Hello,
my name is Arnost, I'm working for CSRC company (www.csrc.cz). We are looking for some degassing equipment and I really like this arragment: Complete Vacuum Degassing System (

But maybe I will need bigger vacuum. Could you please tell us maximal allowable pressure applied at these products:
Professional Resin Infusion Catch-Pot

Thank you in Advance,

If a chamber can hold 100+ psi on the inside, then surely it can handle it from the outside.
Not so...
An experiment I did as a school kid (many, many moons ago) was to boil a small amount of water in a tin can over a flame. The lid of the can was then put on and as the water and air in the can cooled the internal pressure reduced, resulting in the atmospheric air pressure on the outside crushing the can.
Yes... But such a can would have failed with very little internal pressure as well.

I don't see why the chambers couldn't hold far more pressure than absolute vacuum. Perhaps this is...
