Typical steam sterilization cycles are between 3 and 30 minutes at 121–134 °C (250–273 °F) at 100 kPa (15 psi), but adjustments may be made depending on the bioburden of the article being sterilized, its resistance to steam sterilization, the article's heat tolerance, and the required sterility assurance level. Following the completion of ...
Koch's or Arnold's steam sterilizer: used for steam sterilization A pressure cooker: used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter:
Sterilization autoclaves are widely used in microbiology and mycology, medicine and prosthetics fabrication, tattooing and body piercing, and funerary practice.They vary in size and function depending on the media to be sterilized and are sometimes called retort in the chemical and food industries.
"F 0" is defined as the number of equivalent minutes of steam sterilization at temperature 121.1 °C (250 °F) delivered to a container or unit of product calculated using a z-value of 10 °C. The term F-value or "F Tref/z " is defined as the equivalent number of minutes to a certain reference temperature (T ref ) for a certain control ...
Pressure sterilization is the prevailing method used for medical sterilization of heat-resistant tools, and for sterilization of materials for microbiology and other fields calling for aseptic technique. [citation needed] In cases when items need to be sterilized for immediate use, flash sterilization may be employed. [3]
Sterilization can also be achieved using ethylene oxide (ETO) gas. This process was created in the 1950s by the US military [4] and is used on items that cannot withstand the high temperatures of steam sterilization. ETO sterilization takes far longer than steam sterilization and is hazardous to workers, so alternative methods were created in ...
A BIER vessel evaluates the resistance of biological indicators to moist heat sterilization. [1] For example, if a 90% reduction is determined to be 5 minutes for the microorganism being evaluated, then a D-value of 5 is assigned. D values are specific to starting bioload, substrate (the material the spores are on), and microbe species.
Sterilization may refer to: Sterilization (microbiology), killing or inactivation of micro-organisms; Soil steam sterilization, a farming technique that sterilizes soil with steam in open fields or greenhouses; Sterilization (medicine) renders a human unable to reproduce; Neutering is the surgical sterilization of animals
