Employing a graded alcohol sequence assists to make certain gradual elimination of water Therefore mitigating damage to delicate tissues and undue tissue shrinkage that may come about if h2o have been to get taken off way too abruptly, By way of example by fast immersion in one hundred% alcohol. Starting at a reduced alcohol focus also prevents the precipitation of phosphate salts from phosphate buffered formalin. It is essential that the focus of the final Alcoholic beverages from the graded sequence is one hundred% so as to promote finish elimination of interstitial water within the tissues.
