Cell culture is also called cell cloning technology, which refers to a method that simulates the internal environment (sterile, suitable temperature, pH, and certain nutritional conditions, etc.) in vitro to make it survive, grow, reproduce and maintain its main structure and function. To achieve the conditions required for cell growth, cell consumables are needed. Cell culture flasks are a commonly used type.

Cell culture flasks have the characteristics of rich types and optional caps. According to different shapes, it can be divided into square bottles, rotating bottles, triangles, torticollis, etc. Each bottle has its own characteristics and corresponds to different cell culture needs. From the perspective of cell adhesion requirements for products, it is divided into three types: ordinary type, standard type and special type. For example, the special type contains nitrogen-containing functional groups on the surface, which can promote the adhesion and growth of certain special cells (such as tumor cells). And differentiation. It is worth noting that the culture of adherent cells requires TC surface treatment on the culture flask to adapt to the adherent growth of cells.

The caps of cell culture flasks are divided into sealed caps and filter caps. Sealing caps are often used for airtight culture, and open cultures when the bottle cap is unscrewed. The filter cover is suitable for open culture. The 0.2um hydrophobic filter membrane is installed in the cover to avoid possible cross-infection during the gas exchange process. It is generally recommended for carbon dioxide incubator culture, especially for experiments that require long-term culture.

These characteristics of cell culture flasks are based on the needs of current cell culture work. These demand points will continue to change according to technological progress, and cell culture flasks will also be updated and iterated on this basis.

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.
