PETG media bottle is a widely used plastic bottle. It has a highly transparent body, a square design, light weight, and is not easy to break. It is a good storage container. Our common applications are mainly the following three:
1. Serum: Serum provides cells with basic nutrients, growth factors, binding proteins, etc., to avoid mechanical damage to cells, and to protect cells in culture. Serum that needs to be stored for a long time is stored in a low temperature environment of -20℃ to -70℃. If stored in a 4°C refrigerator, generally no more than 1 month.
2. Culture medium:
The medium generally contains carbohydrates, nitrogenous substances, inorganic salts, vitamins and water, etc., which are not only the basic substances that provide cell nutrition and promote cell proliferation, but also the living environment for cell growth and reproduction. The storage environment of the medium is 2°C-8°C, protected from light.
3. Various reagents: In addition to the storage of serum and culture medium, PETG serum bottles can also be used as storage containers for various biological reagents, such as buffers, dissociation reagents, antibiotics, cell cryopreservation solutions, staining solutions, growth additives, etc. Some of these reagents need to be stored at -20°C, while others are stored at room temperature. No matter which environment, serum bottles can meet their storage requirements.
The PETG media bottle is mainly used to hold the above three solutions. In order to visually observe the volume of the solution, there is a scale on the bottle body. The above solutions are basically used in cell culture, and attention should be paid to aseptic operation when adding them.
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.
