Sterilizing units designed for total inactivation of microorganisms that are or may be present on medical devices using vapors from appropriate germicidal solutions (e.g., solutions having a low content of formaldehyde) with low humidity content. These units usually include a treatment chamber with shelves on which the devices to be sterilized are placed, usually after being cleaned of gross debris; means to introduce the vapor into the chamber; and controls to regulate the time of the procedure. After the sterilization cycle is complete an integral purging system to eliminate the vapor residues is usually activated. Vapor sterilizing units are available in a variety of shapes and sizes; usually as tabletop units. Vapor sterilizing units are used for devices and supplies that are sensitive to high temperature and humidity, such as plastic and rubber devices.
