[Histonet] Nuclear fast red counterstain

[Histology]

Hi all,

Has anyone experienced commercially pre-made Nuclear Fast Red having reddish crystals in it?  We use this as a counterstain for Prussian Iron and Melanin stains and we are seeing little crystals on the slide.  We have tried filtering the solution but we are still seeing this problem.  Any help would be much appreciated.

Thanks as always Histonet!!
