PETG media bottle is a very transparent plastic bottle, which is mostly used to store solutions such as serum and culture medium. These solutions are commonly used in cell culture processes, so the packaging must meet the requirements of sterility to avoid contamination of the cells.
In terms of sterilization, PETG media bottles are generally sterilized by cobalt 60. Cobalt 60 sterilization is the use of 60Co γ-ray irradiation, acting on microorganisms, directly or indirectly destroying the nucleus of microorganisms, thereby killing microorganisms and playing a role in disinfection and sterilization. It is a kind of irradiation sterilization technology, and the γ-ray produced by the radioactive isotope cobalt 60 irradiates the packaged food. In the process of energy transmission and transfer, strong physical and biological effects are produced to achieve the purpose of sterilization.

60Co-γ ray irradiation sterilization is a special "cold processing" technology. It sterilizes at room temperature and has the advantages of strong penetration, uniform, thorough and rapid sterilization, no drug residues, and no environmental pollution. Sterilization of food. After sterilization, PETG media bottle will be sealed and packaged to ensure its sterility. If the package is not opened, the validity period is 3 years. If it is opened, please use it as soon as possible to avoid contamination.
The above is sterilization method of PETG media bottles. The purpose of sterilization is to kill the microorganisms on the bottle and avoid bringing these pollution sources into solutions such as serum and culture medium, which will affect the cell culture effect.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
