The medium contains various nutrients required for cell growth and is an essential item for culturing cells. Although there are various types of media, PETG media bottles are mostly used in the selection of packaging, such as complete media.
After the basal medium is added with serum, antibiotics and other substances, it is called complete medium, also called (serum) cell culture medium. The basal medium can only maintain the survival of the cells. In order to make the cells grow and reproduce, it is necessary to add a natural medium. The commonly used bovine serum is bovine serum, because bovine serum contains various growth factors that promote cell proliferation and a variety of other benefits that are beneficial to cells. Substances that survive. In addition, in order to prevent contamination, a certain amount of antibiotics should be added to the culture medium. According to the amount of serum added, complete medium can be divided into cell growth medium and cell maintenance medium, which are used for different cells and different studies.
PETG media bottle is a kind of packaging container processed from PETG raw material. This raw material has very good transparency and is resistant to corrosion by most acid and alkali solvents. It is a good packaging material. There is a mold scale on the bottle body, which makes it easy to observe the solution of the medium and accurately control the dosage of additives. The storage environment of the complete medium is generally 2℃-8℃, and it is stored in the dark. The good temperature resistance of PETG material can meet its storage needs.
In addition to the storage of complete medium, serum and other solutions, PETG media bottles can also be used for the storage of buffers, cell freezing solutions and various biological reagents.
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.
