Slightly hypertonic fixative
The type of fixative that gives the best result in fixation is the slightly hypertonic fixative. This is for the reason that the osmolality of a slightly hypertonic fixative is between 400-450mOsm, which gives the best result in fixation. Hypertonic fixatives causes shrinkage of the cell, while isotonic and hypotonic fixatives give rise to the swelling of the cell and the fixation quality becomes poor.
