Clear vacuum tube search
Clear vacuum tube search
(OP)
Hi, I'm trying to find a material that is clear (possibly acrylic?) that I can hook up to a vacuum pump for some testing we need to do. The ideal solution would be something that is 3/8" dia and it only needs to be 4 or 5 inches long - a test tube would be perfect, but it has to stand up to a vacuum - I could insert it into a vacuum hose and hook the hose up to our manifold.
Any ideas?
Thanks!

Here is an online calculator for stress in a tube with pressure differentials. I did a quick calc for 3/8" ID, .125 Wall... the stress was miniscule... tinker with it.

If I am reading is correctly there will be NO differential pressure around/in/outside the "tube. Basically you could put almost anything in there as long as it not alive or closed ended??

Depending on the amount of vacuum - I have broken them - sometimes - sometimes not. Like that answer??
