According to the standard plastination procedures, complete dehydration of formalin fixed specimens by acetone can normally be achieved at -25°C and the forced impregnation of specimens with silicone polymers can be done only at -15 C to -25°C in a deep freezer. According to the present study now, we have been able to modify the dehydration procedure and use room temperature for dehydration and forced impregnation.
