Acrylic can be scratched easily Hed been restoring an old tractor and didnt know that the big tires ran at a *much* lower pressure than a car tire. Finally, due to its material properties, acrylic vacuum chambers require thick walls even at small vacuum volumes in order to withstand the stress of ambient atmospheric pressure. Cost Effective - Acrylic Chambers cost a lot less than Steel or Aluminum and have their place in low level vacuum applications. Acrylic transmits up to 92% of all visible light; this makes it one of the clearest materials known to men (glass transmits about 85% of all light). This vacuum range opens doors for a plethora of applications, experiments, and processes that can be conducted utilizing an acrylic vacuum chamber.

An acrylic vacuum chamber is flexible and will, over time, conform to the assembly it is connected to. Acrylic is strong but brittle It works pretty damn well and takes up no more space than the pan on its own as the polycarb sheet stays on top of the pan with the lid on top of that (pressure cooker lids are usually quite deep so the fittings are all covered over) so all it gains is the thickness of the polycarb sheet and the airline fittings in height. Interesting, although the outgassing of most plastics under vacuum is severe. Of course, my wife was calling 911 as I ran across the street. This fact eliminates acrylic as a suitable material for high temperature applications. Acrylic is fairly resistant to chemical attacks. Is this an industrial vac chamber robust to withstand constant use or is it one of these low use types of clear vacuum chambers?
