PETG media bottle is a square storage container with very good low temperature resistance, suitable for various solutions that require low temperature storage, such as culture medium, serum, etc., in addition, it can also be used for the storage of cell cryopreservation solution.
Cell cryopreservation is one of the main methods of cell preservation. Using cryopreservation technology to store cells in liquid nitrogen at -196°C can temporarily remove the cells from the growth state and preserve their cell characteristics for a long time, and then resuscitate the cells for experiments when needed. At the same time, properly freezing a certain amount of cells can prevent the cells from being unable to continue to be cultured due to cell contamination or other accidents, which plays a role in cell preservation.
When freezing cells, cell cryopreservation solution is a ready-to-use low-temperature solution for culturing cells to protect cells. This solution needs to be stored frozen at -20°C, and the validity period is generally one year. If stored at 4°C, the validity period is at most 3 months. PETG media bottle is made of PETG raw material through injection stretch blowing process, which can withstand low temperature of -70 ℃, and is a good packaging container for low temperature storage solution. The bottle body has high transparency, and the molded scale is convenient for observing the capacity of the solution, and the square design is easy for the operator to grasp.
The above is the application of PETG media bottle in cell cryopreservation solution. No matter what kind of solution is used for storage, its airtightness is a problem worthy of attention. Only a well-sealed packaging container can ensure the stability of the solution.
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.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
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.
