Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

Sterile dental instruments from hospital central supply (barcoded label indicating sterilization date, expiry date and contents). The central sterile services department (CSSD), also called sterile processing department (SPD), sterile processing, central supply department (CSD), or central supply, is an integrated place in hospitals and other health care facilities that performs sterilization ...
Disinfection uses liquid chemicals on surfaces and at room temperature to kill disease-causing microorganisms. Ultraviolet light has also been used to disinfect the rooms of patients infected with Clostridioides difficile after discharge. [14] Disinfection is less effective than sterilization because it does not kill bacterial endospores. [15]
The American Nurses Association and American Association of Nurse Anesthesiology set guidelines for sterilization and disinfection based on the Spaulding Disinfection and Sterilization Classification Scheme (SDSCS). The SDSCS classifies sterilization techniques into three categories: critical, semi-critical, and non-critical. [11]
Some computer-controlled autoclaves use an F 0 (F-nought) value to control the sterilization cycle. F 0 values are set for the number of minutes of sterilization equivalent to 121 °C (250 °F) at 103 kPa (14.9 psi) above atmospheric pressure for 15 minutes. Since exact temperature control is difficult, the temperature is monitored, and the ...
Heat treatment can be used for disinfection and sterilization. [42] The phrase "sunlight is the best disinfectant" was popularized in 1913 by United States Supreme Court Justice Louis Brandeis [43] and later advocates of government transparency.
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores.
