Fixation and Fixatives (2)

For fixation to occur the fixative has to penetrate by diffusion to the centre of the specimen and then sufficient time has to be allowed for the reactions of fixation to occur Both diffusion time and reaction time depend on the particular reagent used and the optimum time will vary from fixative to fixative In busy diagnostic laboratories there is considerable pressure to reduce
