Steam Sterilisation Services

23 February 2022


Steam Sterilisation Technology is a simple yet very effective decontamination method. Sterilisation is achieved by exposing products to saturated steam at high temperatures (121°C to 134°C). The device’s exposure time to steam would be anywhere between 3 to 15 minutes, depending on the generated heat.


By modifying temperature factors, pressure factors and humidity conditions, we can reach the balance point between the liquid and gas phase of the water. This allows for the creation of saturated steam which will immediately induce condensation on the surface of the product to sterilise.


ISO 17665 specifies requirements for the development, validation and routine control of a moist heat sterilization process for medical devices. Moist heat sterilisation processes covered by ISO 17665-1:2006 include but are not limited to:


  • Saturated steam venting systems
  • Saturated steam active air removal systems
  • Air steam mixtures
  • Water spray
  • Water immersion


✅  Medistri is fully qualified to perform Steam Sterilisation according to ISO 17665, ANSI & AAMI guidelines. 


For effective Steam Sterilisation it is critical that the steam covers all surfaces of the device. To ensure optimal conditions, our autoclaves have built in meters that display temperature and pressure conditions with respect to time. Biological indicator devices and Indicator tape which changes colour are also used to gauge the performance of the autoclave.
