[Histonet] Mercury free Gilson's fluid

[Jorge Tornero]

Hello all,

Does anyone know about a Gilson's fluid formula which is mercury-free? I've
been searching and I've found a paper on it in Histo-Logic Vol VI, Num 4,
October 1976 by Carolyn A. Barsczcz who  reccomends the use oz zinc chloride
in substitution of mercury chloride in zenker type fixatives (Gilson's fluid
seems to be of this kind), but I haven't been able to find formulas. ¿Any
suggestion?

Thank you very much
