   Eosin is differentiated in the dehydrating alcohols.  You ca   the  time  in  the  alcohols to get a lighter pink.  Also contact   tech  support  at  Richard-Allan.   There are two types of eosin that   they sell and one is really concentrated.

          pink?  I     after  Eosin  or  if     pinker....it's  more  orange when      alcohol  in  the  alcohol  after  eosin(just see     anyway).   If  it's just too strong, dilute it down wi     I  hardly  get  any specimens, so I don't like changing the      often,  i  just  keep  adding  alcohol  to  it when it gets low and
     crusted      Mark T.
