content: Hi All!I've started a new project recently - I want to build a vacuum deposition system at home. It might sound a bit crazy, but it's not - it's very crazy.Because of that I'm searching for vacuum equipment. Everything might be useful, especially if cheap or freethe shipping alone will kill me probably. If you have any chamber parts, fitting etc please contact me, I would be glad to obtain them, even if they are old/leaky/damaged. Also valve, pumps, pump controllers erc would be valuable for me.Regards!

content: Quote from: jonpaul on January 24, 2021, 11:55:07 amLocation: Poland / EUSystem size: depends on the chamber I manage to source. If I will have to construct it on my own, I've seen glass cylinders/pipe segments with volume of approx. 25 liters (Φ 300 mm, height 330 mm), so 50 l tops. The pumps seem to be of least concern (now I have Leybold Duo 2.5 and Turbovac 50).Target pressure: uhthe lower the better. Would be great to get to the 10^-6 Torr region to be able to do low temp. vacuum deposition of organic compounds.I need everythingalthough I've seen some gauges here and on eBay, that are reasonably priced.Regards!

content: Hello,if the author do not complain I would contribute to the topic.Some years ago I also started to collect a vacuum system components, but just stuck when got a vacuum chamber without a door. Since that the project was forgotten.Maybe someone has a propper door for the vacuum chamber from autoclave Tuttnauer Elara 11" ?

content: Nice chamber, but from what I see it's for high pressure, not vacuum.

content: Quote from: nikodem on January 24, 2021, 05:28:33 pmUmmm, at first glance, I would read that as being able to do full vacuum or up to 2.8 bar positive pressure.It looks like it says-1 / 2.8 barfor the "allowable work pressure" rating...

content: Yes, its working range is -1 / 2.8 bar, from full vacuum to 2.8 bar.Some info about complete autoclave this chamber is from:https://tuttnauerusa.com/wp-content/uploads/2019/07/Elara11-Operators-Manual-2017.pdf

content: Keep your eyes open and put out the word to your local scrounger's network. One time I picked up a diffusion pump + valving + roughing pump for a few bucks that come off of an electron microscope from a scrapyard. Probably would have taken the whole thing if I had gotten there earlier.

content: I would love to know, where to find such stuff here. Unfortunately, no one scraps this kind of equipment here

content: I can say, to find something realy interesting locally you must have a patience and put some efforts searching from time to time. And if you find, it is likely it will be missing some kind of parts or accessories which prevents you from instant plug&use.
