Common types of high pressure steam sterilizers include lower exhaust pressure steam sterilizers and pulse vacuum pressure steam sterilizers. The difference between the two is mainly reflected in the sterilization temperature, pressure and time, and the sterilization effect There is not much difference.
The common materials of plastic vaccine bottles include polyethylene and polypropylene. The bottles that are sterilized by high temperature and high pressure are generally polypropylene. Because compared with polyethylene, this material has good high temperature resistance. Features, can meet the temperature requirements of this sterilization method.

Precautions for ethylene oxide sterilization of plastic vaccine bottles

 Ethylene oxide is a kind of sterilizing agent, which is suitable for the sterilization of items that cannot be soaked with disinfectant, dry heat, pressure, steam and other chemical gases. It is also a common sterilization method for plastic vaccine bottles. However, ethylene oxide is flammable and explosive, so the following points need to be paid attention to during the sterilization process:
