I am trying to replicate a patent, but they use glass, but it is very costly for me.
I am looking to obtain a steady 500 micron. Have not use Ar yet . but as soon as I can get stability, I will. !
I will go to the pharmacy and get some alcohol, see what it does

I want to get 500mTorr or just around, i can keep this with the vacuum running. The problem with that is I also want to insert Argon gas inside, so I cannot keep the motor (vacuum) running.
I was thinking coating the inside with resin or some other material.
what do you think??

Its a PVC tube with acrylic plates on the end. Very solid, but I guess its not good for outgassing.
What are the possibility ?
1) cleaning the container ? soap is ok ?
2) USING different material ?
3) add a coating of some sort in the inside ?

hello,
I have build a vacuum chamber out of an acrylic cylinder.
I can get down to 50 micron but if I turn off the vacuum motor the chamber does not keep its atmosphere (air getting in)
What i did is add a high quality valve between the chamber and motor. Sunk everything in an oil bath...
