High Vacuum Chamber Basics, Part 1

thank you for much

I am about to set up three vacuum chambers, and this was a great overview; thanks!

Nailed it. Is this just a hobby? You're hired!

Thank you.

Great job introducing high vacuum machinery & basics!

when will you be able to build a compact machine like a 3d printer that can print any silicon ship by feeding some wafers into it?

sweet system. i dont know much about this subject but your turbo facing upwards like that gave me anxiety. i can picture something falling into it

i worked at Vacgen for 25 years 20 years making flanges 4 1/2 to 16" must have made thousands 304 and 316

You should do fusion

Thank you for sharing your knowledge with us. I've been working with E-Beams for a couple of years and high vacuum is the main thing in these machines. Gasckets, flanges, and pumps are very familiar to me. Very interesting and complicated field..

Damn, I bet you could fry a chicken in about 30 seconds with that thing.

Very few channels show us nanotechnology equipment! Great work man!

99 percent alcohol :)))

I'll just buy some diffusion pumps off ebay I said. I'll figure out a way to make a cheap vacuum chamber for sputtering I said... Oh boy the rabbit hole I'm diving into.

Why isn't the turbo pump just attached directly on the side. The right angle pipe would increase the chance a particle would be rejected bouncing through that port, right?

How do those VCR gasketed pipe joins compare to yor-lok fittings? Both bite metal to metal

thank YOU

Great tutorial! If you do more of these in the future, please consider using whiteboard sketches to illustrate the flow paths.

Thank you.

Where you get all this component

Thank you so much for this video!

How did you afford all this? What do you work with? That must be e few hundreds of thousand dollars!

Do you practice torquing down the bolts and to specs ? Once done o rings are introduce to heat then it’s best to replace them . Our -8o o rings are about 25o $

Ni vcr gaskets are good also

We need to be friends. Hopefully getting a job soon where I can start affording that stuff. Got myself a diffusion pump and a box on conflats the other week along with calibrated HVDC source 🙌 excitedly looking forward to a few more of your vids 😅🙏

Why does the chamber look so overbuilt? Is the vacuum that strong?

can you make high vacuum pump from 40 pvc tubes?

I have got another idea on how to make ultra high vacuum pump:
- Make a cylinder out of metal (the crankcase)
- Make a cylinder that fits that cylinder with a 1 micron space (the piston)
- The shape of the inside cylinder must be bumpy towards the center, so plastic would adhere to it
- Fill the (1 micron) gap between two cylinders with nylon 66 , it is a naturally lubricated plastic compound
- Using a good amount of force, remove the internal metal cylinder , the nylon 66 would un-stick from the outer cylinder and you would get a piston that will fit the crankcase with no free space between them, it would be atomically fit, it wouldn't be 1 atom fit, it would be practically 0-atom thick with no possibility for other matter to pass between. You could probably make a nylon 66 coating on the crankcase too (and do this inside a nitrogen jail to avoid oxidation of metal) , this way you would have nylon 66 coating on both, the piston and the crankcase, because otherwise the oxide on the metal might not be a good to support the force generated by the vacuum. Must work a lot better than an o-ring.

Make sure to wear gloves when touching parts. Proceeds to touch every part bare handed...

well explained, Thanks!

thanks for sharing! super helpful!!

Thank you for the video! It is impressive work! How did you learn to do all that?

Thanks a lot for the detailed vacuum chamber basics. I am new to semiconductor chip making industry, and needed such overview video.

Great video, very useful, thanks! Stupid (?) question: I don't see too many KF10 clamps -- are KF16 clamps compatible with KF10 flanges?

Get rid of the acetone residue? Are you freaking serious? If the acetone has some non-evaporating stuff in it, then who's to say that the same thing isnt true for the isopropyl alcohol mixture? If you're that worried about non-evaporating stuff in acetone, you should distill your acetone instead of using isopropyl alcohol later on

I'm gonna put one of these in my bedroom right by the window so my neighbors are always on their toes wondering what I'm doing.

thanks so much for sharing! awesome video!

Very expensive hobby.

What's your job role ?

I make all its mechanical parts . Can you tell me how career growth can happen in this?

Is there a reason you use the tapered down conical KF for turbo pump or is it just for dimension purposes.

What's a suitable pump for long term use hydration of waste vegetable oil in an old LPG gas bottle, for home processing to get water out of the veg oil?

Thanks for the video

We found scroll pumps much more reliable than membrane pumps over years scale. This was important to not pump air in case of a rupture in the membrane pump, for helium recovery.

Once of the best intros to high vacuum!
