Dear Histonetters,  
Has anyone had any problems with a purple- blue haze on their H&E  using
Richard Allen Scientific Hematoxylin 7211.  I am currently filtering it.  I
am still getting the haze.  I have changed nothing,  it just appeared a
couple of weeks ago.  Any help would be greatly appreciated.
 
Happy Holidays,
