Re: whole organ fixation with color retention
My suggestion is to slice the organs, fix in buffered
formalin or Wentworth's fixative (see most
histotechnology textbooks for the formula) for 4 weeks
or more. Mount specimen in a perspex museum box. Rinse
specimen in 95% ethanol and leave in ethanol untill
colour comes back (brown bloody areas appear red),
replace ethanol with light paraffin oil, seal the box,
label and all done.
