Terminal sterilization of parenteral drug products is performed at 121 C when possible. Rather than destroying contaminating microorganisms, it simply removes them. Besides porosity, other factors also influence the efficiency of filtration, they are: Filtration of liquids is accomplished either by pulling the solution through a cellulose acetate or cellulose nitrate membrane with a vacuum (i.e, by applying negative pressure on the filter paper) or by forcing the solution through the filter paper by imposing positive pressure above the fluid. Upon exposure, these waves are absorbed by many materials, particularly nucleic acids. Membrane filters are often used in combination with a coarse-grade fibre glass depth prefilter to improve their dirt-handling capacity.

As the sound waves propagate through a detergent solution, these ultrasonic waves produce alternating tensile and compressive forces that oscillate, and these oscillating forces cause millions of microscopically-sized cavities to form in the detergent solution. Non-ionizing waves have a very little penetration power, so microorganisms only on the surface are killed. Filter Sterilization It uses the principle of conduction in which the heat is first absorbed by the outer surface and is then passed into the inner layer.
