Sterilization refers to any process that removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example, food or biological culture media. Filtration is an interesting sterilization method in laboratories. It’s the only method that uses force to separate rather than to kill. When you filter a liquid or gas, it passes through a pore, which stops, or filters out, the passage of larger particles. Filtration depends on pore sizes, the smaller the pores the more particles it can screen out, but it also takes more energy to force the liquid through it. Pore sizes can be as small as .01 μm (μm=micrometer), small enough to stop viruses from passing through, but smaller proteins can still get through. There are even really small filters called nano-filters, which stop viruses, proteins, and some toxins. In laboratories, liquids are filtered through microbial filters to remove any microbes present. It is an effective method of sterilization for heat-sensitive liquids. There are four types of filters: (1) Membrane filters are thin filters that are made of cellulose. They can be used for sterilization during injection by placing the membrane between the syringe and the needle. (2) Seitz filters are usually made of asbestos. They are pad-like and thicker than membrane filters. (3) Sintered glass filters are an alternative type of filter that are made of glass and hence do not absorb liquids during filtration. (4) Candle filters are made of clay-like mud. This special mud has tiny pores made by algae. The microbes get stuck during their travel through the pores.
