In biological laboratories, we often have to store various solutions and reagents. Thanks to the advantages of good performance, transparency, and temperature resistance, serum bottles have become "frequent visitors" in the laboratory. As a commonly used storage container, what are its common specifications?
Common materials for serum bottles include PETG and PET, both of which have very good temperature resistance and transparency. In comparison, bottles made of PETG have more advantages in terms of barrier properties. If you want to pursue a better storage state of the solution, it is recommended to use a bottle made of PETG. There is a molded scale on the body of the bottle, we can clearly observe the capacity and state of the solution.
The common specifications of this kind of container include 5ml/10ml/30ml/60ml/125ml/250ml/500ml/1000ml, etc., which are mostly used to store serum, culture medium, buffer, dissociation reagent, cell cryopreservation solution, growth additives and other solutions. It is worth mentioning that in order to facilitate the transfer and use of liquids, it can also be equipped with three-way or two-way caps and pipelines to achieve aseptic transfer of liquids and reduce the risk of solution contamination.
The different specifications of serum bottles meet the storage needs of different solutions, which is one of the main reasons for their wide application. In addition, this kind of container also adopts a square bottle design, which is mainly due to the consideration of human mechanics, so that the experimenters can better hold the bottle. Fudao Cell supplies serum bottles of various specifications, welcome to consult and negotiate.
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.
