How to get a Sample from A to B in an Ultra High Vacuum System

A few weeks ago I visited Daniel from Omnivac. This company specializes in the development and construction of ultra-high vacuum components and entire systems. We talked about many highly interesting topics. Inverse Photoelectron Spectroscopy, Electron Beam Evaporators and Ultra High Vacuum components in general. In this video I will talk about Radial Distribution Chamber (RDC).
„The OmniVac RDC Distribution Chambers are the central element of our multichamber UHV-systems. It provides access to up to 8 individual chambers for e.g. preparation, storage or analysis. The RDC distribution chambers start with a diameter of 700 mm and offer a translation distances to each sample holder station in the different chambers beginning at 475 mm. An optional telescopic transfer arm allows for transfer lenghts up to 820 mm.
For sample holder reception and fixation a carabiner mechanism is used enabling safe and reliable transfer of your samples. Under common conditions a transfer can be performed in less than one minute, enabling nearly continuous heating or cooling of a sample.
Up to three DN 250CF windows provide full optical insight to all phases of the sample transfer process.“

[@That_Chemist]

I would definitely be interested to hear more about the specific use-cases for instruments like this!

[@AdvancedTinkering]

I will try to make a video about it!

[@nomcopterlabs]

Agreed! Such interesting specialized equipment.

[@quantummandavid]

Hopefully, you put dr fauci's face up next to the door and open it. since he sucks so much he would be in the ideal environment where he can suck even more.

[@lamarrrrr]

Okay, this is now my favourite channel on YT! Please, do more vacuum chamber videos, it's such a hugely important niche for research and manufacture! All the thin film tech we invent now, can be scaled massively when we build factories in orbit!

[@AdvancedTinkering]

Thank you! I greatly appreciate hearing that you enjoy my videos! There will definitely be more vacuum related videos.

[@SGregW]

This is one of my favorite channels on KZbin - great content! Hopefully you can do a review/teardown of that TOF-Mass Spec in their basement.

[@AdvancedTinkering]

Thank you! I appreciate it. If I had the space to do so, I would love to open up and try to repair it. I will have to wait until an opportunity arises.

[@MartinDoesStupidThings]

"Would you like to see..." "YES" Awesome video as always!

[@AdvancedTinkering]

Thank you! I will try my best to make another video happen!

[@GTS00000]

awesome video! Needless to say, everyone here wants to see the repair of the broken Masspec!

[@biberhahnderheftige7725]

Ich liebe den Sound einer anlaufenden Turbomolekularpumpe! 😘

[@Vactron]

Awesome video. Very useful

[@The_Dude96193]

This chanel is so underrated

[@AdvancedTinkering]

Thank you!

[@DEtchells]

Wow, that is some expen$$$ive-looking equipment! I’d love to see a repair/refurbishment of a mass spec!

[@JainZar1]

Die Reparatur eines TOF-MS zu sehen wäre schon spannend. Ich hab damit zwar vor knapp einem Jahrzehnt im Schülerpraktikum gearbeitet, aber das mal von innen zu sehen wäre Klasse.

[@AdvancedTinkering]

Ja, das fände ich auch ein wahnsinnig interessantes Projekt. Das Problem ist einfach, wie groß das Gerät ist. Dafür habe ich in meiner Wohnung keinen Platz. Aber eventuell lässt sich dafür eine Lösung finden.

[@tomyorados974]

@@AdvancedTinkering Vielleicht kann TecKonstantin ja helfen bei Reparatur und Unterbringung. Der hat auch schon einmal eine Turbomolekularpumpe repariert: kzbin.info/www/bejne/Y5vXeKOVZ7FoZq8

[@HuskyMachining]

I find ultra high vacuums super exciting so I would love a mote deep dive into every peiece of UHV equipment!

[@user-if2gz7fi9r]

This equipment is a piece of art ❤.

[@cromatico524]

awesome content! plz keep going!

[@AdvancedTinkering]

Thank you!

[@rezganger]

THIS is the objectively best type of marketing! -based on science,projected thru functions. very cool video. objectively speaking,of course.

[@Sparky-QQ]

Dope video please continue this type of content if possible!!

[@tnmoe-]

AlphaPhoenix has a couple videos with a crazy vacuum like that too. Cool stuff, ay.

[@AdvancedTinkering]

Yes, his UHV videos are definitely worth watching (basically all his videos are great)!

[@BajamBM90]

Cool video! I am curious about what types of experiments are carried out in these systems

[@AdvancedTinkering]

Thank you! One of the systems is used for photoelectron spectroscopy. If Daniel and I both have the time, I will make a video about those. Or maybe an in depth video about leak detection.

[@OfficiallySnek]

@@AdvancedTinkering I don't know where, but there is already a video on KZbin about leak detection. I'm sure you could add additional information though.

[@OfficiallySnek]

Found it, kzbin.info/www/bejne/jHWZapaohKurZ5I

[@purza95]

@@AdvancedTinkering I service electron microscopes and have seen similar apparatus in some labs. What is photoelectron microscopy? I know high energy electrons striking an atoms orbital electron gives off characteristic x-rays (i.e. photons when they change orbits) when they change shells. Is this what you are referring to?

[@GerCrusader]

@@purza95 its a ultraviolet source attached to the chamber, it excites the atoms to emit electrons. These will be analyzed in the spherical shaped insturements to the side. Those are electron energy analyzers. It is a type of spectroscopy, not microscopy or spectrometry. You analyze the energy of the emitted electrons and measure the energy band structure of your sample. You can use photons of different energies to exite the atoms, on this system the uv source emits uv photons, but we also had an x-ray gun installed some time ago to do XPS instead of UPS.

[@johndmcmaster]

lol seeing that TMP at the end...I just reassembled and fixed a TPU 240 today and did a similar spin test

thank you very much , i need to know about PEEM and LEEM and electronic beam evaporator

[@williammorris1763]

Super cool! 🔥👍

[@AdvancedTinkering]

Thanks!

[@sanatron]

That is a very cool vacuum system.

[@Viscool8332]

I wonder how are the clear parts of the view parts sealed for UHV? Is it by a copper disc like the other connections or is it by some other method (wouldnt the glass/acrylic? break when trying to deform the disc)?

[@goamarty]

with all that mechanics in the ulro high vacuum I wonder how this works without lubrication. At least I can not imagine any oils usable there.

[@QTRAPQTRAP]

Do the ToF Video!!

[@RainOrigami]

incredible

[@AdvancedTinkering]

Indeed. Those UHV systems look really impressive.

[@onelastcast03]

Hello, good explanation, thank you! There was a series of vacuum tube fitting shown around minute 6:43 on the stainless tubes. Would you know what they are called or where to find them please? thank you! I believe they are a combination of Swagelok with a double knife edge being compressed when fighting the swage nut. Thank you!

[@AdvancedTinkering]

Thanks! I think you are talking about CF vacuum flanges. They are used for UHV and are pretty expensive and the copper gasket should only be used one time (but you can reuse them in some cases). You can get those flanges at almost all vacuum part suppliers.

[@genghizalseitov3807]

Hi, are they selling any no need staffs, like baratrons, mfc in reasonable price and etc.? Regards

[@thesunexpress]

How are vacuum leaks mitigated where the various motor/manipulator shafts exit from the chamber? Presumably at least some of the bearings in the motors are ball-bearings rather than bushings... wouldn't those be really leaky?

[@XanatosDavid]

There are a few types of rotary feed throughs, the best with regard to not leaking are magnetic once, thay have a magnet in side the vacuum that couples to one outside and allots to transfter the rotation. Other types, would be metal shafts sealed with a ferro-fouidic seal doof to 10e-7 mbar and can handle rotation speeds up to 100hz, or you could use a regular Viton seal around a shaft here you can only rotate it slow, such arangements ofter have a second seal and inbetween you apply some rough vacuum.

[@Cewu]

Very cool video... but onto the real questions: How specialized is that high pressure aluminum foil on the chamber? XD

[@AdvancedTinkering]

It's heavy duty aluminum foil. I don't think there is a UHV Lab without aluminum foil :D

[@GerCrusader]

the foil keeps the chamber warm on cold days ;) either it is used as a replacement tent when it is not done yet or to plug some holes in the tent. These have to be there because the customer will attach chambers to these ports.

[@jscudderz]

Actually pretty specialized, it's thick and bought for vacuum stuff and is more expensive than regular foil

[@jimpanse1638]

8:03 I thought running a turbomolecular in ambient pressure would destroy it 😮🤷‍♂️

[@sewsim5963]

MBE? Danke

[@GermanMythbuster]

You gave me horrible anxiety seeing that turbo molecular pump spinning up under normal atmosphere at the end! Stop it! 😫😖 😅

[@teresashinkansen9402]

Some turbo pumps actually need to be run at atmospheric pressure for some time so the lubricant spreads around when they haven't been used for along time.

[@quantummandavid]

Why is there so much aluminum foil all over it?

[@AdvancedTinkering]

I don't know exactly what you mean. But the aluminium foil is used either to cover open flanges on vacuum chambers to prevent contamination from entering or for insulation while the chamber is being heated.

I don't see any video you made in your non native language ;) And my English viewers don't seem to mind.

[@Chris_Garman]

+1 for GCMS video.

[@sealpiercing8476]

Haha I never got into that kind of clockwork when I did stuff that involved making ultrahigh vacuum. If you need it you need it but I bet it can break down in amusing and painful ways every now and then.
