The volume of the fixative should be 20 times greater than the volume of the specimen
In order for the fixative to effectively diffuse through the tissue to fix, the tissue sample must be immersed in a fixative of a volume that is 15 to 20 times greater than the total volume of the specimen. Other options above are inadequate and cannot effectively fix the sample through immersion.
