The carboys are a large-capacity liquid storage container. Our common specifications are 10L, 20L, etc. It is mainly used to store sterile liquids, distribute solutions and culture media. In biopharmaceutical processes, they are often used to store stock solutions.

In the biopharmaceutical process, after the expansion of the cell culture medium is completed, the original solution needs to be harvested for the next step of the process. Since the volume of the original solution after amplification is generally very large, large-capacity packaging such as carboys are used for harvesting. After harvesting, it goes through deep filtration, inactivation, purification and other processes, and then is diluted according to a certain ratio to make vaccines or drugs.


Commonly used materials for carboys include polypropylene and polycarbonate. Both materials have very good chemical stability and can withstand corrosion from most acid and alkali solvents, ensuring that the solution will not react with the container during storage. For easy access, there is a handle on the carboys. This kind of container can withstand high temperature and high pressure sterilization and can be reused, saving the company's costs. The barrel has molded scales to facilitate the distribution and use of liquids. Produced by the injection stretch blow molding process, this storage container has a better appearance and overall sealing performance.

The above is the application of carboys in raw liquid harvesting. For the field of biopharmaceuticals, this container is an easy-to-use and cost-effective tool. In order to facilitate liquid transfer, it is equipped with a variety of liquid conversion caps and sealing caps to satisfy of different needs.

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.
