Hi,
does anyone have a recipe for a home made zinc formalin fixative?

Is it true that zinc will precipitate above pH 5.

thanks a lot

We do it as follows:
2 l distilled H2O
50 g ZnCl2
2 ml concentrated acetic acid
300 ml 40% formaldehyde

Morphologists of rentgeno-radiologic institute, Saint-Petersburg, Russia gave us this recipe, they use it routinely and get good results

Good luck!
