I got a 5 gallon vacuum chamber. The lid appears to be plexiglass. The vacuum gauge will actually measure down to -30 psig, which is impossibly low.

That seems more likely. The only thing I am aware of that hits -30 psig are very talented escorts.

I hardly ever use mine because it tends to splash a bit, and sometimes a hose pops off. I'll use it a more when I get the minor kinks worked out, but
it's less messy to use a vacuum pump or just hook the aspirator to a water faucet.
I'm away from my lab for the next couple of months, but I'll check out the gauge on the vacuum chamber when I get a chance... inches of mercury would
make more sense than psi....
