[Histonet] Eosin Staining Issues

[kristen arvidson]

Hello All!
 
I am having some bizzare staining issues.  The eosin seems to be washing out??  The slides look "sun bleached" according to the Pathologists.  The problem is that it is only happening on occasion.   One rack stains fine and the next one has a problem.   It even appears to be  happening within cases staining in the same rack.  My first though is tap water ph.  We don't monitor that, haven't needed to,  we've never had a problem like this before.  Thoughts??  Thanks
