Polyprop is pretty safe with most chemicals and widely used for laboratory
products. It will hold up well and also has good temperature
characteristics. However, when I looked at the price of 6mm sheet (need
something rigid enough to do the job properly) I chickened out. Even 3mm
sheet is bad enough.

When I have the time to do it, I think I'm going to go with 9mm ply and
the acid resistant paint.
