Moist heat sterilization describes sterilization techniques that use hot water vapor as a sterilizing agent. [ 1 ] [ 2 ] Heating an article is one of the earliest forms of sterilization practiced. The various procedures used to perform moist heat sterilization process cause destruction of micro-organisms by denaturation of macromolecules.
This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave, sometimes called a converter or steam sterilizer. The object or liquid is placed in the autoclave chamber, which is then sealed and heated using pressurized steam to a temperature set point for a defined period of time.
It is designed specifically to prove that the process achieved full temperature and time required for a normal minimum cycle of 134 °C for 3.5–4 minutes. [20] To prove sterility, biological indicators are used. Biological indicators contain spores of a heat-resistant bacterium, Geobacillus stearothermophilus.
"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 ...

The practice of reusing medical devices labeled for only one use began in hospitals in the late 1970s. [8] After a thorough review by the U.S. FDA in 1999 and 2000, [8] the agency released a guidance document for reprocessed SUDs that began regulating the sale of these reprocessed devices on the market, [9] under the condition that third-party reprocessors would be treated as the manufacturer ...
Dry heat sterilization of an object is one of the earliest forms of sterilization practiced. It uses hot air that is either free from water vapor or has very little of it, where this moisture plays a minimal or no role in the process of sterilization.
Process performance qualification protocol is a component of process validation: process qualification.This step is vital in maintaining ongoing production quality by recording and having available for review essential conditions, controls, testing, and expected manufacturing outcome of a production process.
