Hi, I am trying to build a vacuum system that need a chamber with >8"
inner diameter and >10" height. This system will be working at
hundreds of mTorr so it will be very easy to achieve.I am tight on
budget so I just want a used one, preferrable one taken off a bigger
vacuum system. However, I couldn't find anything that is below $1000.
Can anyone suggest a place that sells used vacuum parts cheap? Thanks!
