In biopharmaceuticals, the storage and transfer of liquids are often involved, and carboys provide a lot of convenience for this operation. Its large-capacity design, high temperature and high pressure resistance and other features are favored by many scientific research institutions and pharmaceutical companies. So, can this kind of container be reused? Let’s find out the answer together.

The commonly used raw materials for carboys are PP and PC. From the perspective of chemical properties, they both have good corrosion resistance and are resistant to most acid and alkali solvents. This kind of liquid storage container has a large capacity, with common specifications of 10L and 20L, which can meet the needs of large-capacity storage and transfer of liquids, especially in the large-scale culture stage of cells.

From the perspective of temperature resistance, both PP and PC materials can withstand high-temperature and high-pressure sterilization. This sterilization method is also commonly used by biological products companies, so this liquid storage container can be reused. In order to avoid cross-contamination and ensure the safety of liquids, strict cleaning and disinfection are required after each use to ensure their hygiene and integrity.

Taken together, the carboy has the property of being reused, but it should be noted that during high-temperature and high-pressure sterilization and multiple uses, the surface of the container may be damaged. We must regularly check the status of the container and make decisions based on specific circumstances. The number of reuses is limited and it is not easy to reuse it too many times to avoid any impact on the production process or test results.

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.
