setting up a 12" stainless buchner Using standard 200/190 proof ethanol and CDA12 denatured ethanol down to -80c to -90c what is the ideal gasket material to use with this system?
silicone seems fine for etoh but not heptane.
Buna-N is the only one i see that is A+ with ethanol and heptane. maybe i just answered my own question lol
