There are two types of filters used in filtration sterilization: (a) Depth filters: (b) Membrane filters: These are porous membrane about 0.1 mm thick, made of cellulose acetate, cellulose nitrate, polycarbonate, and polyvinylidene fluoride, or some other synthetic material. Clipping is a handy way to collect important slides you want to go back to later. Hydrogen peroxide. On average, the microorganisms may range from 10-2,000/m 3 while the suspended particles may be 20-100,00/ m 3. Sugar solutions used for the cultivation of microorganisms tend to caramelise during autoclaving and so they are best . Porosities of membrane filters range from 0.1m to 10m and the most commonly used membrane filter has the pore size of 0.22m and 0.45m. The establishment of process parameters and tolerances; 3.
