Cell culture roller bottles are commonly used experimental equipment in the field of life science research, and are used to culture and expand biological cells in vitro. Compared with other culture methods, cell culture roller bottles have the following advantages:
Controllable volume: The common volumes of cell culture roller bottles are 2L and 5L. The volume is controllable, which is convenient for flexible adjustment and high-throughput experimental design.
Reasonable design: It has a scientific and reasonable structural design, which promotes gas exchange and full convection of the culture medium through slight rotation, which is beneficial to the needs of cell nutrition, metabolism, and gas exchange.
Two surface options: This kind of consumables generally have two surface options: flat and expanded. Among them, the special design of the surface of the expanded roller bottle increases the cultivation area, and has become the choice of more and more enterprises.
Simple operation: The cell culture process of this consumable tends to be standardized, and it is easy to obtain products of the same quality. In addition, it is easy to use, just add cells and culture medium to carry out cell culture.
Inexpensive: Compared to other cell culture vessels, the relatively low price of cell culture roller bottles makes them commonly used in scientific laboratories. In addition, this kind of container has good reusability and can be used multiple times if the operation steps are followed, which can save experimental costs to a certain extent.
Taken together, the cell culture roller bottles are a scientifically reasonable, inexpensive, easy-to-operate, and widely used cell culture container, and it is an important tool for life science researchers to carry out in vitro culture.
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.
