i have been using zinc formalin for everything in my lab for at least the last 6
years.  no cons that i know of, lots of pros, i have almost completely
illiminated the need for any HIER and can use mild enzyme digestion as
pretreatment or none at all.  there was a rumor that zinc formalin percipitated
out damaging tissue processors, i have not experienced this at all, even when my
tissues are processed with FF tissues on the routine histo processor.
