ETO Sterilizer is a very effective tool for sterilising medical equipment. The water ring rotary pumps are made to keep the chamber's ETO concentration at its ideal level. In order to prepare the environment for the ETO reprocessing procedure, it is also employed. Steam is used to continuously heat the chamber. ETO Sterilizer is a great process for a wide range of materials. The majority of medical device surfaces may be effectively penetrated by EO sterilization using a vacuum-based technique, and because of its lower temperature.
