When cultivating cells, we often use the cell culture shaker Flasks as a lab tool. There are many kinds of tools used to culture cells, and this container has the following features:
1. Optimized design: the design of cell culture shaker flasks is optimized to provide a good environment for cell culture. It is usually triangular in shape and comes in different sizes (125 ml, 250 ml, 500 ml, 1000 ml) to meet the needs of different sizes of cell culture.
2. Suspension culture: This vessel is usually used with a shaker, which gently agitates the cell suspension, which helps to maintain a homogeneous suspension of cells, promotes uniform distribution of oxygen and nutrients, and prevents cell settling and aggregation.
3. Adaptability and adjustability: the cell culture shaker flasks is suitable for different types of cell culture, including animal cells, plant cells and microbial cells. According to different experimental needs, the stirring speed, temperature, CO2 concentration and other parameters can be adjusted according to requirements.
4. Stable culture environment: Cell culture shaker flasks usually have sealed lids or membranes, which can provide a stable culture environment. This helps to prevent contamination by external microorganisms and maintain proper temperature, humidity and gas composition in the culture medium.
Overall, cell culture shaker flasks, a common experimental tool, provides a good culture environment for cells through special design and is widely used in biomedical research, drug development, production and vaccine manufacturing.
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.
