Common specifications of cell culture roller bottles

The cell culture roller bottles are a disposable container that can meet the requirements of large-scale production of cells and tissues in both experiments and industrial production. It is widely used in the cultivation of animal and plant cells, bacteria, viruses, etc. With the continuous upgrading of technology, this culture tool is mostly used in the field of animal vaccine production. Do you know what common specifications it has?

According to different culture scales, cell culture roller bottles have two commonly used specifications of 2L and 5L, and the culture areas are 850cm2 and 1700cm2 respectively, among which the 2L bottle has two options of flat and folded, and the culture area of the folded inner wall is 1700cm2, which is equivalent to a 5L bottle. The bottle body is made of USPVI-compliant medical-grade transparent polystyrene (PS) material, and the vacuum plasma surface treatment process enhances the ability of cell adhesion, and the inner surface can also be coated with collagen according to customer requirements.

Cell Culture Roller Bottles

Injection stretch-blowing one-time molding process, the product bottle mouth is smooth and round, the contact seal with the bottle cap is better, and the product residue is less. The 5L cell culture roller bottle adopts a 2-stage design to increase the contact area. The contact area between the roller bottle and the roller bottle machine adopts a frosted structure, which increases the friction coefficient of the spinner bottle and reduces the phenomenon of roller bottle slippage.

The above is the introduction of common specifications of cell culture roller bottles. The selection of specifications depends on the experimental needs and the characteristics of the cells. When choosing a culture tool, we should take into account the number of cells needed, the size of the container, and the preparation materials, etc., so as to better meet the requirements of the experiment.

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.
