Sterilization (microbiology) equal to the probability of a non-sterile unit. For high-risk applications, such as medical devices and injections, a sterility assurance level of at least 10 is required by the United States Food and Drug Administration (FDA). A widely used method for heat sterilization is the autoclave, sometimes called a converter or steam sterilizer. Autoclaves use steam heated to under pressure. To achieve sterility, the article is placed in a chamber and heated by injected steam until the article reaches a temperature and time setpoint. Almost all the air is removed from the chamber, because air is undesired in the moist
Undine (medical) As glass undines require careful cleaning and sterilization after each use, single-use plastic equivalents were preferred as they are cheaper and require no careful handling. Undine (medical) An undine is an ophthalmic irrigation device which was used to trickle a cleansing liquid over the conjunctival surface while controlling the flow with the thumb or finger over the filling hole.
