Cell factories play an important role in large-scale cell culture in the fields of human vaccines, animal vaccines, cell therapy, and stem cells. Although they are the main consumables for cell culture, they also require the assistance of some accessories during use. Commonly used accessories include the following categories:

1. Sealing cover: There are ventilation holes on the top of the cover, which are mainly used in a carbon dioxide environment. The ventilation holes allow carbon dioxide in the environment to enter the cell factory, creating suitable growth conditions for cell growth.

2. Breathable cover: The cover has no ventilation holes and is mainly used in incubators and greenhouses without carbon dioxide. A sealed cover can prevent the invasion of external bacteria and help create a good growth environment for cell growth.

3. Hose: including general hose and welded hose, welded hose can be heat welded. Mainly used for liquid transfer.

4. Hose clamp: its function is to clamp the hose to control the flow rate of the liquid, or to achieve the effect of throttling.

5. Pipe joint: connect two different hoses, the common ones are Y-type and T-type.

6. Small hole conversion head: suitable for small hole cell factory or middle hole conversion cover, connecting hose for pipeline operation.

7. Conversion cover: generally includes a middle orifice conversion cover and a small hole conversion cover, which are used for connecting hoses.

8. Air filter: improve the air condition and control the liquid inlet speed.

When using cell factories for large-scale cell culture, the accessories used are mainly of the above categories, and equipment such as manipulators, incubators, racks, and carts may also be used.

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.
