Introduction to the sterilization method of PETG media bottles

PETG media bottles are a plastic storage container with high transparency, which are generally used to store serum, culture medium, buffer solution and other solutions. In order to avoid microbial contamination caused by the packaging, it will be sterilized, and this packaging is mainly sterilized by cobalt 60.

Sterilization is to ensure the removal or killing of all bacteria, viruses, fungi and other microorganisms on the PETG media bottles by various physical and chemical means, so as to achieve a sterility assurance level of 10-6, that is, to ensure the survival of microorganisms on an item The probability is only one in a million. Only in this way can microorganisms on the packaging be prevented from causing additional contamination of the contents.

PETG Media Bottles

Cobalt 60 sterilization is the use of 60Co γ-ray irradiation to act on microorganisms, directly or indirectly destroying the nucleus of microorganisms, thereby killing microorganisms and playing the role of disinfection and sterilization. It is a kind of radiation sterilization technology, and the gamma-ray produced by the radioactive isotope cobalt 60 is used to irradiate packaged food. In the process of energy transmission and transfer, powerful physical and biological effects are produced to achieve the purpose of killing insects, sterilizing bacteria and inhibiting physiological processes. 60Co-γ-ray irradiation sterilization is a "cold processing" technology. It sterilizes at room temperature. The γ-ray has high energy and strong penetrating power. It will not cause the temperature of the item to rise while sterilizing. It is also called cold processing. Sterilization.

Cobalt 60 sterilization method is a very mature sterilization method. It is not only used in PETG media bottles, but also widely used in food, medical equipment and other fields.
