Serum contains plasma proteins, polypeptides, fats, carbohydrates, growth factors, hormones, inorganic substances and other substances, which are essential for promoting cell growth. There are many types of serum, and fetal bovine serum is one of the higher quality ones. What requirements should PETG media bottles be used as storage containers?

Fetal bovine serum refers to the light yellow transparent liquid separated from the plasma after removing fibrinogen and some coagulation factors from the blood after blood coagulation by cardiac puncture of fetal bovines or artificially induced fetal bovines or referring to fibrinogen. Plasma that has been removed. Fetal bovine serum contains the nutrients and factors required for a relatively complete cell culture system. Due to less external contamination factors, shorter exposure time in the environment, less access, and very scarce sources. In summary, the price of fetal bovine serum is much higher, and it is usually used for scientific research cell culture or for cell lines with higher culture conditions.

PETG media bottles

Fetal bovine serum is generally stored at -5°C to -20°C, if stored at 4°C, it should not exceed one month. Therefore, the first requirement for PETG serum is the low temperature resistance of the material, so as to meet the storage requirements of the serum. Secondly, in the cell culture test, the serum is generally added several times, so the design of the packaging should take into account the ease of grasping, and most of them are square on the market.

The requirements of fetal bovine serum for PETG media bottles are mainly low temperature resistance and easy to grasp. In addition, in order to facilitate the observation of serum capacity, there will be a scale on the bottle body.

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.
