Plastic vaccine bottles are the main packaging of inactivated animal vaccines. Vaccines are different from ordinary items. They have strict requirements on packaging. Among them, sterility is a very important point. In the way of sterilization, this kind of packaging will choose cobalt 60 irradiation sterilization.
Cobalt 60 irradiation sterilization is the use of 60Coγ-ray irradiation, which acts on microorganisms, directly or indirectly destroys the nucleus of microorganisms, thereby killing microorganisms and playing a role of disinfection and sterilization. It is a kind of radiation sterilization technology. The gamma rays produced by the radioactive isotope cobalt 60 irradiate packaged food. In the process of energy transfer and transfer, it produces powerful physical and biological effects to achieve the purpose of killing insects and sterilization.
Cobalt 60 irradiation sterilization has the advantages of strong penetration, uniform, thorough and rapid sterilization, no pollution to the environment, low cost and low energy consumption. The plastic vaccine bottle sterilized by this method can achieve a good sterilization effect without There will be drug residues. In my country, a national standard has been formed for cobalt 60 sterilization technology. The current implementation is the GB10252-2009 "Radiation Protection and Safety Specifications for Gamma Irradiation Devices" standard, which is a relatively mature sterilization method.
Cobalt 60 irradiation sterilization is only one of the many sterilization methods for plastic vaccine bottles. Others include high temperature and high pressure sterilization and ethylene oxide sterilization. The specific sterilization method to choose depends on the requirements and requirements of the veterinary drug manufacturer. Depending on the characteristics of the vaccine.
