their torches.
@@excitedbox5705 : I was _already_ aware of what was meant by removing it from the system.
Unfortunately cryopumping doesn't work well with helium gas, I still need a turbo.
My ONLY complaint - EVER! - is that every episode ends WAY TOO SOON! I'm just really getting into it - and then - WHAT?? - IT's OVER!?? Thank you for your great work. Aloha
I'm about to up my patreon level. We all should - this really is the best content on YT. More Patreon supporters = more//longer VDOs. :P
@@allenmueller - On behalf of all the broke people out there who are struggling to get by, a sincere THANKS to you (et al!!) for using some of *your* money to support his labor-of-love output (and/or those of other valuable creators), for all of us collectively, when we genuinely want to, but presently can't. Really means alot to me man.
I see the clock in the background is often later in the evening on Tech Ingredients' videos. I love thinking that Mrs. Main Presenter is glaring at the lads, 'I'm not cooking dinner each night for you to be sneaking off to the shed before we sit down to eat it!" Main Presenter, unscrewing the back of the microwave while its heating through some beans: "Oh, yes love. I'll get the cutlery after I add an inlet for the gas exchanger we're working on."
🤣
The real question is: As it is a 12 hour clock which 12 hours is it?
This is the sort of stuff I wish they taught in school, practical experiments to demonstrate the theory.
Get the next generation excited about science.
I continue to be impressed with the way you can explain complex concepts and make them easy to understand. I so love this channel! Science IS fun. Please keep it up.
I agree completely. This guy is a great educator
Cannot speak highly enough about him
Camera person: please use another camera for the meters and merge the images with picture in picture... It is really hard to read the display.
Nice video!
I second this. I watch on my phone and dont even bother trying to read the meters anymore
I third it!
Very good idea
Yes, please! Camera 2, zoomed in! [Sometimes viewers use a pocket-sized screen (smartphone).]
Also - if spelling out a difficult name - just flash it on the screen; most of us can read!
(I'm a bit dyslexic - but I have a pause button! Doesn't work if you just say the words slowly)
60 yrs old I now know the difference between absorb and adsorb, never to old to learn something. Fascinating as ever.
A DIY oxygen concentrator for welding would make an interesting future project.
Oxygen concentrators are frequently used with propane instead of oxygen/ acetylene for brazing set ups. I use one for bicycle framebuilding.
@@shirk15 why would you have to use propane instead of acetylene?
@@xenonram people are afraid of acetylene
@@xenonram it is much easier to get for a diy home use. Also safer. It gets plenty hot enough for fillet brazing with nickel bronze brazing alloy. When you run out on a sunday afternoon you just steal the tank off your bbq to finish your project.
@@xenonram sorry I misread that, you could use acetylene if you wanted. See previous reply on why I decided to use propane instead.
With a masters degree in physics and a job where I work with vacuum systems on a daily basis, I never met anyone who explained the priciple of cryopumps so well.
"Science is fun isn't it?" Should be the new tagline of your channel
My brain went on horror movie mode and seen the glass exploding in his face with no protection. Thank God that didn't happen, would never hope for that, my brain just went there in a split second,
I loved his childlike happy smile when he said that. Was fun.
I will put this in my thesis epigraph hehehe
His half-broken nerd smile killed me :D
out of 208 of my subscriptions , Only 3 of them have a bell notifications on. This channel is one of them.
I'm sure you've heard this countless times: YOU are A M A Z I N G ! Love your vids. Love your teaching style.
Thanks!
Never too much.😁
20:52 I absolutely loved your expression when you mentioned fusion generation systems. Your passion and knowledge of science is so natural and obvious. I can't help but feel immersed in the amazing world you live in where subtle understandings of nature are so miraculous and awe-inspiring.
Thank you for sharing your abundant love and insight with the global community you've created and continue to grow. It is an honour to be a part of it and a wonderful privilege to glimpse these brief moments of your journey that you selflessly and painstakingly offer the world.
P.S. I'm super excited for the oxyhydrogen-based shaped charge devices you are planning. Stay safe!
That was the one thing I noticed in this video. He already said we're doing a series on topics related to why he believes fusion generation will be commercially available much sooner than most people think, so there's definitely a hint of "in later videos..." when he smirked like that. I can't wait for more.
I love the videos, but on a smaller/lower resolution screen, it can be challenging to make out the various instrumentation measurements seen in your videos. If you agree this is an issue, I'd suggest adding little "expanded view" enlargements. These should be fairly easy to do for static shots in your video editor.
On a different note, I found the description of how our visual systems respond to low oxygen strikingly magical.
yea, seeing the read-out on meter would be helpful.
I had the same problem. The meter wasn't readable on my phone, especially when the resolution dropped due to my cellular connection bogging down. I would appreciate it if you would try to narrate things like meter readings which may be hard to see on some screens. I still enjoyed this video and learned from it.
I'm on a reasonably decent 17 inch screen about arms-length away and could not make out the display on the meter.
I couldn't see anything on the vacuum gauge while sitting 4 feet from a 55" UHDTV. I thought maybe the instrument had one of those newfangled invisible ink displays.
@@karlharvymarx2650 i would have never expected to have to say that: but 4 feet is too far away from a 55" 4k screen ;) at least if you use full Resolution.
There's no doubt in my mind that this is one of the best science channels on CZcams.
People like you and channels like these are part of the very limited and much needed entertainment I consume nowadays
I remember that achieving and maintaining a vacuum was one of the hardest parts of the DIY mass spectrometer over at Applied Science a while back. It's amazing how many and varied projects use these principles! Thanks as always for an informative and entertaining video!
Sure!
I was involved in building two of these in college back when the cheapest pre-built system my university was able to get was coming in at $1.8M. The two we built only cost $67K in total, basically pocket change in comparison. This takes me back for sure, really interesting stuff and I'm glad to see someone covering it.
We used liquid helium to cool ours, like you mentioned, and we used custom built ceramic heating coils running with a very complex array of thermometers to monitor heating and cooling. The hardest part was building the heating and cooling arrays, a lot of extremely fiddly TIG welding and expensive fittings went into them.
We did use the sheet configuration you mentioned, the sheets were manufactured by one of my professors and his team of post-grads in the materials science department. It was a huge project, we went through a variety of prototypes. It took us a year and a half to produce the final pump.
Our very first (functional) proof of concept looked a lot like what you have in this video, and it worked *almost* as well as the final full scale pump. Great video, I really enjoyed seeing you explain the concepts behind it. What you said about physical principles and their utility as tools, that's very insightful. It's people who see solutions where others see problems who make the biggest changes.
Wow that would have been an exciting project to have participated in.
Your philosophical analysis is solid as well. Thanks!
The Department of Education should give you the top prize for the best science lessons ever plus a considerable grant for future projects. On top of that, the ministries of education of other countries should give you medals for the best CLIL lessons of English (Content and Language Integrated Learning). You're just absolutely brilliant, man.
This man is both very intelligent AND practical. A rare combination
Used to have "bakeable" foreline traps on our spectrometers that were filled with sieve.
When I worked with vacuum systems I used a liquid Nitrogen chilled “ Cold Finger “ which trapped remanent gases within the system. Coupled with an ion getter pump high vacuum was achieved.
High power radar components?
Microwaves ... ?
The scientific content, the previously unhead of concepts and straightforward explanations juxtaposed with the dead pan humour makes this a favourite channel. Simply fantastic.
This channel is better than a college education, and not nearly as expensive. Even when you have to rebuild the garage because you missed an important step on safety. Just Sayin
Your experiments make me think I'm smart! Thank you! Best channel on CZcams...the internet!!!
You are, no joke and no excuses...now do something meaningful!
I would have been interested to see a comparison with the empty flask being heated and cooled to similar temperatures to see if it got below the pumps vacuum level
I have used cryo pumps in thermal and e-beam evaporators but I have never seen such as excellent explanation about the principle behind cryogenic pumps. This video should be shared among grad student and post docs.
Agree with you.
I would like to see the empty vessel heated under vacuum, then cooled in the same manner as with the beads, then the control would be properly established.
I do love seeing all of your videos regardless. You inspire and teach anyone who watches. Thank you.
Just wrapped up work for the day and I got the notification, made my day.
I use 3A sieves to dry acetone when working with certain water sensitive pyro comps. Works very well. They are also physically small enough to use as the seed cores for making pyrotechnic stars as well.
Thank you for this. Longtime subscriber, but this is the first video I've watched in months because of my horrible divorce and my ex-wife not letting my see my son.
I now know what I was missing: man's eternal quest for answers.
Slowly getting normalcy back into my life. I sure hope to transfer my passion for science to my son, one day. One can only hope.
Until then, I will continue improving myself, each day and every day.
You take care, and, once again, thank you for posting your videos.
Brilliant video. You are completely correct that the use of heat blankets or lamps will increase the pump down rate on vacuum chambers. In semiconductor equipment, traps like these are often used to reduce contamination from oil filled vacuum pumps from ever reaching the high vacuum chambers. One effect that we had to teach vacuum maintenance workers... Virtual leaks. A video explaining what a vented screw is and how big an effect a virtual leak can have on a high vacuum chamber would be awesome. A factory can lose so much time waiting for the base pressure to never be achieved due to this cause. Hope your day is really good.
I'm curious to see how well the heating/cooling effect might have without the beads. Just by heating the gas molecules, the pressure would be raised enough for the pump to remove a few more, and cooling it back down would lower the pressure. Then it can be a straight comparison for the performance of the beads.
There are for sure Zeolite traps which are not refrigerated, and might have heaters attached to them somehow. So, they do SOMETHING (catch water I think, which is important) and/or catch the oil from the mechanical pump. You can buy them for either service, not too expensive. Simple and rugged. I think the cryogenic one has much higher performance, but the heater-only kind might be cheaper to run, and just in general be big and dumb.
I always learn something, and often many things every time I watch your video. I love science, and the application of it even more. Thank You!
Just like most of the things you said i don't understand why your channel is so underrated
This is the most advanced engineering channel in YT.
thank so much for this and all the vacuum series; I am now in the process of creating a plasma lab; I have the building mostly completed and procuring ALL the materials & equipment; the list of things is getting quite large & expensive.With your help , (maybe) with the list of stuff, so I can get this right. When I first started this journey, had no idea how involved this was going to be, but some times ignorance can give you courage. : )
With the new intro music my mind automatically made this up: Wel-come back-to Tech Ingredients! 🎶
I've heard this described but I've never seen a good example. Good golly, good job. I don't have kids, but I will definitely try to get my eldest niece to check out this channel. You're pushing out extremely good content: knowledge.
What I know is a drop, what you know is an ocean. Thank you for such amazing videos. The amount of knowledge you have is lightyears ahead of me.
I really enjoyed the story about the observation station - and the thin air. Would love for you to weave more of your background and history into videos, with anecdotes just like this one.
Another great video from Tech Ingredients. Looking forward to the Tesla Catamaran!

This is wonderful content. Thank you for digging into vacuum science! More please. As you have an interest in HV/UHV, and have mentioned fusion several times, I would love to see a series on Farnsowrth fusors or something similar. Thanks again.
Man I am so happy you exist. One day we will look back on your channel and realize a bunch of engineers and scientist started because of you.
I am one of them, thank you.
Fantastic!
I want to sit down and binge everything you have posted. But I know I wont learn it all that way. Thank you sensei. I will study it all.
Always amazing content, thank you for providing such a valuable and enjoyable content.
You're a contender for the best mad genius on CZcams
Keep up the great work =]
I am in Europe, so an internship is immensely impractical for me, let alone a job or simply work as volunteer for fun and science (yes, science IS fun. That is why I did a MSc in material-science).
Effectively you and your team (including wife ;) ) are already an academic institution. I guess making it official involves a ton of paperwork etc, taking the fun out of it.
But I do remember while living on campus going often with a big smile to "the lab" during the last years at uni, as well as the satisfaction of actually doing somethings that adds to the world.
Your teams' "institution" certainly adds to the world.
I feel similar about Robert Murray-Smith, you guys are genii (is that a word?) out of magnetic confinement bottles. No putting it back either, or a limit of three wishes... science !
Cheers, G.

And one important factor - your emphasis on safety. Love it!
Thanks!
Does anyone know when we are writing tests?
I hope it’s open book...

I like the eloquently presented mechanism of the "van der Waals" force.
I know you said no moving parts but I see you moving a lot of stuff to make it happen. Really cool demonstration I don't think I've ever seen someone explain pressure and thermals like this before..
I find it interesting that you mention waste. I would be interested to see a video on how you handle hazardous waste and best practices around dealing with substances that if used incorrectly could be toxic to either oneself or the surroundings. I know it’s not particularly sexy but as a result of that there’s not much about the subject that isn’t incredibly dry and formal.
Great vid! Can we get a PIP view of the gauge next time? Thanks!
Great vid, thanks. This is useful feedback, I can rarely read your in-frame meters, you should do a screen test at the time and/or consider picture in picture blow ups.
This guy is like a "black hole" for physical knowledge, and WE volks have the great chance to watch BEHIND his event horizon ...

I used to work on UHV systems (~10^-11 torr). It was always amusing to show them to visitors because this gleaming piece of stainless steel high tech beauty was covered in wrinkled aluminium foil and kevlar blankets to hold the heat in when we went for a bake out. Always looked a bit grubby. Wonderful machines.
I am pleasantly surprised you can get a pump easily running to those vacuum levels for ~$250. That is a hell of a deal.

Excellent video, molecular sieves are amazing to work with. I worked with Lectrodryer and developed for our plant an ability to make ultra dry solvents on a large scale using highly activated 3A molecular sieves. I was able to produce 1 ppm water acetonitrile, and 3 ppm water THF on a large scale. We developed a Cycletainer system to store and transport the material. The system used Argon as the inert gas. I also used a small amount of indicating molecular sieves in the system to remove peroxides. The Lectrodryer system super activates these sieves by blowing hot nitrogen gas down the column.
I really appreciate that you take the time to clarify words.
I've spend so much time on other videos trying to listen to what they said exactly.
This was definitely "kind of interesting."
Thanks for another great video.
Can you try epoxy with steel wool as a cheap alternative to carbon fiber?
Weave it and epoxy it for maximum strength, but I'd assume most steel wool wouldn't have a high tensile strength. It would be interesting vaccum bagging a bunch of it so it compresses by itself lol
good tricks i learned to add to my vacuum-armamentarium
armamant... wait.... what ?
Looked it up. Apparently it is a real word, and he used it properly.
That's a pretty neat thermal transpiration pump you've got there. I'm always impressed by the ingenuity and interesting materials displayed on this channel.
Another great video. In the lab the bake out process can take hours to get all the oxygen and water off the inside of the chamber walls. For UHV systems the chamber material becomes important because helium atoms are so small they can squeeze through solid walls and you will get some leakage no matter what. The microscopic world is truly fascinating.

I just discovered your channel, thank you for making it. I'm an engineer and pilot so I'm always learning. I absolutely enjoy your video's! Very well done. I tip my hat to you.
you guys are by far the most interesting tech people i've ever encountered.
Your video’s are amazing, you make it very easy to understand. Always loved science and how things work. Fascinating
I have been fascinated with PSA systems for a while. Specifically their use in bio-methane purification. Great video. You're the only channel I have hit the notification bell for.
I have made a similar comments before on another video, but I just have to say it again, these videos are fantastic, there is so much work and research behind them, and I know they take a long time to make. Big thanks! I really hope the income from your channel will be enough, and hopefully more than enough, to make you feel comfortable to continue making these videos. I know it is your passion for teaching these things that drive and motivate you, but I also know that it costs lots of money and time.
That random fact you threw in about the observatory is amazing, never knew how sensitive vision was. I wonder if that's why I used to see weird colors when I used to hold my breath under water. I'm sure if I had an o2 sensor on it would be beeping.
Wow! I loved learning about low light vision and oxygen deprivation! Recreating that would be so cool.
Since a bunch of kids are moving to online schooling now, these videos should become part of a curriculum.
You just gave me a great idea to attempt to test how much water is in my competitor's products compared to ours. This is my favorite youtube channel. You are awesome.
I don't know your plans, but you can use some freshly dried molecular sieve and measure its weight gain after it has dehydrated something.
so cool, your demonstrations make so much sense, also really liked the side story about Mauna Kea

Awesome channel, wish more people were like this. Unfortunately, it can be so informationally dense that I can't watch them for hours on end! 😝
We use cryo pumps in the semiconductor industry. Sputter tech uses a diaphragm pump to pull down the chamber / cryo to their base, then we introduce an inline turbo to help the pumpdown and introduce incandescent light to "bake out" the chamber. Once we hit 1e^-2 Torr we then turn on our cryo pump. The cryo pump takes about 1 hour to cool down from 300 Kelvin to 64 K. After the pump has hit 64k, we close the gate valve to the cryo and let it chill further to ~4-7K . Once the cryo is fully chilled, we open up the gate valve and it will pull the chamber down to 1e^-7 Torr! It's really fun to control and watch. After the cryo has had it's fill of argon or we need to perform PM's we close the gate valve and turn on a heater element which will shoot out all the gas it has collected via a exhaust port. But we reuse the cryo pump hundreds of times without replacing any parts typically for about 4 years before the desiccant becomes exhausted.
Back in the 1982-84 time frame I worked on ion beam implanters for the dopping of silicon wafers in the process of making IC chips. We would vacuum Down a chamber first using a mechanical diffusion pump then cryogenic pump after all the items stopped out gassing due to the low pressure we could reach down to the milli tore range this would take about 3 days I do not recall the size of the chamber. This demonstration brought back memories thank you.😀🛫
Everything you do it amazing. I am stunned every time.
