[Histonet] Testes Bouin's fluid

Dear Dr. Balaji:

A few questions to clarify your problem:

How long were the testes fixed in Bouin?
Was fixation by immersion or perfusion?
How long was the tissue washed in 70% ethanol?
Why was the tissue 'refixed' in buffered formalin? Tissues properly 
fixed in Bouin should not need to be refixed.
Exactly what is it about the morphology/staining that is "not that great"?

Bouin's is an excellent fixative and, assuming it is made correctly and 
the tissues are fixed promptly and for sufficient time, the most likely 
source of your problems is not the fixative.
