The wide application of plastic materials has played a positive role in promoting industrial and agricultural production, facilitating people's lives, and meeting scientific research needs. With the advancement of science and technology and the continuous improvement of various processing techniques, plastic cell culture roller bottles have gradually replaced glass bottles and become a trend.
Cell culture roller bottles are a kind of special consumables for cell culture work, and have been widely used in immunotherapy, biopharmaceuticals, stem cell therapy and other fields. The cell culture roller bottles are in the shape of a straight barrel with a narrow mouth, and the inner wall is used for the adherent culture of animal cells. With the help of the adjustment of the speed of the cell culture spinner machine, it can meet the conditions required for the culture of suspension cells or adherent cells, effectively increasing the cell culture area and promoting cell growth. The exchange with gas is beneficial to cell growth and collection, improving the yield of cell culture.
The initial cell culture roller bottles are mostly made of glass, and after each culture, they need to be soaked in acid and cleaned before they can be used again. The roller bottle made of glass is heavy, and it is a large bottle with a small mouth. It is extremely inconvenient to clean, time-consuming and laborious, and accidents such as spinner bottle breakage are prone to occur during operation. Therefore, light and non-fragile plastic materials have gradually replaced glass materials, and have been favored by many scientific research institutions and pharmaceutical companies.
The wide application of plastic materials is not only reflected in cell culture roller bottles, the original glass bottles are gradually replaced by plastic bottles in many fields such as pharmaceutical packaging and reagent bottles. In today's ever-changing era, the survival of the fittest is an unchanging market truth, and this sentence is also applied to the material update of cell culture roller bottles. The demand is constantly changing, and what manufacturers of cell culture consumables have to do is to continue to innovate, meet the current market demand, and focus on the future, so as to remain invincible in the fierce market competition.
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.
