Deacidification tank Oko paper

We need to purchase a tank for deacidification and have looked at the
one offered by University PRoducts (Wei T'o Dip Tank).  Is it necessary
to use one constructed of plexiglass because of chemical reactions or
would it be possible to use a less expensive plastic or stainless steel
tray like the ones we use for washing?

Also, what sources are available for a heavy Oko or some comparable
paper used in making hollow tubes for the circulating collection?

Thanks very much.
