Steris plc is an American-Irish-based medical equipment company specializing in sterilization and surgical products for the US healthcare system. [3] Steris is operationally headquartered in Mentor, Ohio, [1] but has been legally registered since 2018 in Dublin, Ireland for tax purposes; it was previously registered in the United Kingdom from 2014 to 2018.
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 ...
Within the sterilizer, water flows as close as possible to the ultraviolet light source. Water pre-filtration is critical as water turbidity lowers UV-C penetration. Many of the better UV sterilizers have long dwell times and limit the space between the UV-C source and the inside wall of the UV sterilizer device. [117] [independent source needed]
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.

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 ...
The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour, and in the case of High Velocity Hot Air sterilisers, 190°C (375°F) for 6 to 12 minutes. [3] Items should be dry before sterilization since water will interfere with the process.
