To achieve the effect of sterilization; the front baffle of the drawer is provided with a sealing strip to ensure the air tightness of the main body of the sterilization box during the high-temperature steam process, thereby improving the experimental efficiency; the vent is set at the top center of the main body of the sterilization box , in the shape of a rectangle, to ensure that the high-temperature steam can spread evenly around the sterilization box; through the drainage port set on the underside of the sterilization box body, it is convenient for the high-temperature steam to condense and form a liquid that can be discharged from the sterilization box body, and it is also convenient for sterilization. Cleaning of the box body; there is a push-pull bar at the vent, which is convenient for quickly adding high-temperature steam into the sterilization box. When the high-temperature steam fills the entire sterilization box, the push-pull bar can be quickly closed, so that the sterilization box forms a closed The main body, drawer and handle of the sterilization box are made of glass or high temperature-resistant plastic transparent material, which is convenient to observe the sterilization situation inside the main body of the sterilization box. The utility model is simple and convenient to use and has strong practicability. The utility model is easy to popularize and use, and effectively solves the problem that a plurality of petri dish sterilization devices of different specifications need to be prepared to sterilize the petri dishes of different specifications when experiments of different specifications are carried out at the same time.
