Acetone
The substance that is used as a fixative and as a dehydrating agent is acetone. Acetone has been used as a dehydrating agent in tissue processing. It is rapid-acting in nature but makes the tissue much more fragile if it is exposed extensively to acetone. Recent developments have also utilized acetone as a fixative in a technique known to combine acetone, methylbenzoate, and xylene. This requires overnight fixation of tissues in acetone at -20 degree Celsius. Other choices do not possess these two qualities.
