Vaccine safety is related to people's livelihood, so it is imperative to carry out more stringent supervision of vaccines. To monitor vaccines, the first thing is to monitor their production and quality. Vaccine production is a complex and sophisticated matter. Any error in the middle may lead to problems in vaccines, and the general problem vaccines also appear in the production process.
At the same time, the vaccine has to go through the above checks before it can enter the market, and after circulation, it has to accept the sampling inspection of the relevant departments. During this period, scientific testing methods and advanced packaging testing equipment have contributed to the quality control of the vaccine.
The Polariscopes developed and produced by Suzhou PTC Optical Instrument Co., Ltd. can qualitatively and quantitatively test the internal stress of glass, and can directly read the results. It is used for the polarized light measurement of the internal stress value of ampoules of various capacities required by the new version of drug packaging materials and the quantitative measurement of the internal stress of various glass vials, infusion bottles, pre-filling bottles, etc., which meet the requirements of the new version of drug packaging materials.
