What is the process of sterilization?
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. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic .

How does a glass bead sterilizer work?
Glass bead sterilizers work by heating glass beads to 250 °C (482 °F). Instruments are then quickly doused in these glass beads, which heat the object while physically scraping contaminants off their surface. Glass bead sterilizers were once a common sterilization method employed in dental offices as well as biological laboratories, but are not approved by the U.S. Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) to be used as a sterilizers since 1997. They are still popular in European and Israeli dental practices, although there are no current evidence-based guidelines for using this sterilizer.
What is UV light used for?
Ultraviolet light irradiation (UV, from a germicidal lamp) is useful for sterilization of surfaces and some transparent objects. Many objects that are transparent to visible light absorb UV. UV irradiation is routinely used to sterilize the interiors of biological safety cabinets between uses, but is ineffective in shaded areas, including areas under dirt (which may become polymerized after prolonged irradiation, so that it is very difficult to remove). It also damages some plastics, such as polystyrene foam if exposed for prolonged periods of time.
What is the purpose of nitrogen dioxide?
Nitrogen dioxide (NO 2) gas is a rapid and effective sterilant for use against a wide range of microorganisms, including common bacteria, viruses, and spores. The unique physical properties of NO 2 gas allow for sterilant dispersion in an enclosed environment at room temperature and atmospheric pressure. The mechanism for lethality is the degradation of DNA in the spore core through nitration of the phosphate backbone, which kills the exposed organism as it absorbs NO 2. This degradations occurs at even very low concentrations of the gas. NO 2 has a boiling point of 21 °C (70 °F) at sea level, which results in a relatively highly saturated vapour pressure at ambient temperature. Because of this, liquid NO 2 may be used as a convenient source for the sterilant gas. Liquid NO 2 is often referred to by the name of its dimer, dinitrogen tetroxide (N 2 O 4 ). Additionally, the low levels of concentration required, coupled with the high vapour pressure, assures that no condensation occurs on the devices being sterilized. This means that no aeration of the devices is required immediately following the sterilization cycle. NO 2 is also less corrosive than other sterilant gases, and is compatible with most medical materials and adhesives.
How does dry heat sterilize?
Dry heat was the first method of sterilization and is a longer process than moist heat sterilization. The destruction of microorganisms through the use of dry heat is a gradual phenomenon. With longer exposure to lethal temperatures, the number of killed microorganisms increases. Forced ventilation of hot air can be used to increase the rate at which heat is transferred to an organism and reduce the temperature and amount of time needed to achieve sterility. At higher temperatures, shorter exposure times are required to kill organisms. This can reduce heat-induced damage to food products.
What type of radiation is used to sterilize a substance?
Sterilization can be achieved using electromagnetic radiation, such as ultraviolet light, X-rays and gamma rays, or irradiation by subatomic particles such as by electron beams. Electromagnetic or particulate radiation can be energetic enough to ionize atoms or molecules ( ionizing radiation ), or less energetic ( non-ionizing radiation ).
What are the guidelines for sterilization?
These guidelines state that hinged instruments should be opened; items with removable parts should be disassembled unless the device manufacturer or researchers provide specific instructions or test data to the contrary 181; complex instruments should be prepared and sterilized according to device manufacturer’s instructions and test data; devices with concave surfaces should be positioned to facilitate drainage of water; heavy items should be positioned not to damage delicate items; and the weight of the instrument set should be based on the design and density of the instruments and the distribution of metal mass 811, 962. While there is no longer a specified sterilization weight limit for surgical sets, heavy metal mass is a cause of wet packs (i.e., moisture inside the case and tray after completion of the sterilization cycle) 963. Other parameters that may influence drying are the density of the wraps and the design of the set 964.
Why do sterilizers use biological indicators?
If a sterilizer is used frequently (e.g., several loads per day), daily use of biological indicators allows earlier discovery of equipment malfunctions or procedural errors and thus minimizes the extent of patient surveillance and product recall needed in the event of a positive biological indicator 811.
Why do spore tests occur sporadically?
They may occur for reasons such as slight variation in the resistance of the spores 983, improper use of the sterilizer, and laboratory contamination during culture (uncommon with self-contained spore tests).
