Mary,

It is more likely that the quality of the Formaldehyde is the problem rather
then the zinc component.  If you search the Histonet archives I am sure you
will find many responses to this ongoing (world wide) problem.

> I have a pathologist who insists that fixing tissue in Zinc Formalin is
causing poor nuclear detail and an overall cloudy appearance.  Has anyone
out there in histoland dealt with the issues caused by zinc formalin in
there lab?
> Thanks for all the responses I am sure to receive!
