Cell culture shake flasks are specialized containers designed for cell cultivation, particularly playing a crucial role in suspension cell culture. Here are some key characteristics:
Unique Design: Cell culture shake flasks typically feature a cap with breathable membranes, ensuring gas exchange for cells while preventing contamination. The design of breathable membranes also ensures the stability of the flask's internal environment.
Suitable for High-Density Cultivation: The cap and neck design of Cell culture shake flasks often consider the high-density cultivation needs of cells. Large breathable membrane areas on caps facilitate adequate oxygen supply, while the neck design enables easy one-handed handling.
Excellent Materials: These cell culture containers are usually made of polycarbonate (PC) or PETG materials free of bisphenol A, offering excellent mechanical properties, fatigue resistance, dimensional stability, and high-temperature resistance.
Sterile and Contamination-Free: Flasks undergo rigorous sterilization processes such as irradiation to ensure sterility during production. Additionally, their design includes measures to prevent cross-contamination.
Easy Operation: The design of Cell culture shake flasks typically considers user-friendliness, with clear and accurate markings for easy observation of culture medium volume. The standard size of the flask mouth facilitates compatibility with other equipment.

Used with Shakers: They are usually used in conjunction with shakers to provide an optimal growth environment for cells by controlling rotation speed and shaking method.
In summary, the design of Cell culture shake flasks considers multiple factors, including the needs of cell growth, user convenience, sterility, and safety, providing an efficient, stable, and reliable tool for cell cultivation.
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.
