Pharmaceutical Ethylene Oxide (ETO) Sterilizers Manufacturing for Hospital & medical college, Laboratories, blood banks. ETO method is used to medical equipment and pharmaceutical products that cannot support high temperature steam sterilization materials that may be deteriorated by radiation sterilization.

Ethylene oxide (ETO) – Sterilization Process for Pharmaceutical

Ethylene Oxide has high penetrating power and passes through and sterilizes large packages of materials including plastics. it is liquid at temperatures below 10.8oC.Eto

ETO used for Gas sterilization is mixed with diluents such as nitrogen in different proportions from 10 % Ethylene Oxide to 90 % Ethylene Oxide to eliminate explosive tendency.

It is used for products that cannot with stand the heat of typical autoclave sterilization such as plastic. The physical parameters to be monitored are temperature and relative humidity.

Ethylene Oxide (ETO) sterilizer cycles are run in chambers which are scaled to prevent the leak of ETO gases into the atmosphere. ETO process to perform a mapping of chamber and moniter temperature and relative humidity to evaluate the performance of ETO sterilization. Both empty and loaded chamber are required.

ETO sterilization is:

  • Low temperature
  • destroys microorganisms including resistant spores
  • Large sterilizing volume capacity
  • plastic, metal and rubber materials.
